By adjusting the specific concentration of plasma and UVA wavelengths combined photocatalyst , as well as the action time of the two treatment methods, the disinfection effect of 1+1>2 can be achieved: the sterilization effect of using plasma and ultraviolet  in combination is much greater than using 2 times any single method .

We use High-speed Pulsed Surface Discharge to act on the oxygen and water vapor in the air to form a high density “plasma tunnel” trillions ions , when the air pass in this tunnel with microorganisms  VOC, TVOC and odor , a large number of basic chemical bonds are destroyed. The remaining damaged microorganisms and other substances enter the UVA treating unit , during this contact time less than 1 second , all the microorganisms are inactivated then discharged with the air , the remaining reactive oxygen species as ozone , OH. and HO2 will filtered by a special filter , so there will be no impact on the indoor environment and people inside
