Filter system:
Prefilter
The prefilter is the first barrier for particles. Large particles in the room air are collected by this
filter and can later either be vacuumed off with a vacuum cleaner or washed off under running
water.
Cold catalysis filter
The catalytic effect of this filter is also used in normal living environments. Activation by UV
light, high temperatures or pressure is not necessary.
Through the catalytic reaction can reduce the concentration of various gaseous compounds,
such as formaldehyde, benzene and TVOC. The reaction of these gases produces water and
carbon dioxide.
Activated charcoal filter
Activated carbon, thanks to its highly porous structure, has a very large surface area, which
enables it to adsorb a large amount of different odorants and flavors, as well as various VOCs.
HEPA Filter
The HEPA (High Efficiency Particulate Airfilter) medium is able to remove even the smallest
particles from the room air. The filtration is carried out by means of mechanical filtration and
particle filtration by adhesion forces.
The HEPA element is additionally equipped with an antibacterial filter fabric.
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.
Ultraviolet light
Irradiation with ultraviolet light is used for disinfection in many areas of industry and medical
technology. This disinfecting and sterilizing effect is also used to clean the room air flowing
through the air purifier.
Notes on air cleaning for cigarette smoke
Cigarette smoke consists of numerous complex chemical compounds. For the air purifier, it is
essentially divided into solid components of smoke and gaseous components of smoke. The
solid smoke particles are filtered out by the HEPA filter. The gaseous components can be
absorbed by the activated carbon and cold catalysis filters.
•
The device should be placed as close as possible to the smoke source.
•
Depending on how many cigarettes are smoked, the service life of the filter is
shortened.
