Dreaded black spots on your walls and pools of water around your windows are telltale signs that your house has damp issues. Thankfully, a dehumidifier can reduce humidity before it causes any lasting damage to you or your home.
Thanks to the UK’s cold winters, our homes become warmer on the inside than the outside making them very humid, so it’s not uncommon to find mould, damp or condensation on your walls and windows. A dehumidifier can help to dry out your home by removing excess water from the air. But don’t get it confused with a humidifier, which adds moisture into dry environments.
Dehumidifiers can be purchased in various sizes to suit different homes, damp issues and budgets. To help you find the right one for you, we’ve researched the best products currently on the market and consulted Mumsnetters for their top recommendations.
Here are the 10 best dehumidifiers to help keep your home damp-free this year.
1. Best overall dehumidifier: Pro Breeze 1500ml Dehumidifier
Price: £59.99 | Buy now from Amazon
“Pro Breeze is the one for you. We used to have really bad condensation in our dining room and we brought one of these. It's really helped us out.”
If you don’t want a big, noisy device taking up space in your home, the Pro Breeze Dehumidifier is so compact and quiet that you’ll barely notice it’s there.
With an extraction rate of up to 500ml a day, it won’t eliminate a serious damp problem or be effective in larger rooms, but it will remove moisture from a small room to manage the build-up of mould.
The Pro Breeze can hold up to 1.5 litres of water so you won’t need to empty it too often. It comes with an auto setting, which turns off when it’s full, and an LED light lets you know it needs emptying. It’s very lightweight so can be easily moved from room to room.
This device uses Peltier technology which means that it’s not as powerful as other models, but it’s low energy and quiet (around 40dB – the same as a refrigerator) so you can use it in your bedroom or office.
- Large tank capacity
- Very quiet and compact
- Not suitable for large rooms
- Isn’t as powerful as other designs
- Extraction rate: 500ml
- Capacity: 1.5L
- Power: 40w
2. Best budget dehumidifier: Duronic DH05 Mini Dehumidifier
Price: £34.99 | Buy now from Amazon
Tackling damp can be costly, but the Duronic DH05 Mini Dehumidifier can remove excess moisture in your home without making a huge dent in your bank balance.
It’s really affordable, but it’s also one of the smallest dehumidifiers around so it won’t work for a whole house or large spaces. Removing up to 250ml a day and with a 500ml tank, it works well in small, targeted areas of damp such as box rooms, a windowless bathroom or a cupboard, although you will need to empty it regularly.
The Duronic DH05 looks nice too, with a sleek black finish – a nice change from the standard white. Being so compact, it can fit on a shelf or cupboard and is easily portable. A Peltier device, it’s really quiet too (around 35dB).
It’s very simple to use with a one-touch switch and an LED light that lets you know when it’s full. A clear window on the tank also allows you to keep an eye on the levels. The Duronic DHO5 is low energy too, so you won’t run up a huge electricity bill.
- Nice sleek, black design
- Low energy so cheap to run
- Not effective in large areas
- Basic settings
- Extraction rate: 250ml
- Capacity: 500ml
- Power: 22.5w

3. Best dehumidifier for your bedroom: XNFEEL Dehumidifier
Price: £33.99 | Buy now from Amazon
Thanks to its compact design and colourful LED lights, the XNFEEL 1000ml Dehumidifier will blend nicely into your home. A mini dehumidifier with the ability to extract up to 450ml a day, this dehumidifier will work effectively in a small room, such as a steamy kitchen, bathroom or a bedroom, to prevent condensation and mould.
This Peltier device doesn’t have a noisy compressor so it won’t keep you awake at night and the LED light has a good choice of six colours. It can be easily adjusted using one-touch controls and can hold up to one litre, with a red light to let you know when it’s full. There’s also a handy clear water tank so you can keep an eye on the water level.
This dehumidifier is fairly low energy, and is really small and lightweight. At the lower end of the price range, it’s a great option for a bedroom or smaller space.
- Quiet enough for a bedroom
- Colourful LED lights
- Needs to be placed at least 0.5m from the wall for best functioning
- Not great for large spaces
- Extraction rate: 450ml
- Capacity: 1L
- Power: 40w
4. Best Dehumidifier with HEPA Filter: Meaco 20L LE Low Energy Dehumidifier
Price: £227.97 | Buy now from Amazon
“I have a Meaco 20-litre one which is a whole house dehumidifier (about a three-bedroom size – you might need two if bigger) and it's fab.”
“Meaco 20L Low Energy – it's expensive but worth it. We're in a three bed 30s semi which was permanently damp and, since having this, it's been an astonishing difference. It's quite quiet, I don't notice the sound and I like that it purifies the air too.”
