Five filters, in which the SAP51 model (initial, cold catalysis, activated carbon, antibacterial and HEPA) was equipped, ionizer and UV lamp guarantee removal of 99.95% PM2,5 suspended dusts (with a diameter not greater than 2.5 μm), 99.99% bacteria and viruses and 99% volatile organic compounds, e.g. formaldehyde.
The mechanical pre-filter is designed to clean the air of all major solid pollutants, such as dust, hair or animal fur. The use of an activated carbon filter aims to neutralize unpleasant odors and volatile organic compounds. Mounted as the third, cold catalysis filter, it is a modern filter that removes carbon monoxide, hydrogen sulphide, ammonia, benzene, formaldehyde and other harmful volatile organic compounds from the air. The antibacterial filter, as the name suggests, has the task of eliminating bacteria, viruses and mold and preventing their development in the device itself.
In the last stage of filtration, a HEPA filter was used. Its task is to retain the smallest particles of pollution, as well as all unpleasant and harmful odors and volatile compounds. Ionizer is another element of the comprehensive air purification system. In the SAP51 model, the ionization efficiency is very high – 10 × 106 ions per second. Thanks to this solution, the device almost completely eliminates the harmful effects of positive ions emitted by electrical equipment. Positive ions that attract bacteria and viruses as well as airborne fungi, molds and other allergens, lose their properties due to ionization. The air saturated with negative ions causes that all microorganisms fall to the ground and in this way do not reach the lungs of the household members. The last purification stage is the use of a UV lamp which light damages the cell nuclei of microorganisms (bacteria, viruses, fungi). It has a supporting function, ultimately sterilizing the air flow that goes through the device.
