Improving indoor air quality doesn't come cheap, which is why air purifier deals are always a welcome sight. 

Air purifiers work by filtering contaminants such as pollen, smoke, and dust from the air, helping to improve indoor air quality in your home, and potentially lessening the effects of conditions such as hay fever, asthma, and pet allergies. However, prices for a good air purifier tend to start around the £100 mark and can quickly increase to over £500, so shopping whilst there are air purifier deals on the table can mean a significant saving on RRP.

As such, we've rounded up all of the top air purifier deals available right now. We've prioritised deals on the best air purifiers the Ideal Home team has tried and tested, scouring the shops for the lowest prices on bestselling air purifiers from Blueair, Levoit, Philips, AEG, Dyson, and more. 

If there aren't currently deals on our favourites, we'll bring you the next best thing, sourcing affordable air purifiers that are in stock and offer great savings.

Sale shopping advice

If you haven’t used an air purifier before, it can be a great way of cleaning indoor air to remove pollutants, allergens, and bad odours. ‘There’s mounting evidence that indoor pollution can pose more of a health threat than outdoor pollutants,’ says biochemist and medical herbalist Dr Chris Etheridge. ‘Improving indoor air quality is key to tackling conditions like asthma and chronic obstructive pulmonary disease (COPD).’

An air purifier usually works by sucking in air and purifying it through water and/or filters before releasing cleaner, fresher air. Some say that using an air purifier can be as powerful as having hundreds, if not thousands, of houseplants around the house. And it won't need nearly as much looking after!

However, before you get bowled over by all the great air purifier deals available this month, there are a few pieces of terminology worth understanding before you shop to help you find the right product for you.

CADR: 'Clean Air Delivery Rate (CADR) is a measure of an air purifier's efficiency in cleaning the air' says Lars Dunberger, Technology Development Manager at Swedish air purifier manufacturer Blueair. CADR measures an air purifier’s effectiveness based on the volume of air that the appliance can filter in a given time, this is usually communicated in m³/hour, or, confusingly, m³/minute. This is often separated into readings for how well the product can filter the three main indoor pollutants; dust, pollen, and smoke.

Room size: Most air purifiers will tell you the maximum area they can successfully filter in the specifications. This tends to be measured in m³ which takes into account the room's length, width, and height. The larger the space the air purifier can filter, the more expensive it's likely to be, and more powerful appliances are also likely to be heavier and bulkier. However, it's important to invest in an air purifier that's powerful enough to cope with your space. A small bedroom will be easily filtered by a smaller air purifier, whilst an open-plan space is likely to need a more powerful unit.

Noise levels: Most air purifiers use a fan to suck air into the unit and pass it through a series of filters to clean it. Just like the best fans on the market, this means air purifiers can be noisy, and if peace and quiet are important to you then you'll want to check out the air purifier's noise levels before you shop. These are measured in dB with air purifiers ranging from around 15dB on their lowest settings to 50dB on max.

When to shop

Investing in air-quality appliances can be expensive, whether you're looking for one of the best fans, or best portable air conditioners for keeping cool in the summer heat, or the best dehumidifier to combat indoor moisture in the winter months.

That's why sales periods can be a great time to browse for air purifier deals as they offer the opportunity to snap up a bargain on one of these popular appliances.

As there are no particular 'off seasons' for air purifiers it's hard to predict when discounts might fall. Although July, August, and September – when more of us in the UK are outside enjoying the summer weather – can prove a quieter time for indoor air quality sales which, in turn, can result in retailers discounting air quality products. 

Beyond that key sales dates like Amazon Prime Day and Black Friday are a great time to shop for these popular appliances for less.

If you have your eye on a particular product then the best way to stay in the loop regarding sales is to sign up for the brand's email newsletter, this way you're likely to be the first to hear about air purifier sales when prices drop – or you could bookmark this air purifier deals page, of course!

Amazon Prime Day air purifier deals

Amazon Prime Day – the brand's yearly price-slashing event – can mean some great Prime Day air purifier deals. 

This year, Prime Day air purifier deals ran from the 11th to the 12th of July, with significant discounts at both the Blueair Amazon storefront, the Levoit Amazon retail page, and the AEG Amazon store.

Usually, Prime Day air purifier deals are a once-a-year event, although in 2022 Amazon did launch a second price-slashing event in October. Keep an eye on our Amazon Prime Day deals to be the first to hear if details of a second event are unveiled this year.

In the meantime, you could sign up for Amazon Prime membership so you're all set to shop when the next Prime Day air purifier deals take place. Generally, you need to be a Prime member to take advantage of the biggest discounts on Prime Day. You can sign up or renew your membership below. Usually, new Prime members can also access a free 30-day membership trial to test out its perks.

Black Friday air purifier deals

The term 'Black Friday' originated in the US to denote the first day following Thanksgiving when retailers would cut prices to draw holidaymakers to shop their store's sales. Driven by global brands, the price-slashing event soon crossed the pond, and now Black Friday – closely followed by Cyber Monday – has become one of the UK's biggest consumer extravaganzas, rivaling traditional Boxing Day sales. 

Often hailed as the biggest shopping day of the year, Black Friday always falls on the last Friday of November, so the next time it will roll around is Friday 24th November 2023.

That said, in recent years, the event has spread to encompass more than just one day, with retailers starting Black Friday discounting earlier and earlier so that a full Black Friday 'week' of discounts isn't uncommon. Last year, we even saw retailers running Black Friday promotions throughout the whole month of November.

Whether or not you agree with the rampant consumerism Black Friday has now come to represent, there's no denying it can be a great time for Black Friday air purifier deals and Cyber Monday air purifier deals. Last year, Black Friday air purifier deals were fairly thin on the ground, but previous years saw some hefty discounting, so we'll be keeping our eye out for all this year's top Black Friday air purifier deals and Cyber Monday air purifier deals as they drop.
