MeacoDry Arete Two 12L
The unit we'd buy with our own money. It hits its humidity target and then genuinely idles rather than cycling loudly, which is why people are happy to leave it running on a landing overnight. Laundry mode is the best implementation of the feature we've used.
Pros
- Quietest 12L unit on the market at around 35 dB on low
- Excellent laundry mode with automatic humidity targeting
- HEPA filtration built in
- Very low power draw for the extraction rate
Cons
- Premium price
- Tank slightly awkward to refit
Who it's for: One dehumidifier for a whole two or three-bed home

If the Meaco is out of budget, this does 90% of the job for half the money. The compromise is noise: fine in a hallway, kitchen or utility, less pleasant in a bedroom while you sleep.
Pros
- Full 12L/day extraction at half the price of premium units
- Continuous drain port included
- Simple humidistat and 24-hour timer
- Castors for moving between rooms
Cons
- Noisier than the Meaco at around 44 dB
- Plainer controls and display
Who it's for: Most households — the value pick
Check Price on Amazon UK →EcoAir DD1 Simple Desiccant
The right tool for cold spaces, and the wrong one for a heated bedroom. Below about 15°C a compressor's extraction collapses while this carries on regardless — but you pay for that in electricity, so match it to the space.
Pros
- Works down to 1°C where compressors fail
- Warms the room slightly as it runs
- Light at around 6kg — easy to carry
- Excellent for garages, conservatories and caravans
Cons
- Higher power draw (around 300–650W)
- Fan noise is more constant
Who it's for: Unheated spaces — garage, conservatory, caravan, cold hallway
Check Price on Amazon UK →Pro Breeze 12L Dehumidifier
The safe middle choice. Nothing about it is class-leading, but it extracts what it claims, the controls are obvious, and spares and support are easy to find.
Pros
- Reliable, widely available and well supported
- Auto shut-off with a full-tank indicator
- Laundry mode included
- Continuous drainage option
Cons
- Middling noise level
- Filter needs regular rinsing
Who it's for: A dependable all-rounder between budget and premium
Check Price on Amazon UK →MeacoDry Arete One 6L
If the problem is one damp bedroom rather than a whole house, this is a better buy than a bigger unit. Quiet enough that most people forget it's on, and it holds a bedroom at 50% RH without effort.
Pros
- Very quiet — usable in a bedroom overnight
- Compact footprint
- Sleep mode dims the display fully
- Low running cost
Cons
- 6L/day is not enough for a whole house
- Small tank needs emptying more often
Who it's for: A single bedroom, nursery or small flat
Check Price on Amazon UK →Dreo 20L Dehumidifier
Buy this only if you genuinely have the volume to justify it. In a large house or after a leak it clears moisture dramatically faster than a 12L unit; in a two-bed flat it just costs more and takes up space.
Pros
- 20L/day handles four-bed houses and serious damp
- Large tank plus continuous drain
- App control and scheduling
- Fast recovery after a wet washing load
Cons
- Physically big
- Overkill for a flat
Who it's for: Four-bed houses, basements and properties with a real damp problem
Check Price on Amazon UK →NETTA Mini Dehumidifier
Understand what this is: a cupboard product, not a room product. In a wardrobe or small en-suite it stops the musty smell and the mildew on shoes. Expecting it to dry a bedroom will only disappoint.
Pros
- Tiny and near-silent Peltier design
- Ideal for a wardrobe, en-suite or caravan locker
- Very low power draw
- Cheap enough to buy two
Cons
- Extraction is a fraction of a compressor unit
- Not a room solution
Who it's for: Wardrobes, cupboards, en-suites and small enclosed spaces

What size dehumidifier do you need?
| Property | Capacity | Typical price |
|---|---|---|
| Wardrobe / cupboard | Mini (Peltier) | £35–£55 |
| One bedroom / studio | 6L/day | £110–£150 |
| 1–2 bed flat | 8–10L/day | £90–£160 |
| 2–3 bed house | 12L/day | £85–£200 |
| 4+ bed house | 20L/day | £180–£230 |
| Garage / conservatory | Desiccant | £130–£170 |
When in doubt, size up. An oversized unit reaches target humidity and idles; an undersized one runs constantly and never gets there.
Running costs compared (24.5p/kWh)
| Type | Power | Per hour | 6h/day, per month |
|---|---|---|---|
| Mini (Peltier) | 25W | 0.6p | ~£1.10 |
| 6L compressor | 140W | 3.4p | ~£6.20 |
| 12L compressor | 185W | 4.5p | ~£8.20 |
| 20L compressor | 300W | 7.4p | ~£13.20 |
| Desiccant | 500W | 12.3p | ~£22.10 |
Real-world costs are usually lower, because a humidistat lets the unit idle for much of the time once the room is dry. Full running cost breakdown →
How to use a dehumidifier effectively
- Set the humidistat to 50% RH. Lower wastes electricity and dries the air uncomfortably.
- Close the doors and windows of the room being dried — otherwise you are dehumidifying the street.
- Stand it centrally with 20–30cm clearance around the intake and outlet.
- Run it hardest where moisture is produced: kitchen, bathroom and wherever laundry dries.
- Use the continuous drain hose into a sink if you don't want to empty the tank daily.
- Rinse the filter monthly — a clogged filter cuts extraction noticeably.
- Keep it running through the whole damp season rather than switching on only when windows stream.

Buying checklist
- Capacity matched to property size (see the table above).
- Humidistat, not just a timer — this is what controls the running cost.
- Noise rating under 40 dB if it will run in a bedroom or living room.
- Continuous drain port if you want to run it unattended.
- Laundry mode if you dry clothes indoors.
- Castors and a decent handle if it will move between rooms.
- Auto-defrost on any compressor unit used below 15°C.
- Washable filter rather than a consumable cartridge.
Buying advice
Buy for the coldest room, not the average one
