A dehumidifier does not need an app to earn its keep. It needs to suit your room, deal with the moisture you produce and fit into everyday life without becoming another chore.
That is the appeal of the MeacoDry Arete One 20L. The original Arete remains worth considering if you prefer simple controls and would rather put your money towards the appliance than extra connectivity.
This is a research-based review using published specifications and manufacturer documentation. We have not tested this model ourselves.
Why this Meaco has attracted attention
Meaco’s 2023 Red Dot announcement described Arete One as bestselling and specifically discussed the 20L model. That supports its history as a popular product; it does not establish that this is Meaco’s highest-selling individual dehumidifier today. Meaco’s Red Dot announcement
Sales language is useful context. Your own room, laundry routine and budget should make the final decision.

The useful specifications, without the hype
Meaco publishes these figures for the One 20L:
Details | Manufacturer’s published specification |
Extraction at 20°C and 60% relative humidity | 8.5 litres per day |
Power at those conditions | 216W |
Tank | 4.8 litres |
Sound | 38 or 40dB(A), depending on fan speed |
Weight | 15kg |
These are manufacturer figures. The “20L” rating is at 30°C and 80% relative humidity, not guaranteed daily collection in your home. Meaco’s product specifications, manufacturer manual
Your moisture load matters. A flat with occasional washing creates a different job from a family house with several showers and regular indoor drying.
What makes it appealing
The One provides Smart Humidity, Laundry and Night modes. Meaco says Night mode switches off the display lights and sounds, while humidity mode monitors the room automatically. Meaco’s range comparison
For a buyer who wants to switch on an appliance and get on with the day, that is a sensible feature mix.
The larger tank also deserves attention. Emptying a tank is easy; remembering to empty it can be the problem. Think about where you will put the unit and whether carrying its tank to a sink will be comfortable.
The trade-offs you should actually consider
At 15kg, this is an appliance you should plan around if stairs are involved. Wheels help on a level floor; they do not make repeated upstairs trips effortless.
Sound figures also need context. A low fan setting does not mean silence. If you are sensitive to mechanical noise, check the seller’s return terms before committing to a bedroom position.
The One lacks the Two’s app control, adjustable louvre and extra fan speed. That makes the newer model worth comparing if directing air towards laundry or changing settings remotely would improve your routine. Meaco’s One-versus-Two comparison
Do not upgrade solely because the newer name sounds more capable. Buy features you will use.
How much could it cost to run?
Using the published 216W figure and an illustrative electricity rate of 30p/kWh, an hour of continuous running would cost about 6.5p:
0.216kW × 30p = 6.48p.
That is a calculation, not a current tariff quote or a measured daily bill. Power changes with conditions, and humidity-controlled operation may pause the compressor. Use your own tariff and actual running time for a useful estimate.
Our editorial verdict
Shortlist the Arete One 20L if straightforward controls matter more than smart features. Compare the Arete Two if laundry is a regular priority or you want more control over how the appliance runs.
Remember the ownership details too. Arete is advertised with a five-year warranty, and Meaco’s terms require registration and an eligible purchase. Retain your receipt and check the conditions for your location and seller. Meaco warranty terms

Frequently Asked Questions
We have not verified that claim. Meaco has described the Arete family as bestselling and the One 20L as popular; a current individual-model sales ranking was not available in our research.
No. It refers to extraction capacity under stated conditions. The tank is smaller, so capacity and tank size should be compared separately.
Choose around the features you need and the price difference at checkout. The One suits a simple routine; compare the Two if app control and laundry airflow adjustments would be useful.
