Best dehumidifier deals in March 2025 to banish the damp
Tackle damp and pollutants in your home with these top-rated, discounted models
As winter lingers and Spring showers appear on the horizon, damp in our homes is a great concern. Thankfully, there are plenty of dehumidifiers designed to help you combat condensation and prevent mould but the handy appliances don’t come cheap. Fear not, though, as, true to form, we’ve tracked down the best dehumidifier deals around.
If you’re wondering how these household appliances work, dehumidifiers remove excess water in the air and lower humidity levels, which, in turn, gets rid of allergens, mould, damp and pollutants. Not only do they offer an economical way to dry your laundry – as they draw moisture from fabrics – but they are also cost-efficient (the average cost of running a dehumidifier is less than 40p an hour).
Whether you’re looking to have one in a large or small room, there are plenty of options on offer, with mini and extra-large machines available. We’ve spotted some serious savings on models from big-name brands, including Sharp, Black+Decker and more. There are some huge savings to be had on large 20l capacity models, as well as compact options.
Helping you in your dehumidifier-buying quest, the IndyBest team is here to point you in the direction of the hottest deals available now.

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 actually 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.
