Best Rated Dehumidifiers

Built for British homes: Our best rated dehumidifiers

If you’re on the hunt for a dehumidifier that’s already been tried, tested and loved, you’re in the right place. Our best-rated dehumidifiers are powerful, genuinely energy-efficient and fully equipped to tackle the everyday moisture issues. Whether it’s for drying the endless pile of washing, battling condensation running down the windows or stopping damp and mould in its tracks, these models have earned their stripes.

Low running costs, high performance

With energy prices still a major concern, the first thing most customers want to know is: how much does it cost to run? Many of our top-rated models cost as little as 4p an hour to run on a typical UK energy tariff. If you’re using your dehumidifier for about 8 hours a day across a typical 6-month damp season, that’s still under £60 a year for peace of mind, comfort and mould prevention.

Check the wattage on each model (usually between 150 and 350W). Compressor units are the cheaper-to-run choice for warm, heated homes (above 15°C). Meanwhile, desiccant models are ideal for cold spots like garages, conservatories, or cellars, as they work efficiently even at low temperatures.

How much moisture can it actually remove?

Our highest rated dehumidifiers include clear extraction rates, ranging from 10L/day for flats or small rooms to 25L/day or more for larger homes or serious damp problems. That tells you how much water it can pull from the air in a day. The bigger the space, or the worse the damp, the higher the number you’ll want.

To help you choose easily:

• 10–12L models are ideal for single rooms, box rooms, or flats.
• 16–20L models work well for 2–3 bedroom homes.
• 25L+ units are suited to 4+ bedroom houses or very damp basements.

You’ll also want to check the recommended room size listed in square metres or number of bedrooms. It’s an easy way to match the model to your home.

Less effort, more drying power

Most of our best-sellers are equipped with a dedicated laundry mode. This boosts performance and helps dry a rack of washing indoors in around 4 hours. A brilliant, cheaper alternative to the tumble dryer.

The setting increases airflow while keeping the humidity in check. It creates a quick-drying environment that also prevents the usual condensation and mould on your windows. That’s a game-changer in colder months or if you don’t have access to outdoor drying.

Fit for everyday life

UK homes are often short on space and big on damp zones, so convenience matters. The most highly rated dehumidifiers here tend to include features that just make life easier:

• Large water tanks (4–6L) for fewer trips to empty
• Continuous drainage option, great for utility rooms or basements
• Sleep Mode or quiet operation. Many run at 35–40dB, which is low enough for a bedroom
• Auto shut-off when the tank is full or target humidity is reached
• Castors or carry handles for moving between rooms

Added air quality benefits

Several of our best rated dehumidifiers also help clean the air. Models with built-in air purification or a HEPA filter (look for H13) are ideal for allergy sufferers, pet owners or families with small children.

These trap pollen, dust mites, pet dander and even mould spores as they pull moisture from the air. Some also include an activated carbon filter, which helps neutralise musty smells or VOCs from household cleaners. These are very helpful in older or poorly ventilated properties.

Our best sellers are best for a reason

These models didn’t get rave reviews by chance. Each one has been thoroughly vetted by UK customers who’ve used them in real homes. So if you’re after something reliable, simple to use and cheap to run, you’ll find the perfect match right here.
