Replacement filter for the supply air duct of the AlphaFreshbox 200 WiFi
To maintain a healthy room climate, the supply air duct filters of the AlphaFreshbox 200 WiFi and its variant with radon sensor in particular should be replaced regularly. The filters remove dust from the supply air and prevent contamination of the ventilation system.
Dimensions 24.3 cm x 16.2 cm x 2 cm
Filter class G4
Class G4 filters according to DIN EN 779 "Particulate air filters for general ventilation systems" are common coarse dust filters for ventilation systems. They clean the air of particles > 10 µm such as hair, (textile) fibres, spores and pollen, dust, fly ash, insects and sand.
G4 filters can NOT be cleaned!
Washing or cleaning with a hoover can damage the fine filter fabric to such an extent that the efficiency of the filter approaches zero. We recommend cleaning these filters very carefully or, ideally, using them only once and replacing them after 6 months at the latest. This way you will maintain a healthy indoor climate.
