Review the MeacoDry Arete One 20L Dehumidifier Air Purifier, including moisture removal, filtration, laundry mode, noise levels, and key buying factors.
Managing excess indoor humidity can become a regular concern when condensation appears on windows, laundry takes a long time to dry indoors, or damp conditions develop around the house.
The MeacoDry Arete One 20L Dehumidifier Air Purifier combines moisture removal and filtered air circulation in one appliance, making it worth researching if you want one machine capable of handling both jobs.
The unit uses compressor technology and includes humidity controls, two fan speeds, a laundry setting, independent air-purification operation, a 4.8-litre water tank, and drainage support. Meaco currently positions the 20L model for larger homes of up to four bedrooms.
What Does the MeacoDry Arete One 20L Dehumidifier Air Purifier Do?
The appliance primarily removes moisture from indoor air. It can also circulate room air through its filtration system while dehumidifying or operate in a separate air-purification mode.
That combination makes this dehumidifier with air purifier worth examining if you have limited floor space and would rather avoid running two separate appliances.
According to Meaco, the model operates between 5°C and 35°C and provides a variable humidistat covering 40% to 70% relative humidity. It has two fan speeds with published airflow figures of 145 m³/hour on low and 160 m³/hour on high.

These figures come from Meaco’s technical specifications. Actual water extraction and electricity use depend on temperature, relative humidity, operating settings, and conditions inside your home.
Understanding the 20L Extraction Rating
The product name can make it tempting to assume that this 20L dehumidifier consistently extracts 20 litres every 24 hours. In practice, dehumidifier extraction varies considerably according to room conditions.
Meaco publishes several test figures. At 20°C and 60% relative humidity, for instance, it states an extraction rate of 8.5 litres per day at 216 watts. At 20°C and 80% relative humidity, the stated figure rises to 14.02 litres per day.
This data is useful when comparing models because headline capacity alone does not tell you what extraction may look like under typical household conditions.
Air Filtration Adds a Second Function
An included H13 HEPA filter allows the appliance to filter circulating air. Meaco states that filtration can operate during dehumidification and independently when moisture removal is unnecessary. A washable dust filter is included as well, while a charcoal filter is available separately.
The independent purification setting could be useful during periods when indoor humidity is already controlled but you still want filtered air circulation.
Keep expectations realistic, though. Combining purification and dehumidification does not automatically make this appliance a direct substitute for every dedicated air purifier.
If air cleaning is your primary concern, compare filtration design, airflow, replacement-filter costs, and room requirements with dedicated purifiers before buying.
Can It Help With Indoor Laundry?
Laundry mode is included, making the Arete One relevant if you regularly dry clothes indoors. In this setting, the appliance removes moisture released into the surrounding air rather than directly heating your clothing.
That makes it useful to compare with another laundry drying dehumidifier if indoor clothes drying is one of your main reasons for buying.
Room size, temperature, ventilation, the amount of washing, fabric type, and initial moisture levels can all affect drying time. Manufacturer energy-saving statements should therefore be treated as brand claims rather than guaranteed household results.
Noise Levels and Everyday Placement
Meaco publishes operating noise figures of 38 and 40 dB(A), depending on the fan setting. The company markets Arete One as a quiet dehumidifier and states that the product carries Quiet Mark accreditation.
Noise tolerance remains personal. A sound level that feels unobtrusive in a hallway or utility area could still be noticeable in a bedroom at night.
The unit measures 618 mm high, 366 mm wide, and 272 mm deep. At 15 kg, it is not especially light, although built-in castors make movement across suitable indoor flooring easier.
Water Tank or Continuous Drainage?
The 4.8-litre tank works for standard collection, while continuous drainage is available if you have a suitable drainage point.
If you specifically need a continuous drainage dehumidifier, note that Meaco specifies a 12.5 mm garden-hose connection and states that the hose is not included. A compatible pump is sold separately for installations requiring water to travel upward.
Check the planned location and drainage route before buying accessories. Gravity drainage and pumped drainage have different installation requirements.
Arete One 20L vs Arete Two 20L
Buyers researching the Arete One may also encounter the newer Arete Two 20L. The two models share the same published dimensions and both carry five-year warranties, yet their controls and feature sets differ.
| Feature | Arete One 20L | Arete Two 20L |
|---|---|---|
| Motor | AC | DC |
| Fan speeds | 2 | 3 |
| Lowest stated noise | 38 dB(A) | 38 dB(A) |
| Adjustable louvre | No | Yes |
| On/off timer | No | Yes |
| App control | No | Yes |
| Laundry timer options | No | Yes |
| Warranty | 5 years | 5 years |
Meaco lists Arete Two with app compatibility, an adjustable louvre, three fan speeds, timer controls, and several additional display functions. Arete One uses a simpler control setup.
Your choice can therefore depend on how much you value connected controls and added adjustments compared with a simpler feature set.
What Should You Check Before Buying?
Start with your actual humidity problem rather than the capacity number printed on the appliance.
Check the approximate area you need to manage, typical room temperature, severity of condensation, preferred placement, access to drainage, and frequency of indoor laundry drying. You should also account for the 15 kg weight and available floor space.
Running costs deserve attention too. Meaco publishes 216 watts at 20°C and 60% relative humidity. Electricity cost will depend on your tariff, operating conditions, settings, and runtime, so calculate expected costs using your own electricity rate instead of relying solely on a manufacturer’s example.
Common Questions
Does the Arete One 20L work as an air purifier without dehumidifying?
Yes. Meaco states that its independent air-purification mode can operate without active dehumidification.
Does it have Wi-Fi or app control?
No. Meaco’s comparison data lists the Arete One 20L as non-app-enabled. Arete Two 20L adds app compatibility.
Does it have a timer?
The Arete One 20L does not include the on/off timer found on Arete Two 20L, according to Meaco’s current comparison table.
Can you connect a drain hose?
Yes. Continuous drainage is supported using the specified hose connection. The hose and optional pump are separate items.
What size is the water tank?
The published tank capacity is 4.8 litres.
How long is the warranty?
Meaco currently states that Arete One comes with a five-year warranty. Warranty conditions should be checked with the seller or manufacturer before purchase.
Is the Arete One 20L a Practical Match for Your Home?
The strongest reasons to research this model are its combination of moisture control and filtered air circulation, 4.8-litre tank, laundry setting, two fan speeds, independent purification function, drainage capability, and relatively low published noise figures.
Its limitations matter too. There is no app control, adjustable louvre, or on/off timer, features available on the Arete Two 20L. Its 15 kg weight is another factor if you expect to carry the appliance between floors frequently.
