Anyone drying laundry indoors
You want to manage damp in a utility room and need to consider extraction, airflow, noise and how often you’ll need to empty the tank. Les Numériques’ dehumidifier guide covers this use.
Who is this guide for?
Anyone using a cold cellar
Check the actual temperature of the space and the operating range of the exact model. Wood’s describes different models designed for cold spaces.
Anyone with a damp living space
You want to manage condensation without having an overly intrusive appliance in an occupied room. Les Numériques’ dehumidifier guide also covers the needs of smaller rooms.
What to compare
Start with the room’s temperature and size, then choose a water management option that suits your setup. Finally, check that the noise level and maintenance requirements are right for how you plan to use it.
| What matters | What to check | Who it matters most to |
|---|---|---|
| Extraction for laundry | Compare the stated extraction rate and its test conditions with the room’s temperature and size. | If I dry laundry indoors, I want to know whether the appliance is right for my utility room: around 33% of consumers put laundry drying first. |
| Water management | Check the tank capacity and drainage route; confirm whether a pump is built in if the water needs to be lifted. | If I want to empty the tank less often, I first check where the water can drain: around 27% of consumers make ease of drainage their top priority. |
| Cold cellar | Compare the actual temperature of the space with the operating range stated for the exact model. | In a cold cellar, I want to avoid choosing on the basis of a stated capacity alone: around 20% of consumers prioritise low-temperature operation. |
| Noise and maintenance | Check the noise level for each mode, and make sure the tank and filter are easy to access for maintenance. | In an occupied room, I consider noise and routine maintenance: around 20% of consumers prioritise comfort in the room where they use it. |
Mistakes to avoid
-
Confusing daily extraction with tank capacity
Litres extracted per day and the tank’s capacity describe two different things. The stated extraction rate also depends on the test conditions and room temperature.
Compare litres per day, the conditions that apply and the tank capacity separately.
-
Assuming a drainage outlet means there’s a pump
A hose lets water drain along its route, but that doesn’t mean the appliance can pump it up to a higher point. The Wood’s MDX20P is an example of a model with a pump, according to its manufacturer and Les Numériques’ review.
Identify your drainage point and check the manual to see whether the model has a built-in pump.
-
Choosing a model for a cold cellar based only on its stated capacity
Operating ranges vary between models. Wood’s states that the SW20FW works from +2 °C, while Duux says that the Bora becomes less effective as the room gets colder.
Check the cellar’s temperature and the guidance for the specific model you’re considering before comparing capacities.
-
Relying on the appliance to hide a leak or water ingress
A dehumidifier removes moisture from the air, but it won’t fix a leak or a problem with the building. ADEME recommends suitable ventilation, while the QUALITEL association stresses the importance of finding the source of damp.
If the signs persist or you suspect water ingress, get the cause investigated and seek advice from a building professional.
Brands to consider, model by model
Wood’s
The MDX20P is worth considering for a heated utility room where a pump could help with drainage.
- The manufacturer specifies a pump and a 6 l tank for the MDX20P.
- Les Numériques notes that this model’s noise level varies. Wood’s states that the SW20FW works from +2 °C, but this does not apply to all its models.
Comfee
The Aqua Dry 12 is worth considering for a small room or utility room.
- In its review of the Aqua Dry 12, Les Numériques gives a stated extraction rate of 12 l/day, a 2.5 l tank and continuous drainage.
- With a 2.5 l tank, check whether the emptying frequency suits your needs. These specifications apply to the Aqua Dry 12.
De’Longhi
The DEXD216RF is a compressor model with a laundry function and continuous drainage, worth comparing for a room kept at a moderate temperature.
- For this model, De’Longhi states 16 l/24 h at 30 °C and 80% relative humidity, 40 dB(A) and an input power of 285 W.
- These stated figures alone cannot predict extraction, noise or energy consumption in every home.
Duux
The Bora 20L DXDH20 is worth comparing for a room kept at a moderate temperature if its humidistat, app and drainage meet your needs.
- The Bora manual describes a 4 l tank, a drainage hose and app control.
- Duux says that performance drops as the room gets colder and gives around 13–14 °C as the minimum temperature for optimal operation.
H.Koenig
The DSH520 is worth considering if a 5 l tank, continuous drainage and Wi-Fi control would be useful.
- For this model, H.Koenig states 20 l/day, a coverage area of 25 m², a 5 l tank and 43 dB.
- In its review of the DSH520, Les Numériques notes that it is noisy at full power; this observation applies to this model.

Frequently asked questions
Is a dehumidifier enough if damp or mould keeps coming back?
No, not if a leak, water ingress or poor ventilation is causing the problem. Get the cause investigated and contact a building professional if the marks persist: the appliance won’t fix a problem with the building itself.
Where should you place a dehumidifier in a utility room?
Choose a stable position that allows air to circulate and gives you access to the tank and filter, then follow the clearances specified in the model’s manual. Keep sockets and electrical connections away from splashes and water leaks, and avoid makeshift extension leads; Promotelec also provides electrical safety advice for damp homes.
How can you reduce maintenance and manage a dehumidifier’s running costs?
Choose a tank capacity that won’t need emptying more often than you’re comfortable with, then clean the tank and filter as directed in the manual. To compare electricity use, check the stated power and estimate the actual running time: power alone isn’t enough to calculate consumption without knowing how long the appliance runs.
What warranty applies to a new dehumidifier bought from a business in France?
In France, you can make a claim under the legal guarantee of conformity to the professional seller for two years for a new product. The Ministry of the Economy explains that consumers do not have to prove the defect existed on the day of sale; a manufacturer’s commercial warranty is separate and does not replace this legal guarantee.
