Technologies used
Our air purification and sterilization system is made up of 4 filters (pre-filter, activated carbon filter, HEPA H13 filter and photocatalyst module). These have different functions in order to purify and sterilize the air in the most efficient way possible. Indeed, the different succession of filtrations, allows first to purify the air, then to sterilize the air.
Quite simply, the air enters through the pre-filter, then it passes through the activated carbon filter and arrives in the HEPA H13 filter. At this stage the air is purified, then the purified air arrives in front of the photocatalysis device. Once the air has passed through the photocatalysis filter it is sterilized. This is why the final result on air quality is very efficient.
This combination of technology and very precise succession of filters is the subject of a deposit patented by CEVI. CEVI is the research and antiviral convergence department of KRICT (Korea Research Institute of Chemical Technology).

Photocatalysis is a process that destroys viruses, bacteria, molds, spores and oxidants, odors and volatile organic compounds (VOCs) that circulate in the ambient indoor air. It acts under the action of light rays (UV) on the surface of a titanium dioxide (TiO2) catalyst.
It destroys organic and chemical pollutants by transforming them into harmless molecules such as H2O.
How do our filters work?

Certifications
All filters and processes have been tested and validated by independent laboratories before being marketed on the South Korean market (list of laboratories: Table 3).
Please also find in table 1 (AirJoy range) and in table 2 (Uni-Q range) the list of our certifications and patents. And the full reports of these tests are available to you on request.
