BRITAIN suffers from a naturally humid climate. Unfortunately, we get cold and humidity here. Aren't we lucky? So, picking up one of the best dehumidifiers can be a world of help, especially in the winter months, to help avoid dampness and mould entering your home.
I’ve been a fan of dehumidifying my one-bed flat ever since I read about the dangers of drying clothes indoors, either on a radiator or on a clothes horse. During the winter months, drying clothes indoors, with the windows closed, is a must, but it can lead to a build-up of moisture, which can then trigger allergies and dampness in the home, leading to mould. Plus, even everyday essentials like steamy boiling the kettle can add to the rise in potential damp problems.

Within days of plugging my dehumidifier in, I had filled up an entire tank of water; I was in shock!
Dehumidifiers generally help to improve the quality of the air around you, by removing excess moisture from the air that encourages the growth of mould spores, dampness and bacteria.
So, they’re a pretty useful machine to invest in. But which is best for you and your home? I gave a range of dehumidifiers a try, from the cheap and cheerful to the expensive and chic, and these models came out on top.

- Meaco 20L Low Energy Dehumidifier & Air Purifier, £259.99 at John Lewis - buy here
This Meaco dehumidifier aims to reduce moisture in your home without costing you the earth in electricity bills.
Meaco says this uses 255 Watts of power to get the job done, which would cost you 7p per hour (assuming 34p/kWh).
And apparently, this is plenty, according to happy customers.
This low-energy machine has been praised for its ability to reduce condensation on windows and as a help for drying washing on the rack.
MeacoDry Arete One 12L Dehumidifier

- MeacoDry Arete One 12L, £190 from Argos -buy here
Pros:Tailored for UK climate, energy efficient, very easy to use
Cons:Upfront cost, styling
Rating: 5/5
The result of five years of research and development, including consultation with its customers about what they liked and didn’t like about the brand’s previous Dehumidifiers, the Arete One is a compact machine that looks like the love child between a shredder and a kitchen bin (and not in a bad way!).
It has been specifically designed to cope with British conditions, with a relative humidity of 60% for temperatures between 10°C and 20°C, and it really shows in operation.
It’s a powerful 12L compressor machine with an accurate, advanced humidistat (which we verified independently), which, rather than constantly checking the humidity, takes its reading every 30 minutes and adjusts its output accordingly, shutting down in between to save energy.
Apart from its outstanding performance, we loved the straightforward interface of the Arete One.
You have a power button, a daily use button, a setting for drying clothes and a night mode. A couple of button pushes will put the machine in Smart Humidity Mode, which will take the air down to 55% humidity and switch off, although you can adjust the levels according to your needs. If it detects levels have risen again, it will kick back into life with the fan speed and compressor automatically adjusting to moisture levels.
Night mode is quiet; there are no blinking lights, no obtrusive beeps and the speed of the fan powers down to its quietest mode.
Backing all this up is good portability with easy-rolling wheels and a retractable carry handle, so you can transport it quickly between rooms or get it upstairs without too much effort.
You can rest easy with this purchase since it's got an outstanding 4.9-star rating on Argos with praises of its 'great ease of use' and notable effectivity, claiming that they had 'no more condensation.'

Von Haus

- Von Haus 12l dehumidifier, £139.99 - buy here
Pros: Powerful, nice LED screen, easy to move with smooth wheels
Cons: Not as quiet as others
Rating: 4.5/5
If you’re after a compact, neat-looking dehumidifier, then this Von Haus machine is a good option. It can extract up to 12l of water a day in its 2l tank, which is pretty impressive, and it’s not too large, coming up to about knee height.
There’s a drainage hose to drain out the water continually if you fancy this, however, you can also remove the tank and empty it this way instead if you prefer.
In terms of sound, I have heard quieter dehumidifiers, but it’s still fairly quiet and won’t disturb you if you’re working or need peace. And, I love how smooth the wheels are on this so it’s easy to move around.
The sleek LED display is easy to control and it has a clear water-full light signal at the top of the machine, so you know when the tank is full and when it needs emptying. It’s very sleek and would sit nicely in a flat I reckon; in fact, it looked lovely in my flat as it wasn’t overbearing. Added to this, there’s a two-year warranty for peace of mind.

