48 ㎡ room size is base on 2 air changes per hour(ACPH), meaning that it can purify a 48 m² room 2 times per hour(assuming the room has a ceiling height of 2.4 m), room size = pCADR ÷ 2.4 m÷2. pCADR data from CVC Testing Technology Ltd. Report no.: WTS2022-4212.

Room size(up to) is calculated based on 2 air changes per hour(ACPH) and PCADR, meaning that it can purify a room of this size 2 times per hour(assuming the room has a ceiling height of 2.4 m), Room size = PCADR ÷ 2.4 m÷2.

Effective coverage area is calculated according to the Chinese national standard GB/T 18801-2015, assuming the room has a ceiling height of 2.4 m and considering factors such as the outdoor particulate pollutant concentration of 300μg/m³ and the number of air changes in buildings, the standard is more stringent. Effective coverage area=(0.07~0.12)*PCADR.
