The middle layer of the nano mask is embedded with ptfe nano mask cloth, which can reach the KN95 mask protection level and has a filtration performance of more than 95% for fine particles with a diameter of 0.3 microns.
The COVID-19 pathogen is spread through droplets, and the diameter of droplet particles is generally about 5 microns. Therefore, masks using nanofiltration materials can filter the virus very effectively.
Haifei Environmental’s mass-produced mask film materials are required to use the highest testing standards when entrusting samples to third-party testing centers for testing.
Multiple test results show that many technical indicators of microporous membrane protective masks far exceed medical protection level standards.
The porosity of ptfe nano mask cloth can reach more than 88% or even higher, and this film has 1.4 billion micropores per square centimeter, with a pore diameter ranging from 0.1um to 0.5um, and has high and low temperature resistance (-200℃-260℃), no aging, no splitting, no discoloration, and strong weather resistance after long-term use.
? is a polytetrafluoroethylene filter membrane manufacturer specializing in R&D, production and sales.
The polytetrafluoroethylene filter membranes we produce are all imported raw materials, with high uniformity, stable performance and good air permeability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
