In stockDevola DVHA20L 20L/Day Hybrid Dehumidifier & Air Purifier Review
Our verdict: The best choice if you want a single machine that tackles damp and cleans the air at the same time — genuinely useful in a home with allergies, pets, or a room that also collects cooking odours, not just a marketing bundle of two gadgets in one box.
The Devola DVHA20L is Devola's flagship model, and the only dehumidifier in this range that doubles as a proper air purifier rather than just moving damp air around. If you've been searching for a dehumidifier that also filters the air — because of allergies, a pet, or a kitchen that never quite loses its cooking smell — this is the model built specifically for that brief.

If you just want damp and condensation under control without paying for HEPA/UV-C/ionizer features you might not use, the Devola DV12L covers a smaller room for a lot less money and is a Which? Great Value Award winner.
Devola dehumidifier: pros and cons in detail
The DVHA20L earns its premium over a standard 20L compressor dehumidifier almost entirely through the air purification stack: a True HEPA filter, UV-C lamp and ionizer running in combination is a genuinely different tier of feature to a basic dust filter, and the real-time PM2.5 sensor means you're not just told the air is cleaner, you can watch it happen. The trade-offs are the small 2.89-litre tank relative to its 20-litre daily extraction — meaning more frequent emptying at full output than you'd expect — and the absence of any app or Wi-Fi control, which some buyers in this price bracket will miss. Neither is a dealbreaker for the core use case (damp control plus genuinely useful air purification), but they're the two things to weigh against the simpler Devola DV12L if you don't need the air-quality features.

About Devola's moisture extractor range
Devola is a UK-focused heating and cooling brand that has built its catalogue almost entirely around the British damp-and-condensation problem: dehumidifiers, panel heaters and air purifiers sold direct to UK homes rather than repackaged from a global catalogue. The DVHA20L sits at the top of its dehumidifier range, above the simpler 12L and 20L compressor-only models, and is positioned specifically against hybrid dehumidifier/purifier units from bigger names like Devola's own 2-in-1 competitors and the Meaco Arete range.
What separates the DVHA20L from a standard 20L compressor unit is the second half of its job: alongside the compressor and refrigerant coil that pull moisture out of the air, it runs a True HEPA filter, a UV-C lamp and an ionizer in sequence, then reports back on air quality through a PM2.5 sensor with a colour-coded LED. In practice that means the unit is doing two jobs most households would otherwise buy two separate appliances for.
Who this Devola damp extractor is for, and how to use it at home
For everyday damp control, the DVHA20L runs best in Auto mode, where the intelligent humidity sensor holds the room at a target percentage rather than running flat-out continuously — the same approach used by pricier 20L rivals to keep running costs down. In a bathroom or kitchen prone to condensation, this is the mode to leave it on permanently.
For drying laundry indoors, switch to Laundry mode: it runs at full extraction with the louvre swinging to spread airflow evenly across a clothes airer, and most owners report a full wash load drying in under a day even through a British winter.
The Air Purifying mode is where this model earns its price premium over a standard compressor dehumidifier: it runs the fan, HEPA filter, UV-C lamp and ionizer without necessarily running the compressor, so you can use it purely to freshen a room in summer when humidity isn't the problem. The PM2.5 LED indicator (blue/green/red depending on air quality) makes this genuinely useful rather than a box-ticking feature — you can watch the colour shift as the air clears after cooking or when pollen is high outdoors.
Best placement is central in the room, away from walls and curtains, with the swing louvre left on so the purified, drier air circulates rather than settling near the unit itself. In a bedroom, run it on Sleep mode overnight, which dims the display and drops fan noise.
What UK buyers say about this Devola moisture control unit
Amazon reviewers rate this the highest-scoring dehumidifier in Devola's range, with owners consistently highlighting how noticeably cleaner and clearer the air feels within the first hour of running it — several specifically call out the UV-C and ionizer combination as doing more than they expected from a dehumidifier. The most common criticism is the printed instructions, which some owners found too thin to explain the different modes clearly, and a few would have liked a spare filter included in the box rather than sold separately.

Our verdict on this Devola dehumidifier: 4.7/5
Buy the DVHA20L if air quality matters to you as much as damp control — allergy sufferers, homes with pets, or anyone who wants one machine instead of a dehumidifier and a separate air purifier cluttering the same room. If you only care about pulling moisture out of the air at the lowest possible price, the Devola DV12L or the Meaco Arete Two 20L will do that job for less, without the HEPA/UV-C/ionizer stack you'd be paying for and not using. For a whole-house 20L unit with a longer warranty and a companion app, the Meaco remains the safer all-rounder; the Devola wins specifically on the air-purification side of the brief.

A few extras that are genuinely useful with this model, not just upsells:
Replacement HEPA filter (compatible with Devola 20L hybrid range)
The True HEPA layer is what does the air-purification half of this machine's job, and it saturates with dust, pollen and pet dander over time — once it's clogged, the ionizer and UV-C lamp are cleaning air that's no longer passing through an effective filter, and airflow drops too, making the compressor work harder for the same dehumidifying result. Check the filter every few months and replace it sooner in a home with pets or heavy dust; a duller air-quality reading on the PM2.5 LED despite a clean-looking room is usually the first sign it needs swapping.

Frequently asked questions
Does the DVHA20L actually work as an air purifier, or is that just marketing?+
It's a genuine 2-in-1: a True HEPA filter, UV-C lamp and ionizer run independently of the dehumidifying function, and the built-in PM2.5 sensor gives real-time feedback rather than a fixed claim. Owner reviews specifically mention noticing clearer air and reduced dust within the first hour of use.
Is the 2.89-litre tank big enough for daily use?+
It's smaller than you'd expect for a 20L/day extraction rate, so on very humid days you may need to empty it more than once. The included continuous drainage hose solves this if you can route it to a drain or a large external container.
Does it need a Wi-Fi connection or an app?+
No — unlike some rival 20L models, the DVHA20L is controlled entirely from its own touch panel. That's a plus if you'd rather not deal with app pairing, but a downside if you specifically wanted remote control.
Will it work in an unheated conservatory or hallway?+
Yes, it continues extracting moisture down to 5°C, which is lower than many basic compressor units that stop being effective below about 10°C — though for a genuinely cold, unheated garage or shed, a desiccant model like the Meaco DD8L will still outperform it.
How often does the HEPA filter need replacing?+
Devola doesn't publish a fixed interval, but as a rule of thumb for a True HEPA filter running daily, budget on checking it every 3-6 months and replacing sooner in a home with pets or heavy dust — a fading air quality indicator or a visibly grey filter are both signs it's overdue.
