Devola 12L/day Low Energy Dehumidifier, Quiet & Energy Efficient (costs less than 5p per hour) Dehumidifiers for Home, Laundry Drying Dehumidifier, Dust Filter -WHICH? GREAT VALUE AWARD

I'm really pleased with this. We were looking for something to help dry clothes in winter months, and this is working exactly as we'd hoped. We put it in a small room with the doors and windows closed, set it to target 35% humidity and within about 5 or 6 hours it's dry and for far less cost than running a tumble drier. The unit itself is compact and about as loud as a pedestal fan. I would prefer a larger water tank, but this one manages with one empty per washing load (our washer is 8kg). We don't use it as an air filter or for general dehumidification, I'm not sure how well ithe small water collection tank would do if you're looking to use it for a flat or small house (it's probably underpowered for much more than that). It would probably need regular emptying. Although it's auto shut off when full and inoffensive alarm means this probably wouldn't be too much of an issue. Bottom line? Good value for money, study compact build quality and works great for laundry.

Bought this unit for a small recording studio that is located outside in my garage. For the last two years the room had begun to smell with damp and excess humidity to the point where some electrics in the room started to fail. I’ve had this unit on every single day for a week and the humidity levels have dropped from 80+ to sitting just above 50%. Room feels and smells cleaner. Delighted with the results and can safely say the unit is worth every penny. Unit emits a very low fan noise which is ideal for the purpose of my room. Recorded vocals the other day with unit on and there was no leakage of sound into in-room mics. Great little unit if you don’t want something hardwired into the room and want to have something portable. Yesterday I brought it into my kitchen to dry a small load of washing which was hanging over chairs etc and clothes were dry very quickly. Highly recommend this unit for anyone looking for a damp and humidity problem.

They say £0.05 per hr to run and they are right works a dream, our box room is now our drying room and this dehumidifier works an absolutely amazing, gets the moisture out of the clothes , the room is like an oven when you walk in, saving a fortune by sacking off the dryer in the garage.easy to move round and light weight, very compact and simple to use also. So 10/10 from me.

This review is for the 12L per day unit. This dehumidifier is small about the size of a small side table/the size of a medium shredder (a little shorter than the arm of my sofa) but it seriously packs a punch. Within 30 minutes the living room humidity had dropped from 72% to 65% (with outdoor humidity at 89%) and the windows open. The unit is fairly heavy (for me, a 5ft 3 woman, who loathes the gym 😱), but I did manage to lift it out of the box (you could always cut the cardboard box down the side and wheel the unit out of it). After two weeks of use I have found a couple of design flaws, which I’ve reluctantly deducted a star for. 1. HEPA filter - Despite the description this does not have a HEPA filter. Now I’m going to search for a HEPA filter that will fit the unit (it should have been sold with one - the description said it was - or at least provide a link to buy the filter separately). 2. Room temperature - If the room temperature is below 20oc (and sometimes at 21oc) the unit freezes and cuts out (presumably to give it time to defrost). 3. Emptying water tank - Like other reviewers I agree there is a knack to re-inserting the water tank. You have to angle it slightly forward and down (once you’ve done it a couple of times it’s easy). It also does continue to drip when the tank is out/being emptied (I put a folded piece of kitchen towel there to absorb the water while I empty the tank. It’s also a good idea to put the unit on a hard surface, rather than a carpeted one, so that any splashes that occur while the tank is out can be easily dried). 4. This costs approximately (£0.05) 5p an hour to run (according to my smart meter on a British Gas standard tariff at November 2024). In summary this is one of the best things I’ve bought. Small/easy to store, an impressive performance and sold at a reasonable price. I wouldn’t hesitate to recommend this to anyone.

Bought this as it was a ‘which’ best buy, we are delighted with this purchase. We have bought several dehumidifiers over the years. Bought this dehumidifier specifically for our static caravan, ideal size for a confined space and it’s on wheels so perfect. The static feels so much better for it, especially when showering and cooking. Would highly recommend and would have no hesitation in buying again.

We’ve been using this dehumidifier daily since October, and so far it’s been solid. No faults, no drama. In the UK climate, those cheap moisture-absorbing tubs are basically useless — we tried them before and they’re a complete waste of money. This machine actually does the job. It’s been running every day for months and hasn’t missed a beat. It’s quiet enough to live with, energy-efficient, and you can genuinely see and feel the difference in humidity levels. Damp air gone. Clothes dry faster. No comparison to passive tub dehumidifiers. The main downside is the water tank size (wasn't sure at beginning if we will need bigger - and yes, to run for entire day you need bigger tank without emptying the water tank that often) . On wetter days we’ve had to empty it twice, which gets mildly annoying. Another minor negative: when it’s running, it creates a slight draft and the room can feel a bit colder. Not a deal-breaker, but noticeable. Overall verdict: reliable, effective, and actually fit for UK conditions. I wouldn’t even consider going back to dehumidifier tubs — they’re trash compared to this. If you want something that works and can run daily without issues, this is a good buy.

Very good and perfect for the size of room, it knocked the humidity down to a sensible level within an hour.

I bought this in November 2025 so this review is based on a few months of actual use rather than first impressions. My main reasons for buying it were to (a) try and reduce mositure levels in my kitchen, and (b) help with drying clothes indoors in the winter months. Overall I would say that it has helped with both. This is a pretty compact appliance that is easy to move around as required, although a little heavy if you want to move it up and down stairs (but that could just be a problem for me since I’m not as young as I used to be!). The controls are simple and the noise level low enough to become part of the background after a while. It is solidly built and so far nothing has happened to make me think that it is unreliable in any way. It certainly does remove moisture from the air but the reservoir is large enough for me to use it for around 10 hours without having to empty it. Since I don’t have a smart meter I cannot give any accurate views on its energy efficiency other than to say that it doesn’t appear to have had a major impact on my quarterly bills despite being used for several months a day during the winter months. Any impact has been partly offset by the fact that it certainly speeds up clothes drying so I don’t need to use my gas central heating as much to do this. Overall this has done what I was looking for.
