According to the GB2626 standard requirements, KN type masks are classified again according to their filtering performance for non-oily particles, and we have become familiar with three types of masks, KN90, KN95, and KN100. The KN95 mask refers to a filtration efficiency of greater than 95% for non-oily particles above 0.075 microns, and the diameter of the new coronavirus pneumonia virus is about 0.1 to 0.12 microns.
