Shark has just dropped a brand new appliance into its lineup: the Shark BreatheClear with NeverChange6 Air Purifier (£269.99 at Shark). And as someone who tests air purifiers for a living, it’s got me pretty excited.

Of course, Shark has already proved it has what it takes to produce some of the best air purifiers on the market, understanding that UK homes crave an appliance to tackle dust, odours, and other airborne nasties that can affect our air quality.

But this new model solves the biggest (and most expensive) problem I have with this summer essential: how often you have to change your air purifier filter. And as the name suggests, the BreatheClear with NeverChange6 filter doesn’t have to be replaced for a whopping six years…

Shark impressed me last year when I tested the predecessor to this new model, the Shark NeverChange5 Air Purifier. With this older appliance, Shark had designed a reactive, powerful, and incredibly easy-to-use model.

The new Shark BreatheClear with NeverChange6 Air Purifier, however, takes what I loved about the NeverChange5 and supercharges it, offering a larger recommended room size and air changes per hour (70m2 with 1 air change per hour and 14m2 with 4.8 air changes per hour).

This makes it suitable for medium-sized rooms if you’re wondering how to choose an air purifier for your home. It also comes with an anti-odour cartridge to enhance the benefits of air purifiers, and it is available in two colourways to suit your home and style.

Personally, I still can't decide if I like the overall modern design or if it’s a bit too robotic for me. But that's all personal preference.

But the real selling point is that the advanced HEPA filter, which captures 99.98% of particles, doesn’t need to be replaced for 6 years. And this will save you a lot of money, as most air purifier filters need to be replaced regularly - costing you an extra chunk of money at least once or twice a year.

To calculate just how affordable that is over six years compared to other air purifiers, you can use the following formula: the price of the air purifier + (the price of the filter × 12). This is based on the assumption that you should generally change your air purifier filter every six months. However, it’s important to note that the exact lifespan depends on your usage.

But if you don’t want to do the maths, I’ve worked out a few examples below that compare the cost of the new Shark BreatheClear Air Purifier with the Blueair 3250i, which is Ideal Home's best overall air purifier, and our top budget model, the COWAY Airmega 50.

So, while it’s fair to say that you’ll have a higher upfront cost with the new Shark air purifier, it works out even cheaper than a budget-friendly model in the long run.

However, it’s important to note that this comparison only compares the air purifier's price and doesn’t account for its features and specifications. It may be that a different model will better suit your specific air quality requirements, so I’d still suggest doing your own research, depending on whether you want an air purifier to stop dust, tackle cooking smells, combat hay fever symptoms, or reduce pet dander.

But if you’re basing your air purifier purchase on price alone, I do think Shark’s new model is a worthy contender and my new unexpected hero of the summer.

Will you be snapping one up?

Air purifiers are just for allergy-sufferers, right? Well, that’s what I used to think, too. But then I started testing them as part of my day job, and I quickly realised that they offer so much more. And now I’ve spent the past few years with (at least) one in my home at all times, I don’t see myself ever living without one again.

Yes, you’ll probably know that the best air purifiers have been the talk of the town in recent years - especially during the spring and summer months when hay fever and seasonal allergies wreak havoc on those who struggle with scratchy eyes and sniffly noses. And while there’s no denying that air purifiers help to ease hay fever symptoms, that’s not all they do.

In my opinion, not enough people know just how impressive and versatile air purifiers can be, which is why I’m sharing the unexpected ways I use my air purifier around the house - so you can make the most of them too.

1. They can remove unwanted smells

As well as removing airborne particles from the air, many air purifiers can also remove smells, which I find to be a game-changer when I’m cooking something particularly stinky or the wet dog smell is just too much to handle. However, it’s important to note that not all air purifiers will do this.

If you want to make the most of these odour-busting properties, you’ll need to look closely at the filter specifications. This is echoed by Daikin’s residential property manager Hamid Salimi, who says, ‘Some air purifiers are equipped with activated carbon filters that can help eliminate unpleasant odours, such as cigarette smoke, cooking smells and household chemicals or pet odours.’

Some air purifiers like the Shark NeverChange 5 Air Purifier (£249 at Amazon) even go the extra mile by releasing a delicious scent into the air while it’s working its magic, too. This, coupled with the activated carbon layer, meant that this air purifier tackled cooking smells in a matter of minutes during testing - and it made my house smell amazing in the process.

2. They can keep dust at bay

I don’t know about you, but I find dusting to be one of the most tedious cleaning tasks out there, and I used to spend hours every week trying to get rid of dust in my home. However, that timeframe has drastically reduced since I started using an air purifier in my home.

It’s important to note that an air purifier can’t completely stop dust, as everything from opening windows to bringing shoes inside the house and even your own dead skin cells can create dust. But an air purifier can capture these dust particles inside the home and prevent them from re-entering your breathing space. You just need to make sure you choose one with a HEPA (high-efficiency particulate air) filter.

During the spring and summer months, when I find dust levels most aggressive, I tag-team my air purifier with my damp dusting schedule, and I find it’s an effective and efficient combo for dust removal. In fact, I couldn’t live without my Scrub Daddy Damp Duster (£2.99 at Amazon).

3. They can be candle-friendly

In my role as Ideal Home’s Air Quality expert, I conducted a very shocking candle burning test a little while ago. Unfortunately, the results of this test weren’t positive, and it definitely broke my heart as a candle lover. That’s because burning candles in the home releases dangerous levels of smoke and fine particulate matter, as well as volatile organic compounds (VOCs) often found in the wax and wick.

Personally, that hasn’t stopped me from burning them, but I have taken precautions and now use an air purifier alongside my candles to capture these particles before they linger too long in my breathing space. However, the best course of action is to use alternatives according to the pros, such as a candle warmer like this Candeldo Candle Warmer Lamp (£27.99 at Amazon).

Lars Dunberger, Technology Development Manager for Blueair, suggests, ‘For those who love the fragrance of candles without the pollution, a candle warmer is a great alternative. It releases the scent of the candle without combustion, meaning no smoke, soot or harmful emissions. Pairing a candle warmer with an air purifier offers the best of both worlds: the cosy ambience of candles with cleaner, healthier air for you and your family.’

4. They can help you sleep better

This unexpected perk of air purifiers is true for me, but I should note that this might not be the case for you. However, the science behind it makes sense on paper, as removing airborne pollutants can ease congestion and improve breathing, ultimately helping you sleep better.

There are even some air purifiers out there - like the Blueair Mini Restful Sunrise Clock Air Purifier (£139 at Amazon) - that are designed specifically with your sleeping schedule in mind. Not only will it work hard to improve your air quality levels at night, but the sunrise light and soothing sounds can help you ease out of a deep sleep more naturally. And after testing it out for myself, I can vouch for its effectiveness.

Personally, I find the gentle hum of an air purifier helps me fall asleep more quickly, too. But if you’re more sensitive to sound, Lars says you need to be picky. ‘If you’re planning to have your air purifier in your bedroom or have it on in the background while you work, checking the noise level is crucial. The number to look out for here is the dB(A) score, and the lower this is, the better.’

5. They can make a home pet-friendly

My in-laws are allergic to dogs that shed, so we probably should have adopted a hypoallergenic dog instead of a shedding cocker spaniel. But you know what they say: the dog chooses the human! And as a result, I’ve spent the past four years tackling pet dander in my home to ensure my in-laws’ symptoms are as minimal as possible.

This has been made so much easier with an air purifier, and experienced vet and VetMedi.co.uk founder, Dr Charlotte Inness, says that this handy appliance can make a home so much more pet-friendly. ‘They can help to absorb airborne dander before it settles, with some designed to blend into your decor as a stylish, functional ornament,’ she explains.

She adds, ‘Not only are these appliances beneficial during spring, but they make the home feel much cleaner and fresher for both you and your pets.’ Again, you’ll need to make sure that you use an air purifier with a HEPA filter - and pair it with one of the best vacuums for pet hair for maximum protection.

Will you be adding this handy appliance to your home?

If you already own an air purifier, you’ll know just how transformative these appliances can be. They spend their days quietly removing airborne nasties and keeping your home’s air quality steady amidst ever-changing pollen, dust, dander, and smoke levels. But have you ever wondered if you could get more out of your air purifier?

I’m a huge fan of the best air purifiers, and one thing I love is that they’re relatively hands-off. The smarter the appliance is, the less you need to get involved - and the more you can leave it to its own devices to work its magic and serve as one of the most important things people with healthy air quality always have.

However, a downside of this hands-off appliance is that we often forget about them, compromising their efficiency in the process. That’s why I asked air quality experts for their top tips on getting the most out of an air purifier - especially during these tricky spring and summer months. This is what they said.

1. Keep it on all day, every day

As we all do with electrical appliances in the home, you may worry about how much it costs to run an air purifier and turn it off periodically to combat rising energy bills. But if you want to make the most of your air purifier, you should keep it on all day, every day.

This is echoed by Lars Dunberger, Technology Development Manager for air purifier experts, Blueair. He says, ‘Our recommendation is to run your air purifier continuously to ensure efficient air circulation and low pollutant levels in your room.’

Of course, you don’t have to leave your air purifier on all the time if you don’t have any specific air quality issues. But if you’re using an air purifier to help with allergies, you live in a particularly busy city or want to combat rising dust levels in your home, it’s advised to keep it on for as long as possible. Ideally, all day and all night.

This ensures that the pollutant-busting appliance is working hard every minute to remove airborne nasties from your home and constantly releases fresh, healthy air for you and your family to breathe.

2. Position it perfectly

One of the things I wish I knew before buying an air purifier is that positioning is way more important than you’d think. And if you’re worried your air purifier isn’t working to its full potential, it may be time to rethink where you keep it.

Lars advises, ‘For optimal results, your air purifier should be placed in the room where you spend the most time, or where the air quality is the worst.’ This may be your bedroom, so that you can sleep better with hay fever, or near a window on hot days, where you have no option but to open it.

However, you also need to be mindful of the items you place around your air purifier. Johnny Liang, Air Purifier Specialist at Levoit, explains, ‘At the same time, avoid blocking the unit with furniture to ensure proper airflow. Good placement can significantly improve and stabilise overall purification performance.’

With this in mind, it’s well worth understanding how many air purifiers you need. And if you have multiple family members who would benefit from the purifying qualities of this appliance, it could work in your favour to buy one for the shared living spaces, and then buy more for each individual bedroom.

3. Keep up with maintenance

I will continually shout from the rooftops that air purifiers are worth it - but it’s fair to say that there is a caveat to this. That’s because an air purifier is only as good as the maintenance you give it, and to get more out of it in spring, you need to keep up with this.

Part of this maintenance is replacing the air purifier filter when necessary. And Lars explains, ‘Depending on the placement and how often you have your air purifier active, we would recommend changing the filter every 6-12 months for optimum efficiency.’

Most HEPA filter air purifiers (the most effective type) also come equipped with a pre-filter, which typically traps larger particles before they reach the main filter. These also require cleaning and maintenance, but can generally be vacuumed or wiped with a cloth.

It’s important to clean the pre-filter regularly, about once a week. Doing all of this will ensure it’s constantly working at optimal performance. And as Lars says, ‘Using a filter which is filled with dust or saturated with odours will not bring dangerous components to your home. But if the filter is full, it may be difficult for the clean air to come out, and it might damage the air purifier in the long run.’

Don't let your air quality get you down this spring. Make the most of these air purifier hacks instead!

Springtime is like a double-edged sword. On the one hand, the blossoming trees and green leaves are a welcome reprieve from the gloominess of winter. On the other hand, they’re a nightmare for those with allergies. And right now, pollen levels are extremely high.

Over the past few weeks, phrases like ‘pollen bombs’ and ‘red alerts’ have been making the rounds on the news and social media, with the Met Office issuing warnings to those who typically struggle with seasonal allergies. But what a lot of people don’t realise is that two of England’s most common trees are to blame for the high levels of pollen in the air right now.

Of course, there’s nothing you can do about the trees themselves - especially as tree pollen can travel huge distances from its point of origin - but there are ways to protect your family from an influx of airborne particles and pollen-proof your home. This is everything you need to know.

Tree pollen season explained

While pollen exists outside of the home, it’s incredibly easy for it to make its way indoors. Because of this, those who want to maintain a healthy air quality should keep track of seasonal changes. But as the Met Office will tell you, April is one of the worst months for tree pollen.

Writing on X on the 20th April 2026, the Met Office warned, ‘Here's a heads‑up for any hay fever sufferers struggling with tree pollen. Birch pollen levels are increasing to moderate or high for some, and oak pollen season is starting soon.’

Yes, while it’s easy to lump all pollen into the same category, the reality is that three different types of pollen affect hay fever - tree, grass and weed. And while we have grass and weed pollen to look forward to later in the year, it’s currently peak tree pollen season.

You can then split the tree pollen season down further, with the general timeline as follows:

• Early tree pollen season (January - February): Pollen is released by elm, willow, hazel, and alder trees.
• Peak tree pollen season (March - mid-May): Pollen is released by birch trees, which is one of the most potent pollens for hay fever sufferers. Ash and plane trees also release pollen.
• Late tree pollen season (mid-May - June): Oak, pine and plane trees release pollen during this time.

As birch and oak trees are among the most common in the UK, this is bad news for those with tree pollen allergies, which is a large portion of the population. In fact, an estimated 25% of people in the UK suffer from symptoms caused by silver birch tree pollen specifically, according to Allergy UK.

Sadly, just as tree pollen season winds down in mid-May, grass pollen season typically kicks into high gear. This offers even more opportunities for pollen to make its way into your home, whether through open windows, dirty shoes, drying washing outside, your pets, or simply clinging to your clothes.

This can then lead to prolonged hay fever symptoms and decreased indoor air quality, which is echoed by Lars Dunberger, Technology Development Manager for Blueair.

He says, ‘During tree pollen season, sensitivity can be increased in many people. This can cause a myriad of heightened effects to the individual, such as nasal congestion, a runny nose, frequent sneezing, itchy eyes and headaches. These effects can lead to disruption of sleep, increased tiredness and lack of focus at work or school, which impacts overall productivity.’

But that doesn’t mean that you can’t do something about it.

How to improve indoor air quality during tree pollen season

1. Use an air purifier

In my opinion, the best air purifiers are a must-have appliance for every household. After all, an air purifier is designed to filter out tiny airborne allergens - like pollen - from the air, releasing fresh air in its wake. This also means an air purifier can help with hay fever symptoms, but only if you choose the right one.

And as Lars explains, ‘One of the most effective pollen management strategies is to use a high-performing air purifier to remove pollen, dust and other small allergens in living spaces and bedrooms where you spend the most time.’

The top-rated model we’ve tested so far is the Blueair Blue Max 3250i Air Purifier (£169 at Argos), which offers dual filtration technology for spaces up to 48m2. There are other options available, but for pollen-busting properties, you’ll need one with a HEPA filter.

2. Close windows during peak pollen times

Just as pollen type varies throughout the year, pollen levels also fluctuate throughout the day. The pollen count is typically higher in the early morning and later in the evening, and while this isn’t guaranteed, it’s a good guideline for opening and closing windows.

This is especially true if you struggle to sleep with hay fever, as Molly Freshwater, Founder of Secret Linen Store, explains. She says, ‘When the temperatures begin to rise, and the sun is shining, the temptation to open your bedroom window and let in fresh air is understandable.

‘However, opening your window, especially in the morning, early evening and on windy days, can let pollen into your bedroom,’ she adds. As the aim is to keep as much pollen out of the house as possible, aim to keep them closed during peak pollen times.

3. Clean your home regularly

There are so many cleaning mistakes people with hay fever make, and not cleaning enough is the biggest one. That's because there are so many ways for pollen to enter your home, and pollen particles are largely invisible, too, which means you don’t know that they’re there.

With this in mind, one of the best ways to combat rising tree pollen levels is to clean more than you’d think - using one of the best vacuum cleaners with a HEPA filter to capture pollen particles that get stuck within the fibres of your carpets and rugs.

Personally, I also swear by the Scrub Daddy Damp Duster (was £4.49, now £2.98 at Amazon) when dusting during peak pollen season, as the ridged, damp cleaning tool traps tiny particles instead of just pushing them around.

4. Clean yourself regularly

If you want to keep tree pollen to a minimum in your home, you also need to target the things bringing the pollen into your home, which, most of the time, is you. That’s why you should also clean yourself regularly if you struggle during this period.

Lars advises, ‘Take regular showers, changing clothes and washing sheets in hot water to remove any pollen taken in from outside into the home.’ It’s also a good idea to remove shoes before entering the house, and, ideally, you should also avoid drying any clothes or bedding outside during peak pollen times.

If you want to go one step further, you could also use an allergy-friendly laundry detergent like this Ecover Zero Non-Bio Laundry Detergent (was £10, now £6.98 at Amazon) to keep any other potential allergens at bay.

Tree pollen season may be here, but you don't have to let it take over your home!

Dust, pollen, smoke, and pet dander are among the most common airborne pollutants found in UK houses. And while you can’t see them, they can drastically reduce your home’s air quality if they’re not dealt with. But, thankfully, that’s easier to do than you’d think.

Yes, the idea of improving your home's air quality may seem daunting, but there are quick fixes and affordable products you can buy to create a healthy space for you and your family. This can help those who struggle with hay fever, breathing difficulties, or just want to know that their safe space is as safe as it can be.

So, I’ve put together a list of the things that people with healthy air quality have in their homes, inspired by the pollutant-busters I use in my own house - as well as the things I know my air-conscious friends, family and colleagues use on a daily basis.

1. An air purifier

The easiest way to improve your air quality without actually doing anything is to invest in one of the best air purifiers. After all, this handy appliance is literally designed to capture nasty airborne pollutants in your home and push clean, fresh air back out.

And while there are so many different types of air purifiers out there, those who truly value their air quality should choose one with a true HEPA filter that captures 99.7% of particles. This will ensure that it can successfully help with hay fever and even reduce the dust build-up in your home.

It’s important to note that every air purifier is different, though, and some are suited to smaller rooms while others can tackle larger ones. To help you choose an air purifier, it’s a good idea to understand the size of the space you want to purify so you’re not let down by the results.

2. A damp duster

One thing I will continue to shout from the rooftops is that damp dusting is always better than dry dusting - especially if you want to improve your home’s air quality. That’s because dry dusting just doesn’t cut the mustard, often either pushing dust around or wafting it into the air to settle elsewhere.

Damp dusting is an affordable alternative to dry dusting that actually captures dust while you’re cleaning and prevents the particles from becoming airborne - meaning it’s even easier to get rid of dust altogether. And while you could simply dampen a microfibre cloth and wet dust that way, I swear by the Scrub Daddy Damp Duster, £4.49 at Amazon.

As this damp duster has ridges carved into it, it’s even more effective at capturing dust - and then all you have to do is rinse it under the tap to clean it off and continue dusting. There are also own-brand alternatives that are at a similar price point, so they’re not hard to find.

3. Plants

Often, improving your air quality involves appliances that don’t add anything to your home’s decor or style - but that’s not always the case. After all, those who want healthy air quality can also make the most of the best air-purifying indoor plants that also add greenery to your home. Thompson & Morgan has a handy air-purifying house plant collection, available from £19.99.

There are so many houseplants that can reduce dust, and combining these will ensure that your plants are working hard to reduce many of the airborne pollutants that affect your home’s air quality. Of course, they’ll take significantly longer than an air purifier to do so, but they can still be effective.

In fact, snake plants (you can find a selection of different snake plant varieties for £12 at B&Q) have been proven to remove toxins like carbon monoxide and formaldehyde from the air, and aloe vera (£12.99 at Thompson & Morgan) can remove benzene, which is found in countless supermarket-bought detergents and cleaning products. And while they’re doing this, they’ll continually add more oxygen to your home, too.

4. A HEPA vacuum

As Ideal Home’s Certified Expert in Vacuums, I’d like to think that I know a thing or two about the best vacuum cleaners - but one thing I don’t think enough people know is that vacuum cleaners can spread dust. Especially if you’re using the wrong one.

And if you want to keep nasty pollutants out of your home, it’s best to choose a vacuum with a HEPA filter that will help to capture them and prevent them from leaking back into the house. Models with HEPA filters are typically more advanced models, too, so they will offer better suction power and technology to remove any lingering dust, dander, or pollen embedded into carpets and upholstery - especially if you try 'slow vacuuming.'

Of course, the bagged vs bagless vacuum cleaner debate is also key when thinking about household air quality, as bagged models are typically safer and healthier than those that require emptying into the bin, as they seal the contents inside.

5. A decluttering schedule

While dust, pollen and smoke are among the most common airborne pollutants in homes, damp and mould can also affect those with allergies, and particularly those with breathing difficulties. And while air purifiers can help with damp in the sense that they can capture mould spores and stop the problem from getting worse, they’re not the only things you can use.

Naturally, the best dehumidifiers are ideal for moisture-prone homes, but those who want healthy air quality should also maintain a regular decluttering schedule. There are even certain items that you should always declutter to prevent damp, as failing to do so can trap dust, moisture and mould spores.

Decluttering also allows you to damp dust more regularly and maintain a steady air flow throughout your home, which will improve the effectiveness of your air purifier and help you breathe easier. This is completely free to do, but I’d suggest investing in clever storage to help you out.

How will you be improving your air quality this year?

I believe it’s fair to say that ever since the pandemic, we’ve all been a little more conscious of the quality of the air we breathe at home. So if monitoring the air quality of your home is something that you’re interested in, IKEA has a handy new smart gadget: The ALPSTUGA Air Quality Sensor (£25).

While it’s becoming increasingly common to spot one of the best air purifiers inside the home (and for good reason, especially during winter), a smart sensor such as IKEA’s will help it work to the best of its ability to make your home a healthier and more comfortable place to live.

Providing you with an easy way to check your home’s air quality, it’s no surprise that the ALPSTUGA Air Quality Sensor is already selling out fast. Here’s everything you need to know about how it works.

The ALPSTUGA Air Quality Sensor is designed to pair with other IKEA air purifiers. However, it is compatible with any air purifier that is Matter-compatible, meaning it should integrate with most smart home ecosystems.

This alone makes it a great deal in our book. The sensor has real-time monitoring, tracking the humidity, temperature and volatile organic compounds. It will indicate when the air quality in your home is poor, so you can switch on your air purifier to improve the air quality of that room.

IKEA recommends placing the sensor in areas of the home that you spend the most time in, such as bedrooms or living rooms. You can also set the display to a clock, making the device blend as a seamless piece of your home’s decor.

However, this IKEA air quality sensor keeps going in and out of stock online, with limited availability in stores, so you’ll have to act fast if you want to get your hands on one. Alternatively, B&Q’s Airthings Wave Mini Smart Air Quality Monitor (£68) is a suitable alternative.

Connected to an app on your phone, it checks your air quality levels, local pollen levels, humidity, volatile organic compounds and even your risk of mould. It’s cable-free, uses batteries, and has a 5-year warranty, too. Plus, it’s well-reviewed, too.

‘This little device gives some useful information and is great to check the TVOC, humidity and temperature anywhere in your home. It gives daily, 48-hour average, week, month and year data with its Bluetooth phone app. I will be buying more of these for other areas of the house and will be buying the larger unit to monitor even more items,’ said buyer.

‘What a neat little device! I love how it connects to your smartphone and gives you readings of the air quality in your home from anywhere! Truly advanced technology at its finest! Highly recommended!’ said another.

Here are a few more air quality sensors I’ve found that are well-reviewed.

Checking the air quality of your home is important, especially during cold and flu season, as a way to keep your home healthy and safe. IKEA is proving that this can be achieved on a budget.

If I’m being totally honest, I’ve been struggling with the darker, colder mornings. I wake up feeling groggy and tired, and often feel bunged up as a result of the many germs making the rounds right now. But I’ve just got my hands on the Blueair Mini Restful Sunrise Alarm Clock Air Purifier (£169 at Amazon), and I can already tell that it’s going to make my mornings brighter.

Of course, as Ideal Home’s air quality expert, I’m no stranger to the best air purifiers. It’s quite literally my job to test new models each month, and I’ve always got at least one air purifier working its magic to remove airborne pollutants from my house. But Blueair’s new model isn’t your average air purifier; it also doubles up as a sunrise alarm clock to support healthier habits and improve your winter wellness.

For the past couple of days, I’ve been waking up to a sleek design, gradual sunrise light, and soothing soundscape - and not to mention healthier, more breathable air in my bedroom. Plus, I’ve already experienced a noticeable difference in my morning routine.

Similar to a SAD alarm clock, the Blueair Mini Restful Sunrise Alarm Clock Air Purifier is designed specifically for bedrooms - and this particular model, which is part of the brand’s new Sleep Collection, is suitable for rooms up to 13 m². And while it offers a simple Scandi-inspired design, the effects are impressive.

Thanks to the gradual sunrise that gets brighter 15-30 minutes before your alarm and the customisable soundscapes, you can wake gently and naturally with the sun, which isn’t always present during the autumn and winter months. This helps to balance your circadian rhythm, which often goes out of whack when the seasons change.

As I’ve always found it particularly difficult to get up in the mornings (and I’ve currently got the lurgy that everyone seems to have), I like that the app allows me to customise my wake-up. So, I’ve opted for a 30-minute sunrise, and the happy chirping of birds as my alarm soundscape.

I also keep the air purifier on all night to combat dust and germs, and as a light sleeper, I was over the moon to hear - well, not hear - that the 18dB noise level is virtually silent.

Its Quiet Mark certification is impressive given its credentials, too. The air purifier aspect of the Blueair Mini Restful Sunrise Alarm Clock Air Purifier can capture up to 99.97% of airborne pollutants down to 0.1 microns, whereas many other air purifiers can only do so down to 0.3 microns.

The aim is to help customers sleep better and prevent wake-ups through the night, which are often caused by seasonal germs, sore throats, coughing fits, or sneezing due to dry air from central heating systems.

However, I need to note that the Blueair Mini Restful isn’t as high-tech as other air purifiers out there - especially other Blueair air purifiers, which have consistently landed themselves at the top of our best air purifiers guide.

Unlike standalone air purifiers that continuously monitor your air quality and provide regular PM readings, the Mini Restful doesn’t do that. It also doesn’t have an ‘Auto’ mode that adjusts the fan speed based on your home’s air quality. Instead, it’ll just run in the background for as long as you need it to, but you can adjust the fan speed setting yourself if you want to.

For the everyday user who just wants to breathe easier during the drier winter nights, this should still be more than enough - especially if you don’t already have an air purifier in your bedroom.

But if you have specific breathing difficulties and really want to monitor your air quality, I’d suggest opting for a separate sunrise alarm clock and air purifier with more features and a built-in sensor.

Alternatively, you could opt for another product within Blueair’s new Sleep Collection - the DreamWell Room Humidifier (£169 at Amazon), which uses an invisible mist to clear sinuses, tackle dry skin and create a soothing environment for restorative sleep.

Talking about this collection, Andy Lu, CEO of Blueair, says, ‘We’ve spent decades pioneering air wellness, and the Sleep Collection is a natural evolution of that mission. By combining our trusted purification and humidification technologies with thoughtful design solutions built specifically for the bedroom, we’re helping people not only breathe healthier air, but also wake up feeling more rested and restored.’

And so far, I have to say that I’ve been impressed!

Winter sleep essentials

If the Blueair Mini Restful doesn't quite float your boat, there are many other products to help you wake up when it's still dark. These are some of my favourites.

With this new sunrise alarm clock air purifier in tow, I know it's going to be so much easier to wake up in the dark this winter.

There’s no denying that mornings are getting colder, nights are getting darker, and the leaves are already starting to fall. And while it’s not quite time to turn the heating on just yet, many people will be getting ready to open up their fireplaces or fire up their wood burners this month. If you’re one of them, experts warn you to do one thing before you do that.

Of course, the best fireplace ideas offer so much more than that cosy, autumnal aesthetic. They also help you keep your home warm without needing to turn on the heating, especially before winter really sets in. However, it’s important to realise that burning anything in an open fire isn’t conducive to a healthy home environment.

Fires let off smoke, carbon monoxide, VOCs and tiny particulate matter that reduces the air quality in your home, which is particularly dangerous if anyone in your family already suffers from any health concerns. So, what do you need to do? Well, experts want you to invest in one of the best air purifiers to keep your home (and your family) healthy.

Why you should use an air purifier with a fireplace

It’s more important than ever for us to take active steps to improve air quality at home, and the reality is that burning anything in our homes is counterintuitive to that.

As Lars Dunberger, Head of Technology at Blueair, explains, ‘Tiny particles from wood burners and open fires permeate into the room. This fine particulate matter (PM2.5) is so tiny it can penetrate the lungs, move into the bloodstream, and cause respiratory difficulties, heart and lung problems and a host of other diseases. Using an air purifier can help reduce these particles quietly and efficiently.’

Emily Blance, a Design Engineer at Dyson, also adds, ‘Burning fuels such as wood, gas or oil can release VOCs, which are emitted during combustion.’

And while wood burners are generally considered healthier in the wood burner vs. open fire debate, as the smoke is pushed directly out of the flue pipe, some harmful particulates can still make their way into your home, and cleaning it can expose you to them as well.

Of course, there are alternative fuel options on the market and smokeless fuels - like these MDL Instant Light Smokeless Fire Logs (£21.99 at Amazon) - that give off around 80% less smoke than ordinary logs, but there’s still that 20% lingering in your home and potentially causing you harm.

However, it’s unrealistic to ask everyone to stop using their fireplaces and wood-burning stoves, and it's more practical to make the most of air purifiers instead. After all, air purifiers help with allergies, which are also caused by these tiny, airborne particles.

And as these particles are so small, they’re invisible to the naked eye, making them even more dangerous. That’s why using an air purifier - which pulls in polluted air, filters out the nasty particles caused by burning fuels in the house, and then releases fresh, clean air - in tandem with your fireplace or wood burner is a must-have. The same can be said when you burn candles in your home, too.

Lars adds, ‘Using an air purifier not only reduces smoke exposure but also helps clear everyday indoor pollutants such as dust, cooking odours, scented candles, and chemicals from cleaning products. It even removes bacteria and viruses, lowering the risk of coughs and colds. By placing an air purifier in the rooms you spend the most time in, you can enjoy your fireplace safely while keeping the air in your home cleaner, healthier, and safer for everyone.’

It’s important to note that you can’t just buy any air purifier, though. It’s essential to select the right air purifier for your specific needs, particularly in cases where the harmful pollutants are caused by open fires.

How to choose an air purifier for homes with fireplaces

While there are so many different air purifiers out there, they’re not all the same. Some are more powerful than others, and if you plan on using an air purifier with a fireplace this year, it’s important to opt for one that’s powerful enough to deal with the onslaught of pollutants caused by burning fuel.

Lars advises, ‘Choose a purifier with a high Clean Air Delivery Rate (CADR) for efficient air cleaning. Opt for a carbon filter in addition to a particle filter for homes with wood burners, as this will trap and remove smoke particles.’ He also suggests running the air purifier continuously to ‘maintain low pollutant levels and effective air circulation.’

As someone who has tested countless air purifiers, I’d also suggest opting for one that has an ‘Auto’ function. So, it’ll automatically sense any reductions in the air quality (for example, when you initially fire up your fire) and boost the power to successfully remove the extra pollutants. Then, it’ll only reduce its power when it senses the air quality has increased to a healthy level again.

It’s also important to maintain your air purifier, too. Lars says, ‘Regularly check and clean the pre-filter if your model has one. Replace the main filter when the air purifier indicates it’s time to ensure optimal performance.’

So, based on all of the above, these are the 3 air purifiers I’d recommend using if you’re opening up your fireplace this month.

FAQs

Are air purifiers good for log burners?

Yes, absolutely! If you have a log burner in your home and regularly light it, it's well worth using an air purifier alongside it. This will reduce the amount of harmful pollutants lingering in your home and causing any potential health concerns.

This will lead to cleaner air and improved air quality, and it can even help with the lingering smell of smoke you may notice after using your log burner.

How to clean the air in your home from smoke?

Ventilation is key if you want to clean the air in your home from smoke, so regularly opening windows, using extractor fans, and keeping chimney flues unblocked is essential. However, it's not always possible to open windows during winter months, which is where air purifiers can help.

Air purifiers will circulate the air in your home, filtering out the smoke and other harmful pollutants from the air, and then releasing clean air back into your house.

Cleaning regularly will also help you keep your home clean from smoke, and keeping on top of dusting and vacuuming will remove lingering soot that can often cause such smells.

So, if you're opening up your fireplace this month, make sure you start using your air purifier, too!

The Vortex Air Cleanse, RRP £179.99, is a fan and air purifier hybrid. This means when switched on, the air it’s fanning you with has been forced through a filter to remove airborne nasties such as pollution, pet dander and other allergens. As well as blowing air out, it can warm the air too on the heat settings, meaning you can use it in cooler months too.

Like many of the best air purifiers, the Vortex Air Cleanse has various settings, such as fan speeds and a sleep function, so you can leave it on while you sleep, and it will automatically switch off. It’s also pretty quiet, even on the highest setting while oscillating – which it can do through 70 degrees.

I am an experienced product reviewer and have tested almost everything but kitchen sinks at this point (but I have done boiling-water taps!). When testing, I’m always looking at the quality of a product versus functionality and price, and it was no different when I tested the Vortex Air Cleanse fan. I set up the fan in my four-bedroom house and moved it between rooms to see how it performed in different room settings. Close attention was paid to elements such as energy efficiency, noise, cooling capabilities and how easy it was to operate.

In a nutshell

A decent fan that offers air purification and heating as well as cooling functionality. While not quite as mighty as the Dyson hot+cool, it’s a lot cheaper, too. I rated it for its cooling capabilities and its energy efficiency.

How I tested

Unboxing and setting up

The Vortex came in a brown cardboard box. I was able to carry it upstairs without too much effort, so it’s relatively lightweight. Inside it was encased in styrofoam, and then everything was inside plastic packaging too.

This was a shame from an eco point of view, as styrofoam is hard to recycle for many of us, as it’s not normally accepted in roadside collections. The quality of the packaging didn’t blow me away, but the fan itself looked smart. On reading the instructions, there are quite a lot of spelling errors in them, which admittedly doesn’t fill me with confidence.

Design

The Vortex Air Cleanse is pretty silent, so great for when you’re working or sleeping or watching TV. It’s also an air purifier, so allergy sufferers in particular will hopefully see the benefit of this.

It looks very similar to the Dyson hot+cool (which I’ve also had hands-on experience with), but it’s a good bit cheaper, so bargain hunters will love it. And because it’s blade-free, the Vortex is great for families and pet owners too.

Performance

I found the Vortex Air Cleanse easy to use. Plug it in, press the button on the unit, and you can then control it using the remote or the buttons on the unit. The buttons on the unit are silver on a white background, so if you have a visual impairment, these might be hard to see. On the remote, I found these weren’t as initiative as I’d have liked with the time and speed functions – there are instructions to explain what each button does though.

Personally, I always like having a long flex on electricals – it allows me to be flexible on where I place devices around the room. On the Vortex, I would have liked the flex to be a bit longer, as I want to have the fan close to the foot of my bed in summer. You can, of course, use an extension cable if needs be.

Air purification

Vortex claims ‘the advanced H13 HEPA filtration system captures 99.97% of airborne contaminants, including allergens, mould spores, dust and bacteria.’ On many air purifiers, you can see the air quality through smart features and an app on your phone. The Vortex doesn’t offer this functionality. You just have to trust it’s cleaning the air.

Robust hot and cold air

Vortex is designed for both cooling air and warm air. I was really impressed by the performance of this bladeless fan. It cooled the air around it effectively, even on a lower fan speed (there are 10). I noticed cooler air immediately when the cool function. I also tested the warm air, and this was just as good, blasting warm air immediately around my large bedroom.

Smooth, 70-degree oscillation

I have suffered the groaning churn of a tired fan as it oscillates to cool the whole room, but that wasn’t the case with the Vortex. It was absolutely silent as it turned 70 degrees. I found the oscillation range more than enough to cool a large bedroom.

Timing function

You can set the Vortex to turn off after a set number of hours. The number of hours is displayed on the small LED screen on the base of the fan, so you know what you’ve selected. You can set it to be on for 1-9 hours, so you can decide how long to have it on while you sleep. This is a handy feature that allowed me to sleep soundly knowing the fan would eventually switch off.

Noise levels

The Vortex claims to offer ultra-quiet functionality, and that’s definitely something I noticed during testing. It’s very quiet, even at the highest fan speed.

At 10, it is no louder than the rain outside your window, and the white noise is actually quite soothing - especially if you’re going to sleep. I could easily have it next to me and watch TV or participate in a Teams call without the fan distracting me.

Cleaning and maintenance

I was sent a sample in white, but the Vortex Air Cleanse comes in eight different colourways – some are going to hide the dust better than others. The white version was easy to keep clean – it’s fairly smooth with no blades, so a quick wipe down with the duster was all it took.

The fan draws in air through the base and filters it here before blasting it out of the oval at the top. This means the filters in the base need to be replaced every 3-6 months – they can’t be cleaned. These are £17.99 on the Vortex website plus £1.99 shipping at the time of writing.

Energy use

At 34w for cooling, this fan costs as little as 9p to run for nine hours. However, when heating this goes up to 1,950W, which would set you back £4.75 for nine hours – you might find more efficient ways to heat your space.

How does it rate online?

Allergy sufferers seem to really rate the Vortex Air Cleanse, saying it eased the symptoms of their allergies considerably. Others have noted that there’s no real way to tell if the air purification is working.

A few people are pointing out that you can’t have air purification on without the fan working. Like me, many people are impressed with how quiet the fan is during operation.

How does it compare to similar models and its predecessors?

As I mentioned above, I’ve tested the Dyson Hot+Cool Gen1, RRP £549.99, before, which is very similar to the Vortex Air Cleanse in that they both heat, cool and purify air. The Vortex is more lightweight in a few ways, though: cost, functionality and literal weight.

The Dyson actively shows how much “bad stuff” it’s cleaning out of the air, which offers reassurance – and yes, a certain degree of smugness. However, it’s £550, which I am not convinced is worth it to feel smug. The Vortex is also perhaps a little less robust, yet they both weigh around the same amount. This doesn’t bother me, but if you have kids kicking footballs around the house or a dog who gets the zoomies, you might feel a bit on edge with them being around the Vortex.

On the other end of the spectrum, I have a Dimplex DXMBCF Mont Blanc Cooling Fan, £84.99. This offers just fan capabilities and is slightly cheaper than the Vortex. It’s probably on par with the power of the Vortex, but it doesn’t come close to the quality of the build, and nor does it offer heating or air purification.

Should you buy the Vortex Air Cleanse?

I would recommend the Vortex Air Cleanse as a purchase if you want the dual functionality of air purification and cooling/heating the air, too. It’s a great, energy-efficient fan that’s really reasonably priced.

For way too long, air purifiers have been boring, white eyesores that add absolutely nothing to your home decor. But in an attempt to help you show off your air purifier (rather than hide it away), Shark has launched a smaller version of their bestselling air purifier in a range of pastel colourways - the Shark NeverChange5 Compact Pro models (£149.99 at Shark) - and it's safe to say that I'm a little bit obsessed.

While the Shark NeverChange5 has already made its way into our best air purifiers guide, these new models are smaller and more compact - perfect for desktops, bedside tables, nurseries or even uni halls. The fact that they come in three new amazing colourways is also the cherry on top of the cake, and this is everything you need to know about them.

These new releases are particularly exciting for me, as the Shark NeverChange5 is the air purifier I use in my own home, having done so since it impressed me so much during testing. And while the recommended room size of the Compact Pro is (obviously) a bit smaller - 23m² compared to the larger model’s 60m² - this is still more than enough for the average UK living room, bedroom or office.

But as the model I use at home is white and fairly unassuming, I have my eyes on brightening up my space with these new colourways - and just know how good the mint will match with my green sofa bed and wardrobe in my home office.

However, the quartz and the lavender are close seconds, and I can't help but wonder whether I should just buy all three. After all, each colourway brings something different to the table...

It seems as though this is something Shark is focusing its attention on at the moment. Not only have we seen similar colourways in their viral Shark FlexBreeze HydroGo, but the same colourways can be found within their Shark VacMop vacuum and mop combo, too. And as I own both of these things (yes, you could say that I am somewhat of a Shark superfan), I’m excited to add another bright appliance to my collection.

But that’s not all, as the geniuses at SharkNinja HQ have also given the bestselling Ninja Slushi a pastel makeover, too. So, it’s clear to see that they’re not afraid to go bolder and brighter with their designs.

However, this new air purifier offers so much more than just its looks. It’s also equipped to capture up to 99.97% of allergens in your home (which is ideal if you want to pollen-proof your home or you live by a particularly busy road or in a big city), offers CleanSense IQ technology to detect air quality changes before you do, and it even comes with Anti-Odour Capsules that release a fresh scent while it’s cleaning your air.

But the pièce de résistance of the NeverChange5 - and why it’s been given its name - is that you won’t need to replace the filter of your air purifier for a whopping five years. And considering some other models and competitors require bi-annual filter changes, this will save you a lot of money in the long run. Up to £200 of savings, according to Shark, actually.

However, if the new pastel colours don’t quite tickle your pickle and you want to opt for something a little more unassuming, Shark has also released the Compact Pro in a dove-white colourway instead. And it’s currently on sale!