Wessex

- Wessex 12l Dehumidifier, £129.98 at Toolstation - buy here
Pros: Laundry mode to suck moisture from wet clothes, 12-hour timer, compact
Cons: Tricky to lift
Rating: 4.5/5
This Wessex dehumidifier is a really neat, compact and tidy machine. The 2l tank has an auto shut-off, so when the tank is full, it simply stops extracting, and there’s no worry of potential overflow or leakage.
The dehumidifier has three power modes (Auto, Laundry and Sleep) and also a 12-hour timer, so it will shut off itself should you forget to switch it off.
The high-power Laundry mode also means that when wet washing is drying indoors, it will pull in more air and more moisture, whilst also increasing the warmth of the air that leaves the machine; simply direct the dehumidifier towards your washing.
At night, switch to Sleep mode to lessen the noise, but generally, this is a quiet machine, and I can’t see it causing too much disturbance.
The wheels glide easily, making it easy to move around. However, there is only one back lifting handle, which makes it harder to lift.

Bostik Breathe
16
- Bostik Breathe, £15.50 at Amazon - buy here
Pros: Doesn't require electricity, small and silent, great for small spaces
Cons: Small, have to buy tablets
Rating: 4/5
A slightly different style of dehumidifier is this one by Bostik, which doesn’t need to be plugged in, so it really can be placed anywhere; inside cupboards, wardrobes, on bathroom shelves…you name it! Bostik calls this a humidity absorber rather than a dehumidifier. As the name suggests, its aim is to help you breathe more easily, by clearing the air of moisture and humidity.
Essentially, you pop in two of the Bostik moisture absorber tablets, which Bostik say can provide up to 33% more absorption than a standard moisture absorber that only contains one tablet, and let the 1.2l tank fill up with water from the air. Considering how small this is, the tank is a decent size.
You can just use one tablet, for smaller spaces, however using two tablets covers a slightly larger area of up to 25m2. Just to note, this does come with two tablets. A pitfall of this machine is that you will need to keep buying the tablets so it adds an extra expense in that regard. According to Bostik, tablets will last up to four months but this does depend on the humidity levels in the room so if your home is very humid, then you might need to top them up sooner.
Another big positive of this Bostik machine is mostly made from recycled materials, so it’s planet friendly too.
This would also be great for caravans and sheds, or areas lacking in a plug.

Swan Low Energy Dehumidifier
16
- Swan 20 Litre Low Energy Dehumidifier, £189.99 - buy here
Pros: Low energy, on wheels, super chic
Cons: More expensive than others
Rating: 5/5
For a super-chic design, this is the dehumidifier you need. It can extract up to 20l of water a day, with a 4l tank that shuts off automatically when it’s full, so there's no leakage.
This dehumidifier comes in super tight packaging and is very heavy. But, when it’s out, the wheels glide easily and the lifting handles are easy to use and strong, so it’s simple to move.
The Swan looks so tidy it wouldn't look out of place in any room of the house.
It’s also low-energy, which means less of an impact on the electricity bills; something I am a big fan of.
I love the easy-to-use LED display and control panel which makes this feel a little more high-tech and swanky. There is also a built-in timer so you can have it switch off when you wish, without having to remember.
Plus, I noticed how quiet this machine was making it easy to leave on at night. There’s also a low and high speed option and the extractor fan cover opens when you turn it on.

Princess 10L Dehumidifier
- Princess 10L Dehumidifier, £160 at Argos -buy here
Pros:Excellent clothes dryer, easy to roll around different rooms
Cons:Very noisy, awkward water tank
Rating: 3.5/5
This compressor offered a very useful level of extraction (10L), without costing the earth to run, with 205W of power usage and we found that it was very efficient in operation, particularly when drying clothes as there is a manual vent on top of the machine which you can use to direct the airflow towards your laundry to speed up drying time.
The humidistat was accurate, and there was good portability as the whole unit rolls well on carpet or hard flooring on quality castors, although it is a bit of an awkward beast if it’s travelling between floors in a property.
The timer function did fail once, but apart from that, we had no issues with it at all. Although the warning alarm for a full tank could be a little louder, and there were a number of occasions when the tank was full, we didn’t notice until we realised that it had automatically shut down.
In fact, the machine is very noisy, and that was what alerted us to the fact that the machine had powered down. The tank is a little difficult to extract when full, but the control panel was very easy to operate and read.
Seeing as this dehumidifier is available at a premium price, it's fair to want a premium-quality item. So, unsurprisingly this item comes in highly recommended from a store with an almost perfect 4.8-star rating.

