The respiratory impedance of melt-blown alternative material ptfe nano mask cloth is only 60-70pa, while ordinary melt-blown non-woven masks are as high as 120-250pa. In comparison, the breathability of film masks is already very good, but it certainly cannot be compared to Than not wearing a mask.
The wearing comfort of a polytetrafluoroethylene film mask is mainly determined by the air permeability and moisture permeability of the mask.
Thin film masks have higher air permeability due to their material characteristics of high uniform distribution of holes; coupled with the moisture-proof and moisture-permeable characteristics of film materials, they can give users a more comfortable breathing experience.