I'm definitely here for Shark's new brighter, bolder look... are you?!

Like many homes, mine struggles with poor ventilation - morning condensation, the off patch of (albeit well-maintained) damp and an ever-growing pile of laundry that takes forever to dry, especially without a proper working utility area due to building works. So I was more than happy to put the Dryzone dehumidifier and air purifier to the test.

With renovation work in full swing, I knew I needed something that could tackle excess moisture in multiple areas, help prevent mould as things dry out and speed up drying times for our family's insane amount of laundry.

With the knowledge that the best dehumidifiers will lower humidity levels, prevent damp and speed up laundry drying times, I was thrilled that the Dryzone has delivered on all three. And combining that with air purifying capabilities and this little bad boy is well worth its small price tag.

This compact unit combines dehumidifying power with a built-in medical-grade HEPA filter to improve air quality too. I tested it using our standard dehumidifier testing process to see how well it performs, not just in reducing humidity, but also in how easy it is to use day to day.

At a glance

As the name suggests, the Dryzone dehumidifier and air purifier is a compact, dual-function device designed to reduce moisture in the air and filter out particles like dust, allergens and pet dander in rooms up to 15m2.

It features a 1-litre water tank and has the ability to extract 12 litres of moisture a day, with an auto-shut off function that kicks in when the tank is full, which is a handy feature if you're running it overnight or while out of the house.

Speaking of overnight use, while testing, I found it to be impressively quiet, producing a lower hum so it was just like white noise, which I can definitely sleep through. Energy usage is low so it's an affordable option to run longer-term if you're tackling a particularly tricky space. It's also lightweight, so it's easy to move around. However, it would be even better if it had a carry handle instead of little built-in areas to handle it by.

However, don't let its small stature deceive you because it's actually pretty powerful. It managed to dry t-shirts in a couple of hours, and it reduced the humidity in the room from 60% to 50% in four hours.

It doesn't have WiFi connectivity or hands-free controls that others have on the market, but you could sacrifice that for its performance and budget-friendly price tag.

Unboxing, set-up and design

Unboxing the Dryzone dehumidifier and air purifier was refreshingly straightforward. It arrived well-packaged in a compact box that had minimal plastic and no unnecessary fiddly bits to take apart.

Inside, you'll find the unit itself, a user manual, and the washable filter attached that needs to be slotted into place (this was very intuitive). It's pretty much plug-in-and-go.

The design itself is neat and unobtrusive, and it fits into any room perfectly without being really in-your-face. The controls are located on the top panel and clearly labelled, so it's pretty easy to get to grips with what's what.

The icons on the LED display are intuitive too, with the air purifying function a leaf, the laundry mode a t-shirt, the sleep mode a moon and the fan functions, well, fan icons.

First impressions? I loved that it didn't need any syncing, apps or complicated settings. All I needed to do was have a quick scan of the user manual, and I had it up and running in no time. I think for a budget-friendly machine, it feels well-built in its simplicity.

Ease of use

When I tested it for laundry-drying, I was pleasantly surprised by how much of a difference it made. I kept it beside my clothes airer and had a relatively small load hanging up. The T-shirts that were hanging up dried within two hours, which is impressive for a compact dehumidifier.

For bulkier items like shirts and trousers, they dried a few hours later, but overall, it made a noticeable difference to the drying process compared to just air-drying. It's especially handy if, like me, you're short on space and have to dry laundry hanging in the bedroom or hallway.

I also used the unit in my daughter's newly painted bedroom, and it worked really well for clearing that heavy, lingering paint smell and the extra humidity that often comes with decorating and building work.

Within a few hours, the room felt noticeably less stuffy, and the overpowering just-painted smell that lingers for days was definitely reduced. The air purifier function seemed to make a real difference in circulating the air. It made the space feel more comfortable much sooner, which made a big difference when I was trying to get it ready for her to sleep in it again.

Performance

Overall, I was really pleased with how the Dryzone dehumidifier and air purifier performed. I live in a Victorian house with original single-glazed windows, so condensation and damp are part of daily life, especially in the colder months. I rely on dehumidifiers to keep the air dry and prevent mould, and the Dryzone made a noticeable difference.

We're also mid-renovation and recently plastered and painted my daughter's bedroom. I'd noticed the air still felt damp in there weeks later, so I rolled in the Dryzone overnight. The digital humidity display made it easy to track the changes.

In the bedroom, the humidity dropped from 60% to 50% in under four hours, which felt like a solid result to me. With ideal indoor humidity levels typically between 30 - 50% in winter and 40 - 60% in summer, I was happy with how quickly it reached a comfortable level.

Right now, with the house still in a bit of chaos, I haven't used the continuous drainage hose, but once our utility room is up and running, I'll set it up in there so it can run uninterrupted.

Energy use

If you're curious about how much a dehumidifier costs to run, it largely depends on its wattage. The higher the wattage is, the more energy it uses.

With the current energy price cap at 24.5p per kWh, I've calculated that it costs around 4p per hour to operate the Dryzone on the highest setting. That's impressively low, especially for a unit of this capacity and compared to other dehumidifiers like it.

So, you can comfortably run it for hours, whether you're drying laundry or reducing damp, without worrying about it impacting your electricity bill.

Noise levels

Operating at just 36dB to 38dB, depending on the fan setting, the Dryzone is actually pretty quiet compared to others on the market. On its lowest setting, the sound is barely noticeable, while on its highest setting, it's still acceptable, producing a not-too-annoying whoosh noise.

Obviously, with its specifically designed sleep mode, it's even quieter because of its reduced fan speed, making it ideal for bedrooms and even kids' rooms (no white noise machine required).

The noise ramps up for laundry mode, though, because it's working faster to get rid of moisture. Saying that, even in this setting, it's not antisocial.

Portability

One of the things I really liked about the Dryzone dehumidifier and air purifier is how easy it is to move about. It's fitted with smooth gliding castor wheels, which are easy to get over carpet and recessed carry-handles, so I could roll or lift it from room to room without much effort.

It's slim and compact, so it didn't take up too much space either, so I feel like I can use it in pretty much any space.

Maintenance

Looking after the unit is relatively straightforward and doesn't require much effort. The water tank is easy to remove, but without a built-in handle, it’s a little bit tricky to empty, because the tank is small, and it’s lightweight enough to carry. I have been giving it a rinse with warm water to keep things fresh, especially after heavy use.

According to the manual, this HEPA filter should be cleaned every two weeks, which I found easy enough to quickly wipe down with a dry cloth, or a vacuum if it's more heavily soiled. It's also worth giving the interior where the HEPA filter is inserted a quick wipe too with a soft, dry cloth.

When the filter becomes too worn or clogged over time, replacement filters are available to buy directly from Safeguard Europe's site.

How does the Dryzone Dehumidifier and Air Purifiers rate online?

The Dryzone Dehumidifier and Air Purifier garners consistently strong ratings across a number of retailers.

Verified shoppers on Amazon rated it 4 out of 5 stars, citing its low-noise operation, ease of use and noticeable improvements in air quality and damp control. One reviewer on Amazon noted the HEPA filter's effectiveness at capturing dust and allergens, while another reported that indoor laundry dried quickly when using the machine's laundry mode.

There are a lot of reviews noting how quiet the unit is, plus its portability and reliability, making it a strong performer for family homes dealing with damp and condensation, as well as drying copious laundry loads.

Verdict

If you're after a fuss-free dehumidifier that also freshens the air in your home, the Dryzone is well worth a look. It's neat, easy to use, quiet enough to run overnight, and makes a noticeable difference to indoor humidity levels.

OK, it might not replace a full-size HEPA air purifier, but for the price, you're getting great value in a little package. Its intuitive settings and energy efficiency make it a great choice for busy family households with limited space to play with.

At £149.99, it's a great price for a 2-in-1 unit, and compared to the similarly priced ProBreeze 12L Dehumidifier with Built-in Humidistat, the Dryzone gives it a run for its money. Although the ProBreeze has a larger water tank, so can be used in larger rooms.

Compared to competitors, like the SmartAir Dry Zone dehumidifier, the Dryzone wins out on portability and simplicity. Plus, it's lighter, quieter and has zero digital fuss.

Blueair has already made a name for itself in the air purifier world, with many of its models topping the charts in our best air purifiers guide. And while we're big fans of the Blue Max 3250i at Ideal Home, awarding it a well-earned top position, it's now a little old.

So when the Swedish clean air brand launched the Blue Pure 511i Max – a new and updated version of our top-rated budget pick, the Blue Pure 511 – I was keen to put it to the test. After using it for the past two weeks, I think it's a solid all-rounder, and for an affordable price, too.

In a nutshell

The Blueair Blue Pure 511i Max is a stylish, lightweight air purifier that delivers great all-around performance for everyday use. It’s simple to set up, easy to use (thanks to the intuitive controls and app connectivity), and runs quietly enough on low settings that you’ll barely notice it’s there.

I've been testing this air purifier for two weeks now, and there's no denying that it does the job. It wasn't the quickest to register the dip in air quality during our smoke and cooking tests, but it made up for this when tackling VOCs in the deodorant test. Somewhat sadly, it didn’t register dust at all during testing, but this felt like a minor drawback in relation to the bigger picture.

Maintenance is easy, too. The pre-filter is machine washable, the main filter is simple to replace (with a handy reminder light), and at under 1p an hour to run, it’s energy-efficient enough for continuous use.

It's fair to say that I'm a fan of the Blueair Blue Pure 511i Max. If you’re looking for a quiet, effective purifier that doesn’t overcomplicate things, the 511i Max is a solid choice, and I'll certainly continue to use it in my home going forward.

How I tested

Unboxing and setting up

The Blueair Blue Pure 511i Max Air Purifier arrived in a lightweight box that was easy enough to carry solo from room to room. The box itself had a clean, minimalist design which neatly reflects the brand’s overall look and messaging.

Inside, the purifier was wrapped in sheets of single-use plastic, as was the user manual – something I found disappointing given Blueair’s focus on clean living. I’d have preferred to see more eco-conscious packaging materials used throughout.

Setting the device up was simple enough. I plugged it in, pressed the power button on the control panel, and the purifier switched on without issue. To make the most of its features, I downloaded the Blueair app by searching for it directly in my app store. While the user manual includes a QR code, this (strangely) didn’t work for me.

Once I had the app, it took just a few minutes to connect the device, create an account and pair it with my WiFi. From there, the purifier was ready to use.

Design

Having tested the Blueair Blue Pure Mini Max already, I knew what to expect when it came to the design of the 511i Max. The biggest difference between the two models is (literally) the size – the 511i Max stands at 48cm tall, compared to the much smaller 29cm height of the Mini. While this newer model is certainly larger, it still feels compact enough to fit comfortably into most living spaces without dominating the room.

Like the other models in the Blue Pure range, this air purifier comes with a removable fabric knit cover, which is available in two colourways. The standard option is Stockholm Fog, a simple, neutral grey that won’t clash with most home decor styles. If you prefer something with warmer tones, there’s also the Limestone Beige option, which can be bought separately for £15.

The user interface is clean and minimal, with clearly labelled buttons for power and fan speed, plus indicator lights for the device’s different modes. These include Auto, Night, and fan speeds 1, 2, and 3. There’s also a small WiFi icon that lights up when the device is connected, along with a filter replacement indicator.

On the front of the purifier is an LED air quality status light, which changes colour in line with the room's air quality: blue for excellent, green for very good, yellow for moderate, orange for polluted, and red for very polluted.

Overall, I quite like how the Blue Pure 511i Max looks in my home. There's something simple and minimalist about it which – aside from aligning with my personal decor style – feels very appropriate for an air quality device.

Performance

When we test air purifiers at Ideal Home, we prefer to judge them based on how they function in real-life home settings. To do this, we perform a series of tests that really put these devices through their paces, allowing us to paint an accurate picture of how they perform.

The Blueair Blue Pure 511i Max certainly looks the part and boasts some impressive-sounding features, but I was keen to see how well it lived up to its expectations. To gather a more detailed overview of how the device performed, I referred to the Blueair app consistently during testing. This offers a breakdown of current PM2.5 levels, which includes fine particles like dust, bacteria, and pet dander – the ones small enough to make their way into the bloodstream.

First up was the smoke test. I lit a match a safe distance from the air purifier, let it burn for a few seconds, then blew it out. I expected the air purifier to pick up on the change in air quality relatively quickly, especially given how close the match was to the appliance. However, it took 2 minutes and 45 seconds for the LED indicator to change from blue (excellent) to green (very good). Another minute later, it shifted through yellow (moderate) and landed on orange (polluted).

I kept an eye on the app throughout, and after around 7 and a half minutes, the LED indicator had returned to yellow (moderate). Eventually, it worked its way back through green and into blue, taking 13 minutes and 7 seconds in total to declare the air quality excellent again. The purifier did the job, but it wasn’t the quickest on this occasion.

Next, I moved on to the aerosol deodorant test, which ended up being the area where the Blue Pure 511i Max most impressed me. After spraying a generous amount of deodorant directly in front of the appliance, I saw that it responded much faster than during the smoke test. Within less than a minute, the LED changed from blue to green and quickly progressed through yellow, orange, and red (very polluted). On the PM2.5 scale, it peaked at 370.

However, while it was quick to detect the problem, it was slower to resolve it. It took 20 minutes for the indicator to drop from red to orange, and longer still to make its way through to excellent again. That said, the air quality did drop significantly lower than during the smoke test, so the additional 7 minutes does make sense.

After the Blue Pure 511i Max had worked its magic, I couldn't smell any deodorant in the living room. While I don’t tend to use aerosol deodorants myself (this was my partner’s bottle), I do use dry shampoo regularly, which also releases VOCs. Knowing the purifier is sensitive enough to pick these up is reassuring.

Then, I moved on to the test I was most looking forward to – the bacon test. As this is usually the test that sends air purifiers into overdrive – cooking fumes do produce a strong aroma after all – I placed the pan right next to the air purifier to give it the best chance of picking up the fumes quickly. As with the smoke test, I was a little disappointed when nothing happened at first. For the first five minutes, the LED light stayed blue (indicating excellent air quality), and the app showed a PM2.5 reading of 0, despite the bacon sizzling away and producing tell-tale fumes.

Once the air quality started to register a change, though, things moved quickly. By six minutes, it had shifted to very good, and by 6 minutes 15 seconds, it was already at polluted. At 9 minutes, it had reached the very polluted level, indicated by the stark red light. The air quality peaked at 58 on the PM2.5 scale.

The path back to clean air during the bacon test wasn’t linear. The indicator bounced between orange, green, and red a few times before starting to settle. I turned off the heat at 13 minutes, and by 15 minutes 30 seconds, the air quality had recovered to very good. At the 18-minute mark, it had returned to excellent.

The final test I did with the Blue Pure 511i Max (and possibly the most glamorous) was the dust test. Emptying the vacuum is an easy way to release dust particles into the air, so it's always a bonus when an air purifier can detect these and adjust its fan setting accordingly.

I emptied the contents of my vacuum cleaner onto the floor next to the air purifier and waited for the LED indicator to register a drop in air quality. Despite keeping my eye on things for half an hour, the indicator remained stubbornly blue throughout. The app also showed no change on the PM2.5 scale, holding steady at 0. This was a little disappointing, especially compared to how quickly the air purifier responded to the deodorant.

That being said, I do use the Hoover HFX Cordless Vacuum to clean my home, which has a built-in HEPA filter. HEPA filters are designed to capture micro-particles of dust, so the contents that were released onto my kitchen floor might not have contained enough micro-particles for the air purifier to pick up on.

Ease of use

When it comes to usability, the Blueair Blue Pure 511i Max Air Purifier keeps things refreshingly simple. With just two buttons on the control panel – one for power, and one to cycle through modes – it's really easy to get the hang of, even if you’ve never used an air purifier before.

The buttons themselves are touch-sensitive and responded instantly every time I used them – an improvement on the last Blueair model I tested, where I often had to tap them more than once for them to activate.

Tapping the fan button cycles through the different modes: Auto Mode, which lets the purifier adjust its fan speed based on the air quality; Night Mode, which runs at the lowest fan speed and dims the lights for uninterrupted sleep; and manual fan speeds 1, 2, and 3. It’s all clearly displayed via the LED lights on the control panel, and the feedback is immediate.

If you don’t fancy getting up from the sofa, the Blueair app mirrors all of these settings – so you can adjust the fan speed, switch modes, or check air quality from your phone. I found this particularly useful after cooking, when I (sometimes) wanted to ramp things up quickly without leaving the comfort of the couch.

Overall, I'd say it strikes a good balance between keeping things user-friendly while still giving you enough control to tailor its performance to your needs.

Noise levels

One of the standout features of the Blueair Blue Pure 511i Max Air Purifier is how quiet it is – especially on the lowest fan setting. According to the product specifications, it runs as quietly as 19dB, and I was able to verify this using an independent app. Most of the time, I left it on Auto Mode, and because my home’s air quality (thankfully) shows as excellent most of the time, it rarely needed to crank the fan speed up. As a result, I often couldn’t even hear it running unless I was right next to it.

On higher fan settings, it does get noticeably louder – particularly on level 3 – but even then, it tops out at 48dB. That’s still considerably quieter than some other models on the market, like the Shark NeverChange5, which reaches up to 66dB at full power.

During testing, the air purifier never needed to stay on its highest setting for more than 30 minutes at a time, so the extra noise was easy enough to tolerate, knowing it was working hard to clear the air. Overall, if you're sensitive to sound – especially at night – this is one of the quieter air purifiers available.

Portability

When it comes to portability, the Blueair Blue Pure 511i Max isn’t the most travel-friendly option in the Blueair range – especially when compared to the Mini Max, which was designed with portability in mind. And especially as Blueair is marketing this model as their 'smallest smart air purifier.'

With a height of 48cm, it's a little on the taller side, but it's by no means heavy or awkward to carry around. It weighs just 1.29kg, which is impressive considering its size. There’s no dedicated carry handle, but it’s easy enough to pick up and move using both hands.

Personally, I'll be keeping my Mini Max to hand for when I want to quickly move it to a different room, and using the 511i Max as our 'main' air purifier, given it packs a more powerful punch and boasts smart connectivity features. But, the bigger model is still fine to relocate if you need to.

My only concern is that, with the device being on the larger side, I’ve had to be a bit more intentional about where I place it so it doesn’t end up feeling like it’s in the way. Thankfully, the minimalist design and neutral fabric cover mean it doesn’t stand out or clash with the rest of the room – so even when it’s not tucked into a corner, it never feels like an eyesore.

Energy use

The Blueair Blue Pure 511i Max is impressively efficient when it comes to energy use, drawing just 20W at full power. Based on the current Ofgem energy price cap, that means it costs less than 1p an hour to run – which is great news if the cost of running an air purifier is a concern for you.

There’s no dedicated Eco Mode, but given how little power it uses, it’s unlikely to make a noticeable dent in your energy bill. It’s a good option if you’re looking for a purifier that can quietly and consistently improve your air quality without driving up your running costs.

Filter replacement

Replacing the filter on the Blueair Blue Pure 511i Max is straightforward, with no guesswork involved, thanks to the indicator light on the control panel. When it’s time for a change, the light turns red to let you know

To access the filter, the top of the device twists off easily. From there, the fabric pre-filter and noise filter are removed, then the main filter lifts out using two built-in handles. Swapping in a new one takes just a few seconds. Once everything’s reassembled, I held the fan button down for 15 seconds to reset the filter indicator – all of which was outlined in the user manual.

You can buy a replacement filter for £24.53 on Amazon. It's not the cheapest, but it’s a worthwhile investment if you want to keep the purifier running efficiently.

As for the rest of the air purifier maintenance, the fabric pre-filter can be vacuumed with a soft brush attachment to keep it free from dust. It’s also machine washable, though you’ll need to let it dry for 12 hours before putting it back on the device. All in all, I'd say the Blue Pure 511i Max is a low-maintenance model with a filter system that’s easy to manage.

How does it rate online?

At the time of writing, the Blueair Blue Pure 511i Max Air Purifier has a strong 4.7 out of 5-star rating from 171 reviews on the Blueair website.

Customers have been particularly impressed by its ability to eliminate odours, with several noting that it effectively removes the smell of smoke, cooking, and even cat litter. Many also praised the sleek, minimalist design and how lightweight the unit is.

The Smart connectivity features have also gone down well with users, with reviewers appreciating how easy it is to monitor and control the device via the Blueair app. Overall, most users seem to agree it’s a solid performer that’s both practical and stylish.

Should you buy the Blue Blue Pure Max 511i?

If you’re after a stylish, low-maintenance air purifier that performs well in everyday home environments, the Blueair Blue Pure 511i Max is a solid choice. It’s easy to use straight out of the box, and the lightweight, compact design means it doesn’t feel intrusive – either visually or physically – even if space is tight.

Performance-wise, it's a strong all-rounder, responding particularly well to VOCs in our deodorant test. While its reaction to smoke and cooking fumes were slower than expected, the purifier did eventually restore air quality without needing constant input. It also failed to register a dip in air quality during our dust test, which was a shame. This might be because my vacuum's built-in HEPA filter had already done all the hard work, though.

But I think the positives definitely outweigh these drawbacks. The device's near-silent operation on lower settings and low running costs make it a great option for continuous use, and maintenance is refreshingly simple.

At 48cm tall, it’s a little bulkier than some portable alternatives – but if you’ve got a suitable spot for it, the neutral design means it won’t look out of place. Overall, it’s a solid pick for anyone looking to improve their home’s air quality with minimal fuss.

When I think of IKEA, I think of flat-pack furniture and meatballs. And while I admittedly love both of those things (ideally with lashings of gravy on the latter), there’s rarely been anything at IKEA for me - Ideal Home’s air quality expert - to sink my teeth into. But then I learned that the IKEA UPPÅTVIND Air Purifier exists, and I knew I had to give it a whirl.

After all, it’s my job to test the best air purifiers - and I have to admit that I’m the ideal candidate for these handy appliances as I’m a pet parent, hay fever sufferer and the owner of a very dusty house. However, it’s very rare to find an air purifier under £100, let alone under £30, so I was intrigued to see how such a budget model would fare in my home. My verdict? It’s cheap, cheerful, and surprisingly effective.

The IKEA UPPÅTVIND Air Purifier isn’t a new invention, as it was first launched in 2022, but I’d argue that it’s only really gained traction in the past few months as people become increasingly aware of the air quality in their homes. And one of the things I love most is how stylish and unobtrusive it’s been in my house during the testing process.

The specs are also pretty impressive, especially for something so affordable. Suitable for rooms up to 7m² (which is about the size of the average UK bedroom), it also has 3 fan speeds and a 99.5% filter efficiency.

Of course, it doesn’t come with a HEPA filter that many of the more expensive models offer, but that’s still enough to help you reduce the levels of dust in a home, remove low-to-medium levels of allergens from the air, and reduce pet dander for pet owners like me.

I will say that it’s not the most technologically advanced air purifier out there, and you’ll need to work out how many air purifiers you’ll need if you want whole-home purification, but I’ve found it perfect for taking the edge off high summer pollen levels and reduce the dust levels in my home.

In fact, it’s this dust-busting ability that impressed me more than anything else, as I typically find myself dusting way more than I’d like during the summer months. And while I tend to favour wet dusting over dry dusting (specifically with the Scrub Daddy Damp Duster, £3 at Amazon), I also favour not having to dust as often as I do - and I’ve noticed that I have to do it significantly less when I’m using IKEA’s UPPÅTVIND air purifier in my living room.

Not only that, but I find that I’ve been able to breathe easier as a hay fever sufferer, as air purifiers can help with allergies. This is especially true when I carry the UPPÅTVIND air purifier up to my bedroom using the handy carry handle and pop it on my bedside table overnight. On the lowest setting, it’s just 31dB, which is about the same level as a whispered conversation.

As I like a bit of white noise while I sleep, I don’t find it to be disruptive at all (although the light on the appliance itself is a little irritating), and actually find it quite relaxing.

Don’t just take my word for the impressive power of this appliance, though. The reviews of the UPPÅTVIND air purifier are also incredibly positive, with one reviewer writing, ‘This was recommended to me as I have long covid and hay-fever. So far I'm finding it works for me, I can really tell the difference if I don't use it.’

Another commented, ‘I only bought this to reduce the dust and cat dander, but after only 1 day, we both noticed the air just felt lighter and fresher when returning home, which isn’t something we were expecting to notice. We ended up going back to buy two more for other rooms. It’s not HEPA, but it’s a fraction of a % from it. For the price of the purifier, filters and low running costs compared to big brand filters, it’s a winner for me.’

It’s worth noting that you do need to replace the filter every six months (or more if you plan on using it heavily), but the replacement filters are just £3 at IKEA, which is ridiculously cheap.

And considering it’s £100s cheaper than competitors, I really would recommend this air purifier to those looking for a dust-busting appliance or those looking to improve the air quality in their homes.

If you have severe allergies or especially poor air quality, or want to invest in whole-home purification (in that case, I recommend the Dyson Big+Quiet), it might not be powerful enough, but it’ll certainly take the edge off while you’re busy choosing your next air purifier or if you have a smaller home.

Have you tried IKEA's air purifiers? This one has certainly impressed me!

Summer is prime time to be hot and stuffy - and I’m not just talking about the heat, either. But if you’re struggling with the impending heatwave and seasonal allergies, you’ll be happy to know that one of our top-rated solutions has been slashed by a whopping £200 in the Amazon Prime Day sale. Yep, say hello to your new summer saviour, the BLUEAIR ComfortPure T10i, now just £199 at Amazon.

Coupling one of the best fans with the best air purifiers, this 3-in-1 appliance is normally £399, which is admittedly a significant investment. But until midnight tonight, it’s cheaper than I’ve ever seen it, so you’ll have to act quickly if you want to snap it up.

As a growing trend in the cooling and home environment realm, air purifier fans are everywhere right now. We’ve also had the pleasure of testing the Blueair ComfortPure T10i, and can confidently say that - even at full price - it’s well worth the money. There’s no harm in getting a 50% discount, though, right?

After all, this appliance really does have it all. As the ‘most powerful triple function air purifier in the market,’ it’s primarily an air purifier, but the cooling function will also be a lifesaver during the heatwave as the ‘Cooling’ mode uses a dual jet stream to offer cold, purified air flow throughout the house.

Thanks to its sleek, compact design, it’s a whole lot smaller than even the best desk fans (and certainly the best portable air conditioners), which means it won’t take up too much space in your home either.

Plus, ranging from just 24-52dB, it’s also whisper-quiet, and our reviewer found that it mostly stayed within the 35.5dB mark in her house, which is about the same level as rustling noise. This means that you can keep a bedroom cool without it compromising on your sleep - which anyone who runs hot and struggles with hay fever will know is normally impossible in a heatwave.

Of course, I understand that this air purifier fan is still somewhat of an investment when you may have already bagged some Amazon Prime Day deals. But the fact that this air purifier can also double-up as one of the best heaters during the colder months is what makes this price even more enticing.

Instead of buying a fan that will take up storage space during the winter when it's not in use, you can continue using this appliance all year round. What a bargain.

You’ll need to be quick, though, as the Amazon Prime Day sale ends at midnight on the 11th July. And there’s no telling when it will be this cheap again.

This weekend is going to be HOT, so make sure you take advantage of these Amazon Prime Day deals before it's too late!

As Ideal Home’s resident air quality expert, I’ve made it my mission to know the ins and outs of the air purifier world. And while there are so many big brands staking their claim in this appliance corner, Dyson is generally considered the top dog. So, when I heard that the Dyson Purifier Big+Quiet Formaldehyde was the brand’s ‘quietest, most powerful air purifier,’ I knew I had to test it out.

Over the course of three weeks, I put the Dyson Purifier Big+Quiet Formaldehyde through its paces to see whether it has what it takes to compete with the best air purifiers available. My verdict? It’s quiet by name and quiet by nature - and while it might be pricey, I think it’s worth every penny if you really value whole-home purifying.

In a nutshell

On paper, the Dyson Purifier Big + Quiet Formaldehyde Purifying fan offers a wide range of impressive, science-led features - like the fact that it captures 99.9% of particles, can purify large spaces up to 100m², captures the urban pollutant NO², uses cone aerodynamics to circulate air and drive the pollutants back through the three-stage filtration, and is 50% quieter than any other Dyson air purifier.

But I know that, to some people, that’s all a bit overwhelming. What you really want to know is whether it works… and how well it will fit into your house. And after being initially doubtful that something so large and expensive would be able to find a home in my house, I’ve eaten my hat. This air purifier fan is quiet, powerful, stylish, and one of the most impressive air purifiers I’ve ever tested.

The ability to purify large rooms is this air purifier’s USP, as its 100m² range means it has the power to purify entire homes (after all, the average semi-detached home measures around 90-95m²) or open-plan spaces, offices, classrooms, or shops. And throughout testing, I really did feel as though my home’s air quality improved massively.

An app or a remote control easily controls everything you need from the Big+Quiet, it’s incredibly customisable to your home and routine, a whole wealth of air quality information is at your fingertips (and phone), and you don’t have to worry about replacing the (very high-tech) filters every six months.

My only niggles were that the reaction times were a little slower than I expected, and there’s no denying the fact that this air purifier is big. However, aside from that, I really do think it’s a worthy investment for those looking for whole-home purifying.

N.B.: It’s worth noting that I tested the Dyson Purifier Big+Quiet Formaldehyde BP04, which is exclusive to the Dyson website. However, the BP04 is almost identical to the BP03, which is more widely available and also a bit cheaper. The only differences are the colourway and the fact that the BP04 also comes with a CO2 sensor and an improved activated charcoal filter. Aside from that, the specs are virtually the same.

How I tested

Unboxing and setting up

From the name alone, I had expected the Dyson Purifier Big+Quiet to be big, but I didn’t expect the box it came in to be such a beast. In fact, even the delivery driver commented on the mammoth size of the box and struggled to get it up the front steps to my house. I then struggled to heave it into my dining room by myself, so it’s worth taking that into account if you have mobility issues or don’t have someone on hand to help.

I was a little disappointed to see that the box was also encased in plastic, as I didn’t think this was necessary (or eco-friendly). However, for a product of this price, I do understand the extra layer of protection. I just wish there had been more information on the plastic to tell me whether it was recyclable or not.

However, I was greeted with a lot more eco-friendliness when I opened the box. Aside from plastic encasing the air purifier itself, everything else was protected in cardboard shells, and I was also relieved to see that there weren’t too many pieces to assemble. I didn’t even have to unwrap or assemble any of the filters, as these were already in place within the machine itself.

I did want to take a sneak peek at the filters, though. So, I pressed the red buttons on the inside of the gold casing and lifted it up. This was almost like a set of Russian dolls, as you have to lift the first HEPA filter up to get to the K-carbon filter, and it was extremely efficient.

Then, I attached the cone head to the main unit, attached the remote control to the magnetic strip (a feature I REALLY like as I’m notorious for losing small remote controls), and then grabbed my phone to connect it to the MyDyson app for real-time data and extra controls.

This was easy enough, and all I needed to do was download the app, scan the serial number of the model, turn the air purifier on, hold my phone near it, and then press the button on the actual appliance. The app then asked me to indicate the location of the air purifier, and as I’d set it up in my living room, I selected that option before sitting back and letting it do its thing for a while.

Design

Air purifiers are a bit like Marmite - you either love the look of them or you hate them. And while some air purifiers are simply white, unassuming, and blend into the background, it’s fair to say that the Dyson Big+Quiet Formaldehyde can’t and won’t ever do that.

Not only is it big, but it’s also an unusual shape and pretty bold in terms of its colourway - no matter whether you opt for the ‘Prussian Blue and Gold’ of the BP04 like me or the ‘Nickel and Prussian Blue’ of the BP03.

In fact, the design is unmistakably Dyson. And as a Dyson fan, I don’t mind it, but I can see how both the size and design could be a turn-off for some, as there’s just no hiding it.

However, there are some things that I do think could sway those sitting on the fence. The LCD screen on what I’m dubbing the head cone is extremely small and therefore won’t be distracting, there’s the magnetic strip on the gold outer casing to keep your remote control safe, and there’s even invisible castor wheels on the bottom of the appliance so you can easily move it around the house.

So, whether you like it or not, there’s no denying that a lot of thought has gone into the overall design of this appliance to make it unique.

Ease of use

Although I test all manner of appliances as part of my job, I’ll be the first to admit that I don’t like complicated controls, and I immediately mark something down if it takes me more than a minute to understand how I’m supposed to use it. Thankfully, this wasn’t the case with the Dyson Big+Quiet.

In fact, one of the things I loved most about it was just how easy it was to use. This is largely because there are two ways to control the settings of this appliance: through the remote control or the app. Admittedly, you can’t do as much with the remote control, but you can turn it on and off, adjust the fan speed, check the air quality stats, and even angle the fan at the push of a button.

I’m more of an app person, anyway, so this limited functionality didn’t bother me. Instead, I used the Dyson app to control and monitor everything. And when I mean everything, I really do mean everything. Through the app, you can easily set timers, connect to voice assistants like Alexa and Google Home (something I don’t have but imagine will be very useful if you do), and adjust all of your fan and speed settings.

Of course, this is also where you can check all of your air quality data, which is extremely detailed and admittedly a little overwhelming at first. And while I’ve tested and used many air purifiers in the past, the Dyson Big+Quiet reveals more pollutants than I've ever experienced.

On the less intense side, the air purifier monitors temperature and humidity - something I didn’t necessarily pay much heed to during the summer months, but is something I’d probably appreciate more in the winter when I want to keep the condensation in my Victorian house at bay.

On the more intense side of things, the Big+Quiet also monitors the following:

• Particulate matter PM2.5 (microscopic particles smaller than 2.5 microns, like smoke)
• Particulate matter PM10 (microscopic particles smaller than 10 microns, such as pollen and other allergens)
• Formaldehyde HCHO (a colourless, flammable gas that is often found in furniture and paint)
• Volatile organic compounds VOCs (harmful gases caused by cooking and found in cleaning products)
• Nitrogen dioxide and oxidising gases NO² (harmful gases released by combustion and cooking)
• Carbon dioxide CO² (often affected by how well a room is ventilated - but this is only available in the BP04, not the BP03 model)

On the app, each of these potential harmful pollutants is measured individually and has its own graph that you can monitor, but you can also look at your ‘overall’ air quality too, which encompasses all of them.

Personally, I really appreciated being able to see how my air quality fluctuated throughout the day and watching as the air purifier eventually reduced all the allergens to safe levels. But if numbers and graphs aren’t quite your vibe, you can also just look at the colour of the screen on the app.

Green indicates a ‘good’ air quality, light orange is ‘fair,’ and then it continues down to darker orange, light red, darker red, and finally purple for ‘severe.’ Thankfully, I only reached ‘very poor’ during my testing process, which coincided with the height of a sanding and painting session in my house. I can only imagine what kind of home you’d need to live in to go all the way down to purple.

Performance

Any air purifier can look nice and have easy-to-use controls, but the most essential feature of any air purifier is actually to clean the air in your home. To test this, I wanted to put the Dyson Big+Quiet through our specific testing process.

I ensured that my air quality was ‘good’ and then switched it to ‘Auto’ mode. Then, I began with the match test, which involved lighting a match near the air purifier and letting it blow out to observe its reaction. Amazingly, it didn’t take long (around 20 seconds) for the Big+Quiet to notice a change in the air quality, and I could see the CO² and PM2.5 levels rising quite quickly.

It took about five minutes for these levels to reach their peak before they started to reduce as the air purifier worked its magic gradually. And all in all, it took around 15 minutes before my levels had dropped back to where they had been previously.

Next, I moved on to the deodorant test, which tests an air purifier on its ability to remove VOCs from the air. This time, it took around two minutes for the Big+Quiet to react to the introduction of this harmful aerosol, and I was also surprised to see that both the VOC and the formaldehyde levels increased with the deodorant.

This had me frantically Googling why that would be the case, and it turns out that many spray deodorants also contain formaldehyde as a preservation measure. So, I’ve actually switched to a natural roll-on deodorant since then, as we should all try to avoid formaldehyde exposure at all costs. Thankfully, the VOCs and formaldehyde levels didn’t increase as drastically with the deodorant test, and my air quality returned to normal levels within 7 minutes.

After the deodorant test, I moved on to the (vegetarian) bacon test. I assumed that my gas hob coupled with the cooking fumes would cause a big reaction from the Big+Quiet, and I wasn’t wrong. Just 30 seconds after the bacon started sizzling, my air quality worsened, and the ‘Auto’ mode turned itself up a notch to deal with the changes.

Then, it took around 20 minutes for my levels to return to normal after I’d finished making my bacon sandwich, and I couldn’t even smell any lingering bacon odours after that time, either.

Finally, I moved on to the dust test. For this one, I emptied the contents of my vacuum cleaner in front of the air purifier and waited to see how it would react. All in all, it took around three minutes for it to notice a slight change, and within another five minutes it was back to normal - so, it didn’t make too much of a dent in my already-very-good air quality.

As my air purifier testing process also coincided with myself and my husband sanding and re-painting the skirting boards in our house in preparation for some new flooring, I also got to unofficially ‘test’ the Big+Quiet during many DIY sessions - and it’s safe to say that the whole thing made me feel a bit sick.

My graph would constantly enter the dark red levels on the graph while sanding and painting (after all, I was introducing both dust particles and VOCs into the house), and it really put the air purifier through its paces. But the Big+Quiet had no problems bringing everything back down into the safe zone when we’d finished. This impressed (and horrified) me immensely, as I could really see how hard it was working to keep my home healthy.

And while I will say that the reaction times of this air purifier are quite a bit slower than many other air purifiers the Ideal Home team has tested, I don’t exactly see this as a negative. Sure, having to wait a little longer isn’t ideal, but I felt extremely confident in the air purifier’s ability to do its job to the highest calibre - and it actually made me question how cheaper, less powerful air purifiers are able to do the same thing in a shorter amount of time.

This also isn’t a new thing, as Dyson air purifiers are known for being a little slower to react than the masses. Our reviewer also found this with the Dyson Hot+Cool Formaldehyde Air Purifier, which continues to be one of the brand’s bestselling and top-rated products. So, slower doesn’t necessarily mean worse.

It’s also worth mentioning that the Dyson Big+Quiet is technically a fan, too, as the delivery of up to 80 litres of purified air per second creates a cooling effect. On a recent visit to Dyson HQ in Malmesbury - yes, I do have the coolest job ever - I had the opportunity to speak with the air purifier engineers, who explained that it’s this air circulation that makes the air purifier so effective. After all, many air purifiers claim to purify the air, but successful purification relies on air circulation, too, which is why this particular model is so powerful.

And as I tested the Big+Quiet during a June heatwave, I found myself using it in place of a fan and angling the air in a way that cooled both myself and the room, so this was a great feature. I do wonder how much I’ll appreciate this in the winter, though.

Noise levels

Marketed as Dyson’s ‘quietest air purifier,’ I expected the Big+Quiet to be on the quiet side - but what I didn’t expect was for it to be almost silent.

On paper, the brand says it provides 56 decibels of noise (dB), which is about the same as a quiet conversation. But what I’d like to clarify through my own testing is that I picked up a reading of 57dB on the HIGHEST speed setting. On its quietest setting, I measured a reading of just 37dB, which is comparable to a whisper.

And while this doesn’t make it the quietest air purifier the Ideal Home team has ever tested - that honour goes to the Blueair Blue Max 3250i Air Purifier - it’s still one of the quietest. This impressed me immensely, especially as it’s also extremely powerful, which normally translates to a loud machine.

In fact, sometimes I'd check that Big+Quiet was still on, as it was so quiet I wondered whether I’d accidentally turned it off. It really is that quiet.

Portability

One thing I was worried about when I initially saw the Big+Quiet was how I’d be able to carry it from room to room. However, the reality is that I didn’t need to move it during testing, thanks to its 100 m² coverage. This meant that, even if I kept it in my living room, my entire home was being purified.

That said, Dyson has still thought about portability. The unit itself isn’t heavy (just a little awkward in size), and it comes with discreet wheels which aren’t visible when the appliance is upright. So, you can just push it around the house if you have hard floors. If you have carpet, it’ll be a little trickier, but not impossible.

Filter replacement

Although there are so many positives to air purifiers, replacing the filters regularly is a definite negative. That’s why I was happy to learn that I wouldn’t need to replace the filters of the Dyson Big+Quiet regularly. Additionally, the machine will notify me when the HEPA, Activated carbon, and Selective Catalytic Oxidation filters need to be changed.

In the three weeks that I’ve spent testing this air purifier, I can see that I’ve only used 1% of the carbon filter's life - and I still have 100% left in my HEPA.

This coincides with Dyson's recommendations, which suggest replacing the HEPA H13-grade filter after using it for up to five years (unless the machine indicates an earlier replacement is necessary) and the K-carbon filter every two years. Thankfully, the Selective Catalytic Oxidisation (SCO) filter is permanent and never needs replacing. 

When it comes to replacing these filters, Dyson recommends that you buy straight from the source, and these will set you back £60 each. To be honest, I was expecting that to be worse, so shelling out £60 every two years and another £60 every five years isn’t as bad as other air purifiers out there.

How does it rate online?

