Meet the OmniDry family: the right dehumidifier for every room

Moisture shows up differently in every home. In a studio flat, it might be steamed-up windows and washing on the radiator. In a family house, it could be a damp back bedroom, a full airer every day and a utility room that never quite feels fresh.

That's why the OmniDry range comes in four sizes: 10L, 12L, 20L and 40L. Each number is how many litres of moisture the dehumidifier can pull from the air in a day. The bigger the number, the bigger the room, or the bigger the damp problem, it's built for.

Below, we walk through each model, what it does best and the kind of home it suits, so you can choose with confidence.

Whichever size you choose, every OmniDry is designed around the same everyday needs.

Laundry mode: every model has a dedicated laundry setting that boosts moisture extraction, helping clothes dry faster indoors without that damp, musty smell.

Low running costs: from as little as 4p an hour for the OmniDry 10L to 8p an hour for the OmniDry 40L, so you can keep damp at bay without worrying about your energy bill.

Each OmniDry has built in sensors that automatically holds your home's humidity at a constant level. You can also use the smart app or voice control, so you can check and adjust them from your phone or with Alexa and Google Home

Easy water management: empty the tank straight into the sink, or set the 10L, 12L or 20L up for continuous drainage and let it run hands-free.

The OmniDry 10L is the smallest dehumidifier in the range, designed for homes where floor space is precious: flats, student rooms and smaller houses.

It removes up to 10 litres of moisture a day, which is plenty for a bedroom, box room or spare room that's prone to condensation. Because it's compact and lightweight, with smooth-gliding castors, it's easy to wheel from the bedroom to the bathroom to the hallway, then tuck into an under-stairs cupboard or utility corner when you don't need it.

It still has a laundry drying mode, a built-in sensor that keeps humidity at a comfortable 40 to 60%, and a 1.7L tank with a continuous drainage option. At as little as 4p an hour, it's also the lowest-cost OmniDry to run.

Best for: flats, student accommodation, bedrooms and small rooms, and anyone who wants moisture control that doesn't take over the space.

Some homes need more than everyday moisture control. Large open-plan spaces, older properties with persistent condensation and rooms where mould keeps coming back all call for a higher extraction rate, and that's where the OmniDry 40L comes in.

It removes up to 40 litres of moisture a day and covers areas up to 50 m² (538 sq ft), so it suits large homes and even commercial spaces. Despite the extra power, it uses less energy (0.33 kWh) than our other models of a similar size, and costs as little as 8p an hour to run.

Its 5.5L tank is the largest in the range, so it can keep working for longer between emptying. One-touch laundry mode speeds up indoor drying, and smart app and voice control let you check and adjust it from anywhere. At up to 52 dBA, about the level of light rainfall, it's louder than the smaller models but still comfortable for everyday use.

Best for: large and open-plan spaces, severe damp and condensation, recurring mould and big family homes.
