Quiet everyday
MeacoDry Arete One 12L
The same quiet Arete One body as the 10 L, stepped up to Meaco’s 12 L table. At 20 °C / 60 % RH the official take is 5.23 L/day — the everyday heated-flat figure. At 10 °C / 60 % RH it falls to 1.95 L/day. That is the everyday heated-flat compressor in this guide, Compare it with the OmniDry 12 L on price and documentation.

The Arete One 12 L is the machine most UK flats in this guide should be compared against. Meaco rates it at 12.18 litres per day at 30 °C / 80 % RH. That is the carton headline. At 20 °C / 60 % RH the same official table is 5.23 litres — the useful figure for a heated living room. At 10 °C / 60 % RH it is 1.95 litres. A heated living room usually sits between those lab points; shop with the cooler row, not the carton headline.
Noise is the same published pair as the 10 L: 35 and 38 dB(A). Power at 20 °C / 60 % RH is 151 W. The tank is still 2.5 litres. Night mode and laundry mode are on the sheet, with a 40–70 % humidistat. Auto-restart, child lock, castors and H13 HEPA are included. The body is the same 472 × 319 × 237 mm shell as the 10 L. Weight is 10.9 kg, so the step up from 10 L is capacity, not bulk.
Laundry mode on Arete holds the unit in a drying cycle rather than a humidity target. That is useful in a closed bedroom or living room with an airer. It will not match a condenser tumble dryer on a wet Sunday, and Meaco does not claim that it will. Continuous drain is the way to run a long laundry day without hovering over the 2.5 L tank; the hose is a 12.5 mm garden fitting you supply.
Arete Two 12 L, on the same claimed litre class, adds a DC motor, a third fan speed (up to 140 m³/h), app control, a timer and a louvre. At 20 °C / 60 % RH Meaco quotes 5.4 L/day on Two. Power at that point is 136 W on Two versus 151 W on One — extraction stays in the same band. If you do not need the app, One is the quieter-spec everyday buy in this list. The head-to-head that actually changes the money is One 12 L against the Pro Breeze OmniDry 12 L.
Published specification
Extraction figures and room sizes are manufacturer claims, often measured at warm/humid lab points. UK rooms are usually cooler, so real take is lower. We have not run our own lab tests.

Where it fits
- A 1–3 bed heated home that needs a dehumidifier in living space, not a garage.
- Buyers who will pay for Meaco’s extraction table, HEPA and five-year warranty rather than the cheaper 12 L.
Where it struggles
- The budget is the OmniDry’s band and you accept a thinner spec sheet.
- The room is unheated; read the EcoAir DD1 page instead.
On the sheet
- Meaco’s table puts the headline at 12.18 L/day at 30 °C / 80 % RH.
- At 20 °C / 80 % RH the same table is 8.33 L/day; at 20 °C / 60 % RH it is 5.23 L/day — the everyday heated-flat row.
- At 10 °C / 60 % RH the take is 1.95 L/day, so a cold spare room still starves a compressor.
- Published noise is 35–38 dB(A), with night mode and laundry mode.
- H13 HEPA, a 2.5 L tank and a five-year warranty are on the sheet.
- Same 472 × 319 × 237 mm shell as the 10 L, so it is not a bigger object for the extra class.
Limits worth knowing
- Still a 5 °C floor; compressor physics do not change at 12 L.
- No timer or app on Arete One — Arete Two 12 L exists for that.
- Tank still has no handle, per Meaco.
Head to head
- MeacoDry Arete One 12L vs Pro Breeze OmniDry 12L
Two 12 litre compressors for heated UK flats. Arete One publishes a temperature table, HEPA and a five-year warranty. OmniDry sells the same litre class for less, with a 2 L tank and a hose in the box.