There are currently 78 reviews of the Dyson Big + Quiet Formaldehyde on the Dyson website, with an average star rating of 4.6 out of 5. Of course, one of the biggest concerns many of the reviewers had was the size of the appliance, but one customer wrote, ‘The concerns go away pretty quickly as soon as I start using it.’

That’s because customers rave about the air quality information the Big + Quiet provides, finding it far superior to other models on the market. They also love how quiet it is, even on higher fan settings. And, most importantly, they feel as though it has made a significant improvement in the air quality of their home.

Verdict: Should you buy the Dyson Purifier Big+Quiet Formaldehyde?

I won’t lie and say that the Dyson Purifier Big+Quiet Formaldehyde suits everyone, because it won’t. I’m not even sure I’m the perfect customer for this appliance, as my house is a little too compact to make the most of it.

However, I’m writing this review a week after I stopped officially ‘testing’ it - and I’m still using it willingly, because it impressed me that much. So, I think that has to stand for something.

But all in all, I think those who have larger, more open-plan homes or want to invest in their family’s health and air quality would benefit from this air purifier, as the information this Dyson offers at your fingertips is unmatched. The build quality is also incredible, and the app functionalities are wide-ranging and impressive. Of course, the air purifying properties are second to none, as you’d expect from such a high-ticket item.

However, if you live in a smaller house and just want something to take the edge off your hay fever symptoms or your battle a bit of dust, the Big+Quiet will undoubtedly be overkill. In that instance, it’ll suit you better to opt for something cheaper, smaller, and perhaps a bit louder.

The Levoit Core 600S, RRP £299.99 at Amazon, might just be the best air purifier for you if you want a smart workhorse of an air purifier that can boost your home’s clean air on a daily basis. With an ultra-efficient True HEPA filter system and plenty of smart features, including a handy app, the 600S promises to tackle allergens, smoke, odours and other airborne nasties in large spaces. I tested it over two weeks in a real family home with pets, subjecting it to dust, smoke, and cooking smells, among other everyday pollutants, to see how well it performed.

It didn't disappoint! I’ve tested dozens of premium air purifiers over the past five years, and I can confidently say that the Levoit is one of the most powerful air purifiers on the market, despite being more affordable than many big brand offerings. It might be a bit of a beast in terms of size, but its no-fuss setup, ease of use, and reliability in performance make it one of the best air purifiers for any home. Here’s why.

In a nutshell

The Levoit Core 600S might not be the smallest or most stylish air purifier in an increasingly large and innovative market, but in my considered opinion, it delivers impressive results.

I tested it over a couple of weeks in my large, open-plan living and dining room, bedroom and galley-style, busy kitchen. It quickly cleared the air after all my toughest tests, including cooking fried food, lighting matches, spraying deodorant and releasing vacuum dust. It also dealt swiftly with, ahem, pet gas and other everyday odours.

Its three-stage True HEPA filter traps particles as small as 0.3 microns, and it has a dedicated carbon filter to neutralise VOCs and lingering smells. The auto mode and laser dust sensor make it a ‘set and forget’ appliance, automatically adjusting the fan speed based on real-time air quality, which is also displayed for you at any time.

Despite its size, the Levoit Core 600S is surprisingly quiet and can blend into most modern homes’ aesthetic. Even on its highest setting, it stayed below 50 decibels - about the same as background music. Add in app and voice control via Alexa or Google Assistant, and it’s a dream for smart home fans.

How I tested

Unboxing and setting up

The Levoit Core 600S comes in a sturdy cardboard box with a mix of recyclable cardboard packaging and plastic bags, which may or may not be recyclable, depending on where you live. Also in the box is the pre-installed filter, a user manual that is clear and straightforward (and also available online in case you lose it), and a quick start guide.

Once you’ve unpacked the purifier, the first thing you've to do, as with all Levoit purifiers and many other brands, is to remove the filter from inside the appliance, discard the plastic wrapping, and reinsert it.

This is super easy; simply twist the top half of the air purifier anticlockwise and lift it off to remove the filter. Remove the plastic wrapping and reinsert it, resecuring the top half. Once that’s done, it’s ready to plug in and start playing with.

What you notice right away is how substantial the 600s feels. It’s not a small machine, but it doesn’t feel clunky or industrial either. Setup is genuinely easy, especially connecting it to the VeSync app.

I just scanned the QR code, followed a couple of steps, and within minutes, I was monitoring real-time air quality data and playing with multiple settings from my phone. For something this powerful, it’s surprisingly beginner-friendly.

Design

While it’s fairly large, the Levoit Core 600S does quite a good job of blending into the background of a modern family home. It’s sleek and semi-cylindrical, featuring a perforated base, soft, rounded corners, and a matte white finish that makes it look more stylish than your average air purifier.

For most of the time during testing, I tucked mine into the corner of my open-plan living room between a chair and a coffee table, and it didn’t catch the eye too much or feel like an unnecessary distraction from my decor, although it might stand out a little more if you have a more traditional or bohemian feel to your home. If I were to give it a permanent spot, I'd probably tuck it behind the coffee table next to the wall, allowing enough space for air to circulate.

It's big, though - at 60 cm tall - it’s not ideal for small bedrooms or tight flats unless you’ve got the floor space to spare. It’s also not suitable for shelving or bedside tables, which might put some people off.

I had to move a few items of furniture to ensure it had the recommended clearance of 38 cm on all sides, so it’s worth measuring your available space before committing to buy it.

I really liked the design of the touch-sensitive control panel, which is at the top of the unit. It features an attractive ‘wheel’ design with multiple air outlets, including a power button, display lock, auto mode, and fan speed controls. You can also see WiFi connectivity, filter status and real-time air quality.

The digital display shows the number of 2.5-micron particulates in your home’s indoor air at any given time, which is a great way to check how well the 600s is coping with pollutants and other airborne contaminants. It’s intuitive and easy to read, featuring soft-touch buttons and a glowing LED ring that gave me an instant visual cue about my air quality in real-time, glowing red for warning and green for good to go.

I also like the fact that the 600s is designed in such a way that air is pushed out through the top in a vertical flow, which avoids the chilly breeze some purifiers give off and (I think) helps distribute clean air across the room more evenly.

If you’re after a more compact design but you appreciate the technology and features that Levoit offers, you could plump for the smaller, more desktop-friendly Levoit 300S Air Purifier, which stands just 36cm tall, almost half the height of the 600S. Or you might like a model that doesn’t look like an air purifier at all, in which case you may prefer the much sleeker and stylish Dupray Bloom Air Purifier, which can be used as a planter and a side table, as well as an air purifier!

Performance

According to Levoit, this unit can purify up to 294m² in just 12 minutes—and based on my experience, I’d say that’s more than realistic. I put the Levoit Core 600S through its paces using the same series of tests we regularly carry out on air purifiers here at Ideal Home. I also assessed its day-to-day performance in a busy family home with long-haired pets.

First up, the fried food test. My partner whipped up a batch of beef brisket chunks, complete with chilli and spices. It wasn’t long before the air was thick with strong cooking odours and the smart sensor maxed out at 999 for PM2.5 particles — the highest reading it can register.

Within moments, the purifier detected the spike and automatically increased its fan speed to its maximum setting. Once the frying was finished, I timed how long it took the 600S to restore the air to a healthy level. I was genuinely impressed — it took just six minutes for the display to shift from red (bad) to green (good), and the lingering food smells vanished almost as quickly.

Next came the deodorant test. I closed all the windows and doors in a bedroom, sprayed a generous amount of deodorant, and waited to see how the purifier would respond.

Within seconds, it identified the surge in airborne particles and kicked into high fan speed. Air quality returned to a moderate level in about 2.5 minutes and reached a green “good” rating within 4.5 minutes.

Next, the match test. I lit two matches, blew them out near the purifier, and tracked its response. After 40 seconds, the sensor flagged poor air quality. It took just under five minutes to return to moderate levels, and a further 2.5 minutes to achieve a green “good” rating again.

The last test involved emptying a dust cup from my vacuum next to the air purifier to see if it would trigger an air quality warning and increase fan speeds. It did not, however, I think that might be to do with the fact that my Dyson V15s already has a powerful HEPA filter that traps harmful air particles.

While it's not an official test, I also noticed that when my rather large dog passed wind, the Levoit was quick off the mark at identifying it, even before we did (!) and got to work at dispelling those odious odours. Needless to say, this happened quite a lot.

Overall, I was impressed with how speedy the 600S was at identifying problem particles and how fast it worked to rid them from my indoor air.

Ease of use

Despite being a high-spec machine, the Core 600S is refreshingly simple and easy to use. The top control panel is clear and responsive, but I mainly used the Vesync app, which lets you switch modes, adjust fan speed, set schedules, and even check the filter status. However, it has a tendency to be a bit glitchy on occasion, so it's something to watch out for.

The voice assistant compatibility is a nice bonus as well. Once I had linked up with my son’s Alexa, I could just say “turn on the air purifier” without lifting a finger.

The Auto Mode meant I didn’t have to think much about it on a day-to-day basis, either. It would quietly ramp up when needed and settle down once the air cleared. I also liked the Sleep Mode, which dims the lights and drops to near-silent operation at night.

Maintenance is super simple, too. The filters are easy to change, and there’s a helpful reminder in the app when it’s time to replace them (approximately every 6 to 12 months, depending on your usage). I liked that I didn’t need to remember or guess—just tap the app, and it tells you exactly how much life is left in your filter.

You do need to remember to clean the outer filter every 2–4 weeks, though, as this will maintain efficiency and extend the life of your filter. You can clean it using a soft brush or a vacuum hose to remove hair, dust, and any large particles. Don’t clean it with water or any other liquids.

You’ll also need to clean the laser dust sensor every three months by placing your vacuum hose over the sensor openings for around 10 seconds. The manual provides instructions for all necessary maintenance and troubleshooting advice.

Noise levels

For something this powerful, the Core 600S is impressively quiet. On its lowest setting, I could barely hear it running, even sitting right next to it. During Sleep Mode, the hum is a whisper-soft 23 decibels, which didn’t disturb my sleep at all.

On higher settings, especially when Auto Mode ramps up during cooking or heavy cleaning, it becomes noticeably more pronounced. At top speed, the noise level can reach around 50 decibels, comparable to a fan on medium. But it’s not harsh or grating—it’s more of a smooth whooshing sound, which I didn’t find distracting, even while watching TV.

If you’re sensitive to sound, you might notice it during peak performance, but for everyday use, I found it blended into the background easily. I never felt the need to switch it off for peace and quiet.

Portability

Although it’s lighter than it looks, the 6.3kg weight and the larger 31.3 x 31.3 x 60 cm dimensions of the Core 600S mean you’re unlikely to switch it from room to room, and you may need help moving it around if you have mobility issues. However, it does have two built-in handles on either side to make moving around easier.

Energy use

With a maximum draw of 66 watts, the Levoit Core 600S is certainly not an energy guzzler. It costs around 2p per hour to run, which is comparable to the cost of a laptop or an energy-saving light bulb.

Auto mode also helps keep its energy use down, plus it’s Energy Star certified, which should give budget-conscious buyers some reassurance.

This guide on the cost of running an air purifier in the home can help you determine the cost on a weekly, monthly, and yearly basis.

Filter replacement

The Levoit 600S features a single cylindrical HEPA filter with an integrated carbon layer. Levoit claims its filter can last up to 12 months, depending on usage, but you can monitor filter life via the Vesync app.

Replacement filters from Levoit aren’t cheap, costing around £70, but they are easy to swap out — just twist the top off the unit and insert the new one. It’s also possible to buy off-brand filters that are compatible with Levoit devices, but be aware that Levoit states that using off-brand filters could affect both performance and reliability, as well as the status of your warranty.

How does it rate online?

The Core 600S boasts thousands of glowing reviews online, earning a 4.6-star rating out of 5 on Amazon, with 81% of customers giving it a full 5-star rating.

They love its ability to tackle smoke, allergens, and odours, with many noting how noticeably fresher their homes smell. Many even say it reduces bouts of coughing, allergic reactions and illness in their homes, with one user stating, 'Only used it today, and air feels fresher and not coughing anymore. Worth the money, especially as other brands can be twice the amount,' and another noting that 'We use it whenever we have visitors, including when my son visited with his toddler daughter and they both had colds. We did not get their colds!' It’s also widely praised for its quiet operation and the handy app.

There aren’t many negative reviews, but some users find it noisy on the highest fan settings, while others say the app can be a bit glitchy - something I noticed in my testing too. A fair few users also complain that Levoit replacement filters are too expensive.

How does it compare to similar models and predecessors?

Compared to the Core 300S and 400S, the 600S is larger, more powerful, and better suited to open-plan spaces. It also features a more detailed PM2.5 display and enhanced smart sensor technology. While it’s undoubtedly bulkier, I reckon its performance more than makes up for the extra size.

Compared to other brand leaders, such as Blueair or Dyson, I’d say the Core 600S offers similar purification, but at a significantly lower price. While it doesn’t have a cooling fan like Dyson’s models or incorporate a dehumidifier like DryZone or Meaco, the ease of use and sleek design make it a winner for me, plus the affordability makes it more achievable to get cleaner air with a smaller budget.

Verdict: Should you buy the Levoit Core 600S air purifier?

I’ve tested dozens of air purifiers over the last five years and have consistently found that Levoit purifiers deliver on clean air quality. Plus, they’re easy to set up and use, and you can forget they’re even running in the background.

If you’ve got the space, I’d say the Levoit Core 600S is one of the best air purifiers you can buy. It’s ideal for open-plan homes or larger rooms and will suit allergy sufferers, pet owners or anyone living in a polluted area.

If your space or budget is tight, the Core 300S or 400S might be better suited to you, but if you want top-tier performance without breaking the bank, the 600S is a great choice.

If you have an air purifier, chances are it's working hard in your kitchen. But have you considered that it could be in the wrong spot? Knowing where to place an air purifier in a kitchen is key to making sure it's doing its job properly.

After all, the best air purifiers are designed to remove unwanted smells, fumes and airborne pollutants, especially those that spread through your home as a result of everyday cooking. But, here's the catch (and it's worth knowing before you buy an air purifier) – they only work effectively if you use them correctly.

That's why the Ideal Home team test all air purifiers in the kitchen, and that includes our bacon test (yep, it's a thing!), as part of our air purifier testing process. And to help you get the best results, we've asked air purifier experts to share their top tips for where to place an air purifier in a kitchen – and why it might not be where you think...

1. Close to the cooker (but not too close!)

Let's face it, if you're using an air purifier in your kitchen, one of the reasons (if not the main reason) is to get rid of lingering cooking smells. So, it's natural to want to place your air purifier next to the source of those odours. But experts warn that placing it too close to the cooker could actually reduce its effectiveness, or even cause damage.

'Don’t place your air purifier directly next to the cooker as this is ground-zero for smoke, oil particles and steam,' explains Katie Lilywhite, air treatment expert at AO.com. 'You’d be better off putting it a few feet away, as you could potentially clog it with grease from your cooking,' she says.

This advice is echoed by Chris Michael, co-founder of Meaco, who agrees that proximity matters.

'If cooking creates smoke or strong odours, it is best to place the purifier closer to the cooking area, but not so close that it might be exposed to heat, splashes or steam,' he advises.

2. On the kitchen worktop

If your kitchen allows it, placing your air purifier on a small worktop or countertop can make a noticeable difference. You could even make the most of 2-in-1 air purifiers, like the IKEA side table air purifier.

'Air purifiers tend to work better when they’re roughly around three to five feet off the ground so they can capture any contaminants where they linger most,' advises Katie.

That said, it's not a one-size-fits-all rule. Like choosing whether air purifiers are better placed on the floor or a desk, it really depends on the size of the unit. Larger air purifiers tend to be better placed on the floor, believes Lars Dunberger, head of technology at Blueair.

'While smaller, countertop-sized models may be suitable for targeted use in smaller spaces, air purifiers are typically more effective when placed on the floor, as this allows them to capture heavier particles that settle lower in the room. This is especially true in kitchens, where smoke and odours are at play,' he says.

3. Away from open windows and vents

It's natural to want to crack open the windows while cooking to let fresh air in, but if you do, make sure your air purifier isn't positioned too close to them. While air purifiers work with windows open, you'll generally see best results in a controlled airflow environment.

'When using an air purifier, windows should be closed,' says Stephan Lang, residential product specialist at Daikin UK. 'This is because they have a larger volume of air to deal with, and the unfiltered air from outside will contain pollutants.'

Stephan also warns that open windows also make the unit work harder, reducing its life expectancy as well as increasing energy costs.

Additionally, you should also be careful not to place the air purifier anywhere that blocks the air vents in your kitchen.

4. In an open, well-ventilated area

Another golden rule when it comes to placing an air purifier in a kitchen is to ensure it's in an open, well-ventilated area. In fact, experts advise that there should be at least 10cm clearance around the unit to allow proper airflow in and out.

'The most central positioning in the room is a great way to encourage efficient air flow and draw in air from all directions, ensuring that all corners of the room benefit from clean air,' says Lars.

Steer clear of enclosed or cluttered spots as this could restrict the unit's airflow. 'Avoid putting the purifier under cabinets or inside cupboards, as this blocks airflow and reduces performance,' advises Chris from Meaco.

This may mean that you have to move other kitchen appliances, cookbooks, crockery, or even plants out of the way to use your air purifier in the kitchen, but it will be worth it for the improved air quality.

5. Near the kitchen bin

'Position your air purifier near common sources of indoor pollutants for maximum effectiveness,' recommends Stephan from Daikin.

And one thing you might not realise is that the kitchen bin is one of the biggest culprits, so popping your air purifier near here can help to neutralise lingering odours.

'Air purifiers with filters that include an activated carbon layer are particularly great for eliminating odours, so positioning these near kitchen bins or even cat litter boxes is a great way of keeping your kitchen odour free,' advises Lars.

You'll just need to make sure you have enough clearance around the air purifier for proper air flow, and avoid spots where it could be exposed to spills or moisture from the bin.

FAQS

Where should you not put an air purifier?

Placement is key when it comes to getting the most out of your air purifier, and there are a few spots to steer clear of.

'Avoid placing your air purifier next to any of your appliances like a kettle or hob as this puts your appliance at risk of moisture or steam damage,' warns Katie from AO. 'Similarly, a window ledge or placing it in direct sunlight could equally play havoc with its internal sensors.'

Other no-go areas include places where the unit inlets or air outlet is obstructed, or combustion based heating or other high temperature devices and away from any TVs or radios.

How do I purify the air in my kitchen?

Still wondering if air purifiers are worth it? When it comes to tackling lingering cooking smells and kitchen fumes, they're real game-changers.

If you can, opt for one with a combined HEPA (High Efficiency Particulate Air) filter to capture airborne grease and allergens, and an activated carbon filter to neutralise stubborn odours. Just make sure you don't neglect to change the filter regularly!

It's also important to keep your kitchen ventilated by using your extractor fan. 'It’s not just a noisy gimmick, it is a vital appliance to help suck out the moisture, smoke and any cooking smells before they spread and potentially roost,' says Katie. 'Keep yours on when you’re cooking and be sure to turn this off after so your air purifier can do the heavy lifting without interference.'

There you have it, an expert-approved list of where to place an air purifier in a kitchen to get the best results. Let us know if you have a favourite kitchen-spot for your air purifier?!

Knowing whether air purifiers work with windows open is a common dilemma, especially as the weather warms up. After all, it's natural to want to let fresh air into your home throughout spring and summer.

However, the downsides of cracking open the windows to combat higher temperatures is the rise in pollen, dust and airborne pollutants. This is where the best air purifiers can be a real life-saver as they can help with allergies and generally improve air quality at home.

So, this leaves us wondering – do air purifiers work with windows open, or is it counter-productive? And if they struggle to keep up with outdoor pollutants, are air purifiers worth it during the summer months when you're more likely to have the windows open? I consulted the experts and asked them to weigh in and settle the debate.

Do air purifiers work with the windows open?

While it may seem like air purifiers are simple appliances, there are many things I wish I'd known before buying an air purifier, including how to use them properly. And although I now know I should leave an air purifier on while cleaning, I've always questioned, 'do air purifiers work with windows open?'

The short answer is yes – but there are some caveats. The general consensus among the experts is that while most air purifiers will still work with windows open, it's not ideal.

'Air purifiers can still function when a window is open, but they may not be as effective,' warns Dyson engineer Shawn Navarednam.

This is because the air purifier may struggle to keep up with the constant influx of outdoor particles, such as pollen, dust, and pollution – which makes it trickier if you're trying to pollen-proof your home.

Katie Lilywhite, air treatment expert at AO.com echoes this; 'Your air purifier will work when the windows are open, however it will be far less efficient. These appliances rely on circulating and filtering the air in enclosed spaces and face an uphill struggle when windows or doors are left open.'

So, what should you do?

Noel Fok, CEO and co-founder of EcoAir, explains that while opening windows is essential for maintaining good indoor air quality, it is best to turn your air purifier off while windows are open.

'It will have to work harder to remove outdoor pollutants from the new air coming in and this can affect overall performance,' he says. In fact, you may find that your air purifier will go into overdrive and ultimately cost more to run.

'Ideally, open windows - and doors - in various rooms for 5-10 minutes each day to create airflow and refresh the air in your home and then, once windows are closed, turn your air purifier back on so it can get to work purifying the refreshed indoor air,' Noel recommends.

That being said, it's not a major issue if you do want to open the windows for brief intervals while your air purifier is running, believes Shawn from Dyson.

'If ventilation is needed for comfort or safety, keeping the window open for short periods is fine, the purifier will still help clean the air, but it could be at a slower rate,' he advises.

So, while your air purifier can still work with windows open, for best results you should switch it off while you ventilate the room if you want to maximise its efficiency.

There is another solution worth considering, though, and that's investing in a combined air purifier-fan. As air purifiers don't cool a room, these hybrid appliances will cool the room and at same time filter out airborne pollutants. This makes them a smart choice for warmer months when keeping windows shut isn't always practical.

FAQs

Do air purifiers work if the door is open?

Air purifiers do work with the door open, but it's worth noting that their effectiveness will be greatly reduced.

'If the door is open, untreated air keeps flowing in, so the purifier cannot fully clean the space,' says Chris Michael, chair of Meaco.

'It will still filter the air that passes through it, but it will not be able to keep on top of the whole room. You will get much better results with the door closed so the air stays contained and the purifier can do its job efficiently.'

That said, if you prefer to keep internal doors open – particularly when it's warm – being mindful of where you place your air purifier can help. Positioning it deeper into the room you want to target will ensure it's filtering the air where it's most needed.

Where should you not put an air purifier?

Air purifiers also work best in locations with maximum movement or air – for example, close to windows, doors or walls.

'Avoid placing it behind furniture or under shelves, where airflow is restricted, or near radiators where extreme heat may damage the machine. These spots can block the circulation of air, making it harder for the purifier to clean the whole room,' warns Shawn from Dyson.

You also need to make sure that there's around 3-5 feet of clear space around the air purifier so that it can work to the best of its ability and maintain constant airflow.

Do air purifiers work in an open room?

Whether an air purifier works in an open room is a difficult one, as it's not a simple answer.

'They can help, but not as effectively as in a closed space,' says Chris from Meaco. 'New air keeps coming in, so the purifier has more to deal with. You just need to make sure you get one that’s powerful enough for the size of the space.'

The experts agree that for larger, open spaces, opt for a more powerful model with a decent Clean Air Delivery Rate (CADR) – which measures the volume of air the air purifier can filter, or clean, in a given timeframe.

Alternatively (and budget dependent), you might want to place two air purifiers at opposite ends of the room to help clean air circulate throughout.

So, will you be keeping your windows open or closed this summer? If you want your air purifier to work to the best of its ability, it's best to keep them closed.

With spring in full swing and the pollen count climbing by the day, there’s never been a better time to invest in an air purifier fan.

So when the brand new Dyson Purifier Cool PC1 landed on my doorstep, I was eager to put it through its paces with all of us suffering badly with the sniffles. Known for their sleek design and smart technology, Dyson’s latest model promises to deliver powerful cooling while quietly clearing the air of allergens and pollutants.

I tested both its fan performance and air purifying abilities to see how it fared against smoke, dust, and household odours and to find out whether it truly deserves a spot among the best air purifiers and best fans on the market.

In a nutshell

I found the new Dyson Purifier Cool PC1 to be both sleek and modern, while also boasting whisper-quiet cooling and purifying performance. During my testing, it tackled everything from everyday dust to lingering cooking smells, leaving the air fresher in a matter of minutes.

It cooled down the rooms in our house gently without the distracting hum you often get from traditional fans, making it ideal for bedrooms or even home offices. Like many a Dyson, it’s at the pricier end of the scale, and other models can match its purifying power for less, but where most fall short is in the finer details, and the PC1 doesn’t just have style.

It’s packed with smart technology like its Air Multiplier technology that others simply haven’t mastered yet, from its real-time air quality sensors in its Auto mode to the helpful app control, all wrapped up in a design you’ll actually want to show off and not hide away.

Unboxing and setting up

Unboxing the Dyson Purifier Cool PC1 was refreshingly fuss-free, which is a rare treat when so many gadgets arrive swaddled in layers of unnecessary packaging. Dyson keeps it simple: the unit comes fully assembled, snugly slotted into two perfectly moulded inserts and wrapped in a protective layer of plastic.

There were no fiddly screws or cryptic instructions to contend with. All I needed to do was peel off the wrapping, plug it in, and it was ready to go. I had it up and whirring away in under five minutes.

Setting up the Dyson Purifier Cool PC1 couldn’t have been easier, especially if, like me, you already have the MyDyson app from using the Airwrap. I simply opened the app, tapped “Add New Device,” and scanned the barcode on the fan.

Within seconds, it was registered, connected to Wi-Fi, and ready to go. Just make sure you take all the packaging off before you start... I made the rookie error of leaving the plastic wrap on the base and tried to test the oscillation. The fan didn’t love that and instantly flagged a fault. Once I removed the wrap, it was smooth sailing though.

It comes with a compact little remote control that’s surprisingly intuitive, which has all the main functions like fan speed, oscillation, auto mode, and night mode. It cleverly attaches magnetically to the top of the fan so you’re not constantly losing it down the side of the sofa, or misplacing which I am nearly certain I would do.

Ease of use

Whether you’re using the remote or the MyDyson app (which, by the way, is refreshingly straightforward), everything is clearly laid out and easy to get to grips with, especially the resources section on the app with the many helpful how-to videos.

The air quality LED display is another big win. A quick glance at the colour gauge tells you everything you need to know, with green meaning the air’s in great shape, while red and purple are your cue to let the Dyson do its thing on the auto mode.

And the app also shows your indoor data, and I was very happy to see that our air quality in our home was 'Good'.

Design

Straight out of the box, the Dyson Purifier Cool PC1 is a striking bit of kit. It's sleek, sculptural, and unmistakably Dyson. If you’ve seen a Dyson fan before, you’ll recognise the silhouette instantly, with the signature bladeless oval loop giving it a slight futuristic look.

The control panel follows suit in its simple, slick design. It's discreetly nestled into the base, featuring a subtle black LED screen that only lights up when needed, displaying key information like air quality and fan speed without clutter or fuss.

And of course, it wouldn’t be Dyson without a bit of clever engineering. The Air Multiplier technology means it can deliver a smooth, powerful airflow that circulates clean, cool air around the room evenly.

The Dyson Purifier Cool PC1 is surprisingly lightweight, weighing just 4.72 kg, which makes it easy to move from room to room.

Although it’s quite tall and designed to sit on the floor, I had no trouble carrying it between spaces when needed, which is simple but much needed in a family home.

Performance

I put it through its air purifying paces with all the usual suspects: deodorant sprays, cooking smells and smoke.

It cleared smoke from a match I'd lit and blown out in 47 seconds, deodorant in one minute 33 seconds, and registered everyday dust from my vacuum in an instant, even though it did take a while to settle down once I'd cleared it up.

I even deliberately burnt some toast (all in the name of testing), and while it did struggle a bit at first, it eventually cleared the smell after about five minutes, so not instant, but still effective.

As a fan, it’s smooth, quiet, and powerful enough to push clean air across the whole room thanks to its wide 350-degree oscillation and 1-10 speed settings.

The Night mode dims the display and noise right down to keep things whisper-quiet, and it was easy to change things up once in bed with the remote and app.

Noise levels

The Dyson Purifier Cool PC1 operates at a maximum noise level of 61.4 decibels, but it's still relatively quiet. It's a winner for bedrooms or living rooms where you might be watching TV, as it won’t disrupt your downtime or make you crank up the volume to hear your favourite show.

Unlike some other fans and air purifiers I’ve tested, which can be distractingly loud, the PC1’s quiet performance blends seamlessly into your environment to the point where you might just forget it's there.

And, the Sleep mode reduces noise even more and dims the display, making it ideal for nighttime use to boot.

Maintenance

Keeping the Dyson Purifier Cool PC1 in tip-top shape is surprisingly simple. Every couple of months, you should give the exterior a quick once-over with a soft, damp cloth.

The filter is super easy to change, and Dyson makes it foolproof when you need to replace it. A little light pops on when it’s time for a change, and the app gives you an alert too.

Just click the plastic casing off the bottom of the unit, change the filter and click it back into place. The app also provides a how-to tutorial on how to replace the filter, so there are no excuses.

Energy use

As with most Dyson products, the Dyson Purifier Cool PC1 is designed with energy efficiency in mind. Operating at a maximum power of 50 watts, it consumes less energy than many other fans on the market.

In its Auto mode, the air purifier fan adjusts its operation based on real-time air quality, ensuring it only uses energy when necessary, which is a little nifty function that results in an average daily energy cost of roughly 5p for most users in the UK.

How does it rate online?

Even though it's one of Dyson's newest launches and is only months old, the PC1 is getting a lot of love already. On Dyson's website, it has a 4.6-star rating out of five from 35 happy customers, with an impressively high 88% of customers saying they'd recommend it to a friend.

Customers are particularly happy with its sleek, bladeless design, efficient air purification capabilities and quiet operation, and how great it is for allergy sufferers.

Verdict: Should you buy the Dyson Purifier Cool PC1?

If you’re on the fence about whether Dyson fans are worth it, I can safely give you my opinion on the Dyson Purifier Cool PC1. It’s a splurge, yes, but if you’re serious about air quality and cooling and in one sleek package to boot, I think it’s worth every penny. In my own home, I feel it tackles spring allergens and other household pollutants really well and looks good doing it.

And Dyson doesn’t skimp on the design either. It’s intuitive to use, the app is genuinely helpful (not just a gimmick), and it felt like a real upgrade rather than just another appliance. I may well consider passing on my other air purifier and pedestal fan. If you’ve got the budget, I say go for it because you definitely will notice the difference.

If you’re struggling with springtime allergies, waking up with a stuffy nose, or spending your days coughing and spluttering, your Googling may have pushed you in the direction of both air purifiers and humidifiers. But when it comes down to it, which one will suit you best?

The best air purifiers and the best humidifiers are inherently two very different appliances, but both can be extremely helpful throughout the year. In fact, they can soothe allergy sufferers and help those with lower immune systems breathe easier, sleep easier, and ultimately feel much better. However, choosing between the two can be difficult.

That’s why I’ve spoken to experts to solve the air purifier vs humidifier debate, comparing everything from how they work to their effectiveness and affordability. So, this is how to determine whether you need an air purifier or a humidifier.

What’s the difference?

Although air purifiers and humidifiers are often used to obtain similar results, they’re ultimately very different appliances that work in very different ways.

And at their core, air purifiers are designed to purify the air in your home of airborne pollutants like dust, pet dander, pollen, and VCOs. In fact, how well they remove these nasties is something we measure when we test air purifiers at Ideal Home.

They do this by sucking in the air and using filters to catch the pollutants and reintroducing the filtered, cleaner air back into your home. However, different air purifiers use different filters, so it’s very important to understand which type of air purifier you need.

Humidifiers work by releasing water vapour into the air and increasing the overall humidity of a room. They typically do this by blowing air over a wet filter or creating a mist that’s then expelled into the air. The main aim of a humidifier is to add moisture to a dry room and help you maintain the ideal humidity of the room, which should improve sleep and aid overall health and well-being.

Which is better for your allergies?

Allergies come in many shapes and forms, from allergies to pet dander to pollen. And in the air purifier vs humidifier debate, there’s no doubt that air purifiers help allergies better than humidifiers. After all, they tackle the root cause of your allergy symptoms.

As Dr. Jaspreet Dhau, VP of R&D at Molekule explains, ‘Air purifiers are designed to reduce allergen particles in the air, such as dust mites, pet dander, pollen or mould spores. Air purifiers have been found to be effective to reduce exposure to these triggers.’

If you opt for an air purifier that has a HEPA filter, it’s more likely to help hay fever, as these filters are designed to capture at least 99.97% of all allergens present in the air. This means your home is almost entirely free of potential triggers, and you can pollen-proof your home effectively.

This is something I experienced myself while testing the Shark NeverChange5 Air Purifier, as I found my hay fever symptoms (which typically make me feel incredibly stuffy and have itchy eyes) were drastically reduced when I used an air purifier for a couple of hours during the day and at night. Even today, I continue to use an air purifier throughout the year to keep my hay fever in check.

It’s worth noting that an air purifier might not be worth it if you choose to buy a cheaper model without a HEPA filter, though, as it won’t be as effective in reducing the cause of your allergies in your home.

On the other hand, humidifiers tackle the allergy symptoms themselves, rather than the airborne pollutants that cause the allergies or illnesses. Because of this, it’s largely seen as a short-term solution rather than a long-term one. But that’s not to say that a humidifier can’t help you at all.

As Dr. Jaspreet explains, ‘Humidifiers, on the other hand, have no impact on allergen levels. Instead, they may help allergy symptoms feel less severe if your nasal passages are dry and irritated.’ This can ultimately make you feel like you’re on top of your allergies, as you don’t have to battle the physical symptoms that you usually would.

However, Martin Seely, the CEO and sleep expert at MattressNextDay, warns that, if used too much, humidifiers can actually make allergies worse.

‘Humidifiers don’t remove allergens from the air, and if not cleaned properly, they can actually make allergies worse by spreading mould or bacteria,’ he says. ‘Over-humidifying can also create an environment where dust mites thrive, so it’s important to regularly check humidity levels.’

Which is better for sleep?

If you’re constantly searching for ways to sleep better, the air purifier vs humidifier debate has probably already crossed your mind. And, ultimately, they can both help you sleep soundly. Which one you choose is more of a personal choice, though.

Ideal Home’s Senior Digital Editor, Jenny McFarlane, swears by using a humidifier to help her two young daughters get to sleep. She told me, ‘We have a humidifier in each of the kids' rooms overnight, and they double as a nightlight and white noise machine, which helps them settle (relatively) faster. When they're fighting off a cough or stuffy nose, the humidifiers add moisture to the air in their rooms, which seems to soothe their breathing while they sleep, too.’

Humidifiers are also extremely effective for people who snore as a result of nasal congestion and throat irritation, as the extra moisture loosens the mucus and allows you to breathe easier during the night. This can also result in longer, deeper sleep periods.

However, air purifiers can also help you sleep better by filtering out the allergens and airborne pollutants that may otherwise interrupt a good night’s rest. This is echoed by Dr. Jaspreet, who says, ‘34% of people blame allergies for their sleep problems, second only to temperature (39%). Allergy triggers mentioned above are very small and can fragment into even smaller bits that cover the bed and are stirred up by motion in sleep, which can cause them to float in the air for minutes or hours.’

So, by keeping an air purifier on while you sleep, you can ensure that any nasties stirred up while you move in bed are captured and filtered out of the air so they don’t disturb you. There are some caveats to an air purifier’s ability to help you sleep better, though.

Martin says, ‘Air purifiers don’t add moisture to the air, so if dry air is also an issue, you may still experience discomfort like a dry throat or nasal passages. Some models can also be noisy, so look for one with a quiet or sleep mode.’

It’s also worth mentioning that you need to clean an air purifier regularly and make sure you keep on top of air purifier maintenance. For example, you need to replace an air purifier filter according to the manufacturer’s instructions to ensure it’s working as efficiently as possible at all times.

Which is more affordable?

When you’re choosing between an air purifier and a humidifier, affordability is something you definitely need to consider. After all, everyone wants to spend as little as possible on new appliances for the home.

In terms of air purifiers, the prices vary quite drastically. The cheapest air purifiers we’ve tested so far include the Russell Hobbs Mini Aroma Air Purifier, which retails for £49.99 and the more impressive Blueair Blue Pure 511 Air Purifier, which comes in at £99.99.

However, you could easily spend a lot more - and at the moment, the most expensive air purifier we’ve tested is the Dyson Purifier Hot + Cool, which will set you back a whopping £699.99. It is also a heater and a fan, though, so it’s technically three appliances in one.

On the other hand, humidifiers are typically a lot cheaper as they tend to be less technically advanced. You can generally pick one up for under £100 - sometimes even as cheap as £20.

Of course, you also need to consider how much it costs to run an air purifier and how much it’ll set you back to keep a humidifier running, but this will depend on the current energy tariffs. But generally, you’ll find that humidifiers are way more affordable than air purifiers.

Which one should you buy?

In the air purifier vs humidifier debate, it’s incredibly difficult to choose a winner, as both appliances have their positives and negatives. Because of this, it’s important to focus on your own concerns and decide based on your specific needs.

Martin agrees, and says, ‘If your main concern is allergies - especially in spring and summer, an air purifier is the clear winner, as it removes allergens from the air and creates a cleaner sleeping environment. If you struggle with dry air, particularly in winter, a humidifier is your best friend for soothing irritation and reducing snoring.’

With this in mind, you could even say that using both is ideal for reducing allergies and aiding sleep, as they should work in tandem to soothe your allergy symptoms and cut the triggers off at the root cause, too. If this is something you want to try out, it could be well worth investing in an air purifier and humidifier combo.

FAQs

Do air purifiers make the air dry?

No, air purifiers typically don’t make the air dry, as their main aim is to filter out airborne pollutants and improve the air quality rather than suck out the moisture (which is something the best dehumidifiers do).

However, it’s important to note that prolonged use of an air purifier can make people think that the air is becoming drier, as the increased air circulation speeds up evaporation of moisture on surfaces, making them dry out quicker. This will be very minimal, though, and in most cases you’ll barely notice it.

Is a humidifier or air purifier better for a cough?

Ultimately, this all depends on what is causing the cough. If you’re coughing due to cold or dry air, there’s no doubt that the extra moisture from a humidifier will ease your symptoms and help you feel better.

If your cough is caused by poor air quality or allergies like dust mites or hay fever, however, it’ll be better to use an air purifier as it will improve the quality of your air and filter out these cough-inducing pollutants.

So, which one will you be buying? An air purifier or a humidifier?

If you own an air purifier, chances are it's quietly working around the clock to keep lingering cooking odours, unwanted dust, allergens, and other airborne pollutants at bay. But should you have an air purifier on while you're cleaning?

There's no doubt that the best air purifiers are a game-changer when it comes to improving the air quality inside our homes. Whether you should leave your air purifier on all the time might be somewhat of a grey area, but there is one thing the experts are clear on - you should leave your air purifier on while cleaning.

'It might seem counter-intuitive, but cleaning can actually stir up more dust and allergens into the air, so it’s a great idea to switch your air purifier on while cleaning,' recommends Roisin Smith, professional cleaner at Wecasa. There are some things to consider, though.

Why you should have your air purifier on while you're cleaning

OK, so you don’t need us to point out that we clean to tackle built-up dust circulating in our homes. But what might not be as obvious is that everyday chores, such as vacuuming, can spread dust, and temporarily make the problem worse.

In fact, cleaning expert Barbara Stern at Ottoman Textiles, explains that many common cleaning tools, such as dry brooms or feather dusters, agitate the dust particles that settle on surfaces. And those dust particles need to go somewhere.

'For example, shaking out a rug sends a cloud of fine particles into the air. These allergens are often less than 10 microns in size and can remain suspended in the air for long periods, which allows them to be inhaled easily,' Barbara says.

This explains why symptoms may worsen during cleaning if you have asthma or allergies. And if you don't pollen-proof your home, this dust can also mingle with pollen and other airborne pollutants, which is why air purifiers are essential for those with allergies.

This is echoed by Chris Michael, Managing Director at Meaco, who says, Lots of people hoover their carpets and clean their surfaces of dust and other particles, but they don't clean the air - which is the source of the dust and dirt they are cleaning. This is where an air purifier comes in.'

But if you want an air purifier to work as effectively as possible while you're cleaning, there are some steps and decisions to consider.

Tips for having your air purifier on while cleaning

1. Choose an air purifier with a HEPA filter

Wondering which air purifier is best for you? When it comes to your cleaning routine, the expert verdict is unanimous - opt for an air purifier with a HEPA filter to see the best results.

'Choose an air purifier with a HEPA filter, which captures 99.97% of particles down to 0.3 microns - this includes dust, pollen, pet dander, bacteria, pollution, etc,' advises Chris.

He's not the only one who says so, either. Katie Lilywhite, air purifier expert at AO.com, also urges everyone to use an air purifier with this enhanced filter. She says, 'If you’re in the market for a new air purifier, then it's important you choose one equipped with a HEPA filter.'

She adds, 'These filters are a godsend for anyone who suffers with allergies, as they trap small particles - drastically improving your indoor air quality.'

