12L/Day Dehumidifier — For Damp Bedrooms, Laundry & Condensation

If you wake up to soaking windows and black mould creeping round the frames, this is the size that actually fixes it. A 12L/day compressor dehumidifier pulls real volumes of water out of the air — enough for a damp bedroom, a flat, or a room you dry washing in.

• Removes up to 12 litres a day — genuine capacity, not a mini desktop unit
• Laundry mode — dries indoor washing far faster, which is the single biggest source of damp in most UK homes (a wash load puts around two litres of water into your air)
• Continuous drain option — run it permanently without emptying the tank
• Auto shut-off when the tank is full
• Quiet enough for bedrooms overnight

Is this the right size for you?

Straight answer: a 12L unit suits a 1–3 bedroom home or flat. If you have widespread damp across a larger house, size up to our 16L model. If you only need to keep a wardrobe or ensuite dry, a small desktop unit is plenty and much cheaper — don't overspend here.

And if it's structural: if damp patches appear regardless of ventilation, there's a tide mark up the skirting, or it's worse after heavy rain, that's a building fault. No dehumidifier fixes it. If you rent, that's your landlord's repair — see Shelter or Citizens Advice.
