MeacoDry Arete One 12L Dehumidifier / Air Purifier
A whisper-quiet 12L compressor dehumidifier with HEPA purification and laundry mode - a plug-in fix for the condensation and damp that plague rented homes.
Strengths
- Very quiet for a compressor unit at 35-38 dB - reviewers found it inaudible through a closed door
- Low running cost, around 151 W, measured even lower in independent testing
- 2-in-1: includes a medical-grade HEPA filter for air purification
Watch outs
- The headline 12L/day figure is at 30 C / 80% RH; expect roughly 5 L/day in typical UK indoor conditions
- 6-hour laundry mode can be too short for full or heavy loads, needing a second cycle
- 2.5 L tank needs regular emptying in a very damp property unless you rig the drain hose
- Type Compressor (R290 refrigerant)
- Rated extraction Up to 12.18 L/day at 30 C / 80% RH; 5.23 L/day at typical UK indoor conditions (20 C / 60% RH)
- Noise 35 dB (low) / 38 dB (high) - Quiet Mark certified range
- Power consumption 151 W at 20 C / 60% RH

How much water will it actually remove in a UK flat?
Meaco does something almost no other manufacturer in this category does: it publishes the honest number next to the marketing one. The Arete One is rated at 12.18 litres a day at 30 C and 80% relative humidity, the warm-humid test condition the whole industry quotes, and at 5.23 litres a day at 20 C and 60% relative humidity, which is a realistic British living room.
That second figure is the one to plan around, and it reframes the whole category. When a budget rival advertises 12 litres a day with no second number, it is not a better machine; it is the same physics with less disclosure. Roughly five litres a day is what a 12L compressor unit genuinely does in a heated UK room, and five litres of water pulled out of a flat every day is a substantial intervention against condensation.
For renters this matters when sizing. A one or two bedroom flat with condensation on the windows and mould in a corner is comfortably within what this machine handles. Trying to dry out a whole house through closed doors is not, whatever the headline figure suggests.
How quiet is it really?
Meaco rates the Arete One at 35 dB on its low setting and 38 dB on high, and the unit carries Quiet Mark certification, an independent acoustic accreditation awarded to products assessed as unusually quiet for their category. Owner reviews across the range consistently describe it as inaudible from an adjacent room with the door closed, and quiet enough to sleep beside on the low setting.
This is the Arete One's central argument. A dehumidifier that is too loud for a bedroom gets used in the daytime, in the wrong room, or not at all, and an unused dehumidifier removes no water regardless of its rating. The acoustic work is what converts the specification into results.
Night mode goes further by dimming the display and holding the fan low. For a tenant whose condensation problem is worst overnight in a bedroom, which is the usual pattern, being able to run the machine while asleep in the affected room is the whole point.
What does the HEPA filter add?
The Arete One ships with a medical-grade HEPA filter behind the washable dust filter, so the same airflow that is being dried is also being cleaned of fine particulate. In a flat that would otherwise want both a dehumidifier and an air purifier, that removes one appliance, one socket and one filter subscription from the equation.
Set expectations sensibly. A dehumidifier moves air at the rate its drying job requires, not at the rate a dedicated purifier does, so the cleaning effect is a genuine bonus rather than a replacement for a machine like the Levoit Core 300S in a room with a serious dust or pollen problem. Where it earns its keep is damp flats specifically, because the mould spores that come with a moisture problem are exactly the particulate a HEPA element captures.
One practical note that recurs in owner reviews: the filter arrives in plastic wrapping that is easy to overlook, and the setup instructions are not clear about removing it. Check before the first run.
What does laundry mode do, and is six hours enough?
Laundry mode runs the unit at maximum extraction with the fan directed to speed drying, which is what you want when clothes are on an airer indoors. Drying laundry inside is one of the largest single moisture sources in a rented flat, and doing it in a closed room with a dehumidifier running is dramatically better for the property than doing it with the windows shut and nothing running.
The mode times out after six hours. Owner reviews commonly flag this as too short for a full or heavy load, requiring a second cycle to finish the job. It is a real limitation rather than a fatal one, since restarting is a button press, but it is worth knowing before buying if you dry large loads indoors regularly.
Running cost is modest at 151 W under typical conditions, which is roughly comparable to a couple of old-style light bulbs and far less than the tumble dryer the mode is standing in for.
Why does it suit a rented flat?
Nothing is installed. It plugs into a standard socket, the optional 12.5 mm drain hose is a gravity fitting rather than plumbing, and at 10.9 kg it moves between rooms and between properties without difficulty. There is nothing to ask a landlord about and nothing to make good at check-out.
The five-year parts and labour warranty is the part renters undervalue. Appliances bought for a rented flat tend to outlast the tenancy by years and get moved repeatedly, and a warranty that follows the machine through three addresses is worth more than it looks on a spec sheet. It also signals the manufacturer's own expectation of service life, which in a category full of disposable budget units is a meaningful difference.
The Arete One is the machine to buy when noise matters, when the affected room is a bedroom, or when you want the purification and the warranty. When budget is the binding constraint, the Pro Breeze 12L covers the essentials for less. Either way the appliance is only half the answer, and our guide to stopping damp and condensation in a rented flat covers the ventilation and heating habits that do the rest.
