Dehumidifiers & Air Purifiers
Ever spotted condensation on your windows or noticed a musty smell that just won't shift? That's excess moisture at work, and if left unchecked, it can lead to damp, mould, and lingering odours. That's where a dehumidifier steps in. It draws out that unwanted moisture, keeping your home feeling — and smelling — fresh. And if allergens are the problem, an air purifier works hard to filter out dust, pollen, and pet hair. Need the best dehumidifier to remove mould in your bedroom or an air purifier to keep sniffles at bay? Or maybe you're after a small dehumidifier or moisture trap that won't take up too much space? Whatever you're looking for, we've got plenty of tried-and-trusted options — all backed by our 3-year guarantee.
Frequently asked questions
What does a dehumidifier do?
In short, a dehumidifier keeps your home free from excess moisture. They work by drawing in humid air, cooling it to condense the moisture into water droplets, then collecting that water in a tank or draining it away. The drier air is then released back into the room, helping to prevent damp, condensation, and the mould that can come with it. It even helps laundry dry faster by pulling excess damp from the air so clothes don’t end up smelling musty.
High humidity can also trap airborne pollutants like dust and pollen, so by lowering moisture levels, dehumidifiers create a cleaner, healthier space that’s easier to breathe in. Perfect for keeping that fresh spring-clean feel going all year round!
What does an air purifier do?
Ever wondered what’s floating around in the air at home? Air purifiers help get rid of all those bits — dust, pollen, pet hair, and even bacteria — by pulling in air, trapping unwanted particles in a filter, and releasing cleaner air back into the room.
Many air purifiers also use activated carbon filters that trap odours rather than just masking them. Whether it’s pet smells, cooking fumes, or musty air, they help to keep your home smelling fresh.
Dehumidifiers and air purifiers are more popular than ever, with our Home and Cleaning Trends Report showing a 29% rise in sales in 2024 compared to the previous year. It’s clear that more people are turning to them to freshen the air at home — proof of just how much of a difference they can make to everyday life!
What size dehumidifier do I need?
The best size dehumidifier depends on the space and how much moisture you’re dealing with. A compact dehumidifier is a great choice for bedrooms, home offices, or smaller rooms, while larger models work best in open-plan spaces or particularly damp areas like utility rooms. Not sure what you need? A hygrometer can help you measure humidity levels so you can pick the perfect fit.
For smaller, enclosed spaces like wardrobes or bathrooms, a moisture absorber — also known as a moisture trap — might do the trick. Unlike dehumidifiers, they don’t need power; they use moisture-absorbing crystals to quietly soak up excess dampness.
How much does a dehumidifier cost to run?
Not as much as you might think! Most modern dehumidifiers are designed to be energy-efficient. But generally, the bigger the model (and the higher the wattage), the more energy it'll use.
Larger dehumidifiers can use up to 500 watts, while smaller, more compact dehumidifiers tend to run on much less — some as little as 22 watts.
If you're on a budget, moisture traps are a great option, as they don't use any electricity at all. Instead, they rely on moisture-absorbing crystals to soak up damp air, so there are no running costs to think about.
