Chemical Effect: Huge amount of negative oxygen ions and free radicals of high energy in plasma can                                           easily haschemical 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.