Black + Decker BXEH60004G

- Black + Decker BXEH60004GB Dehumidifier, £72.01 from Amazon -buy here
Pros:Energy efficient, water tank capacity, styling
Cons:Hard-to-read control panel, not optimal portability
Rating: 4/5
This large compressor dehumidifier attempts to make itself a little less conspicuous with some nicely rounded edges, so you won’t be cursing it if you’re using it in a small room and need to work around it.
We really liked the circular LED on the front of the machine, which is lit in three different colours according to the room’s current humidity level: yellow (30-49%), green (50-69%) and red (70-80%).
It offers a good balance between extraction capability and water tank capacity. It can pull 20L of moisture from the air a day and store it in a generous 6.5L water tank, which automatically switches the machine off when it reaches capacity, or after 24 hours - whichever comes first.
This means it’s an excellent machine if you want it to be working in an area where you won’t be able to constantly monitor it, for example, a boat, basem*nt or rental property, as you can switch it on, let it get on with the job and return to empty the tank when it’s convenient.
We would have liked a way to check the water levels in the tank from the front of the appliance instead of having to turn it around, but that’s a small gripe in the grand scheme of things.
Portability was okay, although the side handles make it harder to carry the unit up and down a flight of stairs, which isn’t ideal considering it’s quite a heavy machine.
In terms of overall usability, the control panel is clear and organised, and the buttons are responsive, but the fact that the functions are written in grey on a grey panel background makes them hard to read.
Having a 4.5-star rating, it's no surprise that customers call it 'perfect' and an 'amazing product' and being 'compact and quiet', we're sure you'll be just as happy with your purchase.

Honeywell 33L TP
16
- The Honeywell 33L TP Dehumidifier, £198.95 from Airconcentre -buy here
Pros:Well-designed controls, energy efficiency
Cons:Water tank could be too small for some users
Rating: 4.5/5
As soon as we powered this 33L compressor on, its humidistat was able to give us a very accurate reading of the current humidity percentage in the room and then set about getting that percentage down to the target level.
Programming this level was straightforward, and the control panel itself was nicely laid out and easy to navigate.
This is a very efficient machine, and we can back up the manufacturer's 33L extraction capacity claim. However, we could have done with a slightly larger water tank because if you’re faced with high humidity levels or a big load of washing, you’ll probably need to monitor the machine’s water tank alert regularly and empty the tank frequently.
For many, the smaller water tank will be a trade-off they’re willing to make as the unit is a nice size and won’t dominate the room it’s in. The tank itself is easy to remove, drain and replace and the unit does have a continuous drainage feature.
With a robust grab handle and multi-directional castors, we had no issues with portability on the ground floor, and its lightweight also made it a doodle to get it upstairs.
The product comes with a 2-year warranty to give you that extra piece of mind. If that's not enough, it currently has a 5-star rating, with the reviewer acknowledging they had condensation and mould issues, but this device 'solved the problem completely.'

DUUX Bora Smart Dehumidifier
- DUUX Bora Smart Dehumidifier, £239 from Amazon -buy here
Pros:Quiet operation, energy efficient, looks good
Cons:App is not very user-friendly, very heavy
Rating: 3.5/5
It makes a lot of sense to have a “smart” dehumidifier as it’s one of those appliances where continuous monitoring can be beneficial in terms of checking in with humidity levels and also seeing how full the tank is. However, it seems the Dutch manufacturer has been a little too eager to label their product “smart” because, apart from turning the machine on and off, the app is pretty much redundant and will only tell you what you already know - the active settings you have already programmed into the control panel.
The company have missed a trick in not letting you be able to control and interact with the machine via your smartphone, and the fact that the app doesn’t even warn you when the water tank is full seems ridiculous.
Smart grumbles aside, the machine is hugely efficient, whether dealing with damp, mould, or laundry, and a very accurate humidistat with good power and an efficient compressor combine to deliver a guaranteed 20L of daily extraction, which is collected in a big 4L tank that we had no issues emptying.
The control panel is clear, the wheels are robust, and the handle, which tucks away out of sight easily, is sturdy - but then it needs to be as this is averyheavy machine

Blaupunkt compact dehumidifier

- Blaupunkt compact dehumidifier, £54.99, from OnBuy - buy here
Pros: easy to use, quiet, great value for money
Cons: doesn't have the capacity for larger rooms
Rating: 4.5/5
This model - designed by German manufacturer Blaupunkt - I found was the second most effective at extracting water, collecting equivalent to 105ml over 24 hours.
It was easy to use, with a slide-out water tray with a removable lid which could be fully emptied and removable air filter covers making it a breeze to clean when the time came.
I found that it was slightly louder than most of the other products I tested and made a deep whirring sound, which was less annoying than the whining buzz of some of the other models.
The water tray seemed well-made, but the main body seemed cheap and flimsy upon handling, with the edges of the casing failing to line up properly.
I was surprised at how effective it was at extracting water and for that reason, I rank it the best value for money.

