What is the protective effect of the kn95 mask filter membrane?

General masks are made of non-woven materials with large fiber diameters (between 1000 nanometers and 5000 nanometers), and the protective effect is obviously weaker than the kn95 mask filter membrane.

This membrane has super acid and alkali resistance. It can roll 98% concentrated sulfuric acid on the polyester fabric to burn a hole, and it will remain unscathed.

It is a high-tech enterprise specializing in the research and development, production and sales of polytetrafluoroethylene microporous membranes. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of Fortune 500 companies in the United States; The products we produce are produced from imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
