Sale shopping advice
The demands of modern life mean that our homes are constantly being pumped full of moisture thanks to the regular cycle of bathing, cooking, washing and cleaning – all of which use gallons of hot water and can create steam. Let that steam and moisture build up and it will cause dampness, which can stain your walls, and, left unchecked, could cause long-term damage to your home, as well as your health.
If you struggle to properly ventilate your home by opening windows or using extractor fans in the kitchen and bathroom, or you're employing one of the best heated clothes airers to dry washing over winter, then a dehumidifier can be a useful ally in tackling excess damp and condensation.
A dehumidifier can be more economical than a tumble dryer when it comes to drying wet washing indoors. You just need to compare how much it costs to run a dehumidifier with how much it costs to run a tumble dryer to see the difference in electricity costs!
But what should you look out for before you shop an enticing dehumidifier deal?
Extraction rate: This tells you how much moisture a dehumidifier can suck from the air. It's generally measured in litres per hour, and is a useful way to compare dehumidifier performance levels.
Room size: Most dehumidifiers 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 dehumidifier 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 a dehumidifier that's powerful enough to cope with your space if you want it to eliminate moisture successfully.
Noise levels: Most dehumidifiers use a fan to suck air into the unit and pass it through a series of filters to extract the moisture before expelling the air back into the room. This means that dehumidifiers can be noisy, so if peace and quiet are important to you then you'll want to check out the dehumidifier's noise levels before you shop. These are measured in dB with dehumidifiers ranging from around 15dB on their lowest settings to 50dB on max.
When to shop for the lowest dehumidifier prices
Investing in air-quality appliances can be expensive, whether you're looking for the best air purifiers to help cut down allergens and indoor pollutants, one of the best fans or best portable air conditioners for keeping cool in the summer heat, or a dehumidifier to combat indoor moisture in the winter months.
Although you can get low cost dehumidifiers (you'll find our tried and tested favourites in our guide to the best dehumidifiers under £100), a cheap dehumidifier can lack power. That's why sale periods can be a great time to browse for top quality dehumidifier deals as they offer the opportunity to snap up a high performing dehumidifier for less.
October to January, when the weather gets cold and wet, are when dehumidifier sales peak, so if you can time your purchase 'out of season' during the summer months then you're more likely to find the cheapest dehumidifier prices. Key discounting events, like Amazon Prime Day and Black Friday, are also a great time to look for reduced dehumidifiers.
Black Friday and Cyber Monday dehumidifier 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.
Black Friday always falls on the last Friday in November, so the next time it will roll around is November 29th 2024.
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 dehumidifier deals and Cyber Monday dehumidifier deals. Last year, Black Friday dehumidifier 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 dehumidifier deals and Cyber Monday dehumidifier deals as they drop.

Amazon Prime Day dehumidifier deals
Amazon Prime Day – the brand's yearly price-slashing event – can mean some great Prime Day dehumidifier deals.
In 2023, Prime Day dehumidifier deals ran from the 11th-12th of July and the 10th-11th of October, with significant discounts on both the ProBreeze Amazon storefront and Russell Hobbs Amazon storefront.
Prime Day dates for 2024 are yet to be confirmed by Amazon, but, after two Prime Day deals events in 2023, it seems likely we can expect another double whammy. Keep an eye on our Amazon Prime Day deals page for all the latest news and best deals as they launch.
In the meantime, you could sign up for Amazon Prime membership so you're all set to shop when the next Prime Day dehumidifier 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.
We'll do our best to keep this page updated with the best dehumidifier deals around, so remember to check back – especially during the key sale dates we've listed above.
