Is the PTFE nano mask filter disposable? How long can it be used?

The ptfe nano mask filter membrane is not disposable and can be used for 2-3 days if it is worn correctly and is not damaged during use.

However, in order to prevent secondary pollution, it is recommended to only use it for 2-3 days.

The PTFE filter membrane produced by Suzhou PTFE filter membrane manufacturer 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 alkali, 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.
