Home Dehumidifiers

A home dehumidifier helps stop condensation, damp and mould, and dries washing indoors for a fraction of the running cost of a tumble dryer. Sized in litres a day: around 12L for a flat, 20L for a three bedroom house, 25L and up for a larger or damper one.

Our winter picks

Which dehumidifier for winter?

Below about 15°C a compressor dehumidifier slows right down. Desiccant models keep working to 1°C and blow out slightly warm air, so they suit cold rooms, garages and drying laundry. In a heated home, a compressor model costs less to run.

Desiccant: cold rooms, garages and laundry
Compressor: heated living spaces, lowest running cost

Buying guide

What size do you need

Compressor models are usually rated at 30°C and 80% relative humidity (RH), a standard test point for comparing machines, not the conditions in a British home. At 20°C and 60% RH a machine typically collects around half its rating, and less in a cold hallway. As a rough guide, 10 to 12 litres suits a flat, 20 litres a three or four bedroom house, and 25 litres or more a larger or damper house.

Compressor or desiccant

A compressor model condenses water on a cold coil, suits a heated house and typically draws 150 to 300 watts. A desiccant model soaks moisture into a heated absorbent wheel, so it keeps working in a cold garage, loft or boat and warms the room slightly, but draws around twice the power. Its rating is usually taken at a cooler 20°C and 60% RH, so a 7.5 litre desiccant does the work of a compressor model rated much higher.

Laundry drying and running cost

Laundry mode usually runs the machine flat out, ignoring the humidity setting, so put it in a small room with the door shut and the airer close by. Even then a compressor model draws a few hundred watts, against a couple of thousand for a vented or condenser tumble dryer. Day to day, leave the humidistat at around 50 to 55% so it switches itself on and off, use the timer to keep it quiet overnight, and rinse the dust filter every few weeks.
