Working Principle

Chemical Effect: Huge amount of negative oxygen ions and free radicals of high energy in plasma can easily has chemical reaction with hazardous material, and kill the microorganism.
Biological Effect: Plasma has sterilization effect via high energy electrons destroying cell wall of bacteria, virus and other microorganisms.
UV effect: UV is generated during the process of turning air to plasma status. Microorganisms absorb high-energy ultraviolet photons and are killed by them.
Negative Ion effect: Negative Ion Generator brings the oxygen negative electricity and produces the negative ion to purifier the air.
