Replacement filter for the supply air duct of the AlphaFreshbox 100 WiFi
To maintain a healthy room climate, the supply air duct filters of the AlphaFreshbox 100 WiFi and its variant with radon sensor should be replaced regularly. The filters remove dust from the supply air and prevent contamination of the ventilation system.
Dimensions 19.3 cm x 15.8 cm x 4.7 cm
Filter class H13
Class H13 filters according to DIN EN 779 "Particulate air filters for general ventilation systems" are common HEPA filters for ventilation systems. They clean the air of particles < 1 µm such as viruses, germs and bacteria, spores and pollen, dust, fly ash, tobacco and metal oxide smoke, soot and oil vapour in the formation stage and radioactive suspended matter.
H13 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 using these filters only once and replacing them after 6 months. This way you will maintain a healthy indoor climate.