2. Ensure the filter is clean before you start cleaning

Before you even reach for your cleaning tools, you should check that your air purifier is operating and the filter isn't clogged up with pet hair or dust.

'This helps to ensure that it removes any pollutants that are disturbed during cleaning', advises Hamid Salimi, residential property manager at Daikin.

To stay on top of maintenance, the industry pros recommend cleaning the filter at least every two weeks - although if you live in a household with pets or smokers, it's likely you'll need to clean it more frequently.

This shouldn't take too long, but it's important to note that the exact method does vary depending on the brand. For example, cleaning a Dyson filter may be different to cleaning a Blueair air purifier filter.

3. Keep all windows and doors closed

This one might surprise you, but those in the know advise closing your windows and doors while cleaning for your air purifier to work effectively.

To be more specific, Noel Fok, co-founder of EcoAir, says that the key is to open doors and windows in each room before cleaning and then closing them just as you're about to start.

'This will help to ventilate, letting fresh air in and stale air out. Then, when you enter the room to clean it, close the windows so that the air purifier can work on cleansing the air without any potential new pollutants coming into the room,' Neil advises.

Worried about how much your air purifier is costing to run? That's another reason to think twice about cracking open a window while cleaning, says Hamid from Daikin. 'Open windows will also make the unit work harder, reducing its life expectancy as well as increasing energy costs,' he says.

4. Turn your air purifier onto the highest setting while cleaning

While your air purifier works hard to get rid of dust, when you start cleaning, you're unintentionally stirring up a lot of airborne dust and allergens.

'These actions disturb settled particles like pet dander, pollen, and dust mites, which can then float around your home for hours before settling again,' Roisin from Wecasa says.

With that in mind, the expert recommendation is to use the highest setting for your air purifier while cleaning. 'You'll unsettle a lot of dust when cleaning, which will make its way into the air. Turning your air purifier on high will remove it from the air faster,' Chris from Meaco adds.

Of course, many modern air purifiers will automatically adjust their functions accordingly, but it's worth keeping an eye out if yours requires a manual setting change.

5. Ditch the duster

Even with your air purifier on while cleaning, you can't completely get rid of dust - but the good news is there is a hack to reduce it.

'Using a damp microfibre cloth instead of a dry duster can help reduce the amount of dust becoming airborne in the first place,' says Roisin (we also really rate this Scrub Daddy Damp Duster from Amazon).

In fact, this is one of the many reasons why the Ideal Home team always chooses wet dusting in the wet dusting vs dry dusting debate, as it's so much easier to capture the dust instead of moving it elsewhere.

Barbara from Ottoman Textiles echoes this advice: 'Spritz a little water or a gentle cleaning solution onto a microfibre cloth instead of directly onto the surface to avoid applying too much moisture, and to aid in dust sticking to the cloth rather than becoming airborne,' she says.

FAQS

Should I leave my air purifier on when I'm not home?

The general consensus is clear - to keep your air as clean as possible, it's best to leave your air purifier on, even when you're not at home.

'Leaving your air purifier on is perfectly safe and a practical thing to do even when you’re not at home. This will keep the indoor air quality consistent throughout the day, which means you’ll have less fuss to deal with when you return home,' says Katie Lilywhite from AO.com.

Worried about the cost of running an air purifier all day? Luckily, the majority of units are pretty cheap to run, but you can still reap the benefits if it's not switched on 24/7, says Noel Fok from EcoAir.

'If you are concerned about energy usage, you can operate the appliance on a lower setting whilst you are out of the house. If you live in a home where dust or allergens are not too problematic, you can run an air purifier for 12 hours a day with effective results,' he says.

Is there a downside to air purifiers?

By now, we're well aware of the benefits they bring to the table, but if you're still wondering if air purifiers are worth it, like most things, they come with some considerations.

Although air purifiers improve indoor air quality, excessive use can reduce humidity levels, drying out the air.

'This can cause dry skin, irritated sinuses, and breathing discomfort,' says Hamid Salimi from Daikin. 'This can be mitigated by not using it excessively, or opt for an air purifier that also humidifies.'

It's also worth noting that while most air purifiers use HEPA filters, some offer more powerful purification using UV light, ozone or ionisation to clean the air - which can produce harmful byproducts, warns Noel Fok, Ecoair.

'When purchasing an air purifier, be sure to check the quality of the product and its safety credentials to ensure your appliance is not emitting or leaking any dangerous chemicals or pollutants,' Noel advises.

That said, there's no denying air purifiers are great solution for improved indoor air quality in your home - especially if you suffer from allergies or respiratory issues. Like most investments, it comes down to what works for you personally.

So, now you know whether you should have an air purifier on while you're cleaning, it's time to get the vacuum out and turn your air purifier on!

If you have one of these handy appliances at home, chances are you haven't given much thought to when (and even if) you need to change an air purifier filter. But it's something you need to do... and often quite regularly.

The best air purifiers will trap dust, allergens and bacteria and keep the air in your home clean and healthy, but let's face it, regularly cleaning your air purifier probably isn't on the top of your to-do-list! However, like most household appliances, air purifiers require a little TLC to keep them running effectively for as long as possible.

Several factors can cause an air purifier to stop working - a faulty filter being up there. At some point, the majority of air purifier filters will need replacing in order for them to keep working properly (yep, it's one of the things I wish I knew before buying an air purifier). That's why I asked air quality experts how often you should actually change an air purifier filter.

How often should you change an air purifier filter?

Whilst there's no hard and fast rule when it comes to how often you should change an air purifier filter, as a general guide HEPA filters - which are the most common type - should be changed every 6-12 months. Carbon filters however, need replacing more often, every 3-6 months.

'To keep your machine in top condition, you should replace your air purifier’s HEPA filter once every 6-12 months, depending on frequency of use,' advises Noel Fok, CEO and co-founder of EcoAir.

Dyson engineer, Shawn Navarednam, agrees, 'It is recommended that air purifier filters are changed every 12 months following regular use, though it depends on pollutant levels in your home, where you live and how often you’re using the machine,' he says.

However, many air purifier brands are now designing models that require minimal replacements - if any at all. The filter of the Shark NeverChange5 Air Purifier will last an incredible five years before you need to change it, and the Vitesy Eteria Portable Air Purifier filter doesn't need replacing at all.

But as they're a relatively new addition to the air purifier world, it still remains to be seen whether this is truly the case. That's why it's a good idea to also good to know the signs to look out for that indicate it's time for an air purifier filter replacement.

The good news is they're all pretty easy to spot...

The 5 signs it's time to change an air purifier filter

1. Allergy or asthma symptoms worsen

Air purifiers can help with allergies, as they capture airborne particles, dust and pollutants in your home, reducing their presence in the air. Over time, the filter can become clogged and, as a result, will be unable to trap these allergens.

So, if you have asthma or suffer from seasonal allergies, such as hay fever, and your symptoms start to worsen, this is one of the biggest alarm bells that indicate you need an air purifier filter replacement.

'You may need to change your air filter more frequently if you experience allergy or asthma symptoms, or if you have pets,' Shawn advises.

2. The airflow isn't as powerful

Another obvious tell-tale sign that you need an air purifier replacement is if you notice the airflow in the room isn't as powerful.

'Reduced airflow could indicate that the filter is clogged or that its performance has been affected,' Noel says.

'HEPA filters, used in many air purifiers, are made up of a very fine mesh. Wear and tear over time will create tiny holes, inevitably affecting the number of particles captured,' explains Noel.

3. It starts to smell

Certain air purifiers are designed to remove unpleasant odours (is there anything this nifty gadget can't do?!). If you're asking yourself 'why does my air purifier smell?' then it could be a sign you need an air purifier filter replacement.

'Over time, a clogged or saturated filter can lead to lingering odours because activated carbon loses its ability to absorb smells,' says Lars Dunberger, head of technology at Blueair.

'In some cases trapped organic particles may also promote bacteria or mould growth unless the filter is equipped with germ busting technologies,' Lars explains.

4. The room looks dustier than usual

An air purifier is designed to trap dust in the air, so if you start to see more dust than usual circulating and built up on surfaces - it could mean the filter in your air purifier is clogged.

'A good way to know when it’s time to replace your filter is when you notice more dust buildup than usual from your air purifier,' says Noel from EcoAir.

'Using a filter which is filled with dust won't bring dangerous components to your home. But if the filter is full, it may be difficult for the clean air to come out and it might damage the air purifier in the long run,' warns Lars.

So, increased dust is yet another red flag that you need an air purifier filter replacement.

5. It's loud or making unusual noises

Whilst you'll probably struggle to find an air purifier that doesn't make a sound, if it starts to make strange sounds or it is generally getting noisier, chances are you need an air purifier filter replacement.

'Restricted airflow forces the air purifier’s fan and motor to work harder, which can create whirring, rattling, or buzzing noises as the system strains to push air through a blocked filter,' says Lars Dunberger at Blueair.

'Replacing the filter on time prevents this issues, ensuring the purifier continues to run quietly and effectively while keeping your air fresh,' he adds.

FAQS

What is the life expectancy of an air purifier?

Whilst we've made no secret of the fact we are big fans of this must-have appliance, air purifiers are an investment. If you're still weighing up if air purifiers are worth it, you'll no doubt want to know how long it's going to last.

When well-maintained, an air purifier should last up to ten years,' says Noel Fok, CEO and co-founder of EcoAir.

The life expectancy of an air purifier filter varies from manufacturer to manufacturer, says Hamid Salimi, residential property manager at Daikin.

'Some only last for a year whilst others last for up to 10 years. Irrespective of this you might need to change it more frequently. For example, if you use it regularly and if the air is heavily polluted, it will need to be changed more often,' advises Hamid.

'You should factor in the cost of replacing air filters when deciding on which air purifier to buy,' Hamid adds.

Can I clean my air purifier filter instead of replacing it?

This depends on the type of filter, but the majority of air purifiers use a HEPA filter, and unfortunately there's no shortcut when it comes to replacing them as they can't be cleaned.

Noel Fok from EcoAir says, 'HEPA filters in air purifiers are designed to capture tiny particles such as dust and pollen. These filters should never be washed as the water can damage the delicate material and create gaps, which would then allow airborne particles to pass through, reducing effectiveness.'

You can however clean the pre-filter, which catches larger particles to extend the life of the main filter, says Lars from Blueair.

'The pre-filter can be easily cleaned using a dust cloth or with a soft brush. For best performance, I'd recommend cleaning the pre-filter on a weekly basis,' Lars advises.

So, with all this in mind, there's no clear-cut answer as to how often you should change an air purifier filter. But it's still a necessary step if you use one of these handy appliances in your home.

As an allergy sufferer, I know an air purifier is key to a hay fever-free day. But as both myself and my husband also suffer from the sniffles and blocked noses at night, I’ve struggled to find an air purifier quiet enough to aid a symptom-free sleep… until now. Enter the Russell Hobbs Mini Aroma Air Purifier from Amazon! And it’s currently on sale for the Amazon Spring Deal Days event.

Yes, while I could shout about the best air purifiers until the cows come home, I’ve tested enough to learn that not all air purifiers are created equal. But with its whisper-quiet noise level, timer function, three speed settings, and even an integrated diffuser pad to add your favourite sleep-inducing essential oils, I’ve never slept as well as I have with this Russell Hobbs air purifier in my bedroom.

First and foremost, the Russell Hobbs bedroom air purifier is a surefire way to help you sleep with hay fever - and I can vouch for that. It’s specifically designed for medium-sized rooms up to 12m2 and offers a CADR (Clean Air Delivery Rate) of 100 m³/h, and advanced 3-layer filtration that effortlessly captures up to 99.95% of airborne allergens, including pollen and dust.

It also offers either a 2, 4 or 8-hour timer so you can decide whether you want to keep it on all night or just for a few hours.

Since testing it out for myself, I’ve opted to keep it on all night, and I’ve slept right through with no sniffly midnight wake-ups and no stuffy nose in the morning. My husband, who suffers from severe hay fever symptoms (especially in March and early April), has also noticed that his eyes have become less and less itchy with each passing day.

But that’s not all. The sleek Scandi design is a standout feature in my eyes, and I’ve found it easy for what could be an eyesore appliance to blend into my bedroom decor (which is more than I could say for the Shark NeverChange Air Purifier I tested recently, which offers a rather divisive design).

However, what I love most about this bedroom air purifier is just how silent it is. Although I’m used to the hum of appliances as one of Ideal Home’s experts for all things home tech, my husband is extremely sensitive to night noises and has to have complete silence to fall asleep.

In fact, we’ve never found an air purifier that we’ve been able to keep on all night, as he’s always had to turn it off - sometimes after just ten minutes. But the hum of the Russell Hobbs Mini Aroma Air Purifier is so insignificant that the decibel meter on my phone couldn’t even detect it. Yes, it’s that quiet.

If you find that essential oils help you sleep better, this air purifier also comes with an aromatherapy function to create a calming sleep environment. Just add a few drops of your favourite scent to the integrated diffuser pad to circulate in your bedroom as you sleep.

So far, I’ve been using this NEOM Feel Good Vibes Essential Oil Blend from Amazon, but I have my eyes on the NEOM Bedtime Hero Essential Oil Blend from Amazon to boost my sleep quality even more.

The only thing I will say is that the lights on the top are a little annoying if you need a pitch-black bedroom to fall asleep (like myself). But I managed to solve this problem by laying a sock over the controls, making sure not to make an air purifier mistake and covering the vents at the top in the process.

Plus, who can argue with this price point? Even at its recommended RRP of £49.99, this bedroom air purifier is considerably cheaper than other options on the market - but the 20% reduction for the Amazon Spring Deal Days event is the cherry on top.

After buying an air purifier a few years ago, I now can’t imagine my life or my home without one in it. But you probably don’t think of Shark when it comes to air purifiers, which is why I was intrigued to test whether the cult floor care brand’s model could compete with the big fish in the air purifier pond.

After testing (and being won over more than I anticipated), I can safely say that the Shark NeverChange5 Air Purifier definitely has what it takes to be considered one of the best air purifiers out there. This is why.

In a nutshell

Alien-like in its appearance and an unexpected side-step for the floor care brand, the Shark NeverChange5 Air Purifier HP150UK may divide opinions in terms of its design, but its quick response time and odour-eating qualities can’t be scoffed at.

Featuring a NeverChange5 Filtration System that means you won’t need to replace the filter for five years (which is 10x the lifespan of some other air purifier filters) and an Anti-Odour cartridge that releases a fresh scent as it cleans the air, it’s effective and practical.

Plus, with the ability to purify areas up to 60sqm with one air change per hour or rooms of up to 12sqm with 4.8 air changes per hour, it’ll benefit any size home.

After testing for three weeks, my home feels (and smells) noticeably cleaner, it’s become easier to breathe during the height of hay fever season, and I’ve felt confident that the Clean Sense IQ technology has successfully monitored and reacted to changes in my environment. The only slight downsides? The price and the design.

How I tested

Unboxing and setting up

The Shark NeverChange5 Air Purifier arrived on my doorstep in a fairly lightweight and compact box, and I was instantly impressed to see that the whole thing was recyclable and eco-friendly.

The air purifier was encased in a cardboard shell, and wrapped up further in white recyclable paper. Also in the box was a quick-start guide, information on the guarantee (one year as standard, two years if you register the appliance with Shark within the first 28 days of purchase) and the Anti-Odour Dial & Cartridge.

As I’ve used quite a few air purifiers now, I know that the setup of every air purifier can be different. So, I followed Shark’s guidelines to turn the appliance upside down, place it on a level floor, and then turn the filter door anti-clockwise to remove the rather hefty HEPA filter and remove it from its plastic packaging. Then, I placed the filter back in its home and turned the filter door clockwise to lock it back in place.

And while using the Anti-Odour cartridge is optional for this particular model, I wanted to test the Shark NeverChange 5 Air Purifier in its entirety - so I opened up the recyclable tin (not unlike a tin of tuna, but with a much nicer scent) and popped the cartridge into the designated slot in the top of the machine. Then, it was ready to use.

Design

I’ll be honest: I think the design of the Shark Shark NeverChange5 Air Purifier will be divisive - especially in a world where more and more people are jumping on the aesthetic air purifier train. After all, it’s pretty unique.

Personally, I wasn’t sure how I felt about it when I first laid eyes on it, and I’m still not sure how I feel about it after having it in my home for the last three weeks. Like many others, I like my appliances to blend into the background of my home decor (which is why I have previously used the relatively unassuming Philips 800 Series Air Purifier in my house) instead of sticking out like a sore thumb. But the modern design of the Shark air purifier looks more like an alien spaceship than a typical home appliance, and it's hard to ignore.

However, I should note that modern home decor isn’t my style - so those who prefer these clean lines and angular shapes may love it and find that they want it to stand out of the crowd. As someone who prefers a more rustic look, though, it did look somewhat out of place in my house. So, it could go one of two ways.

One thing I will say, though, is that the air purifier is incredibly light, and at 3.32kg, it is actually one of the lightest air purifiers the whole Ideal Home team has tested. The lightest of all time still goes to the 1.25kg Vitesy Eteria Portable Air Purifier, but the Shark is a considerable amount lighter than the MeacoDry Arete One Dehumidifier & Air Purifier, which comes in at a whopping 15.1kg.

Plus, I like that the Shark NeverChange5 air purifier has a long cable - especially for someone who lives in a house with a limited number of plug sockets. The LCD screens on the front and the top of the air purifier are also incredibly easy to use, and it doesn’t take a lot to translate what these symbols and numbers mean when in use.

Performance

On paper, the Shark NeverChange5 Air Purifier HP150UK has much to offer. From the four layers of powerful filtration (including NanoSeal HEPA to capture dust and smoke, Activated Carbon to neutralise odours and gases, a Pet Particle Barrier to guard against dander and allergens, and an easy-to-clean DebrisDefence pre-filter) to the Clean Sense IQ technology that constantly monitors the air quality and automatically reacts to changes in the environment, it seems impressive.

However, we have strict rules to follow when testing air purifiers at Ideal Home to see whether these claims are actually warranted. So, I knew I couldn't take this air purifier at face value and needed to test its various features to understand how it truly performed.

The first test? I waited for my air quality to enter into the ‘Good’ category (between 85-100%) before lighting a match and blowing it out to create smoke near the appliance.

In Auto mode, it took just 6 seconds for the Shark air purifier to register the smoke particles, for the air quality percentage to start dropping, and for the indicator colour to start changing. As a result, it automatically changed its setting to increase the fan speed and remove the smoke from the air. Then, it took just five minutes for the air quality to return to ‘Good.’

I was incredibly impressed by the quick response time as it was considerably less than the Blueair Blue Max 320i Air Purifier, which we’ve crowned the ‘best overall’ in our guide. In fact, the Blueair model took 20 seconds to register the smoke in the air - 14 seconds more than the Shark model.

Ever the critic, though, I wondered whether this was just a fluke. So, I proceeded to the next air purifier test, the VCO test. To complete this test, I sprayed a liberal amount of aerosol deodorant in front of the air purifier to see whether the response time would be just as impressive… and it was!

This time, it took around 4 seconds for the air quality percentage to start dropping (although, strangely, the percentage increased momentarily just as I was spraying it) - and while this decrease was quite gradual to begin with, it suddenly dropped quite dramatically as it reacted to the VCOs in the air. Again, it took around 5-7 minutes for the air quality to return to ‘Good.’

The third air purifier test I conducted was the cooking test to see how well the Shark air purifier dealt with cooking fumes. Although I have an open-plan kitchen and living room, I shut my living room door, made sure all of the windows were closed and left the extractor fan turned off while I fried two rashers of vegetarian bacon. I positioned the air purifier to the side of the hob, a safe distance away but still close enough to test the responsiveness.

I must admit that the Shark air purifier did, at first, take a little while (3 whole minutes) to react to the gas hob being fired up - but after slowly kicking into action, the air quality percentage then began to drop rapidly. And as it continued to drop, the fans started whirring away, quicker and louder.

After I finished cooking, it then took just 12 minutes for the air quality to rise from just where it had dropped to 28% back to its starting level of 98%. I thought this was pretty impressive.

The final test I performed was the vacuum dust test. After all, vacuuming can spread dust - not just while you’re using it but also when you’re emptying your vacuum. So, I emptied the contents of my vacuum cleaner onto the floor next to the Shark NeverChange5 air purifier to see how it would respond.

Although the air quality decreased slightly, it didn’t drop too much. However, that might also have something to do with my vacuum cleaner, as the incredibly advanced Dyson Gen5detect comes with its own HEPA filter to collect a lot of the smaller particles.

During all of these tests, it’s also worth noting that there weren’t any lingering odours left after the air purifier had worked its magic. This seemed to be because the air purifier had captured and absorbed all of the pollutants, but also because of the odour cartridge that hits you with a fresh scent as soon as you turn it on.

You can tailor the intensity of this smell by twisting it left or right, and I must admit that I loved this extra feature as it’s not something I’ve seen with an air purifier before. The scent is extremely pleasant and another great way for the air purifier to neutralise the everyday odours that come from a house with an open-plan kitchen, pets, and neighbours who regularly waft smoke over the fence.

Ease of use

I’ve used a few air purifiers over the years, and I often find that they either fall into one of two categories - they’re either too simple (with just an on/off button and very little else), or they’re too complicated (with numerous buttons, apps, and functionalities). But in my eyes, the Shark NeverChange5 Air Purifier falls comfortably in the middle of those categories.

There are two screens on this particular model, including the LCD touchpad on the top of the appliance and the LCD screen on the front. The touchpad is fairly self-explanatory and offers you the chance to change mode, adjust the fan speed, set a timer, dim the lights for nighttime use, turn on the child lock, or look at the air info.

It’s this air info button that then changes what you see on the screen on the front of the air purifier. Personally, I tended to keep the air quality percentage on this screen as I found this the easiest to understand and interpret.

You can also see the colour ring on the front display, which informs you of your air quality. ‘Good’ is blue and means your air quality is between 85-100%, ‘Fair’ is orange and between 70-84% and ‘Poor’ is red and between 0-69%.

But if you want, you can easily view the amount of Particulate Matter (PM) in your air on this screen. To do this, you simply toggle between PM10 (which measures dust and pollen), PSQ M.5 (smoke and pollution) and PM1 (allergens). The colour rings will also be present in this mode, and all in all, it was incredibly easy to use.

Noise levels

Compared to other air purifiers on the market, the Shark NeverChange5 Air Purifier HP150UK is on the louder end of the spectrum. On its lowest setting, my decibel meter found it to be around 35 decibels - double that of the Blueair Blue Max 320i Air Purifier.

However, as someone who regularly tests and uses household appliances like the best dehumidifiers and the best electric heaters, I don’t find this noise to be too distracting as I’ve become accustomed to this white noise. 35dB may be a lot for some people to handle though - especially if you want to use an air purifier to help you sleep (although the dimmable night mode does mean that you can turn off the appliance’s lights, at least).

And while the Shark specs suggest that the highest setting comes in around 66 decibels, my decibel meter found that to be a slight overstretch. Sure, the highest fan speed setting is noisy, but I found it to be around 60dB.

This is something that I can personally live with as there are still air purifiers out there that are louder (I’m looking at you, Dyson Purifier Hot+Cool Formaldehyde), but I do appreciate that there are also much quieter options on the market. So, if sound is something you’re sensitive to, this is something you should consider before buying.

Portability

In terms of portability, the Shark NeverChange5 Air Purifier is incredibly lightweight and relatively compact. It weighs just 3.32kg, and the dimensions come in at H38.5cm x W23.7cm x D26.6cm, which means it isn’t too awkward or heavy to carry from room to room.

However, one thing I learned the hard way is that the mesh filters on the side look like they should be carry handles… but they’re not. If you attempt to lift the appliance this way, you’ll just remove the filters instead, and I made this mistake quite a few times before I just bear-hugged the air purifier around my house instead.

The lack of a carry handle does take away some of the portability of the appliance, but its lightweight nature still makes it easy to carry around - even if you’re not the strongest.

Energy use

Compared to other air purifiers we’ve tested at Ideal Home, the Shark NeverChange5 Air Purifier is relatively efficient. Using just 26W in Auto Mode, this puts it firmly in the middle of the pack - and it seems as though Shark designed it to be more eco-friendly, too.

In fact, if this model achieves 100% air purification status for 5 minutes in Auto Mode, it will automatically enter Eco Mode and use less energy. If your air quality changes, however, it will swing itself back into action and go back into Auto Mode.

But it’s this small detail that will help you out when it comes to how much it costs to run an air purifier in the home.

Filter replacement

Generally, one of the main aspects of air purifier maintenance is replacing the filter. However, Shark claims that the high-performance HEPA filtration in the Shark NeverChange 5 Air Purifier won’t need replacing for up to five years - supposedly saving up to £200 in replacement costs.

As I haven’t used the air purifier for anywhere close to five years and it was only released a short while ago, these claims can’t be backed up just yet. However, it’s certainly a selling point, as the only real maintenance you need to do for this particular model is to clean the Mesh Dust Filters.

When these filters need cleaning, the front display will show a pulsing red ring and you should see the ‘check dust filters’ warning come up on the screen, too. Then, the easiest way to clean them is to pull them up and use a vacuum cleaner (in its handheld form and with a soft brush attachment) to remove any lingering debris.

If you can’t do this, you can either use a clean cloth or rinse them under water. If you choose the latter option, you’ll need to wait at least 12 hours for them to dry before popping them back in.

Shark also recommends cleaning the exterior of the air purifier every two months using a damp microfibre cloth, and clean the interior of the HEPA filter every two months using either a damp cloth or a vacuum cleaner. You should never use any chemicals or cleaners for any part of your Shark air purifier maintenance.

The only other form of maintenance is replacing the Anti-Odour cartridge every three months or as needed, which comes at an extra cost. At the time of writing, the cost of a Shark Anti-Odour Technology Replacement Cartridges two-pack will cost you £15.99. You can use the air purifier without these cartridges, though.

How does it rate online?

At the time of writing, the Shark NeverChange5 Air Purifier HP150UK rates extremely highly. With over 100 reviews on the Shark website, it has an overall star rating of 4.7 out of 5 stars.

Customers have praised the quality of the product and the Anti-Odour cartridges, and many have claimed that the air purifier has helped them breathe easier in their homes - especially those who struggle with asthma or hay fever.

However, some customers have experienced a problem where their air quality has been stuck on 100% all the time. In some cases, the customers returned their air purifier and exchanged it for another, which then worked perfectly fine. Shark does offer a free 2-year guarantee, so this is worth noting if you do find yourself experiencing a similar problem.

Verdict: Should you buy the Shark NeverChange5 air purifier?

Although I have a few air purifiers at home, the Shark NeverChange5 is the one I always find myself reaching for - and I think that says a lot about whether I think this particular air purifier is worth it.

The impressive response time, coupled with the ease of use and the addition of the scent cartridge makes it an effective and enjoyable way to clean the air in a home. I also felt that my house felt noticeably cleaner while I was using it.

My only niggles are the design and the fact that it’s on the pricier end of the spectrum. There are many air purifiers cheaper and more aesthetically pleasing than this one, so I do think this may put people off.

However, I really can’t fault it in terms of its performances, so I do think it’s worth the investment if you’re looking for a high-quality, effective air purifier and are serious about your home’s air quality.

Briiv, the UK-based air purifier manufacturer, has released the latest version of its eco-friendly and sustainable air filter, the Briiv 2 Pro Air Filter - and you might have already spotted it (or its predecessors) making the rounds on social media. After all, aesthetic air purifiers are in right now, and I don’t see them going away anytime soon.

Offering a terrarium-style aesthetic and the filtering power of 3,043 houseplants, this air filter uses renewable materials like moss and coconut fibre to compete with the best air purifiers out there. And with its sleek, natural style and its ability to rid your home of airborne pollutants and potentially harmful particles, it’s fair to say that it’ll be a welcome addition to any bedside table, kitchen counter, or living room.

However, the Briiv 2 Pro Air Filter isn’t the only air purifier that seamlessly blends both style and substance. As we’ll see, other manufacturers are entering the ‘aesthetic air purifier’ game - and I can’t decide which one I love most. Especially as some of them are much more affordable.

Having an air purifier in the home is a non-negotiable in my eyes. Not only do I live with a dog and a seasonal allergy sufferer, but I also have family members with asthma who visit us regularly. Because of this, having top-notch air quality is incredibly important to me - just as it should be for everyone else.

But while the benefits of air purifiers are hard to ignore, it’s fair to say that the size and appearance of these appliances can put some people off, as they’re typically quite large and often big and clunky. That’s where the Briiv 2 Pro Air Filter can fill the void.

Using the concept of biophilic design to its advantage, this eco-friendly air purifier primarily uses a moss filter to remove impurities and pollutants from the air - one of the reasons why so many experts urge us to grow moss in pots for a healthier home.

This moss filter focuses on pollen and other allergens like pet dander, while a smaller coconut fibre filter removes dust, dirt, and smoke from the air, an activated carbon filter tackles VOCs and gets rid of smells, and the nano matrix filter targets finer particulates that could harm your health.

As you can tell from the name, the Briiv 2 Pro Air Filter is an advanced iteration of a younger model - and this new release also offers AI-powered sensors for effective air monitoring, a built-in diffuser (so you can add the essential oil of your choice), automatic activation, and it can be linked to additional Briiv filters to combat your entire home. If you don’t want to make the most of the latter option, you can still rest easy knowing that this air filter can clean the air in a 4x4m² space in just 21 minutes.

This newer version isn’t available to buy on Amazon just yet and the original has sold out at John Lewis (although there are a few stores that still have click and collect available) - which shows just how popular it’s become. But you can still buy through Briiv directly.

However, the Briiv Air Filter isn’t the only aesthetic air purifier out there. In recent years, manufacturers have started to stray away from big, bulky appliances and are opting for stylish alternatives that integrate seamlessly into your home instead - from an air purifier that can double up as an indoor plant pot to air purifiers that serve as a bedside table simultaneously.

This allows homeowners and renters alike the chance to blend their appliances into their homes without compromising on style… or space.

But if you're sold on the Briiv, you'll be happy to know that Ideal Home’s Deputy Digital Editor, Rebecca Knight, tested the original Briiv Air Filter in September 2023 - and she gave it a very respectable 4-star review. And while she (obviously) loved the look of this air filter, there were a few niggles that meant she was unable to award it the coveted 5-star rating.

Her only criticism of the original Briiv Air Filter focused on a lack of functionality and difficulties in terms of turning it on and off, so the fact that the Briiv 2 Pro Air Filter comes with extra functionalities and this automatic activation suggests that the company has listened to feedback from customers and solved the initial problems. As such, they’ve created an aesthetic air purifier that offers both style and substance - albeit for a rather hefty price.

With more and more options coming out of the woodwork, it’s clear to see that aesthetic air purifiers aren’t going anywhere. In fact, I don’t think it will be long before major manufacturers follow suit and offer newer, more stylish air purifiers for the wider market. After all, IKEA has already made waves with its stylish side table air purifier.

But if you're still on the fence, it’s worth researching which air purifier is right for you before you part with your money.

I know one thing for sure, though. The Briiv Air Filter Pro is coming home with me…

For this Vitesy Eteria portable air purifier review, I put this new cost-effective and sustainable indoor air purifying solution through its paces. I'll also see how it fares in comparison to the best air purifiers the Ideal Home team have tested.

Founded in Italy in 2015, Vitesy has since solidified themselves as a leader in innovative air purificiation technology, prioritising sustainable and smart solutions to fight air pollution and even food waste. If you're thinking that the Vitesy name sounds familiar, it's probably because you've heard about their viral fridge purifier: the Shelfy.

Eteria is the brand's latest addition to their roster; a personal air purifier portable enough to be carried to and used in any space. Although its recommended room size is only a measly 15m², Vitesy have designed the purifier to move with the user throughout day to day tasks. They claim that the Eteria's compact and lightweight design makes it easy enough to take with you from room to room, creating a 'bubble of clean air around you' while you go about sleeping, working, studying, cooking, and more.

The Vitesy Eteria portable air purifier stands out from other models currently on the market as it has ditched the popular HEPA filter and has instead opted for the use of a photocatalytic, ceramic filter which (get this) doesn't need changing or replacing at all. Unlike HEPA filter replacements, which can set you back a couple hundred of pounds over a few years, you simply need to wash the ceramic filter under water to clean it, saving you money whilst being super sustainable.

But, does it actually work? I tested the Vitesy Eteria Portable Air Purifier in my own home for over five months to deliver my verdict on whether or not it's worth the purchase, and if the brand's high claims regarding the lack of filter replacements are exactly as they say.

How I tested

Assembly and set up

The Vitesy Eteria Portable Air Purifier arrived in a small, compact cardboard box, and assembly is super easy and straightforward. It's comprised of three parts: the main purifying unit, the monitoring module, and the cable.

The unit comes in a high-quality dust bag and the smaller parts tucked in a neat cardboard box with instruction manuals. Simply unbox each part and attach the purifying unit to the monitoring module, following the manual for guidance.

They should click into place intuitively via a magnetic connector. This ensures everything stays together securely whilst also allowing for flexibility if you wish to remove the main unit, take it with you, and attach it to another module that you might have placed in another room, for example.

To set up your air purifier, you need to download the Vitesy Hub app. Once you've downloaded the app, you can complete the set up process, which includes connecting your device to Wi-Fi, naming your device, and choosing your preferred settings. This is also where you can select your desired mode, brightness of the LEDs, and track air quality data through in-depth graphs. The Vitesy Eteria can also be connected to digital assistants like Google Home and Amazon Alexa to allow you to keep track of air quality hands-free.

Unfortunately, the Vitesy Eteria Portable Air Purifier can't be used without first being set up to the app, which can be either a positive or negative depending on your preferences. As someone whose whole house is set up on a Smart system, I didn't mind it at all as all of my home tech is controlled from my phone. However, I understand how this can be frustrating if you prefer to control your device using on-board controls – or at least have the option to do so. The Eteria has zero on-board controls in sight.

Design

The Vitesy Eteria Portable Air Purifier is, suffice to say, extremely stylish and minimalistic in its design. It's certainly a far cry from its bulky and unappealing air purifier counterparts.

At the time of writing, Vitesy offer the Eteria in two colourways: white and black. I chose white as it best aligned with my personal design preferences, and I wasn't disappointed when it arrived on my doorstep. The fabric filter is a light grey colour, and it has a light teal tab at the top of the unit, which acts as a carrying handle when you're bringing it from room to room.

The fabric filter can be washed and is removable to allow access to the ceramic filter when it's time for maintenance, which Vitesy recommend doing every two months or so to ensure maximum effectiveness; but more on that later.

The monitoring module is also very sleek, and extremely compact. When the air purifier is set up, it emits a white LED light, which changes to a slight orange colour to alert you of any present air quality issues. The brightness of this LED light can be configured in the Vitesy Hub app.

Performance

The Vitesy Eteria Portable Air Purifier offers six different modes, covering a wide range of fan speeds. This includes: Auto, Silence, Standard, Performance, Custom, and Timer.

When using the Auto mode, the air purifier will use its built-in sensors to adjust the fan speed automatically based on air quality in any given moment. For example, if the Eteria detects bad air quality, the fan will automatically adjust to the highest fan speed until the room's air quality returns to normal levels. In the Vitesy Hub app, the air quality levels are set at 'poor', 'good', and 'perfect'. When the air quality is the latter two, it'll simply stay in its Auto standby mode – which I can best compare to its Silence mode.

To test how effectively the Vitesy Eteria can pick up on changes in air quality in Auto mode, I lit a match close the air purifier and let it burn out to create smoke in the air. It took the Vitesy Eteria 21 seconds to register the smoke particles and for the indicator light to change to that red-orange tint I mentioned earlier, thus, bringing the fan speed up a few levels to tackle the smoke pollutants. It then took an additional two minutes and 41 seconds for the Vitesy Eteria to clear the air return to 'good' air quality.

When I left and returned to the room, my nose could still pick up traces of the remaining odour caused by the smoke, and it took over 10 minutes for the slight scent to dissipate completely.

I got better results when I tested how the Vitesy Eteria would react to me spraying aerosol deodorant in its vicinity. It took 15 seconds for it to register the VOCs present in the deodorant, knocking the air quality to 'poor' and amping up the fan speed to work on extracting these pollutants. It took the Eteria two minutes and 30 seconds to return the air quality back to 'good', bringing the air purifier back to its standby mode.

Even after the air quality had returned to 'good', I could still detect a faint deodorant odour in the air when I left and re-entered the room, but nothing that could be dubbed a deal breaker as this cleared quicker than the remaining smoke traces from the previous test.

I also tested the Vitesy Eteria in the kitchen to see how it fared with cooking odours. I live in a newly renovated home, so the extractor fan is still in good condition and does its job fairly well, so I was keen to see how the air purifier would perform in comparison. I've also got my MeacoDry Arete Two Dehumidifier & Air Purifier positioned in my living room, opposite one of my kitchen entrances, which I switch to its purifying mode every now and then to tackle strong cooking smells.

To complete the test, I shut the kitchen door, made sure my singular window was closed, left the extractor fan off and started frying two rashers of bacon, with the Vitesy Eteria positioned on the worktop next to my hob in Auto mode. Disappointingly, the Eteria never detected a change in air quality, despite the kitchen clearly being filled with cooking smells, so it never amped up the fan speed to counter it.

Despite that section of the test being a slight fail, I decided to just manually change it to Performance mode after the bacon was done cooking, assembled my bacon butty, and left the kitchen, closing the door behind me. I allowed 10 minutes to pass before returning where the loud Performance mode was working overtime. The scent was still slightly detectable, but had definitely minimised since switching it to the suitable mode. However, since the air purifier never detected the change in air quality, the app stated that the room was still 'good' even through my bacon trials.

In short, my extractor fan and the purifying mode on my MeacoDry Arete Two are significantly more effective at extracting cooking fumes and smells. I've been using my Vitesy Eteria primarily in my bedroom and home office over the months I've been testing it anyway, and I think it's far better suited for this sort of environment of general day-to-day air purification. I don't think the kitchen is where it best thrives.

If dealing with cooking fumes is a top priority for you when buying an air purifier, I'd instead recommend taking a look at the Philips 3000i Series, the Blueair Blue Max 3250i, and the AEG AX91-604GY Connected Air Purifier. These devices effectively picked up on the change in air quality and all averaged around 11 minutes to bring air quality back to 'good'.

Ease of use

As far as ease of use goes with the Vitesy Eteria, all of it pretty much relies on the use of their app – which as I mentioned earlier, can either be a positive or negative depending on how you feel about Smart tech and relying on tech to control your devices. There are zero on-board controls on the Eteria, meaning that it's basically non-functional without the use of the app.

I've personally not had too many issues with this way of control, as the Vitesy Hub is pretty responsive and intuitive to use for the most part. The only glaring issues I've had is when my Wi-Fi connection isn't great, as it doesn't register you choosing another mode due to poor connectivity. While this is quite subjective as Wi-Fi connection differs for everyone (and mine can be very jittery), it's annoying that something as simple as changing modes can be gatekept by this.

Therefore, I understand how this could be frustrating for someone who isn't all that keen on always needing their phone on them or wants to just quickly switch modes without having to pull their phone out or rely on Wi-Fi connectivity. For example, the Blueair Blue Max 3250i has both app and inconspicuous on-board controls, letting users choose their preferred method of use.

But, rest assured that when Wi-Fi isn't an issue, the Vitesy Hub app works well and switching modes is very simple. On the first page, you'll be met with your six options, which you can choose according to your preference. If you decide to use the Custom or Timer modes, you'll have to toggle a few more options to personalise them to how you want them, but the Auto, Silent, Standard, and Performance mode require no set-up and can be switched to with the click of a button. I keep mine on Auto and let it do its job, switching fan speeds according to environmental stimuli it encounters.

With the app, you're also given an insight into your tailored air quality data, which gives you an overview on the temperature, humidity, VOC, and CO2 levels in the room your air purifier is placed in. You can look at this data at a glance or its history over the course of a day, week, or month. As with any other apps, you can turn on notifications so you get alerts when the Eteria detects poor air quality, too, giving you even more control.

Noise levels

The Vitesy Eteria Portable Air Purifier can be very quiet in certain modes, with the brand claiming that sound levels measure between 30-52dB depending on the mode you choose – but in my own tests, I found it much louder than advertised in specific modes.

The quietest mode that still employs the use of the fan is the Silence mode, which I can only best describe as a very gentle whirring in the background. Thankfully, this quiet 30dB is what it defaults to when it's in Auto mode and hasn't detected any poor air quality. It's not distracting at all, and I can happily work in my office without feeling like it's imposing in any way. It really is what it says on the tin: silent. If anything, my laptop fan gets far louder when it's putting the work in!

However, I will say that while it's still on the quieter side, the Standard mode is notably louder and quite the jump up from the Silence mode. Even then, the sound level meter app I used on my phone still classifies this rough 48dB output as a 'quiet whisper'. I'm not particularly sensitive to sound, as I quite enjoy working along to white noise or background chatter; however, I can definitely see why just the Standard mode alone could be a distraction for those who are more sensitive to sound.

