Can ptfe reusable mask filters prevent new pneumonia?

Yes, the surface of the PTFE reusable mask filter membrane is composed of 100~200 nanofibers staggered into holes. After the fiber diameter is reduced to the nanometer level, the surface area increases, the pore size becomes smaller, and the pore volume increases, which can effectively block the PM2.5.

It also has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is laminated on various fabrics and substrates using a special process. material, it can become a new type of filter material.
