Air purifier for black mould in the bedroom

The bedroom is the worst place for mould spores — you breathe the same air for eight hours straight. Here's how a purifier helps overnight, and the fixes that stop the mould returning.

Why the bedroom matters most

Bedrooms are prone to condensation — warm, moist air from breathing and sleeping meets cold external walls and windows overnight, and black mould often appears in the corners and behind furniture as a result. Because you spend hours breathing that air, reducing the spores in it is one of the highest-value things a purifier can do.

Quiet enough to run all night

A bedroom purifier only helps if you'll leave it on, which comes down to noise. The 5-Fan Luggable runs under 35 dB — quieter than a library — so it clears the room's air several times an hour while you sleep, without disturbing you. At about £2 a year to run, there's no reason to switch it off.

Stop the condensation that feeds it

Filtration handles airborne spores; the mould keeps coming back unless you cut the moisture. Ventilate the room daily, keep furniture a little off external walls so air can circulate, avoid drying clothes on radiators, and consider trickle vents or a dehumidifier if condensation is heavy. Clean existing black mould with a proper mould remover — not just a wipe.

Placement

Put the purifier where air can reach it — a little off the wall, not boxed in behind the bed or wardrobe — and leave it running overnight and through the day. Spore levels rebuild within hours of turning it off.
