CHOICE Expert Rating View more details.

This overall score is made up of water removal (30%), claimed water removal (20%), energy efficiency (30%) and ease of use (20%).

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.

Recommended View more details.

We recommend dehumidifiers with an overall score of at least 70%.

Status View more details.

This column shows which products have been discontinued and which are still available in shops. Tested models are those that we've tested and that are currently available in shops. In some instances, at the request of members and when products are still available on the second-hand market and via sites like eBay, we also include models that were previously tested but now discontinued.

Tested model
Price View more details.

Recommended or typical retail price.

Running cost per hour in cents View more details.

Calculated from our performance tests and based on electricity cost of 30c/kWh. 

Power cost to remove 10L of water View more details.

Based on the running cost and water extraction rate in our performance testing, and on electricity cost of 30c/kWh. 

Size View more details.

Based on the amount of moisture the dehumidifiers can extract from the air, we've made size categories suitable for different room sizes.

Weight (kg)
Claimed water removal rate (L/day) View more details.

The rate claimed at 30-32°C and 80% relative humidity.

Claimed operating temperature range (°C) View more details.

The range of room temperatures in which the dehumidifier will function.

Number of fan speeds
Country of origin
Air filter View more details.

A filter on the air intake to prevent dust etc getting into the machine, and to help clear the air in the room.

Humidistat View more details.

Allows you to set the humidity level for the room.

Wheels/castors View more details.

Wheels or castors can make it easier to move the dehumidifier from room to room, but many are light enough to just pick up and carry.

Cord storage View more details.

Cord storage allows you to conveniently coil and store the power cord when the dehumidifier is not in use.

Carry handle(s) View more details.

Most models have one or two carrying handles to help with moving them around.
