The best dehumidifiers 2021
If you have damp, mould or condensation issues and live in a larger property, you will need a stealthy dehumidifier to target those humidity levels. The Meaco Platinum Dehumidifier does just that and is designed for houses with three to five bedrooms. It also has a massive 5L tank.
Despite its size, the Meaco 25L Low Energy Dehumidifier is one of the cheaper models on the market to run, using just 270W, making it cost-effective. You could be saving up to £100 compared with other machines!
Again, despite its size, the Meaco is relatively quiet. Many reviewers call this an unexpected bonus, and the castors and carry handle means it’s easy to move around the house. The digital display makes it very straightforward to use, too.

Want peace of mind and a damp-free home? Then, the EcoAir DD122FW is the best desiccant dehumidifier for you.
The dehumidifier has an extraction rate of 7L and a tank capacity of 2L, and there’s an indicator to tell you when the water tank is full. The auto shut-off feature will avoid overflowing, and the silver filter kills bacteria on contact. On top of all that, when on low fan mode, it runs super quietly at around 34dB.
With a power consumption of 390-640W, this dehumidifier is the best pick for those who are eco-conscious. In addition, there’s the option of continuous drainage with the 1m house (supplied), plus a built-in heater.

Suitable for homes with up to three bedrooms, the electriQ 20L Low Energy Dehumidifier is up to 40 per cent cheaper to run than a standard dehumidifier. It’s also straightforward to operate and is quiet.
This handsome dehumidifier has four main modes: Smart, where it regulates itself to give your home an optimal humidity level; Low, for overall moisture reduction; High, for laundry drying; and an Air Purifier Mode where it doesn’t suck in any moisture, just drawing impurities from the air.
UV sterilisation is built into the dehumidifier, getting rid of pollen, smoke, dust and allergens. It also kills bacteria. We’re not making any extraordinary claims about its ability to disinfect your home but, when we used it, we experienced an immediately purer-smelling, fresher air quality, so it must be doing something.
On the front of the machine, there’s a coloured ring that will light up green when the humidity in your home is just right, orange when it’s higher than recommended levels and red if it’s too high. So you know when to use the machine - or not. It will also stop functioning once it’s reached the desired humidity level, so you won’t even need to remember to switch it off.
The 4L tank is antibacterial, so you needn’t worry about mould growing in there. Once it’s full, the machine will turn off to stop it from overflowing.

A teeny tiny dehumidifier with enough power to remove moisture from a small room or area, the Duronic DH05 Mini Dehumidifier is for those with the occasional need rather than more frequent humidifier battlers. The machine is suitable for rooms up to 15m2 so that it could be ideal in a utility room or other small space.
The Duronic Mini has an automatic off switch that activates as soon as the tank is full. This is convenient as you can turn it on and leave it without checking on its progress. If you come back to a sleeping dehumidifier, then empty the tank and start again! No wasted electricity.
Though the small dehumidifier certainly can’t claim the same moisture extraction and capacity levels as others on this list, the budget price tag is a suitable trade-off. The design of the machine also allows you to monitor how much water is in the tank at any one time so that you won’t be caught off guard.

With a decent extraction rate, laundry mode and easy movement, the 10L De'Longhi Tasciugo AriaDry dehumidifier is ideal for space like the bedroom, where you might not want the appliance to stay full-time.
The De'Longhi offering has a handle on top to make it easier to move from room to room (or from room to storage), and, despite its size, it's surprisingly lightweight at just 1.5kg. This makes it easy to put it wherever you want, at any time of year. It's also relatively quiet, operating at 37dB. This certainly isn't 'whisper-quiet', but it is on the lower end of the scale for dehumidifiers.

With all of us becoming more conscious of the air quality around us every day, a dehumidifier that promises to remove allergens and other particles while it works is a bonus. The Argo 2650E Smart dehumidifier does just that, with a built-in Air Purification Mode designed for the British climate.
It's noisier than some and has a slightly higher price tag, but for the extra cash, you'll get an above-average extraction rate and a 3.5L water tank, which means you won't have to think about emptying quite so often. The Argo machine also has a convenient built-in sensor that allows it to turn on and off depending on the humidity levels in the room.
The efficient Essentials C10DH19 Dehumidifier is excellent for those who want a quick, cheap fix to the damp problem in their home. While it doesn't have the added functions of laundry mode or an air purifier, at this low price, you can't complain. We think it's a great budget dehumidifier and one of the best dehumidifiers you can buy.
Despite being a budget buy, it has a decent extraction rate. It's also easy to move from room to room thanks to its carry handle.
It's also worth noting that it has auto shut-off, so the machine will stop to avoid it overflowing when the tank's full. In addition, the filter can be removed and washed for easy maintenance.
How to choose the best dehumidifier for your home
Why do I need a dehumidifier?
Poor ventilation is the main reason for purchasing a dehumidifier. The majority of households regularly shower or bath, cool and wash clothes, all of which use a lot of hot water that creates steam. If there’s no way for the moisture to escape through windows or vents, then condensation and dampness begin to build. This is where a dehumidifier helps prevent this from happening and removes excess moisture from the air to help dry your clothes.
How does a dehumidifier work?
The way that dehumidifiers remove unwanted moisture from the air varies. For compressor models, the air is taken in through a filter and coils inside. The cold temperature of these coils converts the moist air into water, which is then deposited into the tank. Desiccant dehumidifiers, meanwhile, take in the moisture via an absorbent, which the machine then heats to convert into water.
Do dehumidifiers cool rooms?
Dehumidifiers do not work the same as air conditioners, which often also operate as a dehumidifier. Confused?
As stated above, compressor dehumidifiers use their interior components' temperature to operate, so it's actually beneficial for them to be put to work in warmer spaces. This means that there is more contrast between the temperature of the air and the colder temperature of the coils that the dehumidifier uses to convert moisture into water.
What type of dehumidifier should I get?
Not to be confused with a humidifier, which does the opposite of a dehumidifier and adds moisture to the air in your home, you can buy two different types of dehumidifier—first, a compressor (sometimes known as a refrigerant) or second, a desiccant. Compressors can remove a more significant amount of moisture per day and are cheaper to run, which desiccant dehumidifiers work better in colder temperatures and are often quieter. They’re also usually smaller and lighter than compressor models.
What extraction rate and tank size should I go for?
The extraction rate you’re looking for really depends on where you live and what you’re using the dehumidifier for, but in the UK, you can aim for one that extracts between 1-2.5L a day.
The tank size of the products on our list range from 1.8-4L, and the size you need will depend on a) whether your dehumidifier will be turned on all day, b) whether you’re at home and can empty it periodically, c) what level of humidity you’re dealing with, and d) how much space you have.
Do I need a laundry mode?
If you often hang your clothes to dry around your home, opt for a dehumidifier with a dedicated laundry mode. It’ll work with the additional humidity caused by your wet clothes as well as reducing the time it takes for your clothes to dry. Win-win?
