1. ActivePure® against viruses and pollutants and 2. Powerful air purifiers with conventional technology

ActivePure® eliminates viruses, bacteria and pollutants directly in the air and on surfaces as soon as they appear in the room
Certified: Remove up to 99.9% of viruses (including COVID-19/Corona SARS-CoV-2) in the room within 3 minutes (and on surfaces!), Scope: inactivation of pathogens in the air and on surfaces, test results and official certificates from renowned laboratories

Conventional air purifiers remove fine dust PM 2.5, house dust, pollen, pollen, bacteria and viruses, aerosols, smoke and cigarette smoke, odours, germs and pathogens, microorganisms, mold spores, animal hair and mites, heavy metals, asbestos, toxic dust, TVOC, formaldehyde, organic connections and much more

The individual filter stages combined in the device and the effective interaction are decisive for the right air filter. Criteria are the amount of air in the room, which should be removed from impurities in the shortest possible time (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 dirt.

Volume flow: The Clean Air Delivery Rate (CADR) describes the volume flow and is considered an important parameter when selecting conventional air purifiers. The CADR is a kind of benchmark comparison value of how quickly the air purifiers can suck in impurities from the air in order to be able to remove them in the device.

CADR air rate in comparison

UV-C against viruses

Conventional air purifiers can use UV-C light to eliminate viruses

UV-C lamps emit light that switches off the genetic material of bacteria and viruses. BestElements air filters of the BE AIR series use all UV-C filter stages, the BE AIR8 even as a UV-C double stage… more

Air purifiers play an increasingly important role when several people come together. Especially at events, meetings or when groups come together in some other way, air filters help to remove air pollution and pathogens from the air and to create clean air. Fine dust, pollen, bacteria, viruses, gases, chemicals and various odors endanger our respiratory tract, which can result in the risk of infection, concentration disorders and a weakening of the immune system.
