Different ffp3 category masks use different filter materials.
The filtration effect is related to the particle size of the particles, and is also affected by whether the particles contain oil.
FFP3 category masks are usually classified according to their filtration efficiency and whether they are suitable for filtering oily particles.
Oil-free particulate matter such as dust, water-based mist, paint mist, oil-free smoke (welding smoke), microorganisms, etc.
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.
