What is the gas filtration effect of ffp3 mask filter material?

The dust-blocking efficiency of a mask is based on its dust-blocking efficiency against fine dust, especially respirable dust below 5 μm.

The dust-blocking principle of general gauze masks is mechanical filtration, that is, when dust hits the gauze, it passes through layers of barriers to block some large particles of dust in the gauze.

ffp3 mask filter material is prepared using unique biaxial stretching technology, which can ensure complete retention of bacteria and other impurities while having a large flux.

The material is resistant to high temperatures, strong acids and alkali, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
