FIELD: water and air purification technology.
SUBSTANCE: invention relates to air treatment devices, for example, air cleaners, air humidifiers and air driers. Disclosed is an air filtration device (100) comprising air filter (101), which comprises first component (102), adapted for air filtration having a moisture level within a first range of humidity levels, and second component (103) adapted for air filtration, having a moisture level within the second range of humidity levels. Device (100) also comprises control system (106), configured to receive measured relative humidity of air and selection of first (102) or second (103) component for air filtration, depending on measured relative humidity of air.
EFFECT: technical result is higher efficiency of air cleaning device due to possibility of its operation in wide range of air humidity levels.
