¹Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
²We challenged our purifier with airborne influenza A (H1N1 virus) at an independent lab. After 60 minutes in the chamber, at maximum fan speed, the airborne virus was reduced by 99%. Real-life efficacy may vary.
³Compared to Dyson Pure Cool purifying fan. Projects 290 L/s of air maximum setting. Tested for air projection (DTM801), purification coverage in a 81m3 room (TM-003711).
⁴Based on 12 hours use per day. Filter life varies according to pollution levels.
⁵At maximum flow rate in Purifier mode.
