What are the unique features of masks made of ptfe washable filter membrane?

The special thing about nano masks is that the middle layer is made of a nano membrane with a smaller pore size (100-200 nanometers), which is the N95 cloth mask filter membrane, with a porosity of more than 85% and 1.4 billion micropores per square centimeter. , aperture range 0.02um-1.5um.

PTFE membrane manufacturer specializes in the production of PTFE water-resistant filter membranes. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE membranes; The materials of the products produced are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