The Performance mode, however, was a complete shift. It's understandable that the air purifier requires a mode as such to eradicate strong pollutants, but its sound levels increased much higher than Vitesy advertise. According to my noise level meter app, the air purifier's sound levels were measured at a rough 65dB, which the meter app detected as being akin to a 'quiet street'. I understand that Performance mode is tailored to specific situations, such as being used in the kitchen to eliminate the smell of cooking odours, so it shouldn't really bother you in day to day life as it doesn't last long. But, it's still something to keep in mind.

That aside, the Silence and quietest end of the Auto mode are a pleasure when working or sleeping. Of course, when in Auto mode, the air purifier will detect poor air quality data and shift the fan levels up all the way to the loud Performance mode to manage indoor air quality accordingly. So, if you want no disturbances, simply keep the Eteria in Silence mode during night-time or in the middle of an important work meeting.

Portability

As air purifiers go, the Vitesy Eteria Portable Air Purifier is extremely lightweight and compact, coming in at only 1.25kg and measuring D16 x W24 x H16cm. This makes it the lightest air purifier we've tested at Ideal Home so far, even weighing less than the recently reviewed Blueair Blue Pure Mini Max, which weighs in at an equally impressive 1.4kg.

Considering the Vitesy Eteria's purpose is to be used as a 'personal' purifier that moves with the user, it only makes sense that portability was at the forefront of this device's design. The main purifying unit is attached to the monitoring module via a magnetic connector, allowing it to be picked up and moved easily. For this purpose, it also has a light teal coloured carrying handle at the top of the unit.

Since the Eteria is so small, it sits comfortably on the top of a dresser, bedside table, kitchen worktop, and more without looking bulky or out of place.

Energy use

The Vitesy Eteria Portable Air Purifier is very energy efficient, using just about 7.5W of power irrespective of what mode it's in. According to Vitesy, it consumes less than an LED bulb, giving you the confidence to keep it on for 24 hours a day without worrying about cost, allowing you to breathe clean air guilt-free.

It isn't quite as low as Blueair air purifier line, which starts at only 2W of energy at the lowest setting, but the Eteria still rounds out to costing less than 1p per hour to run – which is next to nothing compared to the higher average cost of running an air purifier.

Filter replacement

For the Vitesy Eteria Portable Air Purifier, the concept of filter replacement and maintenance is where it gets interesting, because there are zero filters to change. Unlike most air purifiers on the market, which use HEPA filters that require replacing every six months or so to keep the unit running at full efficiency, the Vitesy Eteria uses a photocatalytic, ceramic filter, in which its maintenance only requires being washed under running water to be good as new again.

To access the filter, you simply have to remove the fabric filter, then pull out the ceramic filter with its drawer. The fabric filter can be hand washed under running water or put in the washing machine at 60°C. The ceramic filter, on the other hand, just needs to be washed under running water and then left to dry. Just be sure that the both the fabric and ceramic filter are completely dry before reinserting. Vitesy recommend doing this every two months or so to ensure maximum effectiveness.

Since the Vitesy Eteria employs this reusable system, you effectively will never have to spend any additional money on buying replacement filters, as you would with models that require HEPA filters. This is a huge plus considering some of the more esteemed air purifiers on the market already come with a hefty price tag, and then you have to factor in the cost of buying filters over the months and years you use it. Not to mention, realistically speaking, a majority of people (myself included) will simply forgo cleaning an air purifier as regularly as they should be because of the extra effort and cost that comes with it.

With the Eteria, there are no hidden costs and what you pay for arrives complete. Sure, air purifier maintenance is every couple of months with the Eteria as opposed to the every six months schedule that comes with other HEPA filter air purifiers, but this isn't really a huge deal breaker for me as Vitesy have made it so easy to do.

Verdict

So, should you buy the Vitesy Eteria Portable Air Purifier? Overall, I was impressed with what this air purifier has to offer. It has fast response times, is lightweight and portable, and it costs almost nothing to run. Considering its compact size, it's definitely far more suited for smaller rooms like bedrooms and home offices, rather than used in open, communal spaces like living rooms and kitchens. Our testing process has shown that it's capable of quickly detecting a change in air quality as a result of the likes of smoke and VOCs, however, struggled when it came to dealing with cooking fumes.

Its portability and ease of maintenance is definitely its biggest draws, allowing you to slot it nicely on a worktop without making the space feel cluttered, move it from room to room as you wish, and save money on filter replacements in the long-run. Say goodbye to hardy maintenance, because the Vitesy Eteria is the easiest device I've had to maintain in a long time.

However, as mentioned, it's not without its drawbacks. While its Smart functions and Wi-Fi connectivity makes for a streamlined and easy to use device, its functionality is unfortunately gatekept behind the strength of your Wi-Fi connection. Without this connectivity, you'll struggle to make the most out of this air purifier. It's also louder than the brand advertise, with the Performance mode reaching up to 65dB, which can certainly be a distraction depending on where you're using it.

At its RRP of £189, it's definitely on the more premium side of the cost spectrum, and considering it lacks a little in dealing with cooking fumes and covers a really small area, it can feel like it's missing something. However, considering you can save a lot of money on not having to purchase filter replacements over the month and years you use it, the costs can even out in the long-run.

That said, I'll be continuing to use my Vitesy Eteria in my home office indefinitely, as it's ticked my personal boxes and more for personal purification in my small home office.

Air purifiers need to be turned on for a good chunk of time to improve indoor air quality, but it can be tricky to know whether you should leave your air purifier on all the time to get the most out of it. On the one hand, you want to breathe clean air consistently inside your homes, but on the other hand, you don't want your energy bills to be sky-high.

We asked the experts and the consensus is that while it is preferable to leave an air purifier running around the clock, it's not essential if you're concerned about running costs. Also, many of the best air purifiers now have an auto mode, so they switch themselves off when the air quality has reached a good enough level.

We asked the experts to clarify the situations when you should leave an air purifier running 24/7, and what you can do if you'd rather avoid your appliance running up the bills.

'Maintaining your indoor air quality is a priority, and leaving your air purifier on all the time is certainly beneficial,' says Joshua Warren, Air Purifier Expert at AO.com. 'These devices work by drawing in air, filtering out pollutants or allergens, then releasing clean air back into the room. Effectively, by leaving your appliance on all time, this means you’ll have the cleanest air possible - though this may cost you more in the long run.'

Because air purifiers are designed to continuously remove airborne contaminants - which don't simply stop occurring throughout the day - the general advice from manufacturers is to leave them running.

Some air purifiers can help with allergies, so if this is a primary motivation for using one, it's recommended to leave it running round the clock in order for it to be effective.

You can leave your air purifier on 24/7, and it is recommended to do so if you're using it to help with allergies. Air purifiers work by continuously filtering out airborne contaminants, including dust, pollen, allergens, and pollutants, and in order for them to consistently improve air quality, they need to be switched on.

Cost of leaving it on all the time

Fortunately, when it comes to how much air purifiers cost to run, many of them are relatively cheap. For example, the Blueair Blue Max 3250i - rated as the best all-round air purifier by the Ideal Home team - uses only 2W of energy on the lowest setting, and 20W on the highest.

'Our recommendation is to run your air purifier continuously to ensure efficient air circulation and low pollutant levels in your room,' says Lars Dunberger, Head of Technology, Blueair. 'Blueair air purifiers are energy efficient and very silent on the lowest speed level so you can keep them on and enjoy breathing clean air.'

If you don't want to leave it on all the time

That being said, your air purifier will still be able to significantly improve the air quality in a room if it's switched on for extended periods of time, especially in smaller rooms. One of the things to know before you buy an air purifier is the recommended room size; if it's capable of cleaning the air of bigger rooms, it doesn't necessarily need to be switched on all day to be effective.

'Generally, an air purifier requires several hours to noticeably improve the air quality in a room,' Joshua from AO.com says. 'For spaces with average levels of dust and allergens, running the purifier for about 8 to 12 hours daily can effectively maintain cleaner air. However, if you live in a highly polluted area or suffer from allergies, continuous use may provide greater benefits.'

'I recommend running it for between 12 hours and 24 hours a day,' Nicholas Auckland, Heating and Energy Expert, Trade Radiators adds. 'Of course, it all depends on the type of air purifier you have, the amount of pollutants you believe are in the air of your home, how you're affected by air based pollutants, and the size of your home/the room that the air purifier is in.'

It's also worth mentioning that it's only really necessary to leave your air purifier running if the room is being used at the time. While it's nice to maintain clean air in rooms even when they're empty, it's more economical to use your air purifier when you're going to actually experience its benefits.

The final alternative is to let the air purifier do the work for you and invest in a more advanced model with an Auto mode, which handily detects when the air quality has reached a good enough level for the purifier to switch off. This takes the guesswork out of how long you should leave the machine running for.

FAQs

Do air purifiers use a lot of electricity?

Many modern air purifiers are designed with energy efficiency in mind. They often come with a low fan setting, which can use as little as 2W of energy per hour - such as the Blueair Blue Pure 511 Air Purifier. To know how much an air purifier will cost to run, always check the wattage before you buy - less energy-efficient models may use 100W of energy per hour, which is soon going to add up if you're leaving it on all the time.

'With the current electricity price in the UK at 24.50 pence per kW, an air purifier that runs at 50 watts would cost just 29p a day to run for 24 hours, and around £8.70 a month,' explains Nicholas Auckland, Heating and Energy Expert, Trade Radiators. 'If you ran this air purifier every day of the year, then it would cost around £105.85 per year.'

When the Blueair Blue Pure Mini Max Air Purifier crossed my desk I was instantly intrigued. Blueair is a major player in the air purifier market and is regularly awarded the title of best air purifier. The new 'mini' version is the brand's most compact and affordable air purifier to date, so I was keen to find out if it could deliver the same impressive results as the Blue Max 3260i Air Purifier currently residing in the top spot of our air purifier buying guide.

Air purifiers are designed to cleanse our homes of airborne contaminants, including smoke, dust, pollen, pet fluff, and even Volatile Organic Compounds (VOCs), which can come from numerous household items. However, they can be bulky so a mini version featuring Blueair technology to clean the air sounds like a dream come true for small homes.

I put the Mini Max Air Purifier through a series of tests used on all the air purifiers we test at Ideal Home, and also used it every day for two weeks to see if this mini air purifier could deliver big results.

How I tested

Unboxing

Because of its compact size, the Mini Max Air Purifier is super lightweight and easy to carry around. The packaging is mostly recyclable, though there was a couple of pieces of single-use plastic in the box. Not a huge deal, but given that Blueair is a B-corp brand with a focus on sustainability, it would have been nice to see only recyclable materials in the box.

Assembly and set up

If you prefer low-fuss and easy to use devices, you'll likely be a fan of the Blueair Pure Mini Max Air Purifier. There's no assembly involved, simply remove the machine from its packaging, attach the correct plug, and it's ready to use.

Design

I love the design of the Blue Mini Max Air Purifier, Blue air has carried the design of its other air purifiers through into this mini version. With a height of 29cm, it's small enough to sit on top of surfaces without looking like an eyesore, thanks to its sleek aesthetic. I've got quite used to how it looks on my desk, and it's about as attractive as air purifiers can get.

Like its larger predecessor, the Mini Max Purifier comes with a removable fabric knit cover which is available in two colourways. The Stockholm Fog that comes as standard is a simple, neutral grey that's unlikely to clash with any decor, but you can purchase the cover in Limestone Beige if you prefer.

The control panel lets you turn the device on and adjust the fan setting, which can be set to low, medium or high. There aren't any Smart features, meaning there's no option to control the purifier using your phone or voice-activated devices.

Though the Mini Max Purifier is super easy to use, it's lacking in any advanced features. There aren't any modes to switch between, and there's no visual display showing the air quality, meaning it's difficult to know how effective the machine actually is. The top-rated Blue Max 3250i Air Purifier from Blueair has a light that changes colour in line with the air quality, so it would have been nice to see this on the Mini version as well.

Performance

The Mini Max is Blueair's most affordable air purifier yet, which does mean that it's pretty basic in its functions. As mentioned, there is no air quality indicator light, so it's difficult to have a clear measure of how quickly the device is cleaning the air. This meant that when testing the Mini Max - following the tests laid out in our guide to how we test air purifiers - I had to rely on my sense of smell to decipher how well the device was performing.

The Mini Max also lacks an automatic mode, whereby air purifiers adjust their fan speed based on the air quality in the room. This means that it's up to you to manually adjust the fan setting. An Auto mode is preferrable, because it takes the guesswork out of using an air purifier; the machine simply increases its fan speed whenever it registers a dip in air quality.

Unfortunately we can't rely on our noses to detect this dip, as many airborne pollutants are odourless.

That being said, I was able to get a good idea of how well the Mini Max can remove smoke from the room, given that smoke is pretty easy to detect with our noses. After using a match to light a candle next to the air purifier, I left the device running on the high setting and shut the door.

It only took around 7 minutes for the smell of smoke to fully dissipate. I thought this was pretty impressive for a smaller, budget-friendly air purifier, given that more powerful devices like the AEG Connected Air Purifier take around 4 and a half minutes to return the air quality to normal. I also performed the match test with the device running on the lowest fan setting, where it took around 20 minutes to get rid of the smokey smell - not bad considering the Mini Max only uses 2W of energy on this setting.

It was a similar story when I sprayed aerosol deodorant in the vicinity of the Mini Max, to test how well it could remove VOCs. After spraying the deodorant, I set the air purifier to high, closed the door of the room, and in just under 10 minutes, the smell had pretty much vanished.

The last test I performed with the Pure Mini Max Air Purifier was the bacon test. I popped two rashers of bacon on the hob and let them sizzle away while I plugged the air purifier in. When they were finished, I set the fan to high and left the kitchen to enjoy my bacon bagel, closing the door behind me.

I was super impressed with how quickly the Mini Max performed here. Before I switched it on, the kitchen was the full of the very distinct smell of frying bacon, but in less than 10 minutes, the scent had gone. For such a small machine, the Blueair Blue Pure Mini Max Air Purifier packs a pretty powerful punch.

Ease of use

The Mini Max's limited functionality is a shame, but this does mean that it's really easy to use. With only two buttons on the control panel, it would be difficult to not get the air purifier running smoothly.

I also like how there's a light to indicate what fan speed the machine is running on, though this does only show when you tap the fan button - it would have been nice to see the speed at a glance.

The buttons are touch-sensitive, so they only need to be tapped rather than pressed. Sometimes I did have to tap them a couple of times in order for them to respond, but this wasn't a major inconvenience.

Noise levels

On the low fan setting, the Pure Mini Max Air Purifier is so quiet I struggled to know that it was even on; only when I put my ear next to the machine could I hear the gentle whirring. This makes it perfect for those of us that prefer quiet home appliances, and even on the medium setting, the volume isn't loud or distracting.

On the high setting, the Mini Max does amp up a fair bit, and I didn't use this setting when working from home or watching TV. But the sound itself isn't annoying, and I didn't mind using the high setting when performing the match or bacon tests - the louder volume was a good indication that the machine was working hard to remove the smells.

Portability

As its name suggests, the Blueair Blue Pure Mini Max Air Purifier was designed for portability. It's the brand's most compact air purifier yet - smaller even that the Blue Pure 511 Air Purifier which we put to the test earlier this year - meaning it's perfect for keeping on top of bedside cabinets, tables, or desks (where mine is currently living).

With a weight of just 1.4kg, you'll have no trouble carrying it around, and its compact size means that it never makes a space feel overcrowded or cluttered. So while it lacks an Auto mode and air quality light display, it does tick all the boxes for someone that's looking for a small, budget-friendly air purifier.

Energy use

Fortunately, the Blueair Blue Pure Mini Max is super cheap to run. Using only 2W of energy on the lowest setting, and 10W on the highest, it costs less than 1p to run per hour. In terms of the average cost to run an air purifier, the Mini Max is at the lower end.

The only downside is that because the Mini Max doesn't have an automatic mode, it won't automatically switch off when the air quality has reached an acceptable level. You'll also need to manually change the settings between low, medium, and high, meaning you may wind up having it running on high more than if there was an Auto mode to decide for you.

Though leaving the device on for long periods of time will start to add up, the Mini Max is still considered a cheap appliance to run.

Filter replacement

Given that the Mini Max's affordability is one of its big selling points, it's worth remembering the ongoing cost of replacement filters after you buy, as with any air purifier.

The HEPA filters have a lifetime of 6 months, after which point it's recommended to replace them in order for the air purifier to keep working efficiently. No purifier is going to cleanse the air very well if its filter is clogged, and the Blue Pure Mini Max is no exception. Replacement filters are available to buy at £18, which is nice and affordable compared to a lot of other air purifiers - Blueair's second most affordable model (the Pure 511) has replacement filters that cost £25.

The fabric knit cover also acts as a pre-filter, trapping larger particles of dust before they can reach the HEPA filter. This doesn't need to be replaced, because it is washable, which makes maintaining the Mini Max nice and easy.

Verdict

Overall, the Blueair Blue Pure Mini Max Air Purifier is an affordable, easy to use device that gets the job done. Our testing process has shown that it's more than capable at removing smells from the air, at an impressive rate for a machine of its size. One of its best features is its portability, which aside from making it easy to carry around, means it can sit on top of surfaces without making the space feel cluttered.

But, there are some drawbacks - mainly that it doesn't have an air quality indicator, so there's no real way to tell how much the air quality is improving while it's on. This also means that the Mini Max lacks an Auto mode, so it won't automatically amp up the power when the air quality dips. This could be a dealbreaker if you're someone who would prefer an air purifier that takes the guesswork of how hard it should be working.

With 3 fan settings of low, medium and high, the Mini Max offers pretty basic functionality compared to other air purifiers on the market, including Blueair's more advanced models like the Blue Max 3260i and Dust Magnet 5440i. But this does mean that the Mini Max has a compact, lightweight design, as well as an affordable price point.

I'd say it's a good option for anyone that wants to improve their home's air quality, without splashing out on a fancy machine.

If you've taken the time to research and invest in an air purifier, it only makes sense that you want to ensure it's working as effectively as possible. As with many appliances, an often-overlooked factor to how well it'll work is placement. So, are air purifiers better on the floor or on a desk?

Although matters like this might seem trivial, even the best air purifiers' ability to clean the air effectively can ultimately boil down to where you've decided to position it. If you're finding yourself underwhelmed with your air purifier's performance, it's worth taking a moment to assess if placement could be the issue at hand; as this is one of the biggest things you should know before buying an air purifier.

To ensure you can wholeheartedly justify the value of an air purifier in your home, we've asked experts to explain why placement matters, location factors to consider, and whether situating your device on the floor, desk, or worktop is the best option for you.

Are air purifiers better on the floor or a desk?

'Air purifier placement depends on the unit's size, capacity, and features,' begins Michael Forbes, lead product trainer at AEG. As such, you should first consider the type of air purifier you have and the room you're planning to operate it in.

'Larger purifiers for bigger spaces are most effective when placed on the floor, where they can capture dust and particles that settle low,' says Michael. This includes heavier airborne particles such as pet dander, which is ideal if you're using an air purifier to help with allergies. This makes floor placement a more favourable option if you're dealing with air quality issues that require a bit more attention.

Lars Dunberger, head of technology at Blueair also adds that placing an air purifier on the floor 'promotes better air circulation and coverage,' making it a fantastic overall setup for keeping the space feeling as fresh and comfortable as possible.

On the other hand, Michael explains that 'smaller, personal units work better on a desk or elevated surface, targeting the air you breathe directly.' So, if you've got a compact model to combat minor air quality issues, these units are actually just fine on your bedside table, if you're using an air purifier to help you sleep better, or want one that fits snugly on your desk in a home office setup.

However, aside from the above circumstances, as a general rule of thumb it's typically more advantageous to place your air purifier on the floor if your unit allows for it to get the biggest bang for your buck.

Joshua Warren, AO.com's air purifier expert explains that is because 'placing your air purifier on a desk can limit its ability to draw in air from a large area, and while it may be suitable for small rooms, it will struggle to cover bigger spaces or non-confined areas.'

Irrespective of where you decide to position your air purifier, Lars says that 'ensuring proper clearance around the unit, regardless of placement, is key to optimising its performance.' When figuring out where to put an air purifier, you should always prioritise the rooms where you spend the most time.

'Most of us spend a third of our 24-hour day in the bedroom so if I had to recommend one room to locate your air purifier then it would be the bedroom,' advises Lars.

Alternatively, if your budget allows for it and your needs require it, you could even consider purchasing multiple air purifiers for different rooms. But of course, it's best to start off with one high-quality model and assessing from there if you'd benefit from another.

So, are air purifiers better on the floor or a desk? It depends on your air purification needs. If your home has more moderate issues with allergens, dust, and pet dander, and you're looking for a solution for a larger room, floor placement is the way to go. However, if you have a smaller model and plan to operate it in a small bedroom or office, it's possible that placing it on a desk or raised surface will make the most sense. But, when in doubt, the floor is generally the best way forward for maximum efficiency.

Whichever you choose, ensure it's got enough air circulation to keep it working as efficiently as possible. With the right placement, you can rest assured that you're curating a cleaner and more comfortable environment throughout your home.

Our homes are bombarded with smells every single day. From cooking smells to wet dog smells, they’re not pleasant. But trying to eliminate these can also be difficult, even with regular cleaning, so you might wonder: do air purifiers remove smells?

Of course, the best air purifiers are a must-have when you want to clean and filter the air inside your home. These handy appliances capture dust, allergens and other airborne pollutants, but smells can linger even in the cleanest of homes. And most people don’t realise that an air purifier can help here, too.

The short answer is yes, an air purifier can remove smells. But there are a few caveats to this, as an air purifier’s ability to get rid of odours all depends on the type of air purifier and how you use it. So, this is what you need to know.

Some air purifiers can remove smells, and it's one of the unexpected perks of these appliances, but it depends on the type of purifier you have. 'Air purifiers are not only capable of effectively removing airborne particles such as dust, pollen, and bacteria, but certain purifiers can also tackle unpleasant odours in your living space as well,' begins Michael Forbes, lead product trainer at AEG.

'If you are wondering how to remove odours, volatile organic compounds (VOCs) or gases from household chemicals and other sources from the air at home, consider an air purifier with an activated carbon filter,' advises Lars Dunberger, head of technology at Blueair.

That’s because there are many different types of air purifiers, and they are all equipped with different filters designed for different uses. The activated carbon filter, in particular, is ideal for odour removal.

Chris Michael, managing director at Meaco explains that this is because 'activated carbon is effective at absorbing odours from pets, cooking, and other household sources by trapping gas particles in the filter. Gas particles are too small to be captured by HEPA filters, so for smells, a carbon filter is the way to go.'

According to Michael, these activated carbon filters work by trapping odour molecules on their surface, neutralising them, and removing them from the air. 'Combine that with reducing exposure and your home will smell as fresh as it looks – and have cleaner, healthier air,' continues Lars.

This is one of the many things you should know before buying an air purifier, as buying an air purifier without this filter will make odour removal much less effective. However, they may still work for subtler smells.

Michael explains that HEPA filters can help air purifiers to remove smells, even though they’re not specifically designed for odour elimination. This is because they capture the airborne particles actually causing the odours. Combined, this filter duo makes for a fantastic air-purifying experience.

'High Efficiency Particulate Air (HEPA) filters are excellent at capturing dust, pollen and smoke. When these are paired with activated carbon fibres which are specifically designed to absorb odours and gases, this gives you best chance in removing smells using an air purifier,' agrees Joshua Warren, air purifier expert at AO.com.

But it's not just the filter type you need to think about. 'Another key factor to consider when looking to remove odours from a space is ensuring the purifier is appropriate for the room size, so you achieve the best performance at efficiently removing odours,' adds Michael.

In some cases, you might need multiple air purifiers to tackle each affected area in your home. Often, a singular model cannot be a one-size-fits-all solution if you've got moderate to severe air quality and odour issues.

It's also important to combine the investment of an air purifier with frequent cleaning practices, as failing to tackle the root cause of a smell - for example, a smelly drain or rotten food - will mean that your air purifier is constantly fighting a losing battle.

Plus, you need to regularly clean or replace your air purifier filter to ensure it’s working to the best of its ability.

So, do air purifiers remove smells? Yes they do, but only if you choose the right one. Air purifiers with activated carbon filters are your best bet for tackling unpleasant odours inside your home, and combined with a HEPA filter, you're well on your way to achieving the best possible outcome for your indoor air quality.

Knowing how to clean an air purifier is essential for keeping these handy devices working optimally. A clean air purifier means cleaner air and a cleaner home, which means you'll be getting the most out of your device when you use it.

The best air purifiers improve our indoor air quality without issue. They remove unwanted contaminants from our environment, including dust, pollen, and pet dander, and ideally, they run quietly and don't look like an eyesore.

While air purifiers can remove dust - and capably so - it gets pretty hard for them to do this when they're covered in dust themselves. Running these devices when they're dirty becomes almost pointless, which is why taking the time to learn how to clean an air purifier properly is essential.

Fortunately, it's pretty easy to clean your air purifier once you know how. Just like cleaning a dehumidifier, all you need is a few simple cleaning supplies to get your device working at its best again.

We've asked the experts how to clean an air purifier and compiled all their top tips into this handy step-by-step guide. Note that to keep your machine working optimally, you should be cleaning it every couple of weeks.

Why is it important to clean an air purifier?

If you use your air purifier frequently, it's important to keep on top of cleaning it. 'A dirty air purifier can lead to reduced efficiency, because pollutants will be able to bypass clogged filters,' says Nathan Paul, Air Appliance Expert, Appliances Direct. 'The machine will have to work harder to push air through dirty filters, and its efficiency will be seriously reduced.'

Given that we use air purifiers to cleanse our environment, it would be counter-productive to use one if it wasn't clean itself. In fact, experts warn that aside from not cleaning the air properly, dirty air purifiers can actually make things worse.

'There could be certain health risks if you continue to use your air purifier without cleaning it,' says Nathan explains. 'Mould, bacteria, and allergens trapped in dirty filters may circulate back into the air. Plus, dust buildup can cause louder operation and even overheat the unit.'

What you'll need

Now we know why it's important to learn how to clean an air purifier, we can get into the nitty gritty of how it's done. First, you'll need to make sure you have the following:

• Multi-purpose cloths - these eco-friendly ones from Seep are perfect, £9.50 for a pack of 3 on Amazon
• Mild cleaning solution, such as this one for £4 from Amazon
• Spray bottle, like this pack of 2 for £5.99 on Amazon
• Warm, soapy water
• Vacuum with a soft brush attachment
• Cotton buds
• Rubbing alcohol, like this £5.80 bottle from Amazon

Step-by-step

1. Unplug and dismantle your air purifier

First thing's first, you'll need to unplug your air purifier before you start cleaning it. After that, start to dismantle the device by taking apart the removable components. These can differ from model to model, but they usually consist of a pre-filter, HEPA filter, and carbon filter.

It's handy to have a copy of the user manual - physical or digital - with you at this stage, so you can see what parts your machine is made up of. Nathan from Appliances Direct says the key components to focus on when learning how to clean an air purifier are:

• Exterior casing: dust and grime tend to accumulate on the outside of the device.
• Pre-filter: designed to capture larger particles like pet hair and dust, this filter is often washable.
• HEPA and carbon filters: these catch finer particles and pollutants, and need special care.

As you remove the different components, make a mental note of where they all go, so you remember how to slot them back into the device at the end.

2. Clean the exterior

With your cleaning cloth, start to wipe down the exterior of the air purifier. Dust can often collect on the surface of the device and find its way into vents and crevices, which is a common cause of air purifiers not working.

'Use a soft, damp cloth to wipe down the exterior of your air purifier,' says Joshua Warren, Air Purifier Expert, AO.com. 'Avoid using any harsh chemicals and use a soft brush or vacuum to gently remove any build-up of dust and debris from the purifier’s grills.'

'For stubborn dirt, you can use a mild detergent diluted in water, but avoid harsh chemicals like bleach or alcohol, as they may damage the material,' Nathan says. 'And be careful not to let any moisture seep into the internal parts of the purifier.'

We recommend diluting your mild cleaning solution even further, by mixing it in a spray bottle with some water. This means you can use as much as you need to in the cleaning process, without risking any damage to the machine.

3. Clean the pre-filter

Most pre-filters that come with air purifiers are washable. The pre-filter is usually a mesh panel that acts as the first stage of the purification process, by trapping large particles and debris.

To clean this, soak it in warm, soapy water, and gently scrub the surface to remove any dust and dirt. Avoid using any harsh brushes or scourers, as this could damage the panelling.

'Make sure to let it air dry completely before reinserting it into the unit, as moisture left in the filter can damage the device or promote mould growth,' Nathan says.

4. Clean the HEPA (or carbon) filter

HEPA (High Efficiency Particulate Air) filters are amazing for removing unwanted airborne particles, and the best air purifiers usually have one - including one of our tried and tested favourites, the Levoit Core 300S air purifier.

'Gently vacuum the surface of the HEPA filter using a vacuum cleaner with a soft brush attachment, to remove dust and debris,' Nathan advises. 'Avoid pressing too hard as you could damage the delicate fibres.'

If your air purifier has a carbon filter instead of a HEPA, you can clean this with the same method. Both types of filters will need to replaced eventually, even when you keep on top of cleaning them.

'In general, HEPA filters require replacing every 6-12 months, and carbon filters need replacing every 3-6 months,' Jason DiBona, CEO of Molekule says.

5. Clean the sensor

'Many air purifiers come equipped with an air quality sensor that measures pollutant levels,' Nathan from Appliances Direct explains. 'A dirty sensor can lead to inaccurate readings and poor performance.'

The air quality sensor is usually located near the air intake. To clean this, simply dip a cotton bud in a small amount of rubbing alcohol and wipe the sensor with it carefully. This will disinfect the sensor and allow it to continue performing optimally.

6. Reassemble and test

Once you've cleaned all of the purifier's components, you can reassemble the device and plug it back in. Make sure you put all the different parts back in their correct places - they should slot back in easily, without the need for force.

'Check to ensure it’s working properly and that airflow is unobstructed,' Nathan says. 'If the purifier was noisy before, you should notice a quieter operation post-cleaning.'

FAQs

Can air purifier filters be washed?

'Most HEPA filters are non-washable, as washing them can damage the fibres and ultimately make them less effective at trapping particles,' Joshua says. 'It’s a good idea to replace your filter once you’ve noticed that it’s either damaged or well used.'

While it's not advised to wash your HEPA filter, you can keep this clean with the soft brush attachment of a vacuum. This will remove dust and debris, and keep the filter working efficiently. Note that they should still be replaced every 6-12 months.

'However, many pre-filters, which are used to catch large particles like dust and pet hair, can be washed,' Joshua adds. 'Try to rinse yours gently with water and let them fully dry before placing them back in the purifier.'

What happens if you don't clean your air purifier filter?

'Neglecting your air purifier is not a good idea and can end up costing you time and money,' Joshua from AO.com explains. 'The strain this puts on your appliance can end up shortening its lifespan, because the components will wear out much faster.'

As the filter is responsible for removing dust and unwanted particles from the air, if this isn't cleaned regularly, it simply won't be able to this. Essentially, there would be no point using your air purifier, as the device wouldn't be able to clean the air effectively.

Now you know how to clean an air purifier - and why you should definitely be doing so - you can continue using your device and enjoy a cleaner, fresher home.

Air purifiers and air filters both share the same goal to remove pollutants and clean indoor air; however, they each work in different ways altogether and offer slightly different results.

When looking for solutions to improve the air quality inside your home, the best air purifiers are more often than not the first thing to spring to mind. Engineered to filter out all sorts of smaller particles like allergens, dust, pet dander, and more, these little plug and play devices have made it easier than ever to manage and monitor indoor air quality.

However, when looking at all the different ways to reduce allergens at home, you might have come across another air treatment solution: an air filter. These, on the other hand, are designed to remove larger pollutants and other airborne contaminants from the air.

So, what exactly is the difference between the two and which one is the better fit for your home?

Air purifier vs air filter: what is the difference?

Typically speaking, Chris Michael, Meaco's managing director explains that air filters are used more so in HVAC systems in commercial settings where there are more vents in place and ducting in the ceilings and walls, such as in shopping centres, leisure centres, hospitals, etc.

'In a home context, an air filter would be used inside an appliance of some kind that involves air treatment. For instance, an air purifier will use a HEPA air filter, a dehumidifier uses a dust filter, as does a vacuum cleaner, and so on,' continues Chris.

However, to keep things simple, we're focusing on broad air filters found in both domestic and commercial settings, as explained by Chris above.

'An air filter is a device composed of porous materials that remove particulates, such as smoke, dust, and mould from the air. It is particularly used in homes and cars,' explains James Longley, managing director at Utility Bidder. 'The main function of an air filter in a home is to ensure the air circulates through your HVAC system and keeps your house clean.'

These filters trap unwanted elements that would otherwise float freely through the air. But, it's important to note that because air filters are more common in commercial settings where capturing bigger contaminants is most necessary, James notes that they're often not as effective against smaller particles such as pollen, dust, and dander.

In this case, this is where air purifiers become the choice most worth the investment if you want the most effective results.

'Unlike standard air filters, air purifiers are standalone devices that use multiple methods to remove smaller particles, odours, and allergens,' explains Iain Wareham, head of product line at AEG. 'Air purifiers often use HEPA (High-Efficiency Particulate Air) filters, which are highly effective at capturing tiny particles like dust and pollen.'

Air purifiers with HEPA filters are the ideal option if you're looking for an appliance to remove dust from your home to the best capability, capturing up to 99.7% of airborne particles. Iain adds that some air purifiers even take it a step further to combine HEPA filtration with other forms of filtration.

These different types of air purifiers feature filters that include, but are not limited to: ionic filters in the form of ionizers, which release negatively charged ions into the air and active carbon filter purifiers which use activated carbon to absorb gases and odours.

Which is better, an air filter or a purifier?

When debating between an air purifier or an air filter, there's no denying that air purifiers are the best choice for managing air quality inside a home over an air filter.

'Overall, most air purifiers are designed with a combination of technologies that allow them to provide a more comprehensive clean compared to standard air filters,' says Iain.

'Air filters can be low in cost and also disposable. However, they can get clogged quickly and may need to be replaced quickly. Air purifiers can be an expensive purchase, however, they can be very effective and do not need to replaced as regularly,' explains James.

And, if you are worried about cost, there's no need to fret as you can purchase some fairly affordable air purifiers to get started on your journey to cleaner air. To help you, here are some of our favourite models we've tried and tested.

All in all, not only are air purifiers easier to install and can be brought into any setting by simply being plugged in, but they're far more useful for tackling smaller airborne contaminants that our homes would be facing the most within day to day living – including pollen, dust, and pet dander. This, in turn, makes air purifiers a worthwhile investment if you have allergies or respiratory issues.

Generally speaking, our homes don't necessarily need air filters in the same way that commercial settings do, so improving your indoor air quality is best done through the use of an air purifier.

Our Dupray Bloom air purifier review puts one of the UK's newest air quality brand's best-selling models through its paces to see how it compares to the best air purifiers the Ideal Home team has tested.

Founded in Canada, Dupray now sells in the UK, with a large product range that includes the bestselling Bloom air purifier.

The Bloom features a modern design that seamlessly blends into your home decor, serving as not only a sleek-looking air purifier but also a planter or an accent side table with an oak or walnut table top and in-built storage, making it a super versatile piece of furniture, especially when space is at a premium. Plus its range of washable filters in various tonal colourways means you can match it to your home decor while keeping the HEPA filter in tip-top condition.

Equipped with a HEPA-13 medical-grade filtration system, it can capture 99.97% of airborne particles as small as 0.1 microns, filtering out dust, pollen, smoke, pet dander, bacteria, mould and even unpleasant odours.

It features nifty AutoDetect technology with infrared sensors to constantly monitor the air quality and the fan speed automatically adjusts to clean the air sufficiently, which is a massive plus for those with allergies or respiratory problems, as it means it doesn't require constant manual adjustments to be super effective.

Designed to purify larger spaces, it's suitable for rooms up to 141 m2 and the 360-degree air intake makes it an excellent choice for open-plan living areas as it ensures better air circulation, providing clean air throughout a room. I put it to the test to see how it performed in practice.

How I tested

Assembly and set up

Setting up the Dupray Bloom is a breeze. Once you unbox it, it's pretty much ready to use with minimal packaging to faff about with. Its notable advantage is that it's extremely lightweight over bulkier models that are hard to move about. On the back of the main body, a QR code provides easy access to setup instructions.

Once the basic set-up is done, it's ready to get up and running. It features a user-friendly air quality alert system that lights up in different colours to indicate air quality levels, and the air quality indicator fades out after 20 seconds for a subtle appearance.

You can choose from its three fan speeds, night more or just set to AutoDetect mode for adaptive air purification. Dupray says all you have to do with the Bloom is 'set it, and forget it' in Auto Detect mode for adaptive air purification so it doesn't come with an app.

The auto mode features an infrared sensor that monitors and detects air pollutants, without you having to do much at all, which suits me right down to the ground.

Design

The Dupray Bloom definitely has more style than your average spaceship-like design of others on the market. It blends seamlessly into the background as a planter and looks really quite good as an accent table with the wood tabletop.

It's not just a pretty face, though. Its smart features, ease of use, and quiet operation make it an all-rounder. With a HEPA-13 medical-grade filtration system, which is capable of removing 99.97% of airborne pollutants as small as 0.1 microns, it makes it ideal for large rooms and open-plan living areas.

I particularly like the removable fabric knit cover that encases the lower half of the air purifier which can be easily removed and washed. The cover isn't just for looks though, it also works as the air purifier's pre-filter, preventing large particles of dust and hair from entering the HEPA filter underneath.

The pre-filters come in 13 different colour options and I received the 'Latte' colour as a spare for the 'Cloudy Gray' which comes as standard. Both of which worked well with my home's colour schemes.

One of my other favourite parts of the design is the multi-functionality of the device. With its wood table top, available in oak or walnut, you can use it as a sleek-looking accent table to set a coffee on or as a bedside table.

Or if that doesn't fit with your living room scheme or bedroom look, then you can use it as a planter for a substantial, medium-sized houseplant it features a strainer for when you need to water your houseplant, and you can even plant it directly in the device.

Or if houseplants aren't your thing, the nine-litre planter area can be used as a convenient place to store or hide your remote control, a book or two, reading glasses - you name it.

The indicator button on the front automatically changes through three coloured lights to let you know the current air quality. Green means 'great' air quality, yellow 'good', and purple 'poor.'

The air quality indicator light is situated on the same button as the controls, making it super minimalist. Once it indicates the air quality level, the light fades again to blend into the body of the device.

I really like the design of the Dupray Bloom. It's stylish but simple so it fits seamlessly into whatever room it's placed in, and isn't an appliance you feel the need to hide away out of sight.

Performance

The Dupray Bloom air purifier offers three fan speeds that you can set manually, as well as a Night mode, and a game-changing Auto mode which means you can simply be hands-off and let the device do all the work.

When the AutoDetect setting is chosen it uses its in-built infrared sensor to adjust the fan speed automatically based on air quality. For example, if the air quality is poor, then the fan will automatically be set to high fan speed.

This is a great feature as it means you can save on energy by only using the fan speed necessary to clean the air, and this is the mode that I put the air purifier into to perform the first performance test.

When I first turned the purifier on it showed a yellow light on the indicator display, which means 'good' indoor air quality. A relief all around.

To test out whether it could pick up on changes to the air quality, I lit a candle close to the air purifier and blew it out to create smoke. In AutoDetect it took the Bloom seconds to register the smoke and for the indicator light to go purple.

The drop in the air quality meant it automatically increased the fan speed to return the air quality to 'good'.

It took roughly eight minutes for the Bloom to clear the air and return to standby, and when I left and returned to the room, I couldn't detect any smoke smell.

I also tested spraying an aerosol deodorant close to the air purifier. It took seconds for it to register the VOCs present in the deodorant, and the indicator light displayed purple for 'poor' air quality and soon got to work extracting.

This time the air purifier took longer to return to standby. I still noticed a faint odour of deodorant when I re-entered the room, but the purifier had made an obvious improvement to the air quality.

I also tested the Bloom in the kitchen after cooking to see how it coped with fumes. Our kitchen has a pretty useless extractor fan and we always find it hard to remove cooking smells, so I was curious to find out how the air purifier would improve that situation.

We put it to the test by shutting the kitchen door, making sure the windows were closed, leaving the extractor fan off and frying an egg whilst the Bloom was positioned in the dining area in AutoDetect mode.

From when the egg first started sizzling, it took the Bloom a few minutes to register the smell at which point it soon shifted the fan speed up as the fumes intensified.

Around a minute later the egg was cooked, so I made my egg on toast, left the kitchen, shut the door, and had my lunch while the Bloom got going to remove the fumes.

Once I'd had my lunch, after about 10 minutes I went back in to find the fan had stopped, and the Bloom had returned to standby, indicating it had cleared the air. There was barely any lingering cooking smell when I came back in and I have a nose like a bloodhound - impressive stuff.

Then, lastly, I performed the dust test. Whilst the Bloom was in its AutoDetect mode I emptied the contents of my vacuum cleaner onto the floor next to it. The air quality indicator did change to purple for 'poor' air quality, while the fan kicked up several gears. I was surprised that it detected so quickly.

I also manually set the air purifier to its highest fan speed and performed the same exercise. The dust particles were clearly being drawn towards the air purifier, and again the indicator light showed a decrease in air quality.