Xaxazon 1000ml small dehumidifier

Pros: Most effective at extracting water, stylish, adjustable colour LED, easy to clean
Cons: Noisy, may topple over when no water in tray
Rating: 4/5
This model was the most effective at extracting water, collecting around 123ml in 24 hours – twice as much as the worst model I tested.
It also looked fairly stylish, included adjustable colour-change LED lights which I found fun to mess around with, and it was easy to empty and clean, with a removable drip tray and air filter covers - bonus points for making my life easier.
But it was noisy when on, and the design was top-heavy, which meant it tended to topple over when there was no water in it or the tray was removed.

Challenge 0.5l mini dehumidifier

- Challenge 0.5l mini dehumidifier, £50 - from Argos
Pros: Removable air filter
Cons: Not very effective, impossible to clean out fully
Rating: 3/5
This was the smallest and by far the quietest model tested - it hardly made any noise.
It wasn’t very effective though, only extracting equivalent to 84ml over 24 hours.
It got extra points for having a removable air filter cover, which means you can clean out dust that gets trapped inside, and for having an easy-to-remove drip tray.
But it lost points because you can only empty the tray via a hole filled by a rubber plug, meaning it is impossible to clean out fully.

Pros: Feels robust, relatively quiet, easy to use
Cons: poorly made power outlet can't be fully cleaned, second least effective model
Rating: 2.5/5
This one looked very similar to the Challenge model tested from Argos but felt more robust.
However, the power outlet on the model was poorly made and I had to remove loose plastic from it.
The model was relatively quiet and not distracting.
Plus, it was also easy to use with a removable drawer-style water tray.
But I had to remove points because the tray could only be emptied via a hole in the lid, so I couldn't fully clean it, and there was no way of removing the air filter cover for cleaning.
It was the second least effective model tested, extracting only around 78ml of water in 24 hours.

Rating: 2/5
This On Buy dehumidifier was easy to set up and use, with a simple on/off switch and a water tray with a removable lid, which can be fully emptied and cleaned.
But again I had to take points away for ease of use because it was very fiddly to put the tray lid back on again.
It was pretty quiet but I didn't think it was doing much.
That showed when I emptied the dehumidifier, as it collected the least at just 63ml per 24 hours.
I rated this one poorly for value for money, as it just didn’t work very well.

Rating: 3.5/5
Lots of dehumidifiers look ugly, but I liked this Vazzidea one with its stylish round black body and adjustable LED colour-change lights, which shine through the water tray.
Unfortunately, the fancy design makes emptying it quite difficult, as I had to screw off the top to access the water tray.
The round shape of the tray also makes it tricky to pour away without spills, as there is no spout.
I found this one's noise quite annoying—it made a whining, buzzing sound, and I couldn't quite zone out.
But it was one of the more effective models tested, extracting equivalent to 96ml of water over 24 hours.

- Conopu Dehumidifier, £39.99
£49.99- buy from Amazon
Pros: 8p for six hours, small, great for small spaces
Cons: Small, no laundry drying mode
Rating: 2.5/5
Dehumidifiers are also a good way to prevent mould and dampness in homes, and I've been trying to avoid using my storage heaters, which cost 77p an hour to run.
So I decided to turn my attempts towards using a dehumidifier to dry my clothes while combating the cost. However, I found when it came to drying my laundry this particular dehumidifier was a flop.
While it promises to remove around 450ml, and the tank was certainly full after each cycle, it just didn't seem to have the ability to help dry my items.
Although it was much cheaper than my storage heater, it just didn't work for me. However, that's not to say it won't have a positive impact on mould buildup in your home.

