Removes aerosols including those containing respiratory virus, from the air which passes through the filter. It also sanitizes the air by removing 99.9% of aerosols from the air that may contain viruses.*
AeraSense is a sensor that accurately identifies fine particles that are even smaller than PM2.5 (including most common indoor airborne allergens). It then processes this information to ensure that the purifier’s settings are at the ideal level for current air conditions, and for continuous re-assurance. Then gives you feedback of real time indoor air quality by showing PM2.5 level.
When in Silent Mode, the Purifier turns down its fan speed and noise level to allow a comfortable night's sleep.
(1)From the air that passes through the filter, it is a theoretical time for one-time cleaning calculated by dividing its CADR 333㎥/h by the room size of 48 ㎥ (assuming the room is 20 ㎡ in floor area and 2.4 m in height).
(2)Microbial Reductio Rate Test conducted at Airmid Health Ltd in a 28.5m³ chamber with airborne influenza A(H1N1). Air purifiers alone don’t protect against COVID-19 but can be part of a protective plan (US EPA).
(3)From the air that passes through the filter, tested with NaCl aerosol by iUTA according to DIN71460-1.
(4)Microbial Reduction Rate Test at external lab, in a test chamber contaminated with avian coronavirus (IBV) aerosols, with Philips HEPA NanoProtect filter.
(5)The recommended service life for the device is based on a theoretical calculation of the average annual regional values of harmful air particles outdoors and daily use of the air purifier for 16 hours in automatic mode.
(6)Tested on the filter media for 1 pass efficiency at 5.33cm/s air flow, by a third party lab./From the air that passes through the filter, tested to JISB 9908-2013
(7)The calculated average sound pressure at 1.5 meter from the device, based on measurements according to IEC 60704. Sound pressure level depends on the room construction, decoration and positioning of device and listener.
