For anyone weighing up a capable compressor unit for wet windows, slow indoor washing and a damp-feeling spare room, this Meaco MeacoDry Arete® One 20L Dehumidifier / Air Purifier review starts with the day-to-day question: will it be easy to live with as well as powerful enough?
Meaco MeacoDry Arete® One 20L Dehumidifier / Air Purifier
Best suited to laundry-heavy homes that need strong extraction, a large tank and a less fussy drying routine
The short answer is yes for many laundry-heavy homes. The Meaco MeacoDry Arete® One 20L Dehumidifier / Air Purifier is a standalone domestic compressor dehumidifier with optional HEPA/charcoal air-purification filtration, a 20 L/day extraction rating, a 4.8 L tank, laundry mode and a continuous drain option. It is not a tiny box-room machine; it is better understood as a main household moisture-control appliance for repeated use.
Pros & Cons
Pros
- 20 L/day compressor extraction gives it the capacity for larger, repeatedly damp rooms.
- 4.8 L tank reduces how often it needs emptying during laundry sessions.
- Continuous drainage makes it sensible for persistent damp areas where a hose route is practical.
- Laundry mode suits households drying washing indoors without a tumble dryer.
Cons
- At 216 W, it rewards targeted routines rather than being left running without thought.
- A compressor design is not the obvious first choice for very cold outbuilding-style spaces.
- The larger 20 L/day brief can be more than a small, occasionally damp bedroom needs.

Why the 20 L/day rating changes the job it is built for
A 20 L/day extraction rating puts this Meaco in the part of the market aimed at more demanding household moisture patterns. That does not mean it will remove 20 litres from every room every day; real collection depends on room temperature, humidity, ventilation, how much moisture is being produced and how often the unit runs. But as a buying signal, 20 L/day tells you this is built for more than the odd misted window.
The sensible use case is a home where moisture comes back repeatedly: indoor washing several times a week, a bathroom that loads the landing with steam, or a larger living area that feels stale when the heating is on and windows stay shut. In those conditions, a higher-capacity compressor unit gives you more headroom than a compact model, especially when you want the machine to bring humidity down without feeling overworked.
The compressor design also shapes the decision. Compressor dehumidifiers are a common fit for normal heated living spaces, bedrooms, halls and utility corners. The stated 5°C – 35°C operating range gives this model breadth, but if the room is frequently very cold, performance expectations should be different from a warm laundry room. A dehumidifier is at its happiest when the setup supports it: a closed door for laundry, enough warmth in the room and a realistic humidity target.
Laundry mode, tank size and the emptying routine
Laundry mode is one of the most important features here because wet washing is a regular moisture source, not a one-off event. Used in a closed room with clothes spread properly on an airer, a dehumidifier can help pull moisture from the air while the washing releases it. The practical gain is not magic; it is repeatability. The same room, the same airer position and the same routine will usually give a more predictable drying setup than moving washing from radiator to radiator.
The 4.8 L tank is a strong companion to that use. A small tank can become irritating during heavy drying sessions because the machine has to stop when it fills. A 4.8 L tank gives more breathing room before emptying, which is helpful if you are running it while cooking, working or getting children to bed. The tank still needs dealing with, of course, but it is less likely to turn every laundry day into a constant check-and-empty loop.
The continuous drain option is the other ownership feature that lifts this model above a simple plug-in appliance. Where a hose route is practical, continuous drainage can make sense for persistent damp areas or regular laundry drying. It will not suit every room layout, and many people will simply use the tank, but the option is valuable because it lets the machine work with the home rather than forcing one fixed routine.
Noise and electricity in normal household use
Meaco lists the noise level at 38 dB. On paper, that is quiet enough to be considered for living spaces where a harsher appliance would become annoying, though any compressor dehumidifier will still be more noticeable in a silent bedroom than in a utility area or hallway. The key is placement. If you want to run it overnight near a bed, your tolerance for low background appliance noise will decide whether that feels calm or intrusive.
The 216 W power input is also worth reading in a practical way. It is not a high-drama figure, but it is still electricity use, so the best ownership pattern is targeted rather than careless. Run it where moisture is being produced, close the room for laundry drying, let the humidistat and mode do the work, then ventilate when it makes sense. The goal is a drier routine, not a machine humming away in the wrong room because nobody has decided what job it is doing.
This is where the Arete One 20L feels especially well matched to households that want fewer fiddly moisture decisions. Its strength is not just capacity; it is the combination of capacity, laundry mode, a large tank and drainage flexibility. That combination makes it easier to build a repeatable routine, which is usually what separates a useful dehumidifier from an appliance that gets moved around in frustration.
The best fit: repeated moisture, not occasional dampness
The clearest fit is a larger home, a busy flat or a household that dries washing indoors often enough for humidity to become part of the weekly rhythm. If you have one small bedroom that only feels damp after a cold night, this may be more machine than you need. If, however, the spare room becomes a drying room for two days at a time, or the hallway glass is wet most mornings, the 20 L/day class makes more sense.
It is also a good match where tank capacity is a genuine quality-of-life issue. A dehumidifier that technically has enough extraction power can still be irritating if it fills quickly and shuts off during the period when you needed it most. The 4.8 L tank does not remove the chore entirely, but it reduces the frequency of intervention compared with smaller tank designs.
The optional HEPA/charcoal air-purification filtration gives this model a broader role than dehumidification alone. It should still be bought first as a dehumidifier, because moisture control is its primary job, but the air-purifier function is a useful extra for people who prefer one appliance in the corner rather than separate machines competing for plug sockets and floor space.
When another type could make more sense
The main reason to look elsewhere is room temperature. A compressor dehumidifier is often the natural choice for heated living areas, but a cold utility space, unheated room or outbuilding-style area can change the calculation. In those conditions, a desiccant model such as the EcoAir DD1 Simple MK3 is a sensible comparison point because desiccant dehumidifiers are commonly chosen for cooler spaces.
The other reason is scale. The Arete One 20L is aimed at larger homes, indoor washing and persistent damp areas with hose drainage. For a very small room with light condensation, the practical benefit of stepping up to this capacity may be less obvious. You would be paying for headroom you may not use, and you would still need to store a larger appliance when the damp spell passes.
Key questions answered
Is the Meaco Arete One 20L good for drying washing indoors?
Yes, its laundry mode, 20 L/day extraction rating and 4.8 L tank make it well suited to indoor laundry routines. The best results will come from using it in a closed room with washing spaced out on an airer, rather than expecting it to dry a whole open-plan area at once.
Can it help with condensation?
It can help reduce the moisture load that contributes to condensation, particularly in rooms where humidity rises from washing, showers or everyday living. It is not a fix for structural damp, leaks or serious mould problems, but it can be a useful part of a healthier moisture-control routine alongside heating, ventilation and source control.
Verdict
Score: 9.1/10
The Meaco MeacoDry Arete® One 20L Dehumidifier / Air Purifier earns its score through three practical strengths: its 20 L/day extraction rating, its 4.8 L tank and the combination of laundry mode with continuous drainage. Those features point to a machine designed for repeated household moisture rather than occasional condensation.
It is easiest to recommend for homes where indoor washing, damp-feeling rooms and morning window moisture are regular irritations. The main trade-off is that its capacity and 216 W power input reward a clear routine; it is better used with purpose than left running vaguely in the background. For the right home, that is a fair exchange for a more dependable drying and damp-control setup.
