This Costway 20-25 L/day dehumidifier sits in the popular mid-size sweet spot of the dehumidifier UK market, removing 20 to 25 litres of moisture per day (at 30°C, 80% RH) for homes, offices and basements. It is a sensible everyday choice for a damp lounge, hallway, utility room or cellar where condensation and black mould build up through autumn and winter. The big draw is its generous 6.5 L tank, larger than many rivals at this litreage, so you empty it far less often, while dual drainage lets you fit the included 100 cm pipe for continuous, hands-free running. Two operating modes and two fan speeds cover general damp control and faster drying, and a three-colour indicator light shows the ambient humidity at a glance. At ≤42 dB it is quiet enough to run in living areas, and a dedicated sleep mode plus 24-hour timer make overnight and scheduled use easy. A child lock keeps settings safe around families, and side handles with castors make the 14.5 kg unit simple to move room to room. As a mid-range compressor unit its running cost is only pennies per hour. In the box: the dehumidifier, drainage pipe and instruction manual.

20L/25L Per Day Dehumidifier with 6.5L Water Tank and 24H Timer for Home Basement — FAQs

How many litres per day does this dehumidifier remove?

It extracts between 20 and 25 litres per day at 30°C and 80% RH, which suits damp homes, offices and basements. The 6.5 L tank means fewer trips to empty it than smaller-tank rivals.

Where should I place the Costway dehumidifier?

Position it centrally in the damp room with clear space around the air inlet and outlet, away from walls and curtains. The side handles and castors make it easy to wheel between rooms or down to a basement.

Is it quiet enough to leave on at night?

Yes. At ≤42 dB and with a dedicated sleep mode it is suited to overnight running, and the 24-hour timer lets you schedule it to switch off automatically.

Can it drain continuously?

Yes. As well as the 6.5 L tank, it supports continuous drainage via the included 100 cm pipe, so it can run hands-free for long periods.

What's in the box?

You receive the dehumidifier, a drainage pipe and an instruction manual. A child lock is built in for family safety.