While all dehumidifiers will reduce moisture in the air to prevent dust mites, mould and mildew, the Meaco 20L Low Energy Dehumidifier comes with a HEPA filter to clean and remove allergens from the air.
With an extraction rate of 20 litres and a water tank that can hold up to six, you won’t need to empty it too often and you can attach a hose (which you need to buy separately).
This is a powerful device that has two fan speeds and a built-in humidistat to monitor both warm and cold rooms. This makes it very energy efficient as the device maintains the chosen humidity rather than running continuously.
The Meaco 20L is bulky and heavy, but there’s a handle and wheels to make it easier to transport. It comes with a 24-hour timer, a louvre for directing air flow and a child lock. Part of the Meaco Platinum range, this dehumidifier is pricey but it can tackle damp issues – whilst also cleaning the air – in medium to large homes, so you shouldn’t need to fork out for more than one device.
- HEPA filter to clean the air
- Large capacity and water tank
- Bulky and heavy
- Hefty price tag
- Extraction rate: 20L
- Capacity: 6L
- Power: 219W
5. Best dehumidifier for drying clothes: EcoAir DD1 Simple Dehumidifier
Price: From £164.94| Buy now from Amazon
“It blows out warm air and, if we shut the door where the washing is, it gets quite toasty. It turns itself off if the water container gets full. We don't have huge damp problems – it's an older property though so it’s a little damp, but feels better since we started using the EcoAir.”
“I have an EcoAir and wouldn’t be without it. Dries winter washing so well. Used to dry clothes on our radiator and had mould and musty smells but no more.”
A desiccant dehumidifier, the EcoAir DD1 Simple 7L can effectively control mould, bacteria growth and condensation both inside your home and in unheated spaces such as a garage or basement. While it can extract up to seven litres in a day, it’s slimline and lightweight (6kg) and comes with a handle for moving it around.
While it can only hold up to two litres of water, it does come with a hose so you can continuously drain the tank. This device is easy to use, with a choice of economy or turbo mode for times when you want to dry an area quickly, and a laundry setting to help dry clothes more quickly indoors. There’s also a humidistat for maintaining the appropriate humidity levels in a room.
As with most desiccants, it does use more energy, but it’s also more effective over shorter periods. The DD1 Simple is quiet too, at just 36db (34dB when in economy setting), so you can work or sleep nearby without being disturbed.
- Laundry setting for drying clothes quicker
- Works in both cold and warm spaces
- The tank needs to be carefully handled to prevent leakage
- Uses more energy than other dehumidifiers
- Extraction rate: 6L
- Capacity: 2L
6. Best dehumidifier for large spaces: MeacoDry Arete® One 25L Dual Dehumidifier & HEPA Air Purifier
Price: £326 | Buy now from Amazon
If you know you're going to use your dehumidifier a lot, then it might be worth investing in a hardwearing piece of kit like the MeacoDry Arete One. Designed with a 25l capacity, it's ideal for larger homes and drying laundry.
It's much quieter than most dehumidifiers, and we like it comes with a HEPA air filter as standard.
Whilst the Arete isn't small, it's a little less of an eye-sore than other dehumidifiers on the market. The minimalist control panel is intuitive, and the base unit has wheels to make it easier to move around.
At £326, it's a big initial investment, but for larger houses or prolonged use, we'd say it's worth the money.
- Handle and wheels to make it easily transportable across rooms
- Sleek design
- Larger than most dehumidifiers
- Extraction rate: 17.53L per day at 20°C
- Capacity: 25L
- Weight: 16kg
7. Best portable dehumidifier: LONOVE Dehumidifier
Price: £40.99 | Buy now from Amazon
Weighing barely more than a bottle of water, the LONOVE 1L Dehumidifier can be moved around very easily to help you tackle damp around your home. With the ability to remove up to 350ml per day, this dehumidifier will be effective in small spaces such as a cupboard, small bedroom or bathroom. The tank can hold up to one litre and, when full, it automatically shuts off to conserve energy.
The LED display on the LONOVE also flashes yellow to let you know it’s full and has a very simple one-button control to turn on and off, though that does mean it lacks any extra features, such as a laundry mode or humidistat.
It’s fairly quiet in use so you won’t be disturbed if it comes on at night or you have a sleeping baby nearby, and it also won’t break the bank.
While the LONOVE isn’t suitable for larger spaces or bad cases of damp, it’s ideal for tackling condensation or damp issues in small, isolated areas around the home.
- Very light and portable
- Energy efficient
- Not efficient in large rooms
- No extra features
- Extraction rate: 350ml
- Capacity: 1L
- Power: 22.5w
8. Best whole house dehumidifier: Ebac 21L Dehumidifier 3850e
Price: £319.99 | Buy now from Amazon
“I’ve got an Ebac and it’s very good. I got it a few years ago and don’t use it that often, but it’s very useful for days in winter when it’s very cold and damp.”
