With this new living room air purier you breathe cleaner air. For the best
results, place the living room air purier in a room where you spend most
of your time, e.g. the living room.
Wherever there are people, plants or pets, there are airborne particles that
can affect your well-being, especially if you suffer from allergies. Because of
these particles, the air inside a room may be more polluted than the air in
a large city.
Normally, particles are invisible and odourless. Nevertheless they can affect
your health. The living room air purier reduces the amount of animal
dander and industrial pollutants in the air, and therefore improves the
air quality. It also lters out ultrane particles larger than 20 nanometres,
including bacteria and some viruses. According to publications of the
World Health Organization, the avian and human inuenza viruses and the
Legionella bacterium are larger than 20 nanometres.
Filtration in several stages
The living room air purier has a unique multi-stage ltration system that
ensures the best air quality:
- Stage 1: The pre-lter has been treated with antibacterial substances. It
catches big particles like human hair, pet hair etc.
- Stage 2: The formaldehyde lter (supplied with AC4074) lters out
formaldehyde and other volatile organic compounds (VOCs). In
combination with the HEPA lter, the multi-care lter lters out dust,
pollen and ultrane particles larger than 20 nanometres, including
bacteria and some viruses. According to publications of the World
Health Organization, the avian and human inuenza viruses and
Legionella bacterium are larger than 20 nanometres.
Note: The AC4074 and AC4072 are suitable for both the formaldehyde lter
and the multi-care lter. When you replace the lter present in your type, you
can choose the lter (formaldehyde or multi-care) that suits your needs best.
- Stage 3: The activated carbon lter lters out odours and harmful gases
effectively.
- Stage 4: The high-performance composite HEPA lter with anti-
bacterial coating effectively lters out ne dust and cigarette smoke,
while the antibacterial and anti-mould functions of organic antibacterial
materials lters out germs and mould.
