Autumn is officially here, and while we’re looking forward to cosy nights in and cute knitwear, the season certainly comes with its downsides – with tackling condensation, damp and mould among them. To keep your home a sanctuary throughout the colder months, you may want to make removing excess moisture from the air a priority, which is why we’ve pulled together the best dehumidifier deals to help you do just that.
Damp and mould can lead to a range of health problems, so it’s important to address such issues quickly. Unavoidable tasks such as cooking, showering and drying clothes can all contribute to the problem, but airing out your home by opening windows and doors can make a big difference, as can investing in one of the best dehumidifiers, reviewed by experts.
Dehumidifiers can also help you dry your laundry without needing to run the tumble dryer, which can help you cut down your energy bill during the colder months. Not to mention that humid rooms can be uncomfortable, and these appliances help to tackle that.

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 that way. When this material is heated up, the moisture then drips into the water tank.
