Step up to bigger rooms with this Costway 40L/day portable dehumidifier UK option, sized for open-plan living areas, larger lounges and damp utility spaces up to 50m². It extracts up to 40 litres of moisture a day (at 30°C, 80% RH), and an 85° auto swing spreads dry air evenly rather than drying just one corner. At a quiet 43.5dB it's pleasant to have running while you relax, with a sleep mode for night-time. Power tops out at around 610W, so it costs roughly 16p per hour at 26p/kWh on heavy extraction, dropping as the air dries. Three modes – auto, continuous and sleep – are a touch away, and you can adjust fan speed, timer and swing angle to suit. Dual displays with colour-coded lights make humidity and status easy to read across the room. Drain it your way: empty the 5.5L tank by hand, or run the included 1m hose for continuous drainage. A washable filter keeps maintenance cheap, while built-in wheels and a handle make the 15kg body easy to move between rooms. In the box: the dehumidifier, drain hose and instruction manual. Like all compressor units, it works best in warmer, humid conditions.

Description

This Costway dehumidifier removes up to 40 litres of moisture per day (at 30°C, 80% RH) across a generous 50 m² area, with a 30%-80% humidity setting to suit varying needs. An 85° auto swing distributes air evenly for added comfort.

40L Dehumidifier for Home 50 M2 Portable Dehumidifier with 3 Modes — FAQs

What size room does the 40L Dehumidifier cover?

It's designed for spaces up to 50m², making it a good fit for open-plan living areas, larger lounges and sizeable utility rooms.

How much does the 40L Dehumidifier cost to run per hour?

Power peaks at around 610W, so it costs roughly 16p per hour at 26p/kWh on heavy extraction, and less once the room dries out.

Is the 40L Dehumidifier quiet enough for a bedroom?

At 43.5dB with a sleep mode it's quiet enough for night-time use, though it's most at home in larger living spaces.

What does the 85° auto swing do?

The 85° auto swing moves the airflow up and down so dry air is distributed more evenly across the room rather than concentrated in one spot.

How do I drain it and maintain the filter?

Empty the 5.5L tank manually or connect the included 1m hose for continuous drainage. The filter is washable, so you can rinse and refit it to keep airflow strong.
