ptfe reusable mask filter material

The latest novel coronavirus is becoming more and more serious, and there are a variety of masks on the market. In addition to feeling anxious about not being able to buy masks, people will also have doubts about the protective performance and safety of masks.

So what kind of materials can really effectively block viruses? Here, the editor recommends to everyone masks made of ptfe reusable mask filters.

The reason why the N95 mask is called “N95” is because it is one of the nine types of anti-particulate masks certified by the National Institute for Occupational Safety and Health (NIOSH). The name represents its filtration level: “N” refers to The filter material in the middle of the mask, the N series filter can protect non-oily suspended particles, and should be replaced after cumulative use of more than 8 hours.

And “95” represents the minimum filtration efficiency of 95%.

Certified by the US NIOSH, the filtration efficiency of non-oily particles is ≥95%.

The PTFE reusable mask filter membrane made by mechanically stretching PTFE material can ensure complete retention of impurities such as bacteria and has 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.
