Kn95 Respirator Mask is a Chinese standard mask. It is a type of mask with particle filtering efficiency in our country. Kn95 Respirator Mask and N95 mask are actually the same in terms of particle filtration efficiency.
From the perspective of the scope of application, this standard applies to ordinary self-priming filter respiratory protective equipment for the protection of various particulate matter, typically such as masks. Other special environments (such as hypoxic environment, underwater operation, etc.) are not applicable.
From the perspective of the definition of particulate matter, this standard defines various forms of particulate matter, including dust, smoke, fog, and microorganisms, but it does not define the size of particulate matter.
From the point of view of the filter element level, it can be divided into KN for filtering non-oily particles and KP for filtering oily and non-oily particles, and this is the mark, and the N, R/P specified in the CFR 42-84-1995 interpretation guide similar.
