Inventor: CHA SUNG KWANG
IPC: A62B18/02
Filed: 2020-03-05
Abstract: The present invention treats gas, bacteria, yellow dust, and others with the contaminant collecting principle of a mask and negative ions. Bacteria, gas, and yellow dust removal of the mask is based on 0.4 ㎛ (in case of Korean filter (KF) 94).
