Best dehumidifier deals in November 2025 – save on tried-and-tested models
Find discounts on dehumidifiers that stood out when we reviewed them
It’s November, and ’tis the season for thermostat wars. With the current cost of energy, many of us fall on the side of putting on extra layers instead of turning on the central heating. But while this can save money, it can also cause problems with damp, mould and condensation, particularly if you’re drying clothes inside. “Just open the window,” your landlord will say as if it isn’t five degrees outside. Fortunately, there’s a better way.
Investing in a dehumidifier can help you prevent these common household problems, while helping you dry your laundry without the cost of running a tumble dryer. IndyBest reviewer Joanne Lewsley, tried a range of dehumidifiers in her own home, testing the effectiveness, noise levels and running cost of each one.
Of course, with Black Friday coming up, it may be a good idea to hold off buying a dehumidifier, to see if you could get a better deal than the ones below. But it’s important to address issues of damp and mould quickly, so if the situation calls for it, here are the best dehumidifier deals you can take advantage of right now.

The best dehumidifier deals for November 2025
Duux bora smart dehumidifier
IndyBest tester Joanne Lewsley praised this model in her review, saying: “This dehumidifier can extract up to 20l of water in a 24-hour period, making it ideal for homes with severe humidity issues. Its generous 4l tank means less frequent emptying and an auto-shut-off feature prevents overflow.” Right now, you can save £50 on the top-rated model.
Zanussi 18l dehumidifier, ZDH1802
“The dedicated laundry mode impressed us, significantly speeding up drying time for a full clothes horse of washing,” said IndyBest tester Rachael Penn when reviewing this dehumidifier. Recommending it for small to medium-sized spaces, she found that it “works quickly to remove excess moisture”. The auto defrost and restart function “enables use in colder areas such as outhouses, conservatories, and garages during winter months, too”, she said.
With this deal, you can currently save £30 on the price at Currys and Amazon.
Daewoo 2l portable dehumidifier
If you want a dehumidifier you can easily move around the house, check out this one from Daewoo. Helpfully, it comes with an auto-shut-off feature, meaning that when the tank reaches maximum capacity, a light will flash and the appliance will switch off until the tank has been emptied. With this deal, you can save a modest £10 on the price of the 2l model.
Honeywell TP-FIT 12l dehumidifier
If you’re limited with your available floor space or would just rather your dehumidifier not be a feature in your home, this model from Honeywell is an excellent pick. “This dehumidifier proves that good things do come in small packages. The compact unit packs a surprising punch, collecting up to 12l of water over 24 hours, with a generously sized 2.5l tank,” noted our reviewer.
Blyss WDH-316DB 16l dehumidifier
This dehumidifier is currently just shy of £130 at Screwfix. Looking at the ‘was’ price, it may not seem like a steal, but we’ve seen it listed for £179 in the past, so we think this is a decent offer. Our tester, Joanne Lewsley, praised the model for being efficient and easy to set up. “I liked the swing function, which automatically moves the air outlet grille to spread dry air more evenly – it is especially handy when trying to dry a room as a whole,” she said.
How does a dehumidifier work?
Dehumidifiers are all about ousting excess moisture from the air in your home, which should ease the effects of damp, whether that be mould accumulating on the walls or tackling dust mites (which thrive in warm, damp conditions).
There are two kinds of dehumidifiers you can choose from, depending on the conditions in your home. The first of these is referred to as a refrigerator dehumidifier, as it works by drawing moisture in through a fan before cooling it with very cold, refrigerated coils. Cooling the air creates condensation, which collects in the dehumidifier’s tank (this is why transparent tanks can be helpful). These are generally best if your house tends to be warm.
The second relies on some kind of absorbent material, which will suck up any damp from the air. When this material is heated up, the moisture then drips into the water tank.