“Our Ebac is constantly going. It amazes me how much water it collects. I don’t measure the humidity but can tell the difference in warmth and condensation levels on windows.”
The Ebac 21L Dehumidifier is said to be the only machine specifically designed for British climates. With a large extraction rate, this is a powerful dehumidifier that can eliminate condensation, damp and mould in homes with up to five bedrooms.
As with most refrigerants, it works better in warmer conditions but has been designed with an Intelligent Defrost system so it can work at temperatures as low as 3°C.
It comes with digital controls and an LED display, two extraction modes and a laundry setting. There’s also a timer of up to eight hours or you can set the device to monitor the humidity levels in the room, making it really energy efficient. There’s also an air purification mode.
The Ebac 3850e can be noisy, however there is a quiet mode (although the dehumidifier won’t work as effectively). The device is quite heavy (13kg), but it does come with a handle and, although the water tank is just 2.5 litres, you do have the option to drain it continuously.
- Designed for British climates
- Energy efficient
- Heavy and not easy to move around
- Small water tank
- Extraction rate: 21L
- Capacity: 2.5L
- Power: 320W
9. Best dehumidifier for saving energy: electriQ 12L Low Energy Dehumidifier CD12LE
Price: £149.98 | Buy now from Appliances Direct
The electriQ 12L has been designed to be energy efficient while still tackling damp issues effectively. In fact, it claims to save 40% of running costs compared with other standard dehumidifiers.
A compressor, this device is better suited to warm environments and comes with a 24-hour timer that turns it on and off when you need it as well as a humidistat to regulate the moisture in your home – with colourful LED lights that change with the humidity level. The electriQ 12L uses just 180 watts which will certainly keep your energy bills down.
The device has two fan speeds, a laundry setting and an advanced air purifier to ensure the air is clean and healthy. It can remove up to 12 litres a day into a four-litre tank to help tackle damp issues in flats and homes of up to three bedrooms.
You can opt for permanent drainage, but with castors it can be moved around which is helpful as it weighs a heavy 14kg. It’s not one of the quietest models around, but if you’re energy conscious this may be the one for you.
- Really low energy and cheap to run
- Advanced air purifier for clean air
- Isn’t as quiet as other models
- Not as effective at lower temperatures
- Extraction rate: 12L

10. Best quiet dehumidifier: MeacoDRY ABC 12L Dehumidifier
Price: From £159.99 | Buy now from Amazon
“We have the MeacoDry ABC Dehumidifier and can’t fault it. Excellent at drying clothes – we just put it on in the utility and the clothes on the dryers and it dries them really fast. We’ve got one on the landing and just pop it on for a couple of hours a day in winter. Never have any condensation on the windows."
“Our house really suffered last year with damp so we bought a MeacoDry ABC which is simply superb. In the first few days, it extracted 10 litres of water and we were able to run it overnight as it’s really quiet. No damp ever since and no noticeable increase in electricity bills.”
Meaco’s quietest compressor, the MeacoDry ABC, is just 35dB (barely louder than a whisper) but is still powerful with a 12-litre extraction rate. It’s great for small homes and flats if you’re short on space and will notice a noisy dehumidifier more easily.
The model (which also comes in 10-litre and 20-litre sizes) is really energy efficient, costing just 2.4p per hour based on 15.2p/kWh, while still effectively removing moisture from the air in warmer environments. Like most refrigerants, it doesn’t work as well in unheated rooms.
It comes with a small 2.6-litre tank for its size so it may need emptying regularly or you can buy a hose. Features include a 24-hour timer, two fan speeds, a variable humidistat and a laundry setting. It also has a child lock so there’s no risk of any settings being changed.
The MeacoDry ABC is compact and comes with a handle but doesn’t have any wheels. We love that it’s available in five colours so you can pick one to suit your décor.
- Really quiet
- Very energy efficient
- Not as effective in colder temperatures
- No wheels for moving around
- Extraction rate: 12L
- Capacity: 2.6L
- Power: 160w
Why do I need a dehumidifier?
Dark spots on your walls, condensation on your windows and patches of mould or mildew are all signs your house is suffering from damp. This happens when the humidity level regularly goes above 60%.
It can be caused by a more serious issue such as lack of ventilation, leaky pipes or poor insulation, but daily life does have an impact too – for instance cooking, showers and drying washing indoors.
Not only can it make your home look unattractive – and even smelly. But excess moisture can cause lasting damage to the wood and walls and, as dust mites and mould spurs thrive in humid conditions, they can cause problems for people with breathing issues and trigger allergies.
