In stockDevola DV12L Low Energy Dehumidifier Review
Our verdict: The best-value small dehumidifier on the market right now for a single room or a flat — a genuine Which? award winner that costs less to buy and run than almost anything else in its class, without cutting corners on the basics.
The Devola DV12L is a Which? Great Value Award winner, and it's easy to see why once you compare its price against what it actually does: 12 litres/day of extraction, a genuinely quiet 36dB top speed, and running costs of around 5p an hour — cheaper than most rivals in its size class, and the model to look at first if you just need one room kept dry without overspending.

If you need to cover more than one room, or want HEPA/UV-C air purification alongside dehumidifying, the Devola DVHA20L covers up to 50m² and adds a full air-purifier stack for a higher but justified price.
Devola dehumidifier: pros and cons in detail
The DV12L's case rests on independently verified value: a Which? Great Value Award and Good Housekeeping Institute approval are not badges Devola can simply claim, and at under £150 with a 5p-an-hour running cost, it undercuts most rivals in its size class on both purchase price and running cost simultaneously. The trade-offs are exactly what you'd expect from a budget-focused 12-litre unit: a 2-litre tank that needs regular attention on the most humid days, and no air-purification features if that's part of what you're looking for. Neither undermines the core promise — quiet, effective, cheap-to-run damp control for a single room — which is exactly what the Which? award recognised it for.

About Devola's moisture extractor range
Devola built its dehumidifier range specifically around the everyday British damp problem — condensation on bedroom windows, a laundry room that never quite dries, a static caravan or box room that smells musty by October. The DV12L is the entry point into that range: a straightforward compressor dehumidifier without the air-purification extras of the flagship DVHA20L, aimed squarely at buyers who want one job done well rather than several done adequately.
That focus shows in the independent recognition it's picked up: a Which? Great Value Award in November 2025 and Good Housekeeping Institute approval for 2026, both awarded on tested performance rather than marketing claims. For a 12-litre unit costing under £150, that combination of independent validation is unusual — most budget dehumidifiers in this price bracket carry no third-party endorsement at all.
Who this Devola damp extractor is for, and how to use it at home
For a bedroom or box room with condensation on the windows, run the DV12L with the humidistat set to around 50-55%, the level most UK health guidance treats as the ceiling for avoiding dust mites and mould growth. The unit will cycle on and off automatically to hold that target rather than running continuously, which is what keeps the running cost down to roughly 5p an hour.
For drying laundry, switch to Laundry mode and place the unit next to a clothes airer with the door closed — reviewers consistently report a full wash load drying in under a day, some in as little as five or six hours in a small closed room. Because the tank is only 2 litres, expect to empty it once during a laundry-drying session on a full load.
In a static caravan, garage or unheated conservatory, this is one of the few compressor dehumidifiers in its price bracket rated to keep working down to 5°C — several verified buyers specifically bought it for exactly this use case (a garage recording studio and a static caravan both feature in genuine owner reviews) and reported it held humidity around 50% even when starting from over 80%.
Best placement is a central spot with a few centimetres of clearance for airflow, on a hard floor rather than carpet if possible, since the tank can drip slightly when removed for emptying.
What UK buyers say about this Devola moisture control unit
With nearly 900 ratings on Amazon.co.uk, this is one of the most reviewed small dehumidifiers on the market, and the pattern is consistent: owners repeatedly describe it as near-silent, effective at pulling a room from very high humidity down to a comfortable level within an hour or two, and considerably cheaper to run than a tumble dryer for drying laundry. The most common criticism is the small 2-litre tank needing more frequent emptying than owners expected on the most humid days, and a handful of buyers noted the unit isn't the true HEPA-filtered model some listings implied.

Our verdict on this Devola dehumidifier: 4.6/5
Buy the Devola DV12L if you need one room — a bedroom, box room, static caravan or garage — kept dry as cheaply as possible to buy and to run, and you don't need air purification on top. It's the strongest budget pick in this size class on the strength of its Which? Great Value Award alone. If you want the same brand's build quality but need to cover a bigger, open-plan space, step up to the Devola DVHA20L, which adds HEPA/UV-C air purification and roughly triples the daily extraction. If you specifically want a longer warranty and app control at a similar size, the Meaco Arete One 12L is the main alternative to compare it against.

A few extras that are genuinely useful with this model, not just upsells:
Digital room hygrometer
The DV12L's built-in humidity display is useful, but it only reads conditions right at the unit itself. A cheap hygrometer placed on a windowsill or shelf elsewhere in the room lets you confirm the target humidity is genuinely being reached across the whole space — particularly useful in a larger bedroom or a static caravan where humidity can vary noticeably from one corner to another.

Frequently asked questions
Is the Devola DV12L quiet enough for a bedroom overnight?+
Yes — 36dB(A) is its noise level at full speed, comparable to a quiet desk fan, and several owners specifically bought it for bedroom use without being disturbed by the noise.
Does it come with a HEPA filter?+
No — despite some retail listings implying air purification, this model is a dehumidifier only, with a basic washable dust filter. If you want HEPA air purification alongside dehumidifying, look at the [Devola DVHA20L](/reviews/devola-dvha20l/) instead.
How big a room will 12 litres a day cover?+
It's designed for a single room — a bedroom, box room, static caravan or garage — rather than a whole house. For an open-plan living space or persistent whole-home damp, the 20-litre Devola or Meaco models are a better match.
Is 2 litres a big enough tank?+
It's on the smaller side for a 12L/day rated machine — on a very humid day or during laundry drying, expect to empty it once or twice rather than leaving it unattended for 24 hours. The included drainage hose avoids this entirely if you can route it to a drain.
Will it work in a cold garage in winter?+
It continues extracting moisture down to 5°C, which covers most UK garages and unheated spaces through winter, though efficiency does drop compared with a warm room. For consistently sub-zero spaces, a desiccant dehumidifier like the Meaco DD8L is the better choice.
