AC4220/12
Purifies rooms up to 156 m2
600 m3/h clean air rate (CADR)
HEPA & Active Carbon filter
PM2.5 and Gas sensors
Up to 1.5x more powerful than products of its size (1), thanks to its innovative double-fan design. With powerful filtration of 600 m3/h (CADR), it can easily handle large spaces of up to 156m2 (2) and can clean a room of 20m2 in less than 5 minutes (3).
4-layer filtration made of pre-filter, HEPA NanoProtect and double Active Carbon layer captures 99.97% of particles as small as 0.003 microns (4) – smaller than the smallest known virus!
Experience 35% less noise with SilentWings technology (5). Inspired by the silent flight of owls, our fan-blade design ensures purification as quiet as 15 dB(A). Even at maximum speed, it’s quieter than normal conversation. (6)
