Dimplex EverDri 20L Dehumidifier Review: price, specs and verdict (2026)

For a large living room, set the humidistat to around 50 to 55% and leave the EverDri running. Once the room reaches that level, the unit stops and restarts as humidity rises, which saves energy compared with running non-stop.

For drying laundry, set a low target humidity, close the door, and use the high fan speed. Use the timer to stop the unit when the load should be dry rather than leaving it running all day.

For damp or mould, place it near the problem wall with clear airflow all round, and keep it running for the first week or two. The comfort light tells you when the air has reached the target.

Because the 3-litre tank is small, an unattended day in a wet room can mean the unit shuts off when the tank is full. Check it morning and evening for the first few days to learn how fast it fills.

For a garage or outbuilding, stay within the 5 to 35°C operating range. Below that, compressor units lose efficiency and may frost up.

Set the humidistat to the level you want and let the machine cycle. For most homes, 45 to 55% is comfortable, and keeping humidity below about 60% helps prevent mould. The comfort light is a quick check: green means you are at the target, blue means the air is still too humid and red means it is too dry.

The washable pre-filter should be rinsed every few weeks, especially in dusty rooms or homes with pets. The carbon filter is separate and helps with musty smells, but it is not a substitute for finding and fixing the source of the damp.

If you are moving the unit between rooms, wait a few minutes before judging its performance in the new spot, and always empty the tank first to avoid spills. The off-centre handles mean it is best moved with two hands rather than one.

In a garage or outbuilding, keep to the 5 to 35°C range and expect lower output in cool conditions. For a space that regularly drops below 5°C, a desiccant dehumidifier is the correct tool.

Dimplex is part of Glen Dimplex, one of the best-known heating and ventilation groups in the UK, and the EverDri range is its domestic dehumidifier line. The 20L model sits above the 14L version, and is the one to look at for a big living room, an open-plan space or a wet garage.

The headline feature is the electronic humidistat: you set a target humidity, and the unit runs until it gets there, then shuts off. A comfort light turns green when the air is at your chosen level, blue when it is too humid and red when it is too dry, which makes it easy to read the room without a separate hygrometer.

One thing to understand is the capacity figure. The 20 litres a day applies at 30°C and 80% relative humidity. At a more typical UK 21°C and 59% RH the rating drops to around 8 litres a day, so judge it against a 12L-class unit in a normal heated room rather than assuming it removes 20 litres daily. This is true of many dehumidifiers, but it is rarely printed this clearly.

It weighs 13.5kg, has a modest 3-litre tank, and draws about 390W. If you want a larger tank and app control, the Pro Breeze 20L OmniDry is the closest alternative; for a British-made option with a longer track record, see the Ebac 2650E.

The EverDri 20EL is 55cm tall and 31cm wide, so it takes up a little more room than a 12L machine, and at 13.5kg it is the heaviest unit you will want to carry up stairs. The airflow is rated at 150 cubic metres an hour, and the operating range of 5 to 35°C covers heated rooms, utility rooms and most garages outside the coldest weeks of winter.

The tank holds 3 litres. For a machine with a headline of 20 litres a day, that is small, and it is the main practical drawback: in a wet room at full output you can fill it in a few hours, at which point the unit shuts off until you empty it. If you can arrange a hose to a drain, that problem goes away.

What the EverDri does well is feedback. The electronic humidistat lets you set a target, the timer lets you schedule it, and the comfort light shows you the result from across the room. Many rivals leave you guessing about what the machine is doing; this one tells you.