A dehumidifier will remove excess water from the air to dry out the room and they range in price from £30 to £450. Cheaper units tend to have a smaller capacity and don’t have extra features such as wheels, variable humidity levels or a laundry setting, but that may be fine if you only need it for a small space or a mild damp problem. The more expensive models tend to be energy efficient but they’re not always the most effective.
What should I look for in a dehumidifier?
While the aim of all dehumidifiers is to suck excess water from the air, there are two main models you can buy. Which one you go for will depend on where and how you will be using it.
This is the most common type of dehumidifier in the UK as it works best in higher temperatures, such as a heated home.
Refrigerants tend to be large and work similarly to your fridge at home – a fan draws warm, damp air into the dehumidifier which comes into contact with cold coils, then condensation forms and drips into the tank.
They don’t tend to work well in lower temperatures as the coils need to be colder than the air in the room and can start to freeze, but some models do work well in colder climates. Refrigerants are generally noisier than desiccants.
Desiccant dehumidifiers extract water using an absorbent material to draw moisture from the air. An internal heater warms it up and the moisture drips into the tank. They can be used in both warm and cold spaces, such as an unheated garage, but tend to release more heat into the room which you may not want in an already heated home.
Desiccants are ideal for a cold garage, loft or conservatory and are more effective than refrigerants but they do use more energy. As they don’t have a compressor, they are often quieter.
There is a third variation, which is less common – Peltier dehumidifiers use electricity to create a temperature difference and as the air passes through, it condenses and drips into the tank. It isn’t thought to be as powerful as a refrigerant or desiccant, but without a compressor it is quiet.
There are a few key features to think about when shopping for a dehumidifier:
- Capacity – this is the maximum amount of water the dehumidifier can extract in a day, generally ranging from 500ml to 25 litres. Small units are fine for occasional use or a small area, such as a cupboard. Around 12 litres is suitable for a small flat, medium-sized room or a mild damp problem. Up to 16 litres for a larger room or one that is used regularly for washing or cooking and units with a capacity of up to 20/25 litres can be used for whole homes. Desiccants are more powerful though so can be smaller.
- Water tank – this is how much water the unit can hold and ranges from around 250ml to six litres. The smaller it is, the more you’ll have to empty, though some models have a continuous drainage option through a hose.
- Humidity levels – relative humidity (RH) should be kept between 30 to 60% and most models have a built-in humidistat to keep the room at your chosen level. Devices with an auto setting monitor and adjusts the moisture levels in the room, which can save on electricity.
- Controls – more basic models come with a manual control that turns on and off, while others have digital displays with more features, such as a timer and laundry mode, which removes excess moisture that comes from drying laundry indoors and dries your clothes quicker. It can be a cheaper alternative to a tumble dryer.
- Fan speeds – some have just one speed for continuous drying while others have up to three, which is handy if you want to adjust it for faster drying.
- Portability – a model with a handle or wheels/castors (or both) will be easier to move around, especially if you buy a large, heavy model.
- Noise – generally speaking dehumidifiers are rated around 40 to 60dB, which is the same as a normal conversation. There are quieter models, ranging from around 30dB (same as a whisper). If you run it at a lower fan speed it will make less noise, but it may be less effective.
- Cost to run – this will depend on what your energy tariff is, how you use the device and how much power it uses. Check the power usage which can range from around 22 to 600 watts – newer models tend to be more energy efficient, for example using 2.45p per hour based on 15.2p/kWh. Using a timer and humidistat will ensure it only comes on when needed. Desiccants tend to use more energy but are more powerful.
- Air filter – some models come with a HEPA filter which helps provide cleaner air in your home.
Where is the best place to put a dehumidifier?
To get the most out of your dehumidifier, work out where the source of the moisture is coming from and place it as near to there as possible. As they can be noisy and bulky, it’s tempting to hide it away in a corner but for larger rooms try and place it in the centre, making sure the dehumidifier is big enough to cover the whole room.
Saying that, dehumidifiers aren’t the most stylish looking devices so you’re unlikely to want a large unit sitting in the middle of your lounge – if the moisture is coming from a leaky window or front door, place it near there. To maintain airflow, make sure it’s not too close to a wall or furniture and keep it away from electrics.
What is the best time of day to use a dehumidifier?
Dehumidifiers need to be running for a few hours to be effective, so if you don’t want to rack up a huge energy bill it may be helpful to plan your usage.
Have a look at your energy tariff and see if your electricity is cheaper at certain times, such as at night. If so, you could time it to come on during those hours or when there is more humidity in the air such as when your heating is on, after a shower or bath, when drying clothes or cooking.
A device with an auto setting will be more efficient too as it will only come on when the humidity levels go above your RH setting.
What dehumidifier is best?
We believe the Pro Breeze 1500ml Dehumidifier is a great all-round home dehumidifier. It’s very compact and quiet, with a 500ml extraction rate, and is effective for small spaces – at a really affordable price.