Overall, I was incredibly impressed by the Dupray Bloom air purifier's performance.

Ease of use

The performance of the Dupray Bloom air purifier really impressed me, and its ease of use could not be faulted.

It's an extremely easy-to-use bit of kit, without the need for an app with its incredibly responsive AutoDetect mode. You can just switch it to this automatic mode and it sets to work.

Noise levels

The Dupray Bloom air purifier is very quiet, measuring as low as 24dB depending on the fan speed you choose and it's its quietest while in night mode, which I tested in both my bedroom and my daughter's.

When it detects a change in air quality though, that's a different story. It gets loud when it's running in its highest fan speed which I found quite irritating while watching TV, otherwise, the low and middle fan speeds are relatively quiet.

Portability

As air purifiers go, the Bloom is super light, weighing in at 4.63kg and measuring H48 x W33 x D33cm, making it easy enough to pick up and move around the home. However, it does lack any handles or handholds, which would have been a nice addition to the design. You really need to have the ability to grip its cylindrical build with two hands.

It is on the large side so it's a good thing it's designed to sit at floor level.

Energy use

Compared to most air purifiers of this size, the Bloom air purifier is super energy efficient using just 2.5-20W of electricity depending on which mode you have it running in.

With the AutoDetect mode on, it means you don't need to have the purifier constantly running on a high fan setting. Instead, you can leave it in this mode and the air purifier will remain on its lowest setting unless it detects a drop in air quality. Then it will swing into action at a higher fan setting. A really nifty energy-saving measure.

Find out more about how much it costs to run an air purifier in our guide so you can compare the Bloom to the average energy usage.

Filter replacement

After you purchase the air purifier itself, you'll need to factor in the ongoing filter replacement and the cost associated.

Most manufacturers advise that an air filter should be replaced roughly every six months due to it becoming clogged up, compromising its efficiency.

Dupray advises similarly, recommending the Bloom's air filter be replaced every six to nine months.

The brand advises periodically cleaning the pre-filter with a soft brush attachment on a vacuum hose. Or for a deeper clean, you can easily wash the pre-filter.

When you do come to replace the filter, Dupray states Bloom's medical-grade HEPA-13 filter is made with 64% less plastic than the competitors' filters, making it the most affordable replacement HEPA-13, medical-grade filters on the market, at only £23.99 each, as of writing.

Verdict

Overall, I was incredibly impressed by the Dupray Bloom air purifier. It's extremely responsive to air quality changes which is a great addition to our old house.

Aside from its awesome performance, I could not fault its aesthetic appeal. Its simple, yet smart features like the AutoDetect, its ease of use, and quiet operation make it a standout choice for anyone who doesn't want to compromise on either functionality or design.

That AutoDetect mode also means the air purifier is never using more electricity than it needs to, while its replacement medical grade air filters are the most competitive price-wise than other options.

In fact, the only real niggle I had with the Bloom is that it's big. However, in terms of performance, usability and style, it's hard to fault this well-designed air purifier. Whether you’re dealing with allergies, poor air quality, or simply want to get rid of cooking fumes, the Dupray Bloom is an investment worth making.

Air purifiers are fast becoming an investment worth making, helping to improve indoor quality and remove pollutants and allergens from the air inside your home. However, if you've started to run into problems with yours, it's worth understanding what causes an air purifier to stop working.

The best air purifiers should last you a handful of years with proper care and maintenance, but as with any home tech investment, they will, unfortunately, need replacing when they're on their last legs.

But before you throw in the towel, it pays to know why your air purifier might be causing you issues to help you identify any future problems sooner and better widen your understanding of your investment. If you ask us, these are likely to crop up when considering things to know before buying an air purifier.

What causes an air purifier to stop working?

'The lifespan of a typical air purifier is between 5 to 10 years, which can vary depending on several factors, including frequency of use, maintenance and the quality of the device,' explains James Longley, managing director at Utility Bidder.

'It can be frustrating when your air purifier stops working, however, there are simple factors that could be the reason as to why it has stopped operating.'

So, here are 5 common reasons why your air purifier is not working.

1. Clogged filters

When asking yourself, 'Why is my air purifier not working?', Chris Michael, MD of Meaco explains that the main cause is the air filters becoming clogged with dust and particles.

'In this instance, the air purifier will not be able to function effectively,' he notes. 'Regular maintenance and filter replacements are crucial to prolong the life of the appliance. Most filters last between six months to a year.'

2. Insufficient airflow

For an air purifier to work effectively, sufficient airflow must be given to the device when considering where to place it in your home.

James explains that one of the potential reasons why an air purifier has stopped operating is a result of 'placing the device too close to a wall'. Similar to where not to put an air conditioner, you should avoid putting the air purifier in enclosed areas with little ventilation.

3. Faulty power supply

'It is also possible for the power cable to become damaged or loose which can stop the purifier working,' explains Nathan Paul, air appliance expert at Appliances Direct.

Seeing as air purifiers are used extremely frequently, the possibility that the power supply has become damaged over time is not entirely unlikely. 'While this is a rare occurrence, checking the power source and ensuring the cord is intact during use can resolve this issue,' adds Nathan.

As such, if you suspect that this might be the issue it may be worth purchasing a new cable or looking into a replacement.

4. Worn out fan motor

As we mentioned above, the appliance itself will eventually wear out with frequent use, too. 'Over a long period, the air purifier fan motor can wear out and become less effective, leading to reduced airflow and efficiency,' remarks Nathan.

This is why Lars Dunberger, head of technology at Blueair stresses the importance of prioritising quality when looking into choosing the best type of air purifier for you.

'Quality matters not just for the purifier itself but also for its components. Investing in high-quality filters not only ensures optimal performance and longevity but not replacing them with genuine filters can lead to frequent breakdowns and reduced air purification efficiency,' explains Lars.

On the topic of appliance malfunctions, Michael adds that a sign that it needs replacing is if you are starting to notice a smell from it – in which case, it's worth finding out why your air purifier smells.

5. Plastic sealing hasn't been removed

While all the reasons we've listed so far centre around an air purifier that has been used for some time, if your device is new but still isn't working, Lars suggests one simple check.

'Ensure that the plastic sealing has been properly removed from the filter inside the air purifier. This is a common oversight and something we advise all customers to check on their new devices.'

6. Irregular or overdue maintenance

Although air purifiers typically only require minimal maintenance, it's inevitable that with regular use, natural filter build-up will occur. Therefore, keeping on top of cleaning filters regularly and checking their overall function certainly pays.

'Cleaning the appliance's filter will put the appliance and its motor under less strain and prolong its efficiency and working life,' assures Nathan.

If you want to unclog your purifier yourself, James advises to 'simply turn off the device and unplug the purifier, you can then clean the filtered air outlet using a soft-bristled cleaning brush.'

FAQs

How long should an air purifier last?

Typically, the lifespan of an air purifier is between 5 to 10 years. However, this can vary and is dependent on factors such as frequency of use, quality of the device, and how often you're maintaining it.

Why would my air purifier stop working?

'One of the most common reasons your air purifier may stop working could be due to a bad filter. As your purifier cleans up your air, it forces air through a filter which traps particles, such as mould and pollen, and eventually, the filter will get clogged up and may then require a replacement,' explains James Longley at Utility Bidder.

Alternatively, other factors such as appliance malfunction and irregular maintenance and upkeep may also be common reasons why your air purifier stops working.

At the end of the day, ensuring you're on top of frequent checks of your home investments is the best way to prolong its lifespan and keep it working well for years to come.

'Every air purifier comes with a unique set of care instructions tailored to its specific design and components. Following these instructions carefully ensures that you are maintaining the purifier correctly,' concludes Lars from Blueair.

Levoit and Blueair are easily some of the most recognisable names in the air purifier world. However, when given the choice between the two, which one should you really buy?

As with any home investment, deciding on the best air purifier for you and your household is always best done on a case-by-case basis. However, among the many models we've tested here at Ideal Home, Levoit and Blueair are top-of-the-barrel regarding their capabilities for improving indoor air quality.

To help you better understand which type of air purifier is best for you in the ongoing Levoit vs Blueair debate, we've compiled all the basics and must-knows about these leading clean air brands to assist you in making your choice – as well as keep you from being blindsided on a handful of things to know before buying an air purifier.

Levoit vs Blueair air purifiers

Below, we've condensed the 'what to know' for both Levoit and Blueair, as well as our favourite air purifier models from each leading brand.

Levoit air purifiers: what you need to know

In case you didn't already know, Levoit is a brand that's ben lauded for its for clean air solutions, often associated with its companion brands COSORI (whom we praise for giving us some of the best air fryers we've tested) and Etekcity for other home wellness products.

Levoit boasts a wide selection of air purifiers with smart features, allowing you to control its settings from the comfort of a smartphone app or through voice assistants like Amazon Alexa or Google Assistant. This smart home trend got to show off its skills when we reviewed the Levoit Core 300S air purifier, which received a glowing 4.5 stars during testing.

The Core 300S has earned its place in our air purifier buying guide as being the best option for a smaller space. Whether it's to be used in a small bedroom or home office, this bestselling Levoit model is compact and easy to use making it a great choice for many people because of its unobstructive and sleek design. Better yet, it's super quiet (especially in sleep mode) making it the perfect addition to your nighttime routine.

Additionally, its HEPA and activated carbon filter make this the supreme choice if you're looking to purchase an air purifier to help with hay fever as these filters are the best for getting rid of dust in your home.

Coming in at an RRP of £154.99, we'd say that the Levoit Core 300S is priced relatively affordably given its smart features and capabilities – especially if you plan to use it in a small space. Otherwise, it might be worth taking a look at alternative larger options that'll work more effectively for treating air quality concerns in a bigger space.

Blueair air purifiers: what you need to know

Blueair is just one of the most reputable names among the many clean air companies on the market.

Undeniably, we're quite the fan of Blueair here at Ideal Home, having reviewed a handful of the brand's sought-after air purifiers including the bestselling Blueair Blue Max 3250i air purifier – which has cemented itself as the top choice overall for an air treatment investment – and the Blueair Blue Pure 511 air purifier which is our best budget buy for under £100.

Blueair's unique filter design allows it to catch at least 99.97% of airborne particles down to 0.1 micron in size, without so much as generating any unwanted noise or running up the cost of operating an air purifier and helping you save energy at home.

In our review, the Blue Max 3250i was dubbed a 'brilliant all-rounder' offering 'super-responsive performance, stylish good looks, and Wi-Fi connectivity' enabling the use of voice commands, similar to Levoit's sought-after models. With a HEPA filter and carbon sheet, Blueair's air purifiers are also a perfect choice if your main reason for purchasing an air purifier is to help with allergies.

However, one thing you ought to be aware of is that these Blueair models don't have a timer and are also on the smaller side, meaning you'd need multiple air purifiers to cater to different spaces (or, again, opt for alternative products for larger areas in your home).

Levoit vs Blueair: which is more affordable?

As we mentioned above, if affordability is the issue then the Blueair Blue Pure 511 is what we believe to be a fantastic budget option, available to purchase from as low as £89 at a handful of retailers.

Our reviewer noted that this smaller model offers a 'decent CADR for its size and price point', however, if you can afford to splurge a little more then we'd always recommend just waiting out for the Blue Max 3250i as it offers everything the Blue Pure 511 has and more for £50 more.

Levoit's pricing, on the other hand, is more comparable to the price of the Blue Max 3250i with both the bestselling Levoit and Blueair products sitting in the £140-150 range. But again, both choices are equipped with great features that make them worth the price tag.

Levoit vs Blueair: final thoughts

Overall, both Levoit and Blueair air purifiers are fantastic choices for a home. Both brands boast quality HEPA and carbon filters and smart capabilities, so it's pretty toe to toe as far as which products get our thumbs up.

If you're living in an especially small home, then the Levoit Core 300S' compact design invites itself as a perfect addition to a kitchen worktop, desk, or sideboard. Although we would objectively say it falls just a tad short of the power that the Blueair Blue Max 3250i offers, it's still a top-rated choice to consider.

That said, if you're looking to improve the indoor air quality of a space measuring less than 48m², we think the Blueair Blue Max 3250i is easily the best air purifier money can buy offering the best filtration at a relatively affordable price tag.

However, as with any home investment, the choice remains yours as to which lucky model gets to come home with you. Rest assured, whichever air purifier you decide to opt for will prove itself as a valuable addition to any household and will likely become a non-negotiable once you get a feel for its effects inside your home.

In the meantime, while you sit and mull over your decision, our air purifier deals page is chock-full of other great models and products we've had the joy of testing. And keep an eye in case the Levoit and Blueair air purifiers we've put head to head today find themselves at a discount on there, too.

Knowing which type of air purifier is best for you before purchasing one will ensure that the investment you make is one that you'll be pleased with for years down the line. After all, there are so many options out there.

Of course, among the roster of the best air purifiers currently on the market, there are a handful of features that differentiate them from one another that go beyond just size and noise levels. And one thing you need to know before buying an air purifier is that these features can affect its efficiency.

While air purifiers generally work to achieve the same result of improving indoor air quality, certain types of air purifiers are more effective in specific situations and for addressing specific issues. For example, certain air purifiers help with allergies better, whilst some air purifiers are geared to help deodorise damp, musty smells in the home. So, this is how to choose which air purifier is best for you.

1. Filter type

An air purifier wouldn’t be able to do what it does best without a filter. It’s this filter that captures the small airborne particles and prevents them from re-entering your home - but just as it’s important to replace this filter regularly, it’s also important to choose the right filter type. After all, there are many to choose from.

In fact, most air purifier manufacturers use a combination of filters within their models to ensure they’re as efficient and as effective as possible. Here’s a little lowdown of the most common air purifier filters out there:

• HEPA filters: HEPA purifiers are often noted as the gold standard in air purifiers, standing as the best option if you're looking to invest in an air purifier to help with hay fever. This is because 'HEPA purifiers have an incredibly effective filter made up of thousands of extremely fine fibres and can catch the tiniest of particles, with a 99.97% efficiency in trapping particles, allergens, and pollutants,' explains Joshua Warren, air treatment expert at AO.com.
• Activated carbon filters: Alternatively, if you're looking to invest in an air purifier to get rid of bad odours in your home, it could be worth considering a model with an active carbon filter. 'Active carbon filter purifiers use activated carbon to absorb gases and odours, including volatile organic compounds (VOCs) from household products and smoke,' explains Joshua. 'These are best for homes with smokers, pets, or those concerned about eliminating odours and harmful gases.'
• Ioniser air purifier: Although it’s not technically a filter type, ioniser air purifiers offer an alternative method for cleaning the air. These ‘release negatively charged ions into the room to attach to positively charged particles like dust, bacteria, and pollen, making them heavier and easier for the air purifier to capture,' explains Colin Swift, product manager at AEG. However, some ionic air purifiers can emit harmful byproducts, like ozone, that can pose a risk to those with respiratory issues.

2. CADR rating

If you’re wondering which type of air purifier is best for you, it’s also important to consider the numerical specifications - most importantly, the CADR rating. This should be supplied within the product write-up of most air purifiers, although Dyson famously doesn’t provide CADR ratings for their air purifiers, and tends to offer their own specifications instead.

Marc Duckworth at Russell Hobbs, explains, ‘The clean air delivery rate (CADR) is a handy measurement that recognises the speed an air purifier can clean a certain volume of air. The higher the CADR, the larger the room the purifier is suitable for, but a super high CADR in a small room is unnecessary.'

Because of this, it’s important to understand the size of your home and determine your requirements for an air purifier. After all, if you just want to pop an air purifier on while you’re cleaning to help with dust, a high CADR may not be necessary. But if you want to successfully pollen-proof your home, a higher CADR would suit you best.

Understanding the CADR rating can also help you know how many air purifiers you need, and what size you need. And another way to do this is to look at the number of air changes per hour. As a general rule of thumb, Chris Michael, managing director of Meaco, advises:

• 3x an hour for minor problems.
• 5x an hour for problems that affect your health.
• 7-8x an hour for issues that see you have regular medical support/hospital visits (in these cases, talk to your doctor as well).

3. Noise levels

Another way to choose the right air purifier for your home is to consider noise levels. This is especially true if you plan on using an air purifier at night to help you sleep, as running any appliance overnight can result in unwanted noises and distractions.

As Lars Dunberger, technology development manager at Blueair, explains, 'Noise from air purifiers generally comes from the fan or motor and the air pressure through the filter.' And while noise levels can differ according to the design of the machine, most products come with a noise rating to help you know what to expect. This is measured in dB (decibel level) and tends to range between 18-60dB.

However, as Lars states, 'It should be mentioned that the dB value alone does not provide enough information to determine how "noisy" an air purifier is. The characteristics of noise, tone and how the individual subjectively perceives the noise also weigh in.'

This was certainly something I’ve found whilst testing air purifiers, with some models with higher dB ratings sounding like easy-to-ignore gushing air in practice, and some appliances with lower dB ratings causing more irritation due to whirring or mechanical noises.

4. Extra features

Nowadays, air purifiers aren’t just air purifiers. They can also be air purifying fans (like the Russell Hobbs Air Purifying Fan that I use in my own home), they can be air purifying fans and heaters like many Dyson models, and they can come with all kinds of other special features.

It’s important to consider these features when deciding which type of air purifier is right for you, as while some features may enhance your experience, others may be a hindrance or be unwanted in the first place.

So, it’s best to weigh up whether you want WiFi connectivity, specific ‘Sleep’ modes that dim any lights and reduce noise, and whether you want an air purifier that can also be controlled through an app. All of these extra features should be included in the write-up of any model, so make sure you know what these are before buying.

It’s also worth understanding the ongoing costs associated with your potential air purifier, too, especially when it comes to replacing the filter.

5. Energy efficiency

You can find more details in our guide on the cost of running an air purifier, but to ensure you're not spending more than necessary on running costs, consider the two main factors: the air purifier's wattage and whether it comes equipped with an automatic mode.

The lower the wattage, the less energy the air purifier will use to run. However, the biggest factor in better energy efficiency is opting for a model with a built-in air quality sensor and an automatic mode. This means that the air purifier doesn't need to be left running on a high (energy-hungry) fan setting to do its thing.

FAQs

What is the best method of air purifier?

Generally speaking, many experts would agree that HEPA filtration is the most effective and safest method for purifying and improving indoor air quality. However, the choice still lies with you on which air purifier you deem best for your specific needs and situation.

What are the disadvantages of air purifier?

Although there are many advantages of an air purifier, there are also some disadvantages to consider. These include:

• Filter replacement costs.
• Some air purifiers are quite large.
• They can be noisy.
• They can be hard to incorporate into your design aesthetic.
• The sheer number of models out there.
• It’s another appliance using energy in your home.
• Some models generate harmful ozone.

Having read the above advice, we hope you feel better placed to decide which type of air purifier is best for you, so you can confidently make the investment with no regrets.

Before I became Ideal Home’s expert in all things air quality, I got caught up in the air purifier wave. They were the talk of the town, everyone was buying them, and I just didn’t want to be left out. In doing so, I made some serious buying mistakes - and there were so many things I wish I knew before buying an air purifier.

While I’m now a huge fan of the best air purifiers, I know from personal experience that doing little-to-no research and buying the wrong one (well, buying the wrong three, in my case) is a serious waste of time, money, and effort. But as it’s now my job to test air purifiers and understand everything there is to know about them, I’ve realised that I’m probably not the only one who has made these poor choices.

That’s why I thought I’d share with you the 6 things I wish I knew before buying an air purifier so you don’t make the same mistakes as I did. Hopefully, this should lead you to the perfect purchase with minimal effort on your part. And yep, you can thank me later.

1. Understanding what you want from it is key

Appliance trends come and go, and even if they stick around they’re constantly changing and evolving. And while it can be easy to buy an air purifier purely because everyone else seems to be, I know from experience that understanding what you want and knowing which type of air purifier is best for you is key.

That’s because there are so many different types of air purifiers out there, from air purifiers to help with hay fever to air purifiers that help with mould because of the different filter offerings available.

'For instance, if you suffer from allergies, a purifier with a HEPA filter is ideal. If you are primarily concerned about odours, look for a model with an activated carbon filter,' advises Joshua Warren, AO.com's air treatment expert.

And as someone who suffers from hay fever and shares a home with a dog (and therefore a lot of pet dander and hair), I can vouch for the fact that buying the wrong air purifier was a complete waste of money. In fact, I used one for about a month before swapping it out for a different model.

2. Sometimes the extra bells and whistles are worth it

In today’s day and age, air purifiers are so much more than just air purifiers. They can also be air-purifier fan combos like the Dyson Purifier Cool PC1, and they can even be air purifiers that are also fans and heaters like the Dyson Purifier Hot+Cool Formaldehyde HP09 Purifying Fan Heater. Basically, there’s no end to the bells and whistles that can come with them.

I recently tested the Shark NeverChange5 Air Purifier and gave it a glowing 4.5-star review. In fact, it’s still the air purifier I use in my home to this day - and that’s largely due to the extra perks that come with it. For starters, it comes with odour cartridges that release a delicious scent when it’s purifying your home (although you can turn this off if you want to).

And secondly, you don’t need to replace the filter for a whopping five years, which is way less than how often you need to replace other air purifier filters. This will ultimately save me money and a whole lot of hassle in the long run. But that’s just the start of what these modern air purifiers can offer.

From smartphone apps to remote controls and even Alexa compatibility, these extra functionalities can drastically improve the overall ease of use and enjoyment of an air purifier. So, I’d always suggest opting for them - as long as you know you’re going to make the most of them.

3. You need to buy the right size

Air purifiers come in all shapes and sizes, spanning from itty bitty models that are perfect for improving air quality in a small bedroom to larger models for bigger family households. However, this size isn’t directly related to the dimensions. Instead, it’s related to the recommended room sizes - as some are more powerful than others.

This will outright determine how many air purifiers you need, as you could opt for one larger air purifier that will suit larger spaces or buy multiple smaller air purifiers that will target smaller rooms. This is echoed by David Miloshev, appliance technician at Fantastic Services.

He says, 'For example, if you need it for a small room, it'll be unnecessary to purchase a large device because it'll consume too much electricity (ultimately running up the cost of running an air purifier). On the other hand, a small air purifier won't clean the air effectively if you put it in a large room of about 55 or 90 square meters. For such space, you’ll need a large device.'

Because of this, it’s important to assess the specs of any air purifier you want to buy. And if you don’t know the size of the room or space you want to use this appliance in, you’ll need to get the measuring tape out.

4. Some are louder than others

Although I personally like a bit of white noise when I’m trying to sleep and therefore don’t mind the gentle hum of an air purifier, I appreciate that everyone is different. My own husband, in fact, hates that the appliances I test often disrupt his sleep. That’s why one of the things I wish I knew before buying an air purifier is the fact that some are louder than others.

If noise is an issue for you, the best way to ensure you’re making the right purchase is to take a deep dive into the specifications and check out the decibel (dB) rating - and the higher that rating, the louder it is.

Lars Dunberger, technology development manager at Blueair, also adds, ‘'For any devices designed to be used in the bedroom, it's also worth looking for the Quiet Mark certification, which is only awarded to the quietest devices on the market.'

Some also have a dedicated ‘Sleep’ mode - like the Levoit Core 300S - which means that it’ll not only reduce the noise levels but often turn off any lights on the unit itself. This should help you out if you want to use an air purifier to help you sleep.

5. Some air purifiers can be harmful

If you were to ask me whether air purifiers are worth it, I’d undoubtedly say yes. But I’d also say that only some air purifiers are worth it, as speaking from personal experience, ozone production is something I didn't even know I had to consider when buying an air purifier. I was under the impression that all air purifiers simply purified air (genius, I know).

So, when I switched on my air purifier for the first time and was met with a smell akin to harsh cleaning products, I was utterly confused. Turns out it was ozone. Needless to say, I quickly returned it, but if you're wondering why your air purifier smells, this could be a reason.

But what is ozone? Well, it’s a gas often used to help emit odours from the home. And as David says, 'Even though air purifiers are devices meant to purify air, some of them can still be harmful because they can emit ozone, which harms your lungs. To avoid this, look into the specifications and choose a product that has been tested and proven not to produce ozone.’

Thankfully, many air purifier brands are now straying away from using ozone, but this is still something to look out for - and it’s something I definitely wish I knew before buying an air purifier.

6. It’s all about the CADR

When I bought my first air purifier, I bought it based on aesthetics alone. I just assumed that all air purifiers were created equally, and that I had the freedom to choose an appliance that suited my home decor and the style of my home. However, I quickly realised that that wasn’t the case, as where air purifiers are concerned, it’s all about the CADR.

The clean air delivery rate (CADR) is one of the most important aspects to look at before buying an air purifier, yet is often the most overlooked. This is essentially the number that will determine how effective the device is.

In short: the higher the CADR, the faster the machine cleans the air. If you're buying an air purifier to help with allergies or you want to have an air purifier on while you’re cleaning, you should be prioritising models with a higher CADR and taking note of the recommended room size.

'The figure is based on independent tests performed by the Association of Home Appliance Manufacturers (AHAM), which in turn recommends a suitable room size for an air purifier based on its CADR score,' explains Lars.

FAQs

What features are most important to consider when buying an air purifier?

When buying an air purifier, the most important thing to understand is your specific needs for purchasing one. Make sure you opt for models with certain filters to best assist your needs, consider the size of the model in relation to where you plan to place it, and its noise levels.

As a general rule of thumb, keeping these immediate three factors in mind will help you make an informed decision before buying an air purifier.

What to avoid in air purifiers?

Where possible, it's best to avoid air purifiers that generate ozone. For domestic use, it's recommended to opt for models that don't produce ozone because this can be very harmful to human lungs when inhaled – which is the opposite effect we're attempting to achieve from investing in an air purifier in the first place.

There you have it, those are the top things I wish I'd known before buying an air purifier. Let me know if these are helpful in the comments!

Our Blueair Blue Pure 511 air purifier review puts the brand's most affordable, entry-level air purifier through its paces to see if it offers good value for money compared to the best air purifiers the Ideal Home team has tested.

The Blueair Blue Pure 511 air purifier is the brand's first sub £100 air purifier, designed to make air purification more affordable. According to Lars Dunberger, Technology Development Manager at Blueair, this lower price point has been achieved by 'stripping back smart technology and interactive features to simply deliver a high performing air purifier that looks good'.

That means that the Blue Pure 511 lacks any bells and whistles, but offers an impressive Clean Air Delivery Rate for its size and price point, with a CADR of 191m³/h that makes it suitable for filtering the air in a space up to 38m². 

I tested it out in my own home to see how it performed in practice. Read on to see how I got on.

How I tested

Assembly and set up

The good news is that there's no assembly needed with this air purifier. Simply unbox, unwrap, and you're ready to plug it in and switch it on!

Design

The Blue Pure 511 echoes the design of Blueair's more expensive air purifiers, with a cylindrical design and the lower section of the air purifier covered in a woven fabric which doubles as the pre-filter.

The Pure 511 air purifier is similar in looks to the higher specification Blueair Blue Max 3250i, which we rate as the best air purifier overall based on its combination of style, performance and value for money.

However, when compared side by side, (the Blueair Blue Max 3250i is on the left and the Blue Pure 511 on the right in the image below) it's obvious up close which is the more expensive model, mainly due to the fabric used on the Pure 511.

Unlike the higher specification Blueair Blue Max 3250i, which features a snug-fitting elasticated fabric cover, the cover of the Blue Pure 511 instead has just has one elasticated section which is covered by a fabric flap that fastens with velcro. This means the fit of the Blue Pure 511's fabric pre-filter is baggier and overall it feels to lack the same finish quality as the Blue Max 3250i.

Compared with the Blue Max 3250i, the Blue Pure 511 also lacks an air quality indicator light, and that's because there's no built-in air quality sensor on the Blue Pure 511. This means that there's no automatic mode on the Blue Pure 511, just on/off functionality and the choice of three fan speeds all controlled by two fairly small buttons on the top of the unit.

Performance

Considering its relatively affordable price point, the Blueair Blue Pure 511 air purifier offers a decent CADR (Clean Air Delivery Rate) of 191m³/h which makes it suitable for filtering the air in a space measuring up to 38m².

As mentioned, the Pure 511 features three fan speeds that you can adjust manually via the controls at the top of the air purifier, but what it lacks in comparison to more expensive air purifiers is an automatic mode. 

Having now put a whole host of air purifiers through Ideal Home's air purifier testing process, I think this lack of functionality is a big loss. However, it's the lack of built in air quality sensor that makes the Pure 511 more affordable. 

What that means in practice is that you'll need to operate the Blueair Blue Pure 511 air purifier manually. An air purifier with an automatic mode uses that built-in air quality sensor to measure the air quality, and then uses the air quality data to control the air purification process itself. For example, if the air quality suddenly dips, then the air purifier will sense this and turn itself on to filter the air and return your room's climate to best possible air quality as quickly as possible.

Because the Blueair Blue Pure 511 air purifier doesn't have this feature, it's up to the user to decide when to turn the air purifier on and off. This can prove tricky, as in practice that either means relying on your nose or your allergies to alert you to a dip in air quality – not always the most reliable method as many airborne pollutants don't have odours. Alternatively, you could leave the air purifier running constantly, but – even though the Pure 511 isn't particularly energy hungry – this could still rack up your running costs.

However, one thing that most of us can easily identify is the fumes from frying bacon! So this was the first test I put the Blueair Blue Pure 511 air purifier through to test its filtration powers.

All of the air purifiers with automatic modes that I've put through the fried bacon test switched up to their highest fan speeds once they'd detected bacon frying fumes, so I gave the Blueair Blue Pure 511 air purifier a headstart and began running it on its highest fan speed as soon as the plant-based bacon hit the pan.

After about four minutes the bacon had crisped up, so I left the Blue Pure 511 running in the kitchen with the door closed whilst I exited and tucked into my bacon butty. In previous tests, air purifiers with a built-in air quality sensor showed that the kitchen had been cleared of frying fumes in about 10-15 minutes, so I left the Pure 511 running for a quarter of an hour, and then re-entered the kitchen to see if I could still smell cooking fumes. 

There was a noticeable reduction in the bacon fumes, however, there was still a lingering smell in the kitchen – more so than with the more powerful air purifiers I've tested.

I used an independent device fitted with an air quality sensor to see how the Blueair Blue Pure 511 had performed, and the air quality reading came back as 'good' rather than 'very good' initially. I left the Pure 511 running for longer, and after around 20-25 minutes in total the air quality reading changed to 'very good'.

I also put the Blue Pure 511 air purifier through Ideal Home's smoke and VOC tests, by allowing a match to burn out next to the air purifier and spraying deodrant nearby to see how well it removed both odours.

In all of our tests the Pure 511 did a decent job, however, it wasn't the fastest at filtering out airborne contaminants – unsurprisingly considering its smaller size and more affordable price tag. And I definitely missed having that built in air quality sensor that allows automatic performance and access to in depth air quality data.

Ease of use

The plus side of the Blue Pure 511's limited functionality, is that it does make its controls fairly easy to master. 

There's just an on/off button on the top of the unit, and then a second button that controls the three fan speeds. Press once for the lowest fan speed, twice for medium fan power, and three times for the highest fan speed.

A little confusingly, in the instruction manual Blueair refers to these three fan speed settings as Night, Everyday, and Boost mode, but all they really seem to do is change the fan speed, and on the air purifier itself they're simply labelled 1, 2, and 3. 

That said, you have to peer very closely at the top of the unit to make out those numbers. The font choice seems uneccessarily small, and would be tricky for anyone with any kind of visual impairment to read. There is also a (very) small light that momentarily shows up next to each speed setting so you know which one you've selected, but annoyingly this light disappears almost instantly, so when the air purifier is running you can only judge by its volume which speed setting it's on.

The buttons themselves are also quite small. They're formed by indentations in the hard plastic control panel surface, and I found it could be a bit hit and miss as to whether each press registered. 

All in all, what should be a very easy to use air purifier is made harder than needs be because of those too small and not very responsive control buttons, which is a shame.

Noise levels

The Blueair Blue Pure 511 air purifier's official noise rating is between 24-49dB, dependent on which fan speed you have it running on. 

This is noisier than the slightly more expensive Blueair Blueair Blue Max 3250i air purifier, but on a par with most mid-range air purifiers of this size.

In practice I found the noise levels easy enough to ignore, and its certainly quieter than most larger and more powerful air purifiers.

Portability

The Blue Pure 511 is one of the smallest air purifiers I've tested, measuring just H34 x W20 x D20cm. 

That makes it a great option for small spaces, and, weighing in at just 1.9kg, it's also lightweight enough to pick up and move around the home. However, it does lack any hand holds, so you do need to have the ability to grip its cylindrical build with two hands. 

A built in carry handle would have been a nice touch, although no doubt this would have added to the budget air purifier's price tag and pushed it over the £100 mark.

Its small footprint also means it's a good option for placing on a shelf or work surface, or tucking onto a bedside table.

Energy use

In comparison to most air purifiers, the Blueair Blue Pure 511 offers pretty low energy usage, running on just 2-16W of electricity depending on which fan speed you have it operating in. 

However, because it doesn't have a built-in air quality sensor, that means there is no automatic mode to automatically regulate the air purifier's fan speed when air quality dips or improves. That means the Blue Pure 511 relies on the user to determine when the fan speed should be switched up and down through the three speed settings, and when the air purifier should be turned on and off. If you leave it running continuously, that could mean your energy costs rack up more than they would with an air purifier with automatic functionality.

You can find out more details about how much it costs to run an air purifier in our dedicated guide.

Filter replacement

The Blueair Blue Pure 511 air purifier is a relatively affordable buy, however, as with all air purifiers, you also need to factor in the ongoing cost of buying replacement air filters.

Manufacturers usually advise that an air filter should be replaced roughly every six months, as after this point the filter will gradually become clogged up with particulate and its efficiency reduced. And the Pure 511 is no exception. The air purifier has an indicator light that glows red when the air filter needs replacing, and Blueair advises this typically occurs after around six months of operation.

Thankfully, when its time to replace your Pure 511's filter, you'll find they're cheaper than most. As of writing, replacement filters for the Pure 511 cost around £25, which is at the lower end of the price scale. For comparison replacement filters for the (admittedly much larger and far more powerful) AEG AX91-604GY Connected air purifier cost around £100!

Verdict

Overall, the Blueair Blue Pure 511 air purifier feels more basic – both in terms of style and functionality – than our top-rated Blueair air purifier, the Blue Max 3250i. Especially considering the Blue Max 3250i isn't that much more expensive.

The Blueair Blue Pure 511 is also less powerful than the higher specced Blue Max 3250i. The Pure 511 offers a 191m³/h CADR that can improve air quality in a space up to 38m², whilst the Blue Max 3250i has a 239m³/h CADR and can manage air quality in a space of up to 48m2. 

But, the Blueair Blue Pure 511's CADR is still impressive for an air purifier at this price point. In comparison, the most affordable air purifier Ideal Home has tested, the Beko ATP5100I Air Purifier, can only manage the air quality in a much smaller 13m² space.

For some, the Blue Pure 511's lack of Wi-Fi connectivity will be a bugbear as this means no remote or voice-activated controls. However, in my opinion, the Blue Pure 511's biggest downside is its lack of built-in air quality sensor which means no automatic mode. You can toggle the Pure 511 through three fan speeds for low, medium, or high filtration, but without Automatic mode, that still makes for very limited functionality. And unlike models with built-in air quality sensors, that means there's no air quality data available with the Pure 511. 

If you're looking for a compact air purifier that will make short work of improving the air quality in a small to medium-sized space, then, personally, I would opt for the brilliant Blue Max 3250i with its air quality sensor and automatic mode instead. 

However, if price is paramount, the more affordable entry-level Blue Pure 511 air purifier still does a decent job in a small space. In my opionion, it just lacks the extra functionality and design flair to make it truly user-friendly.

Almost every member of the Ideal Home team has an air purifier, but as someone who struggles with hay fever, lives in a built-up town, and has a dog that sheds, I've taken a particular interest in these handy appliances. But I bet you're wondering how we test air purifiers at Ideal Home? Well, wonder no more.

As the team's resident air quality expert, it's my job to keep our best air purifier guide up to date with the top-rated models on the market. But compiling this guide is so much more than just personal opinion. Behind the scenes, we've created a foolproof (and thorough) testing process to ensure every air purifier is suitable for the everyday home.

From the setup process to the bacon test (yes, there's a bacon test!), myself and a team of approved testers put every air purifier - from budget air purifiers to air purifier-fan combos - through these tests. Then, only those that score highly will make it into the guide, and below I've outlined exactly how we test air purifiers so you can see how it's done.

Our testing philosophy

At Ideal Home, we take how we test products extremely seriously. And while those who already own an air purifier will probably agree that it’s a non-negotiable appliance, those who are new to them need not only be won over, but also feel confident that they’re choosing the right model for their needs.

Because of this, we have built our air purifier testing process around the premise that this appliance must include features that genuinely improve your home and life. So, we test air purifiers for at least two weeks at a time, confirming their specifications and measuring their effectiveness in improving air quality.

During our review process, each model is benchmarked against certain criteria. This includes:

• Unboxing and setting up: Is it packaged in eco-friendly materials, and how long does it take before your air purifier can start cleaning your home’s air?
• Design: How large is the air purifier, and how well will it fit into the majority of homes?
• Performance: How well, and how quickly, does the air purifier respond to changes in air quality? How does it battle smoke, VOCs, dust and odours?
• Cleaning and maintenance: How often does the filter need to be replaced, and what are the associated costs?
• Comparisons: How does each model compare to others with similar features and specifications? Is one cheaper than the other?

Unboxing and setting up

Before I get to the nitty gritty of any air purifier review I write, my first section will always focus on the unboxing and setting up of the appliance. This is something the Ideal Home team does with any product we test, as we're huge advocates for green living and eco-friendly packaging.

And while many brands now send their products in minimal, recyclable packaging, there are others who ship their products off in unnecessary (and unrecyclable) alternatives. I will always note when this happens so you can be aware, too.

During this stage, I also like to take note of how heavy the box is, whether one person can easily carry it themselves, and what's actually inside the box - especially if the contents include spare accessories like filters or scented cartridges.

Although I test appliances for a living, I don't appreciate having to spend hours setting them up. That's why I always assess how easy the air purifier is to set up when we test air purifiers at Ideal Home, too.

Best case scenario? I'd just need to unwrap the filter, pop it in place, and plug the appliance in to start using it. However, more modern air purifiers that come with Wi-Fi connectivity, apps, and extra parts often need some extra legwork, which I think everyone should know before they buy - especially if they're not as tech savvy as others.

Then, I take the time to assess the controls and features of the air purifier, understanding and relaying how easy they are to use and what you can expect from it. For example, you may want to use an air purifier to help hay fever, in which case a HEPA filter and a Sleep Mode would probably suit you best.

The design

While I tend not to judge a book by its cover, part of how we test air purifiers at Ideal Home is judging an air purifier by its design. After all, when adding a new appliance to my home, I want to know both how well it will perform and how well it will aesthetically fit into my space. Because of this, I always give myself time to assess the design of each air purifier I test.

Of course, whether an air purifier looks good or not is entirely subjective, but I always take note of how big (or small) the appliance is, what the colourway is like (and whether there are any alternatives), and how versatile I think the design is.

This is particularly important now, as the aesthetic of air purifiers has changed dramatically over the past few years and the standard, boring white appliances are now being replaced with multi-purpose, stylish alternatives that can fit seamlessly into your home without looking like an eyesore.

My particular favourite so far is the Dupray Bloom, which doubles up as a plant pot and a table, too.

Our air purifier tests

To help my readers determine which air purifier is right for them, I like to perform a series of air purifier tests. And whilst most air purifiers' technical specifications – such as CADR (clean air delivery rate) and HEPA filtration performance – are based on the air purifier's performance in a sealed laboratory, I prefer to test out each air purifier within a home environment. This means I can assess each air purifier's performance in real-life conditions.

Our first test involves testing each air purifier's ability to detect and filter out smoke. If the air purifier features a built-in air quality sensor, I switch it into automatic mode, light a match a safe distance from it, allow the match to burn out, and then time how long the air purifier takes to register the drop in air quality.

I then time how long it takes each air purifier to filter the smoke particles from the air and return the air quality to a 'very good' level of below 10µg/m³ PM2.5. I also do a 'nose test' to see if someone entering the room after the air purifier has 'done its thing' can still smell any trace of smoke.

If the air purifier doesn't feature an automatic mode, then I only perform the latter part of the test, and we use an independent device to measure how long the air purifier needs to run before the air quality is improved.

I also perform a similar test by spraying aerosol deodorant into the air near the air purifier, and timing how long each air purifier takes to register and then filter out any VOCs (Volatility Organic Compounds) and odours that may be present.

This test is particularly important to me, as I know that VOCs are everywhere, despite many people not realising it. In fact, they're released from new furniture, mattresses, paints, aerosol sprays, and more. They can be extremely harmful if left in the air, so I always like to test how long an air purifier takes to react and remove them from a home to keep everyone safe.

Next, I also put each air purifier's odour-filtering capabilities to the test in the kitchen. Our standard test involves closing the kitchen windows and doors, leaving any extractor fans switched off, and frying up two rashers of bacon (veggie bacon for me, or normal bacon for our other testers) until it's nice and crispy.

