Fine dust, especially dust less than 5 μm, will pass through the mesh of the gauze and enter the respiratory system.
There are some anti-particulate masks for sale on the market. The filter material is composed of fibers charged with permanent static electricity. Respirable dust smaller than 5 μm will be attracted by static electricity and adsorbed in the process of passing through this filter material. On the filter material, it really plays a role in blocking dust.
The ffp3 mask filter material produced has strong hydrophobicity, chemical resistance, waterproofness and low wind resistance, and can achieve high dust removal efficiency. For some extremely fine particles with a diameter of 0.1um-0.3um, The filtration level can reach H13-U16.
