Biological air impurification inside buildings pose risks often underestimated, even apart from SARS-CoV-2!

Effectivity of the Luftklar filter system
- two high grade pre-filters in accordance with ISO ePM1 55% (F7)
- low noise high performance fans
- optional: thermic filter decontamination
- HEPA H14 filter in accordance with EN 1822 with individual test certificate, removes 99.995% of all viruses and bacteria in the air, guaranteed.

The respiratorical intake of virus-full liquid particles is the main infection method of SARS-CoV-2, according to the Robert Koch Institute.
This can for example be created in the form of drop-lets (from sneezing or coughing) or the even smaller aerosols (that are created by breathing or speaking).
Air purifiers with HEPA filters, that clean interior air 2-3 times within an hour, remove exactly these ultra-fine floating particles and prevent them concentrating into a noticeable mass. In this way, not only bacteria, fine dust or spores but also viruses are effectively pulled out of the circulating air!
How doe HEPA filters work?
HEPA filters consist of fine glass fibre mats. As the glass fibres used only measure 1-10 micrometres and the fibres are laid out randomly and chaotically the filter performance is enormously high so that even the smallest particles can be filtered out of the air. In order to achieve the greatest possible surface area the filter mats are arranged in a wave or zig-zag structure.

In this way a proven effectivity exists against:
VIRUSES (among others SARS-CoV-2 or Influenza)
BACTERIA
ALLERGENS (pollen, house dusts, mildew)
FINE DUST
