Filter system:

Nylon prefilter net
The filter net set in a plastic frame represents the first barrier for particles. Large particles
in the room air are caught by this net and can later either be vacuumed off with a vacuum
cleaner or washed off under running water.
1 prefilter (1)
This pre-filter is a coarse particle filter which collects the larger particles from the air flowing
through it. This process additionally protects the HEPA filter element from these particles
and thus increases the service life of the following filter elements.
2 HEPA filters (2)
In order to remove even the smallest particles, the room air flows through a HEPA filter in
the second step of the cleaning process, which absorbs pollen, fine dust and spores among
other things.
3 Activated carbon filter (3)
In the next step, the air now freed of solids is processed by an activated carbon filter. In
this working process odours and toxins are absorbed. Granulated activated carbon is
deliberately used, as it has a high degree of efficiency and a large total surface area.
4 Photocatalytic filter (3)
With the help of this filter odours and bacteria can be fought effectively. Organic compounds are
broken down by means of the photocatalytic effect produced by irradiation with UV light. Oxygen
atoms are attached to organic compounds and gradually broken down into H2O and
CO2.
Ultraviolet light
Besides the activation of the photocatalysis filter, the ultraviolet radiation has a
disinfecting effect. Thus bacteria and viruses are killed by the irradiation with UV light.
Ionizer
In the last step, the air finally flowing out of the device is mixed with a small quantity of
negatively charged ions. These ions attach themselves to the smallest particles in the room
air and charge them statically. The particles charged in this way then tend to accumulate with
other particles and form larger clusters, which can then be more easily absorbed by the filter
medium.
