Water removal score
View more details.
We set up our dehumidifiers in a temperature- and humidity-controlled test chamber. For each model, we measure the amount of water removed during three test runs at different temperature/humidity combinations that reflect humid winter climates (between 8°C and 16°C and 65% to 90% relative humidity). For details, see our article on how we test dehumidifiers.
-
Claimed water removal score
View more details.
Each dehumidifier has a claim as to how much water they can extract during a 24 hour period. We work out whether they meet this claim at three different relative humidities and temperatures.
-
Energy efficiency score
View more details.
This is a comparative rating of the model's energy consumption and how much water it extracts. An efficient model will use less energy but extract more water when compared to other models.
-
Ease of use score
View more details.
Our lab testers assess each model for ease of accessing and emptying the water tank, quality of instructions and labels, using the controls, mobility of the unit and ease of cleaning it.
-
Room heating (W)
View more details.
The heating effect from the dehumidification process (measured at 12C and 75% relative humidity). This is generally noticeable but far short of what a typical 2000W or 2400W heater will deliver. See our buying guide for more about this.
-
Power consumption (W)
View more details.
The average power consumption in watts under set ambient conditions.
-
Noise (dB)
View more details.
For comparison, a typical conversation is carried out at about 60dB, while city traffic is measured at around 80dB.
-
Measured tank capacity (to switch-off, L)
View more details.
This is the maximum amount of water, in litres, collected in our test before the machine detected "tank full" and switched off. It's usually close to the claimed tank capacity but may be a little under or over that claim.
