What can the respiratory impedance of PTFE mask filter material reach?

The respiratory impedance of ptfe mask filter material 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 with 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.

?The ptfe materials produced by the manufacturer are all imported raw materials, with a full set of advanced production equipment, an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membrane; imported from the United States It has advanced production and testing instruments to test the quality of PTFE film, and has passed international SGS testing and certification, as well as ISI testing and certification.
