The filtration efficiency of N95/KN95 masks for particles with an aerodynamic diameter of 0.3µm reaches more than 95%. The aerodynamic diameter of airborne bacteria and fungal spores mainly varies between 0.7-10µm, which is also within the protection range of N95 masks. Therefore, N95 masks can be used for respiratory protection of certain particulates, such as dust generated during grinding, cleaning and processing of minerals, flour and certain other materials, and also suitable for liquid or non-oily non-oil produced by spraying.