I then time how long each air purifier takes to register the decrease in air quality caused by the bacon fumes, and how long each air purifier takes to remove the cooking fumes from the kitchen.

This is the test that usually sends each air purifier into overdrive, with most of those appliances that feature a built-in air quality sensor registering a deterioration to 'very poor' air quality as soon as the bacon starts frying.

The testing isn't over at this point, though. As Ideal Home's Vacuum Expert, I'm also extremely conscious of the fact that vacuuming spreads dust - ruining my home's air quality in the process.

With this in mind, I also put each air purifier through a dust test. This (very glamourously) involves emptying the contents of a vacuum cleaner next to the air purifier to see if it triggers a response from those air purifiers that feature a built-in air quality sensor.

Myself and my Ideal Home-approved testers then time how long it takes the air purifier to react to the mess and how long it takes the air quality to return back to normal afterwards.

During this stage, I also like to assess the noise levels of the air purifiers before comparing all of the results of these tests to rate each air purifier's overall performance.

Cleaning and maintenance

It's super important to clean the things that clean for you, which is why knowing how to clean an air purifier is must-have knowledge. However, this varies from model to model.

That's why, as part of the air purifier testing process, I also carve out a section to assess all of the cleaning and maintenance requirements of each model.

It may be that the air purifier can last five years without needing anything other than a quick vacuum of the filters, or it may be that the filters need to be washed (or even replaced) every six months.

I think it's important to share this information with potential buyers, as the cleaning and maintenance of an air purifier can incur costs and a lot of your time. So, I want you to know what you're getting into before you come back and hunt me down for not providing every little nugget of information.

Comparisons

I believe it's incredibly important to pit the air purifiers myself and the rest of the team test against each other, especially as I want to constantly update our buying guide with the most up-to-date and accurate information.

And as new air purifiers are released quicker than you can say 'airborne particulates,' it's down to us to keep you in the loop on whether these new products are worthy of their place in the guide.

That's why I always compare new air purifiers with older models in my reviews, to ensure you know that you're getting the best option for you and your needs. This also helps us maintain a flawless testing process across the board. So, it's a win-win.

Coming to a verdict

If you've got this far, thanks for sticking with me. After all, the verdict is ultimately what everyone wants to know, right? And to come to a verdict on the best air purifiers, I take all of the information above - including the overall cost and the value for money, and how much an air purifier costs to run - to give it an overall star rating out of 5. Those that score 4 and above will be given one of our Ideal Home Approved badges.

All positives and negatives of each model will be clearly outlined, and myself and the team are always 100% honest and impartial when it comes to this rating. We're also in no way impacted by the fact that these air purifiers are often supplied by the brand for us to review. In some cases, we won't publish a review if we don't think the product deserves one.

If you're currently dealing with a scratchy throat, itchy eyes, and a sniffly nose, there's a high chance that you're frantically Googling: 'Does an air purifier help hay fever?' and 'Does an air purifier help allergies?' After all, these appliances have become the talk of the town in recent years.

The good news is that the best air purifiers are a worthy addition to any household as they can remove airborne pollutants, impurities, and even odours. But those who struggle with seasonal (and year-round) allergies probably want more insights on whether this appliance can actually make a difference to hay fever and allergy symptoms.

That's why I've reached out to air quality experts to see whether this popular appliance is a surefire way to allergy-proof your home. The answer? An air purifier can help with hay fever and allergies, but only under certain conditions.

Does an air purifier help hay fever and allergies?

The short answer? Yes, an air purifier does help with hay fever, and an air purifier can help with allergies! However, the long answer is that air purifiers can only help with hay fever when you choose the right kind.

While air purifiers can get rid of dust for those with allergies to dust (which is surprisingly more common than you'd think), reduce pet dander for those with animal allergies and remove airborne pollutants from your home, it’s important to realise that no air purifier is 100% effective at removing these contaminants from the air. It also won't cure your allergies; but it may reduce your symptoms and make your home more allergy-friendly.

This is especially true when thinking about hay-fever-inducing pollen, as these pollen particles are minute. In fact, they’re generally about 15-100 microns in size.

This means that they can easily fit through the cracks in your windows and hitch a ride on your pets, ultimately making their way into your home in the process. And most air purifiers only have the ability to remove 99.97% of airborne pollutants from the air - with most models filtering down these pollutants to 0.3 microns in size.

Some higher-end, higher-quality models, like the Blueair Blue Max 3250i Air Purifier, can filter down to 0.1 microns, but this is very rare. Because of this, an air purifier will only help with allergies if you choose the right one. If you don’t, you may find that it doesn’t make a difference at all.

This is echoed by Chris Michael, Managing Director of Meaco. He says, ‘Pollen is a fine powdery substance. Not all air purifiers are built to effectively capture and trap such small particles. To be sure of removing most of the particles from the air, you need to choose a unit that has a HEPA filter.’

What to look for in an air purifier for allergies and hay fever

1. The CADR

If you want to buy an air purifier to help with allergies, you need to look at the specs. After all, air purifiers are all so different. Most importantly, you should look at the recommended room size and the CADR rate (Clean Air Delivery Rate). This should also help you decide how many air purifiers you need in your home.

Lars Dunberger, head of technology at Blueair, explains, ‘The CADR shows how many cubic meters the air purifier will clean every hour. The higher the CADR value, the more air it cleans in an hour.’ And if you’re using an air purifier for a specific allergy - i.e., for pet dander or to combat rising pollen levels - opting for a higher CADR value will suit you best.

2. The ACH

Alongside the CADR number, you should also keep an eye out for the ACH value. This stands for Air Changes per Hour, which measures how many times the air purifier replaces the total volume of air in the room with fresh, filtered air over a 60-minute period. Again, the higher the better.

Johnny Liang, Air Purifier Specialist at Levoit, advises, ‘For households with pollen allergies, pets, or exposure to poor outdoor air quality, increasing ACH to around 4.8–5 times per hour is recommended for more thorough air cleaning.’

3. The filter type

I've already mentioned HEPA filters, which are High-Efficiency Particulate Air filters and are used to catch these minute particles. In most cases, they can catch upwards of 99.97% of pollutants from the air. Because of this, it’s important to choose an air purifier with a HEPA filter if you want to help with hay fever.

Chris adds, ‘These filters are extremely fine, so can trap smaller particles than general air purifiers. If the HEPA filter has captured the pollen then the person with the allergy cannot be breathing it in! Choosing the right size HEPA air purifier for the room space alongside any treatment or medication you have for the allergy problems in your household, should help remedy symptoms.’

To ensure an air purifier is continuously helping your allergies, it’s also important to replace an air purifier filter regularly to keep it working as effectively and as efficiently as possible.

4. The physical size

Placement is everything when it comes to the effectiveness of an air purifier. This is echoed by Lars, who states, ‘Placing an air purifier in rooms where you spend the most time, like the bedroom or living room, can drastically improve your air quality during this critical time of year.’

Because of this, it's important to think about the physical size of this appliance before you use an air purifier to help with hay fever or other allergies. You need to make sure that you have the space to keep it in those important rooms.

In some instances, it may make more sense to buy multiple air purifiers so multiple rooms are covered at the same time.

The best air purifiers for hay fever and allergies

FAQs

If you suffer from hay fever or other allergies, an air purifier will soon become your best friend.

Air purifiers are proven to remove airborne pollutants and even remove odours from your home, which is why you might be wondering: Why does my air purifier smell? And what can I do about it?

The best air purifiers are certainly worthwhile investments. This small home appliance can improve air quality and help you breathe easily in a world full of contaminants and potentially dangerous airborne particulates. And while air purifiers can also tackle the spread of mould and eliminate smells from your home, they’re not bulletproof.

Every so often, an air purifier starts to smell. The appliance continues to draw in the dirty air, but it seems to release a lingering, undeterminable smell back out - and that’s not what any homeowner wants. So, here are a few reasons why your air purifier smells. 

Why does my air purifier smell? 

Nobody wants a smelly air purifier, but very few people know what it means when this pungent smell starts to emanate from their appliance. That’s exactly why we’ve consulted with the experts, and below, you’ll find 5 potential reasons why your air purifier has started to smell and what you can do to make that smell go away.

1. You need to change the filter

An air purifier wouldn’t be an air purifier without a filter. It’s this filter that captures all of the airborne pollutants in your home, and it’s only natural that this will get clogged up over time. 

It’s noted that most air purifier filters only last between 6 and 12 months (this varies due to usage and the air quality in your home), and Chris Michael, Managing Director of Meaco, explains, ‘If the air purifier is starting to smell it’s a sign that the filter needs changing.’

And when you think about it, this makes sense - especially with air options like the Dyson Hot+Cool Formaldehyde air purifier, which also filters out formaldehyde from the air. As formaldehyde is a colourless chemical with a strong, pickle-like odour, it’s not uncommon for air purifiers to absorb and maintain this scent. 

Of course, we’d love to tell you that you can simply clean a filter, but that is rarely the case. Most of the filters in air purifiers on the market today need to be fully replaced rather than cleaned to ensure an efficient appliance. 

However, as soon as you replace the filter, it should stop your air purifier from smelling. 

2. The pre-filter needs cleaning

Most air purifiers come with two or three different filters, one of which is the pre-filter. This allows the air purifier to filter as much as it can from the air, making it perfect for those who want to use an air purifier to stop dust. 

Specifically, a pre-filter usually sits in front of the main filter. It provides the first stage of filtration and typically captures the larger pieces of dust, debris, and airborne particles in your home. It can even catch hair, but this may result in a horrible smell. 

Cristina Raboj, Global Proposition Manager at Philips, explains, ‘When your air purifier's pre-filter or filter surface is dirty, or not cleaned regularly, it may cause a dusty odour or bad smell. You need to clean the pre-filter or filter surface once a month or when indicated by the appliance.’

If you’re not sure where your pre-filter is, you should always refer to the manual or contact the manufacturer. 

3. The filter is damp

While you may already be taking steps to get rid of damp in your home, it’s important to realise that damp can also affect your air purifier. Just as your clothes smell musty when dried inside, your air purifier filter can also smell musty when kept inside a damp home. 

‘If the indoor humidity level is high, your filter could get damp and emit a strange smell,’ explains Cristina. ‘You can put the filter in a well-ventilated place for a couple of hours to reduce the smell.’

If you can, it’s also a good idea to keep your air purifier away from moisture-rich rooms, such as the kitchen or the bathroom. If you can’t do that, or you’re looking to banish condensation from your home, investing in one of the best dehumidifiers wouldn’t go amiss.

4. It’s brand new

If you’ve bought this appliance because an air purifier can help with allergies, you might worry that something's wrong when you notice the strange smell coming from it. After all, it’s never a good sign when a brand-new appliance smells a little funky. 

But it’s important to give your air purifier time to settle before heading back for a refund. Similar to how the best mattresses have to go through an off-gassing period, the best air purifiers also need to take a moment to breathe. In fact, it’s very normal to catch a whiff of plastic. 

Cristina says, ‘The first few times you use your Philips Air Purifier, it may produce a plastic smell due to the plastic materials of the appliance. Do not worry, this is normal and will fully disappear within a few days.’

Lars Dunberger, Blueair’s Technology Development Manager, echoes this, saying, ‘Sometimes, new air purifiers may emit a temporary odour due to the materials used in manufacturing. This is known as off-gassing and should dissipate over time.’

Just be wary that this smell shouldn’t stick around much longer than a few days. If the smell persists (or turns into a burning smell), you should definitely seek advice from the manufacturer. 

5. It’s faulty

If you’ve explored all of the above and still have a smelly air purifier, it may be that your air purifier is faulty. And if you get a whiff of burning or smoke, you should unplug your air fryer and stop using it immediately. 

Like all electrical appliances, air purifiers can become faulty over time. It’s uncommon, but it can still happen - which is why it’s always a good idea to buy an air purifier from a reputable retailer that can offer refunds, exchanges, and warranties. 

If it's really old, it may be time to upgrade to a newer model. 

FAQs

How do you get the smell out of an air filter?

The most common reason an air filter starts to smell is because it needs to be replaced or cleaned. Most air purifier filters only have a lifespan of around 6 months to a year, as they often become covered in dust, pollutants, and contaminant particles. 

However, that’s not the only reason an air filter may smell. It may be that the filter is damp, faulty, or brand new and needs time to breathe before the smell goes away.

But if you ever notice a burning smell, you should turn it off immediately and seek advice from the manufacturer.

What can I put in my air purifier to make it smell good?

If your air purifier smells bad, this is something you need to address. In fact, you may have to replace or clean the filter. 

Most experts would advise against putting things like essential oils into an air purifier, as this could mess with the efficiency of the appliance and affect the efficiency of the filter itself. 

So, check to make sure that the filter is clean, the appliance isn’t faulty, and that the filter isn’t too damp.

Does your air purifier smell? Hopefully it won’t anymore after reading this. 

As one of Ideal Home's product experts, I've now tested multiple air purifiers, and the Philips 3000i Series AC3033/30 Connected is one of my top recommendations whenever friends ask me which is the best air purifier to buy.

The downside is that this premium air purifier usually comes with a premium price tag. At its full recommended retail price, the Philips 3000i Series will set you back around £450. Ouch. That's probably much more than most of us can afford to invest in an air purifier, however impressive its performance may be. 

The good news is that right now the 3000i Series is on sale at both Amazon and John Lewis with nearly £200 off. And whilst its sale price still isn't cheap, I do think it's a great investment if you're in the market for an air purifier that can make short work of managing airborne pollution and allergens in your home. Especially if you're dreading the return of hay fever season as pollen levels rise.

Philips has a wide selection of air purifiers in its range, but the 3000i Series is the brand's most powerful. This air purifier can filter particulate from the air in a space up to 135m² – which is a huge area compared to most air purifiers on the market – and has a CADR of 520m³/h. CADR stands for Clean Air Delivery Rate and means the 3000i Series can filter a lot of air quickly and efficiently.

When I put it to the test for Ideal Home's Philips 3000i Series AC3033/30 Connected Air Purifier review, I was really impressed by how quickly this air purifier filtered out VOCs from aerosols, smoke, and cooking fumes in my home. 

Thanks to its HEPA filter with activated carbon, the 3000i series can also capture pollen, pet dander, and household dust, as well as dust mite allergens, making it a useful investment for anyone who suffers from airborne allergies.

However, what impressed me most during testing was the level of air quality data the Philips 3000i Series provides. 

Unlike most air purifiers at this price point, rather than just a general indication of your home's air quality levels, the 3000i Series uses its built-in air quality sensors to give you real-time readings of your home's Indoor Allergen Index, PM2.5 levels and gas levels (which measures VOC and odours).

Whilst you don't need to know this data for an air purifier to do its job, if you suffer from allergies or live in a traffic-congested area and are concerned about outdoor pollution entering your home, this is all useful data to help you know when to turn the air purifier on, or when to open a window and allow fresh air to circulate instead.

In my experience, this level of air quality data is only matched by the Dyson Purifier Hot+Cool Formaldehyde HP09 Fan Heater. However, the Dyson Hot+Cool Formaldehyde is a lot more expensive and a lot slower at filtering the air than the 3000i Series. (Although, the Dyson's 3-in-1 air purification, fan and heater functionality may prove worth the investment for some).

If you have a smaller home then you may not need the Philips 3000i Series' powerful performance. In that case, the smaller Blueair Blue Max 3250i could be a better buy for you. 

But, if you have larger rooms or an open-plan home – or you're happy to invest a little more to benefit from the 3000i Series' super-efficient filtration – I think this Philips air purifier deal is a great opportunity to nab yourself a top-quality air purifier for less.

If I suffered from allergies or wanted to combat the effects of outdoor pollution in my home, it's definitely an air purifier deal I'd be snapping up myself.

Our Philips 3000i Series AC3033/30 Connected Air Purifier review puts one of the most powerful air purifiers on the market through its paces to see how it fares in comparison to the best air purifiers the Ideal Home team has tested.

Philips has a wide range of air purification devices in its roster, but the 3000i Series is the biggest and most powerful of the bunch, with a 520m³/h CADR (clean air delivery rate) and the capability of filtering the air in a space up to 135m².

That makes it a great option for use in large or open plan homes, where its HEPA and active carbon filter promises to make quick work of combatting 99.97% of airborne allergens.

It also features a built-in air quality sensor that gives you real-time readings of your home's Indoor Allergen Index, PM2.5, and gas (meaning VOC and odour) levels and an automatic mode that uses these readings to manage your home's air quality without manual intervention. 

Plus, Wi-Fi connectivity means you can view additional air quality data via the Philips Clean Home+ App and allows remote operation of the air purifier, either via a Smart device or by connecting the Philips 3000i Series AC3033/30 Connected Air Purifier to Amazon Alexa or Google Assistant for voice-activated control.

Overall, the 3000i Series has a lot to offer, so I was eager to put it to the test in my own home to see how it compared to the competition.

How I tested

Assembly and set up

The Philips Series 3000i Connected AC3033/30 air purifier arrives in a fairly sizeable box, measuring H71 x W35 x D36cm.

Once unboxed, assembly is fairly minimal, with just the back of the air purifier to remove so you can unpackage the substantial air filter and slide it back into the air purifier's cavity.

Beyond that, all you need to do is connect the Philips Series 3000i Connected AC3033/30 air purifier to your Wi-Fi and download the Philips Clean Home+ App if you want to operate it remotely via your preferred device. You can also connect the Series 3000i to Amazon Alexa or Google Assistant for voice-activated control. However, the Series 3000i can also be operated via the on-board controls if you're not that tech savvy.

Design

All in all, the Philips Series 3000i Connected AC3033/30 measures H64.5 x W29 x D29cm and weighs in at 6.8kg. Whilst that doesn't make it the largest air purifier I've tested, it does mean it's a model that you'll want to place on the floor rather than a work surface.

Its cylindrical design echoes the shape of most air purifiers on the market, although the fabric-covered upper third is a nice touch that makes it feel a bit less 'appliancey' and a little more like a piece of upholstered furniture, helping it to blend into the home. 

Overall, the design is reminiscent of a sound speaker, and it doesn't look too out of place popped in a corner of the room. 

The control panel is placed on the top of the air purifier, with a large circular LCD that displays the current IAI level, PM2.5 and gas levels. 

As well as a numerical value for each category, the outer edge of the LCD also changes colour to indicate the air quality level, switching from blue for 'good' air quality, through blue-purple for 'fair', purple-red for 'poor', and red for 'very poor' as the air quality drops.

Performance

The Philips 3000i Series can be operated in three modes – Auto, Turbo and Sleep. 

In Turbo mode the air purifier operates on its highest fan speed and in Sleep mode it stays on the lowest fan speed for its quietest performance, as well as dimming the lights on the LCD.

In Auto mode the air purifier uses its built-in air quality sensors to adjust the fan speed in accordance with the ambient air quality, switching up a gear should air quality drop and switching back down to standby when air quality is good. 

Auto is the mode I put the air purifier into to perform my first test of its filtering powers.

When I first turned the air purifier on, I was pleased to see it register very low levels of pollutants in all three of the available measurements; IAI, PM2.5 and gas.

To test out how quickly the Philips 3000i Series AC3033/30 Connected Air Purifier would pick up on changes to the air quality – and remove any offending airborne pollutants – I first lit a match a safe distance from the air purifier and let it burn out to create smoke in the air.

The 3000i Series registered the drop in air quality in a super fast three seconds, and then took 30 seconds to clear the air and return to standby mode.

I performed another test spraying aerosol deodrant in the vicinity of the air purifier to see how quickly it would register the VOCs present, and got the same super speedy results. This time it took the 3000i Series five seconds to register the airborne particulate and just over two minutes to return the air quality back to 'very good'.

Next up it was the cooking fume test. My kitchen has an ancient extractor fan that struggles to adequately remove cooking odours, so seeing if the 3000i Series could outperform it would be a good test of its powers. 

I shut the kitchen door, made sure the windows were closed, left the extractor fan off and started frying two rashers of plant-based bacon whilst the Philips 3000i Series was running in Auto mode and positioned a safe distance away.

From when the bacon first started sizzling, it took the 3000i Series another super speedy 40 seconds to register the cooking fumes, at which point the air quality indicator reading began climbing, the display light switched to red, and the fan speed increased in line with the fumes intensifying.

All in all, it took 11 minutes and 21 seconds for the 3000i Series to finish doing its thing, register the air quality as back to 'very good', and return to its lowest standby fan speed setting.

In each of these tests the Philips 3000i Series AC3033/30 Connected air purifier's performance was very impressive with it demonstrating super fast response times to each of the airborne pollutants.

Ease of use

The Philips 3000i Series is also super easy to use. The control panel is very intuitive and the LCD buttons clearly marked and easy to press, and the built-in sensors mean that you can switch into Auto mode and just let the air purifier do its thing.

The 3000i Series also offers more in-depth air quality data than most other air purifiers I've tested, beaten only by the super detailed air quality analysis of the Dyson Purifier Hot+Cool Formaldehyde HP09 Fan Heater.

And I loved how accessible that air quality data was. It just required a quick press of the onboard controls to see a detailed analysis of overall IAI, PM2.5 levels and VOC levels, with the option of even more detailed information within the Philips Clean Home+ App. Although it is worth noting I found some third-party reviews from users that mentioned some people had had problems with connecting to the App.

The coloured air quality display lights are also a nice addition, but having the numbered measurements alongside sets this air purifier apart from most of its competition in this regard.

Noise levels

Officially, the noise levels of the Philips 3000i Series AC3033/30 Connected Air Purifier measure between 15-56dB, depending on which mode you have it running in.

The higher the fan speed the noisier the airflow, but it is not often you'd have the air purifier running at full capacity, especially as the 3000i Series is equipped with that Auto mode which drops the fan speed back down to low as soon as any pollutants are filtered from the air.

The 3000i Series' Sleep mode is also a useful touch, meaning you can have the air purifier running overnight to steadily filter the air without any worries about being disturbed by an increase in fan noise.

Portability

Portability is one of the areas where the Philips 3000i Series AC3033/30 Connected Air Purifier could see some improvements. 

Although it is fairly weighty at 6.8kg, this wouldn't be too much of an issue if there was an easy way to grip the Series 3000i. But, its large cylindrical design doesn't come equipped with a carry handle, so trying to hold onto its smooth cylindrical body to move it without any handholds can be an issue. 

It's not impossible to do, but its manoeuvring would be made much easier with a folding handle built into the design.

Energy use

The Philips 3000i Series AC3033/30 Connected Air Purifier uses between 2-55W of energy depending on which fan speed the appliance is operating in.

That's definitely not as energy efficient as smaller air purifiers that average around 25W, but the 3000i Series' automatic mode does help cut down on running costs meaning you'll rarely need the air purifier on full blast for long. 

This energy-saving feature means that you can rely on the 3000i Series' built-in air quality sensor to automatically control the air purifier's performance, so you're never wasting more energy than you need to maintain good air quality.

You can find out more about how much it costs to run an air purifier in our dedicated guide.

Filter replacement

Air filter replacement is an additional cost that it's important to factor into any air purifier purchase.

On average most manufacturers advise that an air filter should be replaced roughly every six months as it will gradually become clogged up with particulate and its efficiency therefore reduced. However, the good news is that Philips suggests the 3000i Series AC3033/30's HEPA filter should only need replacing every three years.

No doubt this guide to replacement frequency will depend on how well you look after the filter, but the 3000i Series comes with a handy cleaning light that illuminates when the filter needs a little TLC, at which point Philips recommends gently cleaning it with a vacuum cleaner.

Another light will illuminate when the filter needs replacing, and handily you can press this at any time to view the filter's 'health' status, whereby a percentage showing the filter's remaining service life is displayed on the LCD screen.

When you do come to replace the filter, it looks like replacements are around £85, as of writing. Not cheap, but not the most expensive I've come across either, especially for an air filter of this high a CADR rating.

Verdict

Overall, I think the Philips Series 3000i Connected AC3033/30 is a great air purifier. It is an investment, and if you only have a small space to filter then you could save money by opting for a less powerful model – there are plenty of lower CADR Philips air purifiers available – but, if you have a large room or open plan home then this is a great air purifier for bigger spaces. 

In all of our tests, the 3000i Series responded fast and effectively, quickly identifying and filtering out a variety of airborne particulates. In fact its performance was on par with our two top-rated air purifiers, the Blueair Blue Max 3250i and AEG AX91-604GY Connected air purifier.

The Blueair Blue Max 3250i air purifier is a lot more affordable but has a lower 239m³/h CADR which means it can only filter the air in a space up to 48m2. So if you have a larger space to purify, then the 3000i Series 520m³/h CADR and 135m² is a better buy. 

However, it is just pipped to the post by the AEG AX91-604GY Connected air purifier which offers a super impressive 620m3/h CADR. Thanks to the AX91-604GY's carry handles the AEG is also slightly more portable and easier to move around the home, the AEG model also uses slightly less energy, but both are great options for a larger space. 

The easy-to-read air quality data the 3000i Series' provides is also almost unbeaten, with only the Dyson Purifier Hot+Cool Formaldehyde HP09 Fan Heater offering comparable detail. Although the Dyson offers far less powerful air filtration than this Philips model.

All in all, fast response times, powerful HEPA filtration, an easy-to-use design, great air quality data, and Wi-Fi connectivity make the Philips Series 3000i Connected AC3033/30 a great large space air purifier. And, I've often seen it available with significant discounts throughout the year. So keep an eye on our air purifier deals page, and you could snap it up for a bargain price.

If you struggle with mould in your home you will look for any way to stop it coming back. In your quest to achieve this you might be wondering does an air purifier stop mould? We’ve asked the experts to find out if the investment will help.

At Ideal Home, we’ve tested some of the best air purifiers on the market. And while this tried and tested appliance can certainly improve your air quality and remove airborne pollutants from the air, you might be wondering whether it can also get rid of damp in your home. After all, many of us struggle with excess moisture and mould in our homes as a result of poor ventilation, leaks, and cold weather. 

Left untreated, mould can prove detrimental to your house and your health. And while an air purifier might not be the mould solution you were looking for, you shouldn’t rule it out completely. Here’s why. 

Does an air purifier stop mould?

If you’re wondering how to get rid of mould on walls or how to clean mould off fabric, you’ll no doubt be familiar with the risks that come with having mould in the house. Ideally, you should get rid of mould as soon as possible, but does an air purifier stop mould?

Chris Michael, Managing Director of Meaco, explains, ‘An air purifier will not stop mould as this is a moisture-based problem, and you need to think about where that moisture is coming from. A dehumidifier would be best if the moisture is being created by normal lifestyle routines (bathing, showering, drying washing, cooking etc).’

In fact, the best dehumidifiers are perfect for those who have a moisture problem and want to get rid of damp. But sadly, an air purifier doesn’t work in that same way. 

Instead of drawing in and collecting the moisture from the air, an air purifier re-circulates the air while capturing airborne particles and pollutants in the process. This won’t reduce the moisture levels. 

However, that doesn’t mean that an air purifier can’t help those with mould problems. Chris adds, ‘Where an air purifier is useful is in capturing mould spores. These are the ‘seeds’ released by mould to help it spread and multiply. It is the mould spores that people are allergic to.’

This also means that if you tackle the damp problems in your home and remove the mould that’s taken over your house, an air purifier can stop mould from coming back and prevent it from spreading further. 

Of course, you should also make sure to use an air purifier if you are actively removing mould from your home. 

Lars Dunberger, Technology Development Manager at Blueair, explains, ‘Airborne mould particles have been shown to cause irritation in eyes, skin nose, throat, and lungs. During the cleaning process to remove mould from your environment, spores are likely to become airborne. To get rid of mould spores from indoor air, a high-performing air purifier certified for mould removal should be used.’

Doing this will pay off in the long run, though, and using an air purifier can also help to remove the mouldy, musty smell from your home. However, you need to take care of this appliance if you want to reap its mould spore and odour-removing benefits. 

Cristina Raboj, Global Proposition Manager at Philips, explains. ‘It’s important to remember that even if you do have an air purifier, you need to look after it, or its effectiveness will diminish. Changing the filter regularly is a simple bit of TLC that will help ensure it’s operating at peak efficiency in your home.’

‘But, to prevent mould in the long run, you have to tackle the cause at its source. Mould thrives in damp, dark moisture-rich places, so keeping your home as dry and well-ventilated as possible is key to preventing a build up.’

If you're looking for an air purifier that will help to remove mould spores from your home, we've picked a few of our favourites below. 

FAQs

Do air purifiers really get rid of mould?

Unfortunately, no. An air purifier cannot get rid of mould as mould is caused by a build-up of excess moisture in your home. To successfully get rid of mould, you’ll need to tackle the source of the moisture, clean the mould off, and use a dehumidifier to remove this excess moisture. 

An air purifier can prevent the spread of mould spores, though. This can ultimately prevent mould from spreading throughout your home and even improve the musty smell you may have in your house. 

How long does it take for an air purifier to remove mould?

An air purifier will not get rid of mould, but it can capture mould spores. Depending on the magnitude of the problem, an air purifier can trap these mould spores in as little as 30 minutes. 

However, you’ll need to tackle and get rid of the mould to stop these mould spores from returning. 

Is a dehumidifier or air purifier better for mould?

Experts agree that the best appliance for mould is a dehumidifier, as this appliance can successfully reduce the moisture levels in the home and prevent mould from getting worse. But, like an air purifier, a dehumidifier won’t get rid of mould. It’ll just help to remove the excess moisture from the air, which can stop it from spreading and affecting your home even more. 

An air purifier might not stop mould, but it’s still an appliance you need on your radar. 

If you feel like you’re constantly dusting your house, you might be wondering whether an air purifier stops dust. To answer this question once and for all, we’ve consulted with the experts. 

At Ideal Home, we’ve had the pleasure of testing the best air purifiers on the market, and while we’re impressed by the best houseplants that can reduce dust, nothing comes close to the cleaning powers of the air purifier. This nifty appliance can rid your home of airborne pollutants and help you breathe easily throughout the year. But can they stop dust completely?

With the help of industry experts, we're happy to report that air purifiers can indeed affect the dust levels in your home. However, with good news comes a little bit of bad news, so you probably shouldn’t retire your feather duster just yet. 

Does an air purifier stop dust? 

If you’re wondering whether an air purifier stops dust, it’s important to realise that this question has a two-pronged answer. On the one hand, an air purifier does help to remove dust from your home, and it's one of the unexpected perks of this handy appliance. But there is a caveat to this. 

Chris Michael, Managing Director of Meaco, explains, ‘An air purifier will not stop the creation of dust, but it will help to capture dust that is within the air and within its reach.’

That’s because an air purifier is designed to filter and capture airborne particles, dust, and pollutants in your home. In doing this, you can be sure that you’re breathing in clean, pure air - which is particularly important for those who struggle with asthma or allergies. 

Quality is key when it comes to air purifiers and dust, though. Joshua Warren, air purifier expert at AO.com, suggests buying a specific air purifier for this job. 

‘If you’re looking to tackle dust, then look out for air purifier models with HEPA (high-efficiency particulate air) filters,’ he explains. ‘These filters are highly efficient at capturing dust particles, so be sure to move this from room to room to help remove any dust buildup in your home.’

This means that, as long as you have the right air purifier for your home, this handy appliance can remove dust from your home. But that doesn’t mean that it won’t come back. 

Unfortunately, it’s impossible to stop the formation of dust in your home. Every time you walk outside and bring your shoes back indoors, you’re bringing dust into the house. Every time your dog shakes its head, it’s adding more dust to your house. In fact, even using the best vacuum cleaner can contribute to this extra dust. 

This is something that I’ve (unofficially) tested myself with my Philips Series 800 AC0820/30 Air Purifier, which monitors the air quality in real time. The display on the top of the air purifier changes colour based on the air quality (blue = good, purple = fair, pink = poor, red = very poor), and the fan speed will automatically adjust itself with this knowledge. 

During my test, I checked the display before and after vacuuming my living room - and it actually got worse. Before I vacuumed, my air quality was fair. When I finished vacuuming, I noticed the fan speed had increased, my air quality had changed to poor, and the colour had changed to pink.

Thankfully, it only took around five minutes for the air purifier to work its magic and for the air quality to improve again, but I can only assume that the act of vacuuming disrupted the dust on my floor and on my rug and thrust it into the air. 

And if I didn’t have an air purifier, I would be breathing in that extra dust without even realising it. So, I can deny that it’s definitely a purchase I’m thankful for. 

But Chris wants people to realise that an air purifier isn’t a complete solution for dusting. He says, ‘It is not a replacement for dusting, though, and there will be some left in areas that are outside of its influence.’ In fact, that’s why you should always research the specs of the air purifier you want to buy and work out how many air purifiers you need to cover the entirety of your home. 

Keeping on top of your cleaning is seconded by Cristina Raboj, Global Proposition Manager at Philips, who says, ‘I would recommend keeping up with regular dusting at least once a week to get rid of those extra-large bits of dust before they can become an issue.’

‘By doing this, you’ll be giving your air purifier the helping hand it needs and will be breathing more easily in no time.’ 

The best air purifiers for dust - our top picks

If you're looking for an air purifier that can help to reduce dust in your home, we've put together a few of our favourite picks below. 

FAQs

Do air purifiers really reduce dust?

Yes, air purifiers are designed to remove dust particles from the air. However, it’s important to realise that it cannot stop the formation of dust, and it’s unlikely that an air purifier will remove dust from your home completely. 

Because of this, it’s important to maintain a continued cleaning schedule of dusting and vacuuming your home, as well as using an air purifier.

Should I get an air purifier if my room is dusty?

Air purifiers are certainly a worthwhile investment, especially if your home is particularly prone to dust. These appliances are designed to remove allergens, pollutants, and dust from the air and can certainly help to reduce the amount of dust in your home. 

Just remember to keep on top of your air purifier maintenance, which involves cleaning or replacing the filter as recommended by the manufacturer. If you don’t, the air purifier will struggle to work to the best of its ability, and it may struggle to remove dust particles from the air. 

How long does it take for an air purifier to remove dust?

This all depends on the size of your room or home, your air quality, and the quality of the air purifier itself. If you don’t have a dusty home, the air purifier could work its magic in as little as 30 minutes. If you do have a dusty home, it could take longer and may even take over two hours to remove the dust from your home. 

With this in mind, we’re starting to wonder if there’s anything an air purifier can’t do. 

If you're looking for a budget air purifier, then this Beko ATP5100I Air Purifier review puts one of the most affordable air purifiers on the market through its paces. 

The Beko ATP5100I is a compact and lightweight air purifier with a relatively low CADR (clean air delivery rate) of 110m3/h that's designed for use in spaces under 13m².

In line with its budget price tag, the Beko ATP5100I offers basic functionality with just three fan speeds, a timer that can be set in two, four or eight hour intervals, and an optional ionisation function. 

Unlike air purifiers that are two or three times the ATP5100I's price, it doesn't offer a built-in air quality sensor, and there's no automatic or 'smart' functionality. That means that whereas of the best air purifiers on the market take the hassle out of managing indoor air quality by using a sensor to monitor pollution levels and automatically switch the purifier on and off to maintain optimum air quality, with the Beko ATP5100I it's up to you to decide when to turn the purifier on or off, and you don't get any visible gauge to show you when air quality is improved. 

The Beko ATP5100I also doesn't offer any Smart features, so there's no App to give you air quality readings, and it can't be controlled with voice commands via Alexa or Google Assistant.

However, if you're after a budget air purifier, it may be that this additional functionality is something you're willing to sacrifice, so we put the Beko ATP5100I Air Purifier to the test to see how it performed.

How I tested

Assembly and set up

There's very little assembly or set-up needed with the Beko ATP5100I Air Purifier, you simply need to unbox it, twist off the top section, and remove the PE bag from around the air filter inside the appliance before securing the top of the purifier back into place. 

As this air purifier doesn't have Wi-Fi connectivity there's nothing you need to connect, and no Smart Apps to download, all functionality is managed using three buttons on the top of the purifier.

Design

Compared to some air purifiers, the design of the Beko ATP5100I Air Purifier is pretty basic, but its cylindrical form is still pleasant enough to look at, and its relatively compact size means it's pretty unobtrusive in a room. 

The lower two-thirds of the air purifier are taken up by the air filter which is housed behind a matt white metal grill with lozenge-shaped perforations to allow the air to flow in.

Filtered air is then expelled via the top of the air purifier, where you'll also find the ATP5100I's three control buttons that turn the air purifier on and off, allow you to set a timer, or alter the fan speed.

The lack of functionality does make the Beko ATP5100I Air Purifier feel more basic than many of its more expensive counterparts, and I definitely missed having a visible air quality indicator built in to the air purifier so I could see what the current air quality was at a glance. But, that reduced functionality is reflected in the Beko's budget price tag.

Performance

The Beko ATP5100I Air Purifier offers a relatively low CADR (clean air delivery rate) of 110m3/h and is designed for use in spaces under 13m², so it's one of the lowest capacity air purifiers I've tested – understandably, as it's also the cheapest air purifier I've reviewed. 

It features three fan speeds that you can adjust manually via the controls at the top of the air purifier, however, what it lacks in comparison to more expensive air purifiers, is an automatic mode. 

The lack of this feature is what makes the Beko ATP5100I able to offer air purification with a budget price tag, however, to my mind it is quite a big loss in functionality. 

An air purifier with an automatic mode uses a built-in air quality sensor to measure the air quality, and then uses this data to automatically control the air purification process accordingly, without user input. For example, if the air quality suddenly dips, then the air purifier will sense this and turn itself on to filter the air and return your room's climate to best possible air quality as quickly as possible.

Because the Beko ATP5100I Air Purifier doesn't have this feature, it's up to the user to determine the air quality level and decide when to turn the air purifier on and off. This can prove tricky, as in practice that either means relying on your nose or your allergies to alert you to a dip in air quality – not always the most reliable method as many airborne pollutants don't have odours. Alternatively, you'll need to leave the air purifier running constantly, which – even though the ATP5100I isn't particularly energy hungry – could still rack up your running costs.

However, one thing that most of us can easily identify is the fumes from frying bacon! So this was the first test I put the Beko ATP5100I Air Purifier through to test its filtration powers.

All of the air purifiers with automatic modes that I've tested switched into their highest fan speeds once they'd detected bacon frying fumes, so I gave the Beko air purifier a headstart and began running it on its highest fan speed as soon as the bacon hit the pan.

After about 4 minutes the bacon had crisped up, so I then left the Beko purifier running whilst I tucked into my bacon butty. In previous tests, air purifiers with a built-in air quality sensor showed that the kitchen had been cleared of frying fumes in about 10-15 minutes, so I left the Beko purifier doing its thing for quarter of an hour, and then re-entered the kitchen to see if I could still smell bacon. 

Although there was a noticeable reduction in the bacon fumes, there was still a lingering smell in the kitchen – more so than with other air purifiers I'd tested. However, some of this smell also seemed to be a plasticky odour emanating from the Beko air purifier itself. 

I plugged in a different air purifier that comes equipped with an air quality sensor to see how the Beko had performed, and the air quality reading came back as 'very good', so the Beko had obviously done its thing with regard to removing any polluting particles, but, to my nose at least, the air in the kitchen didn't smell as fresh as it had when I performed this test with alternative air purifiers. 

Beyond the three fan speeds operated by the controls on the top of the purifier, the Beko ATP5100I Air Purifier also features an optional ionisation feature that you turn on by lifting off the top of the air purifier to adjust the on/off ionisation rocker switch. Beko says that this feature 'releases negative ions into outgoing filtered air to help the air purification process'. 

I tried the bacon test again, but this time with the ioniser switched on, to see if it made any difference. Again, most of the bacon fumes were removed, and the air quality independently verified as 'good' but still the same lingering smell from the air purifier itself remained. 

I also put the Beko ATP5100I Air Purifier through our smoke and VOC test, by allowing a match to burn out next to the air purifier and spraying deodrant nearby to see if it removed both odours. 

Overall, the Beko ATP5100I Air Purifier did do the job of improving air quality and removing impurities, but, understandably, it was less impressive in its performance than more expensive air purifiers that offer advanced functionality and higher CADR rates.

Ease of use

In terms of its controls, the Beko ATP5100I Air Purifier is very simple to operate because there are only three buttons to the top of the air purifier. 

These are touch sensitive and illuminate when selected to show you which functionality is engaged. You simply need to press the fan speed button repeatedly to toggle through the three fan speeds, and the same with the timer button to move through the three timer interval options. 

The ionisation on/off rocker switch is more awkward because you need to remove the top of the air purifier to access it, but I presume the idea is you'll only need to decide whether this functionality is one you want to employ once, and then you can leave it set either on or off.

What's less 'easy' in terms of ease of use, is the ATP5100I's lack of a built-in air quality sensor and lack of automatic filtering mode. This puts the responsibility for air quality management onto the user, rather than it being managed by the air purifier itself. An air purifier with an automatic mode will cost more upfront, but, in my opinion, it's well worth it for the hassle-free experience and the improved air quality control.

Noise levels

Beko doesn't give any official noise level data, but my ears estimated that despite its compact size, the Beko ATP5100I Air Purifier was one of the noisiest air purifiers that I've tested. It's quiet on its lowest fan speed setting, somewhat noisy on its middle fan speed, and definitely noisy on its highest fan speed setting.

It would be very possible to have it running on its lowest fan speed during the night if you wanted to use it in a bedroom without disturbing your sleep, but I wouldn't personally want to sleep with it on whilst it was operating on either of the faster two fan speeds.

