Face Mask KN95

In compliance with GB2626 standard requirements, KN type face masks are classified according to their filtering efficiency for non-oily particles. The KN95 face mask refers to a filtration efficiency of over 95% for non-oily particles with size larger than 0.075 microns, but the diameter of the new coronavirus pneumonia virus is about from 0.1 to 0.12 microns. This means wearing a KN95 face mask can effectively prevent the virus penetration.
