Best quiet dehumidifiers for bedrooms

In its favour

• The maker states 38 dB and calls it its quietest and most energy-saving model yet.
• Laundry mode runs for six hours and then switches off, according to the listing.
• Intelligent humidity mode stops at your target level and restarts when humidity rises.

Good to know

• The listing does not give a clear tank capacity, so emptying frequency is unclear.
• At 15 kg it is heavy to lift up and down stairs.

In its favour

• The listing states extraction at cold temperatures as low as 1 °C.
• Auto restart after a power cut and overdry protection are both listed.
• A continuous drainage hose comes in the box, and it weighs only 6 kg.

Good to know

• 7.5 litres a day is modest for a large, very damp cellar.
• Tank size is not clearly stated in the listing.

In its favour

• The humidity sensor turns it off at your setting and on again when humidity rises.
• Automatic restart is listed, so it resumes after a power cut.
• Desiccant extraction down to 1 °C suits cold bedrooms with streaming windows.

Good to know

• 10 litres a day is less than the compressor models in a warm house.
• The 1 m hose is short, so it must sit near a drain point.

In its favour

• Laundry is one of three automated modes that adjust to the room's humidity.
• The listing states 34 dB(A), so it can dry washing in a bedroom quietly.
• Easy roll castors and a handle make it simple to move next to the airer.

Good to know

• Rated for rooms up to 17 m², so it suits a small drying room.
• The 2.5 litre tank may need emptying during a long session.

In its favour

• Condensate can flow out through an external hose for continuous drainage.
• De'Longhi states 37 dB, so it can run overnight in a bedroom with condensation.
• A full tank light and transparent window show when to empty it.

Good to know

• The listing does not describe a general humidistat or auto restart.
• Quoted for rooms up to 45 m³, so it is a single room unit.

In its favour

• The laundry function runs on full power continuously until you change it, per the listing.
• Desiccant extraction down to 1 °C suits a cold utility room or garage.
• A 1 m drainage hose is supplied for long sessions.

Good to know

• No timer is listed, so laundry mode must be switched off by hand.

In its favour

• Zeolite technology keeps absorption steady even at low temperatures, per the listing.
• 34 dB with no compressor, and the maker says it suits night hours.
• A 2.8 litre tank with a level indicator, plus a drain pipe included.

Good to know
