With a high-voltage electrostatic field of about 600 V, bacteria and viruses attached to the dust can be completely killed in an instant to prevent colds, infectious diseases and other diseases. The mechanism of sterilization is to destroy four polypeptide chains of bacterial capsid protein and damage RNA.

It can filter dust, smoke and bacteria smaller than cells, and prevent lung disease, lung cancer, liver cancer and other diseases.
