Children’s protective masks need to have a filtration efficiency of more than 95% for non-oily particles at a test flow rate of 85L/min, and at the same time, the respiratory resistance should not be higher than 45Pa at a test flow rate of 45L/min; children’s sanitary masks must have a filtration efficiency of more than 95% for non-oily particles at a test flow rate of 32L/min. The particle filtration efficiency is over 90%, the bacterial aerosol filtration efficiency is over 95%, and the ventilation resistance is less than 30P.

The filtration efficiency of PTFE filter material for children’s masks can reach more than 95% for bacteria and PM2.5 particles in the air. The extremely high porosity and ultra-thin thickness of <5μm make it have better air permeability and low breathing resistance. , comfortable to wear.
