What is the filtration efficiency of ptfe composite filter paper?

The filtration efficiency of ptfe composite filter paper 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, PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception (pore size interception method). We are a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production, and sales.

The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