Not up to speed on dehumidifiers? Chris Michael, Managing Director at Meaco, and somewhat of an oracle on all things dehumidifier-related, shares some tips below…
What should we look for in a dehumidifier?
“Energy efficiency is probably the most important consideration at present given the ongoing high electricity costs,” says Chris.
“By checking the appliance's wattage and size (typically 10, 12, 20 and 25 litres) you can compare models to identify the most energy-efficient model for the property. It’s a false economy to buy a cheap dehumidifier that has a high wattage as the running costs will quickly surpass the initial purchase cost savings when compared to a low energy model.”
Chris adds that a dehumidifier with a laundry mode is also a key consideration, ‘especially as households increasingly look for ways to dry washing indoors instead of using energy-guzzling tumble dryers’.
“In laundry mode, the machine runs for six hours, which is the average time it needs to dry a load of washing, then switches itself off to save on energy bills.”
Plus, how noisy is your potential dehumidifier? As these machines are on most of the day, you’ll want one that’s fairly quiet.
“Most dehumidifiers are placed in hallways or on landings and are often switched on overnight to dry wet washing. Low noise is important so that people can sleep and live with these appliances,” says Chris.
What size dehumidifier is best for your property?
According to Chris, the general guidance for dehumidifier sizing is:
- Up to 2 bedroom flat house = 10L
- Up to 3 bedroom house = 12L
- Up to 4 bedroom house = 20L
- Up to 5 bedrooms or larger = 25L
“However, the number of occupants and how damp the property gets are other variables to consider when choosing a more powerful model than shown above,” adds Chris.
How much does it cost to run a dehumidifier?
This will depend on your appliance's litre capacity, the wattage it operates at, and some quick calculations involving the average unit price for dual fuel customers on standard variable tariffs, which is 34p kWh.
So, basing our costs on the average price of 34p kWh, a 12L appliance will use around 160 watts, which translates to 0.16 kWh, so an hour’s usage will cost a little over 5p an hour.
Bear in mind, though, that many of our featured dehumidifiers have smart modes and an in-built humidistat, so they won’t be running around the clock.
Where to buy dehumidifiers in the UK?
We've gone and done some of the hard work for you by testing dehumidifiers for you, but we know as well as you that there's a huge range of dehumidifiers on the market, and it's likely you'll want to test out a few of them for yourself.
We've put together a list for anyone whos looking to do a little bit more shopping around before making a purchase.
How much do dehumidifiers cost?
As seen in this article, dehumidifiers, like all products, can come in a wide variety of prices. From what we found, dehumidifiers aren't the cheapest household accessories. You'll be looking at around £50 for some of the cheaper variants, and it can range up to a few hundred for any on the more technical side that comes with more functionality.
Costs don't end at just the purchase, unfortunately. However, most dehumidifiers are fairly cost-conscious in running as it works out to be around 5p an hour.
What does a dehumidifier do?
Much like a tumble dryer extracts moisture from clothes, a dehumidifier will extract moisture from the air by drawing warm, damp air inside and releasing drier air back into the space. At the same time, the condensation is collected in a tank, which the user can then empty.
All the machines we tested were compressor machines (the most popular type of dehumidifier for the British climate). That means that they will suck the air in over-cooled coils so that the water condenses and is collected in the tank. The processed air is then vented out of the machine as dry, warm air.
Do dehumidifierswork?
They really do, although don’t forget that they're more effective in a heated room than an unheated room because they need the air in the room to be warmer than the cold surface within the dehumidifier.
Compressor appliances work best at around 20ºC, which happens to be the average UK household temperature.
For the machine to work optimally, you need to ensure that doors and windows are closed when it’s running. If windows are open, your dehumidifier will be working harder to try to dehumidify a greater area.
Is there an alternative to dehumidifiers?
The short answer is yes. There are alternatives to using a dehumidifier, but none of them are as simple as slapping a box in a room and watching the moisture collect.
The first and easiest way is to remove moisture build-up by increasing ventilation in the room. However, this isn't always as easy as it seems, as you may need to leave windows open, which isn't always an option during wintertime.
Another way is to ensure there are no gaps or leaks in the seals around your windows, as that can allow moisture and outside humidity to build up, leading to a buildup of mould and dampness.
Can a dehumidifier remove dampness?
This is one of the appliance’s main functions because the air in your house will contain moisture or humidity.
Mould is likely to occur if the relative humidity indoors is 70% or more for long periods, so you need the machine to bring that humidity down to between 30 and 60%, especially during the colder months of the year.
How effective the machine is at doing this depends on how well the room is sealed.
For example, if you’re using a machine in a basem*nt and a door is constantly being opened, it will let fresh, moisture-laden air into the room, so the dehumidification process will take longer. This is why, to optimise the efficiency of the machine and rid an area of dampness, you need to keep the room totally enclosed.
Do dehumidifiers help with dust?
A dehumidifier draws air through it to extract the moisture from the air and, in doing so, will draw in dust, which is why all appliances are fitted with high-quality HEPA filters or a filter with an anti-bacterial coating, which is there to catch dust and stop it from entering the inner workings and causing maintenance problems.
Most manufacturers recommend that the filters be removed and cleaned regularly to keep the machine operating efficiently.
