The use of air purifiers to filter polluted or contaminated air, seems an interesting solution nowadays. Using an extensive experimental approach, a commercial air purifier was tested under real conditions in-situ. The IAQ was measured in two rooms: living room and bedroom for different air change rates of the air volume. Measurements of PM2.5, PM10, relative humidity, air temperature and sound pressure level were made. It was found that the PM2.5 levels are quickly reduced from 20.64 μg/m 3 and decreased to 5.58 μg/m3.The research was also focused on the noise levels measurements and it was noticed that in Silent to Low mode (60 and 150 m 3 /h) the sound pressure levels are under 30 dB. Overall, the use of air purifiers in homes is recommended nowadays.
