What filtration efficiency can ptfe nano mask cloth achieve?

The filtration efficiency of ptfe nano mask cloth for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks.

The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.

In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception (pore size interception method). The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is more stable and lasting.

It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
