Dehumidifiers

How to choose the right dehumidifier 

The right dehumidifier depends on the size of the space, how damp it is, and whether you want to dry laundry indoors. Healthy indoor humidity sits between 40% and 60%. Above that, you're more likely to see condensation on windows, a musty smell and black mould around frames and corners.

What size dehumidifier do I need? 

Dehumidifiers are rated by how much water they can remove in a day. As a guide:

• Bora 12L: up to 12 litres a day, for spaces up to around 30m², such as a bedroom, home office or small flat.
• Bora Smart 20L: up to 20 litres a day, for spaces up to around 40m², such as a two to three bedroom home or a room with regular condensation.
• Bora Smart 30L: up to 30 litres a day, for spaces up to around 50m², such as larger homes, very damp rooms, basements or drying a lot of laundry.

If you're between two sizes, go for the larger one. It will reach your target humidity faster and then run on a lower setting, which keeps it quieter.

Drying laundry indoors 

Drying clothes on a radiator or airer adds a lot of moisture to a room. All three Bora models have a laundry mode that speeds up drying and removes that moisture at the same time. Put the dehumidifier in a smaller room with the door closed and the clothes spaced out on an airer for the best results. It costs far less to run than a tumble dryer and is gentler on fabrics.

Water tank and continuous drainage

The Bora 12L has a 1.7 litre tank, and the Bora Smart 20L and 30L have a 4 litre tank. All three switch off automatically when the tank is full. For damp spaces like cellars or garages, connect a hose for continuous drainage so you never need to empty the tank.

Noise levels

The Bora Smart 20L and 30L are Quiet Mark certified, running from 36dB in night mode, so they're suitable for bedrooms and living spaces. The Bora 12L runs from 42dB and also has a night mode.

Smart features 

The Bora Smart 20L and 30L connect to the Duux app, so you can check humidity, set schedules and switch modes from your phone. They also work with Amazon Alexa and Google Assistant. The Bora 12L uses a simple touch panel for anyone who doesn't need app control.

Running costs

Duux dehumidifiers use an automatic humidistat. Set your target humidity (between 30% and 80%) and the dehumidifier switches on and off to hold it, rather than running all day. Each model uses 0.9W on standby. The Bora Smart 30L costs around 8p an hour on its highest setting, and much less once the room has dried out.

Where to put your dehumidifier 

For the best results:

• Place it in the dampest room, or centrally in the home or on a landing to treat several rooms.
• Leave at least 20cm of space around the air inlet and outlet.
• Keep windows and doors closed while it runs.
• Move it between rooms as needed. All three models have wheels and a handle.

Filters and care 

Each Bora dehumidifier includes an activated carbon filter that helps reduce odours and smoke. Replace it roughly every 12 months, and clean the dust filter regularly to keep the dehumidifier working efficiently. Replacement filters are available in our dehumidifier range.
