The dust barrier efficiency of Puweixin Tomcat imported from the United States is based on its barrier efficiency to fine dust, especially respiratory dust below 2.5 microns. Because dust with this particle size can directly enter alveoli, it has the greatest impact on human health. Gauze mask, its dustproof principle is mechanical filtration, that is, when dust collides with gauze, some large particles of dust are blocked in emery cloth through layers of barriers. For some fine dust, especially dust smaller than 2.5 microns, it will enter the respiratory system through the mesh of gauze. Dust mask, its filter material is composed of activated carbon fiber felt pad or non-woven fabric, and those inhalable dust smaller than 2.5 microns pass through this filter material.
