Function and use
The filtration efficiency of kn95 grade masks for particles with an aerodynamic diameter ≥0.3µm is above 95%. The aerodynamic diameter of airborne bacteria and fungal spores mainly varies between 0.7-10µm, which is also within its protection range.Therefore, this type of mask can be used for respiratory protection of certain particulate matter, such as grinding, cleaning and processing of dust generated by minerals, flour and certain other materials.
