I'm now in the market for air purifiers. Bedroom @ 4M x 4M which would make it 16m² and my downstairs @ 5M x 4M, 20m². The product page said it's good for a room up to 40m² but that would be a overly large room for the size of the device. I think it's a mis-print and that the Amazon page meant 40M³ (cubed)? My downstairs ceiling is 225cm high, so 5M x 4M x 2.25M would make it 45M³.
Otherwise it looks perfect and I would like to get 2 of them for the above mentioned rooms. I like the small size and great aesthetic. I also have a Dyson fan, dehumidifier and a portable a/c unit which I would use depending on what time of the year it is, then run the air purifier most of the year round especially during hayfever season.
Also, what are those grey balls of fluff that accumulate under the bed / behind the bed? Would this air purifier catch those and stop new fluff from forming?
