With this new living room air purifier you breathe cleaner air. For the best results, place the living room air purifier 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 purifier 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 living room air purifier has a unique multi-stage filtration system that ensures 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) filters out 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 filters out odours and harmful gases effectively.

-- Stage 4:The high-performance composite HEPA filter with anti- bacterial coating effectively filters out fine dust and cigarette smoke, while the antibacterial and anti-mould functions of organic antibacterial materials filters out germs and mould.
