You were right to be sceptical about air purifiers. The industry has spent the last two years proving it.
Run this one in the bedroom for a month, then slide the filter out. Whatever's on it is what you'd have been breathing, night after night. Whether it works stops being a matter of opinion.
We'd rather give you the number that means something. Most brands would print "up to 1,560 sq ft" on this machine. That figure assumes the air gets cleaned once an hour. In a 35 m² bedroom, this does it roughly five times an hour. Same machine, honest maths.
It earns its keep while you sleep. 30 dB on its lowest setting, about the level of a whisper from across the room. It works at the one hour of the day most purifiers get switched off.
A full pound of activated carbon. 450 g of it. That's the layer dealing with cooking, damp and next door's smoke, and the first one most brands cut back on. Very few of them publish the weight of theirs. Ask them.
Three stages you can inspect. A washable pre-filter for hair and dust, HEPA for the fine particles you'll never see, carbon for everything you can smell. Open it after a month and all three will have a story to tell.
Built to still be running in five years. The most common complaint in this category isn't performance. It's a motor that gives up inside twelve months. Five-year warranty, free returns if it isn't right.
For the household where someone wakes up coughing and cleaning harder has stopped working, and for people who'd rather look at the filter than read the marketing.
