Best Dehumidifier with Air Purifier UK (2026)

A dehumidifier with an air purifier dries damp air and filters particles from it in the same machine. The dehumidifier removes moisture, which tackles condensation, damp and mould growth. The filter, usually HEPA, catches dust, pollen, pet dander and some mould spores as air passes through.

It covers two jobs with one unit, which helps in a small home with limited floor space. If you want to understand how the two appliances differ, our guide on dehumidifier vs humidifier vs air purifier explains it.

The air purifier mode helps with dust, pollen and pet hair, and filtering the air can reduce airborne mould spores. It does not remove the moisture that mould grows on, which is the job of the dehumidifier, and it does not clean mould off a wall.

A built-in filter will catch a good share of particles, but a dedicated purifier is designed around air filtration. If severe allergies are your main concern, check the filter specification and room coverage rather than relying on the combined label. If your problem is damp or condensation, a dehumidifier is the right tool and the filter is a useful extra.

Meaco MeacoDry Arete One 12L and 20L have a built-in H13 HEPA air purifier, quiet running and a 5-year parts and labour warranty. The 12L suits a flat or 1-3 bedroom house at 35 dB(A) on its lowest setting; the 20L suits a regular-sized home. See the Arete One 12L and Arete One 20L reviews.

Meaco MeacoDry Arete Two 10L and 20L add Wi-Fi app control, Alexa and Google voice control, three fan speeds and an LCD display. The 10L has a built-in H13 HEPA filter and suits studios and 1-2 bedroom homes; the 20L suits larger houses. See the Arete Two 10L and Arete Two 20L reviews.

Devola DVHA20L is the most complete 2-in-1: a True HEPA filter, UV-C lamp, ionizer and a PM2.5 air-quality sensor, with 20 litres a day and airflow of up to 140 m³/h. It comes with a 1-year warranty, shorter than Meaco's. Read the Devola DVHA20L review.

Ebac 2650E is British-made with an air purification mode, Intelligent Defrost down to 3°C and a smart humidity mode, with a 2-year warranty. Read the Ebac 2650E review.

Room size and capacity. For a flat or a 1-3 bedroom house, the Meaco Arete One 12L or Arete Two 10L are compact options. For a larger home or a heavy damp or laundry load, look at the 20 litre models: the Meaco Arete One 20L, Arete Two 20L and Devola DVHA20L, or the 18 litre Ebac 2650E, rated for homes with up to 4 bedrooms.

Filter type. The Meaco Arete models use an H13 HEPA filter. The Devola DVHA20L adds a True HEPA filter with a UV-C lamp, an ionizer and a PM2.5 sensor that shows air quality on an LED indicator. The Ebac 2650E has an air purification mode, so check its documentation for the filter details.

Noise. The Meaco Arete One 12L is rated at 35 dB(A) on its lowest setting and the Arete Two 10L from 35 dB(A), while the 20 litre Arete models run at 38-40 dB(A) on their lowest settings.

Warranty. Meaco gives 5 years parts and labour on the Arete models, Ebac 2 years and Devola 1 year as standard. A longer warranty matters on an appliance you will run every winter.

Controls. The Arete Two models add Wi-Fi app control with Alexa and Google voice control. The Arete One models do not.

If your only problem is condensation or damp and nobody in the home has allergies, a dehumidifier without a filter will do the same drying job and may cost less. Our best dehumidifier UK comparison covers all types, and best dehumidifier for mould and damp picks models for damp rooms.

A filter only works if it is kept clean. Check your manual for how often to clean or replace the dust filter and the HEPA filter, and factor replacement filters into your yearly costs. A clogged filter reduces airflow, which makes the unit less effective at both drying and cleaning the air.

Place the unit with space around it, away from curtains and walls, so air can move freely. Our guide on where to put a dehumidifier explains the best positions.

Expecting it to remove mould from walls. It filters spores in the air and dries the air, but it will not clean existing mould. Clean visible mould and fix the cause of the moisture.

Choosing it only for the filter. If allergies are your main concern, a dedicated purifier may suit better. Choose a combined unit when you also have a damp or condensation problem.

Undersizing. A 10 litre unit will struggle in a damp, large house. Match capacity to the space and to laundry use.

Forgetting the humidity target. Aim for 40-60% relative humidity. See our guide on how to stop condensation on windows for everyday steps that help.
