16 best dehumidifiers to get rid of damp and mould in your home
Our experts put them through their paces in the lab

The best dehumidifiers help eliminate excess moisture and condensation from the air, so your home doesn't fall victim to damp or spots of mould.
A dehumidifier can also help dry laundry faster – essential when you're tackling rainy, changeable weather, which can make drying clothes a lot more difficult (and lead to annoying musty smells). They’re cheaper to run than the tumble dryer., too
To help you decide which one to invest in, the Good Housekeeping Institute tested a range of market-leading models, keeping an eye on how much they cost to run and any useful extra features, including laundry modes.
Best dehumidifiers to buy in 2025
We review dehumidifiers by placing them in a controlled test chamber with the humidity set at 80% and the temperature at 18C. We then run each model on its highest setting to see how much water it collects in two hours. You'll find a full breakdown of how we test below our reviews.
Compressor or desiccant dehumidifiers – which is better?
There are two different types of dehumidifier to choose from: compressor or desiccant models.
Compressor dehumidifiers work by creating a cold surface for warm, damp air to move across. When the warmer air meets the cool surface, condensation forms, and the water is removed.
Desiccant dehumidifiers don’t rely on a cool surface, which means they’re effective in all temperatures. They use a desiccant wheel that absorbs the moisture from the air (much like a sponge), which is then regenerated by an internal heater and fan.
The simplest way to work out which type of dehumidifier is best for you is to consider room temperature. For situations where your ambient room temperature is likely to fall below 15 degrees often (think garages, basements, conservatories), you may want to consider a desiccant dehumidifier.
While desiccant dehumidifiers are more effective in lower temperatures, they typically cost more to run, so if you’re looking for a more energy-efficient appliance, it may be worth picking a compressor model.
Now you know which type you want, these are our best in test.
