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.
Black:Carbon Filter
Active charcoal carbon filters are most effective at removing chlorine, particles such as sediment.
Typical particle sizes that can be removed by carbon filters range from 0.5 to 50 micrometres.
