3. Product features
Powerful disinfection and deodorization
Hydroxyl radicals produce a harmless chemical reaction that creates a unique solution capable of
disinfecting and removing harmful bacteria, viruses, fungi, VOCs, and odor indoors.
Constant level of high air quality
Indoor pollutants are caused by not bringing in enough clean air to dilute emissions from indoor sources
and by not carrying indoor air pollutants out of the area. To remove pollutants, WellisAir Purifier has
developed its device to operate for 24 hours. We recommend using the device for 24 hours to have a
much higher air quality.
Proven technology
This technology is proven to be effective at disinfecting in hospitals and other facilities in South Korea,
China and many other countries.
Easy/inexpensive to use and maintain
Replace the cartridge every three (3) months to ensure continuous high-level air purification.
Power consumption is low. There is no need to buy and change filters or UV lamps.
Error detection system
You will be alerted if the cartridge is not installed properly.
Contamination level sensing
Indoor air quality is displayed with an air contamination sensor (VOCs).
Alarm signal for cartridge replacement
A cartridge replacement signal lights up soon before the cartridge is finished. The device stops
automatically if you miss the alarm signal for replacement.
Additional function
The device can stand by itself or be mounted on the wall.
You can easily hang the device on the wall once it is assembled,
- It can cover 30m2 air purification depending on the extent of pollutants.

3.1 Disinfection and it’s technology
3.2 Test Results
• What are Hydroxyl radicals?
Hydroxyl radicals are produced by sunlight and trapped in the ozone as humid air. These natural substances
are harmless and are easily distinguishable from contaminants.
• How do hydroxyl radicals disinfect?
Tested by KCL (Korea Conformity Laboratories) / 2016. March 24th issued
Hydroxyl radicals surround protection layer
of harmful bacteria or virus
Hydroxyl radicals react with hydrogen
molecules of harmful bacteria or virus layer Converting into H2O