Portability

A compact and lightweight build that measures H38 x W20 x D20cm and weighs in at 2.3kg means this is the smallest, and therefore most portable, air purifier I've tested. 

It's a shame it doesn't come with a carry handle, but as long as you're able to grip its cylindrical body with two hands, then it's very easy to move.

Its compact design also means it's great for smaller rooms where you might be short on floorspace as it's small enough to be tucked onto a work surface, desk, or even a shelf as long as there's enough space for air intake from 360 degrees.

Energy use

In keeping with its compact size and low CADR, the Beko has very low energy usage, relatively speaking. 

Whereas most air purifiers average 20W-55W of electricity to run, the Beko ATP5100I Air Purifier uses just 10W. 

However, sadly that's not all good news. As this air purifer doesn't have an automatic function, that means it's either on or off. So if you want your air quality to be managed continuously that means leaving the ATP5100I running constantly, which isn't a great use of energy and could mean higher running costs.

You can find out more about how much it costs to run an air purifier in our dedicated guide.

Filter replacement

The Beko ATP5100I Air Purifier is a very affordable buy upfront, however, as with all air purifiers, you do also need to factor in the ongoing cost of buying replacement air filters.

Generally manufacturers advise that an air filter should be replaced roughly every six months as it will gradually become clogged up with particulate and its efficiency therefore reduced. 

Beko doesn't give a recommended timescale for air filter replacement, but there is an indicator light that will come on when the filter needs replacing. When that time comes, replacement filters cost around £20, as of writing. 

That's cheaper than most, with the average filter replacement cost for an air purifier of this size around £35, and larger air purifiers carrying air filter replacement costs of up to £100!

Verdict

In my opinion, the main selling point of the Beko ATP5100I Air Purifier is its price. At well under £100, it's an affordable air purifier with relatively cheap ongoing costs thanks to its reasonably priced air filters. 

However, the ATP5100I's budget price tag is only made possible due to its low CADR, less powerful filtration meaning it can only purify the air in a space under 13m2, and its basic functionality. Most notably, that affordable price ticket means a lack of built-in air quality sensor, a lack of automatic mode, and a lack of Wi-Fi connectivity. 

Unless you need an air purifier that can be operated remotely via an App, or connected to a voice-activated device, or you want the detailed air quality insights that tend to come with Smart App integration, then the lack of Wi-Fi connection might be 'nice to have' that's worth sacrificing to save money.

However, in practice, I found the lack of air quality sensor and automatic mode a real hindrance to air quality management, and in some ways a false economy. If you can, I think it's well worth paying extra for a model – like the Blueair Blue Max 3250i Air Purifier – that has both of these features so that you can sit back and let the air purifier do its thing. Automatic mode also means lower energy usage and therefore reduced ongoing running costs.

That said, if affordability is the main criteria in your search for an air purifier, and as long you don't have a space larger than 13m2 (if you do, then the AEG AX91-604GY Connected Air Purifier is our top choice for filtering large spaces and open-plan homes), then the Beko ATP5100I Air Purifier does do the job. 

You can whack the ATP5100I on whilst cooking dinner, when grass pollen is at its peak, or in a smoky environment, and, it will help to clear the air. It's just a shame that you don't get any air quality data – beyond your own nose or itchy allergy-prone eyes – to help you ascertain when to turn the Beko ATP5100I Air Purifier on and when to turn it off.

Our AEG AX91-604GY Connected Air Purifier review puts the brand's highest-specced air purifier through its paces to see how it compares to the best air purifiers the Ideal Home team has tested.

The AX91-604GY is designed for use in large spaces, with the brand stating it can filter the air in a room measuring up to 129m2. It does this by way of a 5-stage purification process that utilises a pre-filter, an antibacterial layer, a pre-charged True EPA12 filter, an active carbon filter and an optional ionisation function.

The AX91-604GY has a very impressive clean air delivery rate of 620m3/h (that's CADR for short, a measurement which describes the volume of clean air an air purifier produces per minute) which is nearly three times that of smaller air purifiers we've tested. However, the AX91-604GY also has an impressive price tag to match. 

So is the AEG AX91-604GY Connected Air Purifier worth the investment? Having put it through its paces in my open-plan living/dining room, I certainly think it's a great air purifier for use in large rooms and open-plan spaces. Read on to find out why.

How I tested

Assembly and set up

There's very little assembly needed with the AEG AX91-604GY Connected Air Purifier. Once it's unboxed you simply need to pull out the air intake door at the back of the purifier so that you can remove the protective plastic packaging from around the air filter. 

This is made easy thanks to a fabric handle that you pull outwards to remove the door. Magnets then help to hold the door in place when you reposition it onto the purifier afterwards.

Beyond that, all the set-up you need to do is download the AEG Wellbeing App if you want to make the most of the air purifier's Smart features or connect it to Google Home if you want to integrate it into the rest of your home's Smart tech. 

However, the AX91-604GY can also be operated via the onboard controls on the top of the unit with only a little sacrifice of functionality. 

One of the few functions that can only be operated via the App is the ionisation function. AEG states that this optional ioniser function 'produces negatively charged particles (negative ions) using electricity' which the AX91-604GY then 'pushes out into the room to attach themselves to oppositely charged particles in the air – such as dust, bacteria, viruses, pollen, smoke, or other allergens – making them bigger, heavier particles that either attach themselves to surfaces including the ground or are captured by the filters of the air purifier on the subsequent run(s), thereby eliminating them from airborne circulation'.

If you want this feature turned on you just need to toggle the setting in the AEG Wellbeing App.
 

Design

The AEG AX91-604GY Connected Air Purifier is a stylish device, which is good news because its H72.5 x W31.5 x D31.5cm measurements mean it's going to become a bit of a focal point in any room you use it in.

Its height means that this is an air purifier that's better sat on the floor rather than a surface, but considering its overall size, its 31.5cm diameter footprint isn't too space-hungry.

And, from the moment you unbox it, the AEG AX91-604GY Connected Air Purifier feels like a quality appliance. As I've come to expect from the German-founded brand after previously testing a few other products, there are some nice design touches that instantly make AEG's AX91-604GY feel like a premium product.

The lower half of the AX91-604GY houses the air filter, which is protected by hexagonal honeycombed metal that's finished in matt grey – none of the plastic bodywork that's common with cheaper air purifiers – and the upper half is finished in a tonal grey fabric.

The metal grill and the fabric upper both help to soften the appearance of the AX91-604GY so it feels far more like a considered piece of furniture than an unsightly appliance plonked in the middle of a room, and the tonal shades of grey cleverly help its relatively large form not to feel as bulky as it otherwise might.

The robust leather (or leather-look, I couldn't find material details listed) carry handles on either side of the appliance are also a nice touch that adds to the AX91-604GY's minimal yet luxe styling.

And then there's that distinctive hexagonal air outlet at the top of the air purifier that makes the AX91-604GY stand out from the crowd. 

Bang in the centre of this is the touch-sensitive digital control panel which offers by far the most intuitive and user-friendly interface of any air purifier I've tested so far.

The control panel features an on/off button and a Mode button that allows you to toggle between Manual or Smart mode. 

The Manual setting allows you to manually adjust the fan speed, which you do by swiping your finger over the illuminated arc that's displayed on the control panel. The more of the arc that's lit up, the higher the fan speed. In Smart mode, the air purifier uses the readings of the built-in air quality sensor to choose the appropriate fan speed automatically.

In both of these modes, the underneath of the hexagonal control panel lights up in one of six colourways to communicate the current air quality. There's green to indicate 'very good' air quality of 0-12 PM2.5, yellow indicating 'good' and a range of 13-35 PM2.5, orange for a 'poor' reading of 36-55 PM2.5, red for 'very poor' 56-150 PM2.5, purple for 'bad' 151-250 PM2.5, and maroon for a 'very bad' air quality reading of over 250 PM2.5.

Using the AEG Wellbeing App also gives you more detailed air quality data, and allows you to continue to monitor your home's air quality when you're out of the house.

Performance

Having been well and truly wooed by the AX91-604GY's digital LED display panel, I was eager to put the purifier to use to see how its clever controls worked in practice.

The AX91-604GY's Smart mode is a great feature that means you can save on energy by only using the fan speed necessary to clean the air, and this is the mode I put the air purifier into to perform the first test.

I was happy to see that when I first turned the air purifier on it displayed the green indicator light, communicating that the indoor air quality was currently in the 'very good' range.

To test out if it could pick up on changes to the air quality, I lit a match close to the air purifier and let it burn out to create smoke in the air. 

In Smart mode it took the AEG AX91-604GY Connected Air Purifier around 30 seconds to register the smoke particles and for the air quality indicator light on the top of the display to change from green to red. That meant the purifier had registered a drop to 'very poor' air quality so the appliance automatically increased the fan speed to return air quality to 'very good'. 

All in all, it took 4 minutes 28 seconds for the AX91-604GY to clear the air and return to standby mode, shifting through orange (poor), yellow (good) and then back to green (very good) air quality. I left the room and then re-entered to see if my nose agreed with what the AX91-604GY was registering and I couldn't smell any trace of smoke at all when I returned. Impressive stuff, and one of the best results from all the air purifiers I've so far put through the smoke test.

When I tested spraying aerosol deodorant in the vicinity of the air purifier the results weren't quite as positive. It took around 30 seconds again for the AX91-604GY to register the VOCs present in the deodorant, and although the fans did ramp up a gear, they only ran for 48 seconds before the AX91-604GY returned to standby. I tried the test again but got very similar results, which meant there was still quite a strong smell of deodorant left in the air.

I also tested the AEG AX91-604GY Connected Air Purifier in the kitchen to see how it coped with cooking fumes. My kitchen has a very old extractor fan that struggles to adequately remove cooking fumes, so I was interested to see how the air purifier would perform in comparison. 

To test out its powers I shut the kitchen door, made sure the windows were closed, left the extractor fan off and started frying two rashers of plant-based bacon whilst the AEG AX91-604GY Connected Air Purifier was running in Smart mode and positioned a safe distance away.

From when the bacon first started sizzling, it took the AEG AX91-604GY Connected Air Purifier 3 minutes and 48 seconds to register the cooking fumes, at which point the air quality indicator shifted through the colour spectrum to maroon, and the fan speed increased in line with the fumes intensifying.

By the time the AEG AX91-604GY swung into action the bacon had just about finished crisping up, so I snuck out of the kitchen, shut the door again, and set to work eating my bacon sandwich. All in all, it took 11 minutes and 48 seconds for the AX91-604GY to finish doing its thing, register the air quality as back to 'very good', and return to its lowest standby fan speed setting.

At this point, I re-entered the kitchen to see if my nose agreed with the AX91-604GY, and although there was still a faint smell of bacon, it was far less noticeable than it would have been had I been reliant on my not-very-efficient extractor hood or an open window during the frying process.

Lastly, there was the dust test to perform. Whilst the AX91-604GY was in Smart mode I emptied the contents of my vacuum cleaner onto the floor next to it. The air quality indicator remained a constant green for 'very good' air quality throughout this process – a bit of a surprise as I was expecting it to immediately register the dust particles floating around in the air before and after the dust settled as impurities and swung into action.

When I manually set the air purifier to its highest fan speed and performed the same exercise, I could see the dust particles being drawn into the air purifier's filter, but again the indicator light didn't show a decrease in air quality.

Seeing as the AEG AX91-604GY draws in air from 360°, it may be that the bulk of the air it was filtering was non-dusty and therefore overall the air quality remained high throughout the exercise. However, on higher fan speeds the dust was visibly being drawn into the purifier, which I guess is what counts! 

And, when the ioniser function was turned on via the Smart App, it may be that airborne dust particles were made heavier and sank to the ground, as AEG states will occur.

All in all a slightly mixed set of results, with the AEG AX91-604GY not quite as quick to react in the deodorant and cooking tests as the super-responsive Blueair Blue Max 3250i air purifier that I've previously reviewed, but producing very impressive results in the smoke test. Although in all tests the AX91-604GY certainly improved air quality considerably.

However, what was very clear from my testing was how well the AEG AX91-604GY could perform in a large space. I have an open-plan living and dining room, and smaller air purifiers I've tested, like the Blueair Blue Max 3250i and Levoit Core 300S air purifier, have struggled to filter the air in this larger space. However, the more powerful AX91-604GY took it all in its stride. 

That's perhaps no surprise as the AX91-604GY is specifically designed for use in rooms up to 129m2, and its 620m3/h CADR is nearly three times higher than that of the Blueair Blue Max 3250i and Levoit Core 300S.

To filter the air in a larger space, the AX91-604GY features what the brand dubs an 'AirSurround system', saying this 'creates a powerful yet smooth spiral movement of the indoor air that efficiently circulates and cleans the air'. And it certainly seems to work. 

In contrast to the smaller air purifiers I've tested, I could feel the air gently moving quite some distance from the AX91-604GY, with the powerful fan and spiral air outlets at the top of the air purifier ensuring the air circulated to all four corners of the largest room in my house.

Ease of use

The AEG AX91-604GY Connected Air Purifier is very easy to use, offering a touch-sensitive display that's responsive in all the right ways and a pleasure to use. 

It's also super simple to operate and gets full marks from me for user-friendly design. In fact, this is the most user-friendly air purifier I've tested in terms of ease of use.

The Manual swipe feature is especially fun to operate, so it's perhaps wise that the air purifier also comes with a Child Lock function you can activate either via the App or by long pressing the On/Off and Mode buttons simultaneously to ensure no one gets swipe-happy!

Noise levels

The AEG AX91-604GY Connected Air Purifier's noise rating is pretty low, officially measuring between 17-32dB, dependent on which fan speed it's operating in.

Like every air purifier I've tested, the AX91-604GY is still pretty loud on its most powerful fan setting, although it's not an unpleasant noise, just the sound of gushing air. However, hopefully, it's not that often you'll need the air purifier running on maximum, especially if you have it operating on Smart mode, whereby it kicks into the highest gear should air quality drop, but will remain on the far quieter low and medium fan speeds for the majority of the time. 

The great thing about the AX91-604GY's Manual mode is that the fan speed arc offers a lot of versatility in fan speed choice. Whereas most air purifiers only offer three-speed settings, the AX91-604GY delivers a far wider breadth of speed options so you can tweak its operation to whatever noise level you feel most comfortable with.

The only thing the AX91-604GY seems to lack that its competitors provide is a dedicated Night mode. On alternative models, the Night mode drops the fan speed of the air purifier to below its normal lowest fan speed setting whilst Night mode is activated. The AX91-604GY doesn't seem to offer this functionality specifically, but as mentioned above, the Manual fan speed arc allows much more control over the fan speed you choose anyway, so it's easy enough to create your own 'Night mode' and set the AX91-604GY to its lowest fan speed at bedtime so it doesn't disturb your sleep. 

I'm a light sleeper, but I found the white noise of the AX91-604GY easy to ignore when left running in the bedroom overnight.

Portability

A lot of consideration has clearly gone into its design to make the AX91-604G feel a lot less bulky than it might otherwise do, but, there's no denying it is still a relatively large, heavy, and cumbersome device. 

Measuring H72.5 x W31.5 x D31.5cm with a weight of 8.9kg, whilst this air purifier is portable, I certainly didn't find it was a model I wanted to move that often. 

When you do come to transport it from one room to another, the leather-look carry handles work well. But I still found its height made it a bit of a struggle to manoeuvring the appliance up or down the stairs. Unlike more compact designs, I couldn't envisage regularly moving this purifier from the kitchen to the bedroom in a two-storey home.

However, if you want to improve the air quality in a large room or an open plan home, then the AEG AX91-604GY Connected Air Purifier is a great choice. In this scenario, you can just leave the air purifier in situ and let the cleverly designed spiral 'AirSurround system' on the top of the unit, and the AX91-604GY's powerful fan motor, bounce air around the room to ensure filtered air reaches all four corners of your interior.

Energy use

The AEG AX91-604GY Connected Air Purifier uses between 4-41W of energy depending on which fan speed the appliance is operating in.

Whilst that's not as energy efficient as smaller air purifiers that average around 25W, it is still fairly low considering the air purifier's size and power. 

The AX91-604GY's Smart mode is also a great energy-saving feature. The fact that you can use the built-in air quality sensor to automatically control the air purifier's performance means that you're never wasting more energy than you need to maintain good air quality.

You can find out more about how much it costs to run an air purifier in our dedicated guide.

Filter replacement

The downside of pretty much every air purifier is that beyond the initial purchase price of the purifier itself, you also need to factor in the ongoing cost of replacing the air filter every so often. 

Generally, manufacturers advise that an air filter should be replaced roughly every six months as it will gradually become clogged up with particulate and its efficiency therefore reduced. 

AEG doesn't give specific guidelines for how often the AX91-604GY filter should be changed, but there's a warning light that illuminates when this is necessary. You can also track the filter's usage in the AEG Smart App. 

When you do come to replace the filter there are four options to choose from. There's the original 'Breeze' filter that the purifier comes fitted with as standard, and then three additional filters that focus on removing odour, pollen, or bacteria and viruses.

However, these filters aren't cheap. The smaller air purifiers we've tested tend to average around £30 for replacement filters, but the AEG AX91-604GY is a large air purifier capable of cleaning the air in large rooms, and as such its filters are pretty sizeable too. That means a replacement AEG AX91-604GY filter will set you back around £100 as of writing. Ouch.

Verdict

Overall, the AEG AX91-604GY Connected Air Purifier is one of the best air purifiers for large spaces that I've tested. So, if you have large rooms or an open-plan home, then this could well be a great choice for you. 

That powerful fan, high CADR, and spiralling 'AirSurround system' do a great job of circulating the air in a large space to make sure the AX91-604GY is filtering every corner of the room. And it has a sizeable air filter with 5 stages of air purification to clean that air when it reaches the purifier.

The Smart mode is a brilliant feature that makes managing air quality super simple, the AX91-604GY is quiet on all but its highest fan speeds, and its controls are a dream to use, offering the best and easiest user experience of any air purifier I've tested. 

The air purifier's six-colour air quality indicator is also a great touch, as is the fact the machine is Wi-Fi compatible and can be paired with AEG's Wellbeing App for extra air quality data and functionality, as well as offering integration with Google Home.

The AEG AX91-604GY Connected Air Purifier's stylish design is another plus point. 

However, its premium feel is matched by a premium price point. This air purifier is a significant investment upfront, and although relatively low energy usage and that power-saving automatic mode mean running costs are fairly low, you do need to factor in the ongoing cost of those expensive replacement air filters. At £100 a pop as of writing, they certainly aren't cheap.

And, whilst a lot of consideration has gone into the AX91-604G's design to make it feel a lot less bulky than it might otherwise do, it is still a large and cumbersome appliance in the grand scheme of things. 

To my mind, this is an air purifier built for use on one level of the home rather than an appliance you'll want to carry up and down the stairs frequently. 

If you have a home with small rooms the AX91-604G probably isn't your best option – in that case, I'd recommend the less powerful but far more compact Levoit Core 300S air purifier or the mid-sized and super-responsive Blueair Blue Max 3250i air purifier instead. 

However, with the AEG AX91-604GY Connected Air Purifier powerful enough to filter the air in spaces up to 129m2, it is the perfect option for a one-level apartment, open-plan home, or any house with large rooms.

Our Blueair Blue Max 3250i air purifier review puts one of the popular air quality brand's newest models through its paces to see how it compares to the best air purifiers the Ideal Home team has tested.

Founded in Sweden, Blueair is part of the Unilever family of brands, and now sells air purifiers in over 60 countries, with a large product range that includes the bestselling Blue 3210 air purifier. 

The 3250i is a new and improved upgrade that, in comparison to the 3210, now offers Wi-Fi connectivity that enables you to access a wider range of air quality data via the Blueair App, as well was the ability to pair the air purifier with Amazon Alexa or Google Assistant if you prefer to use voice activated commands.

The Blue Max 3250i also offers improved filtration compared to the 3210. Blueair says it has 'maximized the area of the air filter and improved hole patterns for better performance that offers a higher Clean Air Delivery Rate (CADR) to filter out more smoke, dust and pollen in cubic feet per minute'. 

As opposed to the 3210's 163 m³/h CADR for pollen, 181 m³/h CADR for dust, and 210 m³/h CADR for smoke, the Blue Max 3250i now delivers a 239 m³/h CADR for all of these particulates, and its slightly larger design means it can purify a larger space (48m2 compared to the 3210's 41m2).

Unlike many air purifiers that only promise filtration of 99.97% of 0.3 micron air pollutants, the Blue Max 3250i also promises to remove 99.97% of airborne particles down to 0.1 micron in size. I put it to the test to see how it performed in practice.

How I tested

Assembly and set up

The good news is that there's very little assembly needed with the Blueair Blue Max 3250i Air Purifier. Simply unbox it and it's ready to use.

You can download the Blueair App if you want to make the most of the air purifier's Smart features, or connect it to Amazon Alexa or Google Assistant if you prefer to use voice activated commands. 

However, the Blue Max 3250i can also be operated via the on-board controls on the top of the unit with only a little sacrifice in functionality.

Design

Stylish and minimalist, the Blueair Blue Max 3250i Air Purifier looks a lot more attractive than most air purifiers, and just like the rest of the Blueair range, it's clear that a lot of thought has been put into its appearance. 

My favourite feature is the removable fabric knit cover that encases the lower two thirds of the air purifier. And that cover isn't just for looks, it also works as the air purifier's pre-filter, preventing large particles of dust and hair from entering the HEPA filter underneath. 

This cover can easily be removed and washed, and also replaced with one of the other four colour options that are available. Although, personally, I think the grey 'Stockholm Fog' cover that comes as standard is a great versatile colourway.

The Blue Max 3250i also features an indicator light on the front that automatically changes through five colourways to let you know the current air quality. Blue means 'excellent' air quality, green 'good', yellow 'moderate', orange 'polluted', and red 'very polluted' air quality. The coloured air quality indicator light is a really nice feature, although it would be good if the light was bit larger, as it's not that easy to see compared to some other models.

Similarly, I would also have liked the Blue Max 3250i's on-board controls on the top of the unit to be a little larger. Considering the size of the air purifier, they feel a little bit too small and could have been made easier to read.

All in all though, the design of the Blue Max 3250i looks great. The air purifier becomes something of a style statement in whatever room it's placed in, and certainly isn't an appliance you feel the need to hide away out of sight.

Performance

The Blueair Blue Max 3250i offers three fan speeds that you can set manually, as well as a Night mode, and a very easy-to-use Auto mode.

When the Auto setting is chosen the air purifier uses its in-built sensors to adjust the fan speed automatically based on air quality. For example, if the air quality is bad then the fan will automatically be set to high fan speed.

This is a great feature as it means you can save on energy by only using the fan speed necessary to clean the air, and this is the mode that I put the air purifier into to perform the first performance test.

I was happy to see that when I first turned the purifier on it showed a blue light on the indicator display, communicating that the indoor air quality was currently in the 'very good' range.

To test out if it could pick up on changes to the air quality, I lit a match close to the air purifier and let it burn out to create smoke in the air. In Auto mode it took the Blue Max 3250i 20 seconds to register the smoke particles and for the indicator light to change from blue to orange. That meant the purifier had registed a drop in the air quality so it automatically increased the fan speed to return air quality to 'very good'. 

All in all it took 2 minutes and 30 seconds for the Blue Max 3250i to clear the air and return to standby mode, shifting through yellow (moderate), green (good) and then back to blue (very good) air quality. 

When I left and then re-entered the room my nose couldn't pick up any trace of smoke remaining.

The same happened when I tested spraying aerosol deodrant in the vicinity of the air purifier. It took 20 seconds again for the Blue Max 3250i to register the VOCs present in the deodrant, and this time the indicator light displayed red for 'very polluted' air quality and soon got to work extracting.

This time the air purifier took 2 minutes and 16 seconds to return to standby. I still noticed a faint odour of deodrant when I re-entered the room, but the purifier had made an obvious positive improvement to the air quality, surpassing the performance of many air purifiers I put through the same test.

I also tested the Blue Max 3250i in the kitchen to see how it coped with cooking fumes. My kitchen has a very old extractor fan that struggles to adequately remove cooking fumes, so I was interested to see how the air purifier would perform in comparison. 

To test out its powers I shut the kitchen door, made sure the windows were closed, left the extractor fan off and started frying two rashers of plant-based bacon whilst the Blue Max 3250i was positioned on the kitchen work surface in Auto mode a safe distance away.

From when the bacon first started sizzling, it took the Blue Max 3250i 3 minutes and 20 seconds to register the bacon smell at which point it soon shifted the fan speed up several gears as the fumes intensified.

Around a minute later the bacon had finished crisping up, so I snuck out of the kitchen, shut the door again, and set to work eating my bacon sandwich whilst the Blue Max set to work removing the bacon fumes. 

All in all, it took 11 minutes and 32 seconds for the 3250i to finish doing its thing, register the air quality as back to 'very good', and and return to its lowest fan speed setting.

At this point I re-entered the kitchen to see if my nose agreed with that 'very good' air quality rating, and I was super impressed. There was barely any lingering bacon smell lurking when I stepped back inside, and any trace smell remaining was certainly far less noticeable than it would have been had I been reliant on my not-very-efficient extractor hood or an open window during the frying process – impressive stuff.

Lastly, there was the dust test to perform. Whilst the AX91-604GY was in Auto mode I emptied the contents of my vacuum cleaner onto the floor next to it. The air quality indicator remained a constant blue for 'very good' air quality throughout this process.  That meant the purifier stayed on its lowest fan setting throughout rather than kicking the fan up a gear to clear the air – a bit of a surprise as I was expecting the dust particles to send the purifier into overdrive!

When I manually set the air purifier to its highest fan speed and performed the same exercise, I could clearly see the dust particles being drawn towards the air purifier, but again the indicator light didn't show a decrease in air quality.

Seeing as the Blue Max 3250i draws in air from 360°, it may be that the bulk of the air it was filtering was non-dusty and therefore overall the air quality remained high throughout the exercise. But, after it had performed so well in reacting to the smaller particulate in the air during the smoke and VOC tests I was a bit surprised it didn't register the larger particulate in the same way. However, on higher fan speeds the dust was visibily being drawn into the purifier, so it did still seem to be doing its thing!

However, overall I was incredibly impressed by the Blueair Blue Max 3250i Air Purifier's performance. Especially considering this is a relatively small air purifier in the grand scheme of things. 

The Blue Max 3250i has a CADR of 239 m³/h, which is on a par with the Levoit Core 300S air purifier, and far below the 620m3/h CADR of the much larger AEG AX91-604GY Connected Air Purifier I previously tested. However, in practice, I found the Blueair Blue Max 3250i more responsive to changes in air quality than either of these machines. 

Perhaps that's down to the 3250i's impressive filtration, with Blueair stating the Blue Max 3250i's HEPASilentTM dual filtration technology 'can remove airborne pollutants from the air faster and more quietly than traditional HEPA filtration alone'. That means the 3250i promises to filter out 99.97% of airborne particles down to 0.1 micron in size, whereas many air purifiers only promise to capture 99.97% of 0.3 micron air pollutants. Either way, in practice, the 3250i's performance is impressive.

Ease of use

The performance of the Blueair Blue Max 3250i Air Purifier really impressed me, but sadly I was slightly less impressed by the user experience of the Blue Max 3250i's on-board controls.

Although they're simple enough – there's just one button to turn the air purifier on and off, and another to toggle through its five settings – the buttons didn't feel that nice to interact with compared to other models. 

The fact you have to scroll through all five functions to get to the one that you want is also a little annoying. For example, if you're in Night mode and you want to switch the air purifier into Auto mode, you need to keep pushing the central button to scroll through fan speeds one, two, and three, before you can select Auto. Not a huge deal perhaps, but it certainly made me appreciate the more reponsive and user-friendly digital controls on models such as the Levoit Core 300S and AEG AX91-604GY Connected air purifiers.

Of course, you do also get the option of controlling the Blue Max 3250i via the Blueair App or through voice commands via Amazon Alexa or Google Assistant which cuts out the need to interact with the on-board controls at all. 

The App also gives additional air quality data that you can filter by day, week or month, and features a 'Welcome Home' function that means the Blue Max 3250i switches into standby when you leave the house and will turn back on when you're getting close to home. Handy, as this air purifier doesn't otherwise have a timer function.

Noise levels

The Blueair Blue Max 3250i Air Purifier is very quiet, measuring between 18-46dB dependent on the fan speed you choose. 

It only really gets loud when it's running in its highest fan speed, otherwise the low and middle fan speed are quiet, and the Night mode quieter still. 

Night mode also dims the lights on the air purifier making it a great option for use in the bedroom overnight.

Portability

As air purifiers go, the Blueair Blue Max 3250i is pretty light and fairly compact, weighing in at 3.39kg and measuring H48 x W27 x D27cm. 

That makes it easy enough to pick up and move around the home, although it does lack any hand holds, so you do need to have the ability to grip its cylindrical build with two hands. A built in carry handle would have been a nice touch.

And whilst its build isn't too sizeable, it was a bit too big to sit comfortably on most surfaces in my home, so you probably will need to place it on the floor. 

Energy use

Compared to most air purifiers of this size, the Blueair Blue Max 3250i is very energy efficient using just 2.5-20W of electricity depending on which mode you have it running in. 

It also features that super useful Auto mode that means you don't need to have the purifier constantly running on a high fan setting. Instead you can leave it in Auto and the air purifier will remain on its lowest setting unless it detects a drop in air quality, at which point it will swing into action at a higher gear – a great energy-saving measure. 

You can find out more about how much it costs to run an air purifier in our dedicated guide.

Filter replacement

The downside of pretty much every air purifier is that beyond the initial purchase price of the purifier itself, you also need to factor in the ongoing cost of replacing the air filter every so often. 

Generally manufacturers advise that an air filter should be replaced roughly every six months as it will gradually become clogged up with particulate and its efficiency therefore reduced. 

Blueair advises similarly, recommending the Blue Max 3250i air filter is replaced every 6-9 months. There's a red indicator light on top of the purifier that illuminates when this is necessary. You can also view more info on the health of the air filter within the Blueair App. 

The brand advises periodically cleaning the pre-filter – ingeniously this is the grey knit cover on the outside of the air purifier – using the soft brush attachment on a vacuum hose. The pre-filter can also easily be removed and washed for a deeper clean.

When you do come to replace the filter, replacement filters cost around £35 as of writing, so not too unreasonable compared to some purifiers.

Verdict

Overall, I was incredibly impressed by the Blueair Blue Max 3250i Air Purifier's performance. 

So far, the Blue Max 3250i is the most responsive air purifier I've tested. In our practical tests it almost immediately sensed changes in air quality and sprang into action to remove those impurities from the air. Its Auto mode is also a brilliant addition, meaning you can rely on the built-in air quality sensor to do all the hard work of managing your homes air quality .

That Automatic mode also means the air purifier is never using more electricity than it needs to, which saves on energy usage and reduces running costs. Plus, even when the when 3250i is operating on its highest fan speeds, with energy usage of between 2.5-20W, it's still a very energy efficient choice compared to much of its competition. And, replacement air filters won't break the bank like other options can. 

The air purifier's five-colour air quality indicator is another great feature, as is the fact the 3250i is Wi-Fi compatible and can be paired with the Blueair App if you want to make the most of the air purifier's Smart features, and connected to Amazon Alexa or Google Assistant if you prefer to use voice activated commands. 

And, the Blueair Blue Max 3250i Air Purifier is quiet and looks super stylish to boot. I also loved the washable pre-filter which felt like it was doing a much better job at protecting the HEPA filter from getting clogged up with particulate than the design of many comparable air purifiers.

That 3-Stage filter is another real plus point of the Blue Max 3250i. The filter is large, reasonably-priced when it comes to replacement, and of impressive quality compared to similarly priced air purifiers – able to filter out 99.97% of airborne particles down to 0.1 micron in size whereas many air purifiers only promise to capture 99.97% of 0.3 micron air pollutants.

In fact, the only real niggle I had with the Blue Max 3250i is that I didn't love its on-board controls. However, although a little clumsy, they were fine to operate, and there's the option of remote control operation via the Smart App or via a voice-activated device if you prefer, another real boon for many users.

Overall, I think the only reason not to invest in this air purifier, is if you want to filter the air in a room over the Blue Max 3250i's maximum 48m2 capacity, in which case I'd recommend the more powerful AEG AX91-604GY Connected Air Purifier that's designed for use in spaces up to 129m2. Or, in contrast, if your rooms are super small, then perhaps this mid-sized air purifier might be a tad too large, in which case the Levoit Core 300S air purifier tucks more easily into a tight corner or onto a work surface.

However, in terms of performance, usability and style, it's hard to fault this well-designed air purifier. The Blueair Blue Max 3250i Air Purifier is a brilliant all-rounder at a mid-range price point, and as long as your room sizes aren't larger than its 48m2 capacity, this is definitely the air purifier I would choose to invest in.

For my small kitchen, where I struggle to extract cooking fumes with the existing built-in extractor fan, it certainly improved the air quality considerably, and its relatively compact size means that if you're short on floor space you can pop it onto the countertop to do its thing. Plus, the Auto mode means you don't have to use more energy than you need to, just switch it on and it will kick into high gear when cooking fumes start to build up, and only continue to run until they're cleared. In fact, if only it could help with the washing up as well, it would be the perfect kitchen companion.

If you’re wondering whether an air purifier or a dehumidifier is better, you’ve come to the right place. As Ideal Home’s resident air quality, it’s literally my job to know the ins and outs of these appliances - including which homes (and which people inside of them) they suit best.

Yes, you probably don’t need me to tell you that both the best air purifiers and the best dehumidifiers are becoming increasingly popular. It seems as though more and more of us are concerned about the air we’re breathing and the overall health of our homes and family. But the reality is that air purifiers and dehumidifiers are very different appliances with very different uses.

That’s why you’ll find everything you need to know about the air purifier vs dehumidifier debate below. From their overall usefulness to their affordability, all of the information below will help you choose the right option for your home.

Air purifier vs dehumidifier 

Air purifier vs dehumidifier: What's the difference?

While you could say that air purifiers and dehumidifiers look alike, and they work in similar ways (after all, they suck in the surrounding air before releasing cleaner air back into the room), they still serve different purposes.

As Dr. Jaspreet Dhau, VP of R&D at Molekule explains, ‘Air purifiers are designed to reduce allergen particles in the air, such as dust mites, pet dander, pollen or mould spores.’ They can also remove other pollutants such as smoke and VOCs. They do this by capturing these harmful airborne particles in a filter and trapping them so they’re not released back into the air.

In fact, air purifiers with high-grade HEPA filters - like our top-rated model the Blueair Blue Max 3250i Air Purifier - can filter 99.97% of airborne particles down to just 0.1 microns in size - which is pretty impressive, as most air purifiers only promise to filter down to 0.3 microns. In most cases, these filters then need to be changed regularly to maintain maximum efficiency.

Dehumidifiers don’t trap airborne particles, though. Instead, they work hard to reduce the humidity of a room by removing excess moisture from the air. There are a lot of different dehumidifiers to choose from, too.

As Chris Michael, Managing Director at Meaco, says, 'There are four types of dehumidifier sold to the domestic market in the UK - Compressor, desiccant, peltier and absorbent salt-based (calcium chloride or silica gel).’

This can make choosing a dehumidifier daunting, but the most common type of dehumidifier sold in the UK is a compressor model. Chris says, 'A compressor-based dehumidifier draws the air in from the room over a filter and passes it over some cold coils similar to the coils on a fridge. As the coils are cold, water condenses and drips into a bucket. The air is then reheated to room temperature and blown back out of the dehumidifier.'

Just remember that when you buy a dehumidifier, you need to make sure you buy the right size for your home. Not only that, but you need to remember to empty the tank when it’s full.

Air purifiers vs dehumidifiers: Which is better for your health?

In the grand scheme of things, air purifiers and dehumidifiers are both impressive additions to your home. Because of this, it’s hard to say whether one is better than the other - especially when it comes to your health, as it’s very unique to everyone.

On the one hand, air purifiers can help hay fever and those who struggle with allergies as a result of airborne particles such as dust and pet dander. In many cases, air purifiers can also help those with weakened immune systems, as high-quality models also help to capture viruses and bacteria.

In fact, our Senior Digital Editor tested the Levoit Sprout Air Purifier in her young daughter’s room, who is susceptible to chest infections. After using it for just two weeks, she found that it significantly eased her daughter’s nighttime coughing and helped her breathe easier throughout the day.

And while a dehumidifier cannot get rid of mould per se, it can stop it from damp, condensation and mould getting worse or from appearing in the first place, so can still have a positive impact on someone’s health.

To be more specific, using a dehumidifier to remove excess moisture from the air is very beneficial for those with a weakened immune system or breathing difficulties, as the excess moisture and mould spores can wreak havoc on those with asthma or other respiratory conditions. That’s one of the reasons

Air purifiers vs dehumidifiers: Which is better for your home?

When it comes to the health of your home, there is a clear winner in the air purifier vs dehumidifier debate. After all, excess moisture can have disastrous consequences if not dealt with as soon as possible. It can even lead to structural damage in your home.

Whether you’re looking to tackle the excess moisture in your bathroom with a bathroom dehumidifier or you’re trying to stop damp in a bedroom, a dehumidifier can not only reduce this condensation and the opportunity for mould growth but can also work hard to maintain the humidity in your room.

Nicholas Auckland, energy expert at Trade Radiators, says, ‘A dehumidifier can be a real hero when it comes to banishing mould and condensation, and I always recommend purchasing one to anyone struggling with excessive condensation, mould and high humidity levels. Almost nothing else but making structural, expensive changes can completely fix this problem, so a dehumidifier is the perfect option if you're not in the right place to spend thousands.’

By using a dehumidifier, you can create an environment where you and your home can live together harmoniously without any mould breakouts or costly maintenance bills. You just need to make sure that you avoid these dehumidifier mistakes if you want to keep your home mould-free.

On the other hand, air purifiers benefit the people inside the home more than the home itself. Sure, an air purifier can remove mould particles from the air and even reduce the prevalence of dust and smoke stains, but ultimately, they just don’t trump dehumidifiers when it comes to maintaining the integrity of your house.

Air purifiers vs dehumidifiers: Which is more affordable?

When looking at the affordability factor of air purifiers and dehumidifiers, there are two things we need to take a closer look at; the price of the appliance itself and then the price of running said appliance.

Let’s start with air purifiers. The most affordable air purifier we’ve tested (and loved) so far is the £29 IKEA UPPÅTVIND Air Purifier. It’s very much basic in its form and function, and it’s fair to say that IKEA isn’t exactly known for being leaders in air quality. But if you’re looking for another cheap air purifier from a reputable air quality brand, the Blueair Blue Pure 511 Air Purifier will still only set you back £99.

At the other end of the spectrum, we have the most expensive air purifier on our list, which is the Dyson Purifier Big+Quiet Formaldehyde, which retails at £899.99. However, it’s important to note that the Dyson purifier is so much more than an air purifier. It’s designed for larger spaces and can also serve as a multifunctional fan at the same time.

But what about dehumidifiers? Well, they’re certainly a little cheaper. There are so many dehumidifiers under £100, and our firm favourite has to be the ProBreeze 1500ml Mini Dehumidifier (£54.99 at Amazon). it’s a budget way to keep your home mould-free - but it’s important to note that there’s a limit to that.

The ProBreeze is capable of reducing moisture in a 15m² area, so you might need to buy a couple if you want to tackle your whole house. Alternatively, you could opt for a budget dehumidifier that has a larger capacity, like the Dryzone Dehumidifier & Air Purifier, which retails at £149.99.

In terms of the top price for dehumidifiers, you could pay hundreds if you really wanted to. But in a normal house without any major moisture or mould issues, you shouldn’t need to buy something that pricey.

Air purifiers vs dehumidifiers: Which is cheaper to run?

While it’s clear to see that dehumidifiers are often cheaper to buy, it’s also important to note how much these different appliances cost to run.

Although you can read more about air purifiers on our cost to run an air purifier page, this ultimately depends on the current energy price cap and the wattage of the air purifier. At the time of writing, the current price cap (until 31st December 2025) is 26.35 pence per kWh.

The same can be said for how much it costs to run a dehumidifier. All you need to do is multiply the kWh of the appliance by 26.35 to work out how much it’ll cost you per hour.

Final verdict: Which one do you need?

The debate between these two appliances has been a tough one, as both air purifiers and dehumidifiers have their perks. They’re both very different but offer similar positive qualities that everyone should employ at home.

Only you will be able to choose a clear winner based on the needs of your own home. Joshua Warren, dehumidifier and air purifier expert at AO.com says: ‘The choice between an air purifier and a dehumidifier is a complex decision. With many struggling with the cost of heating their homes, households can use dehumidifiers to fight mould and mildew. They are terrific at absorbing the moisture left by damp conditions and help to protect your home from this recurring.’

‘Looking ahead to the warmer months, this is truly where an air purifier comes into its own – particularly for those suffering from allergies. If you’re perhaps a person who struggles with hay fever, look out for appliances with a HEPA filter as these models are specialised in improving air quality by removing allergens.’

If you can stretch to it, we would recommend investing in both appliances for a happy and healthy home. We’d suggest using both of these appliances throughout the year to maximise the benefits.
