With this new CleanAir System you breathe cleaner air. For the best results,
place the CleanAir System in a room where you spend most of your time,
e.g. the living room or bedroom.
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 CleanAir System reduces the amount of animal dander
and industrial pollutants in the air, and therefore improves the air quality.
It also filters out ultrafine particles larger than 20 nanometres, including
bacteria and some viruses. According to publications of the World Health
Organization, the avian and human influenza viruses and the Legionella
bacterium are larger than 20 nanometres.

Filtration in several stages

The air cleaner has a unique multi-stage filtration system that guarantees
the best air quality:
- Stage 1: The pre-filter has been treated with antibacterial substances. It
catches big particles like human hair, pet hair etc.
- Stage 2: The formaldehyde filter (supplied with AC4074) removes
formaldehyde and other volatile organic compounds (VOCs). In
combination with the HEPA filter, the multi-care filter filters out dust,
pollen and ultrafine particles larger than 20 nanometres, including
bacteria and some viruses. According to publications of the World
Health Organization, the avian and human influenza viruses and
Legionella bacterium are larger than 20 nanometres.
Note: The AC4074 and AC4072 are suitable for both the formaldehyde filter
and the multi-care filter. When you replace the filter present in your type, you
can choose the filter (formaldehyde or multi-care) that suits your needs best.
- Stage 3: The activated carbon filter removes odours and harmful gases
effectively.
- Stage 4: The high-performance composite HEPA filter with anti-
bacterial coating effectively removes fine dust and cigarette smoke,
while the antibacterial and anti-mould functions of organic antibacterial
materials eliminate germs and mould.
