Removal of germs, viruses and contaminants from the air

The individual filter levels combined in the device and the effective interaction are decisive for the correct air filter. Criteria are the amount of air in the room, which should be removed from impurities as quickly as possible (high CADR number), with great thoroughness and reliability (number of filter stages), as quietly as possible (low dB number). There are different filter stages (different filter media) for removing the different loads and soiling.
