Masks can filter viruses, mainly from the key material – ptfe medical mask filter material.
The material is polytetrafluoroethylene, which is made of extremely fine interwoven fibers. The average diameter of the fibers is about 2 μm. The material has been treated with stationary surface to make it electrostatically charged to enhance the adsorption capacity of dust and particulate matter.
?The PTFE medical mask filter material made by mechanically stretching PTFE material can ensure the complete retention of bacteria and other impurities, while having a large flux.
The material is resistant to high temperatures, strong acids and alkalis, and has wide chemical applicability. When used for gas filtration, it can achieve 100% retention of various phages, bacteria and particles above 0.02um.
PTFE microporous membrane has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency air filters.
The manufacturer has a full set of advanced production equipment and technology, as well as an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the product materials produced are all imported raw materials with high uniformity. Stable performance and good breathability.
