The Hong Kong Polytechnic University commissioned the Taiwan Textile Industry Research Institute (TTIn the test data of RI), the masks meet the first-level standard of ASTM F2100 of the American Society for Testing and Materials in terms of particle filtration efficiency, bacterial filtration efficiency, and virus filtration performance, which is the protection level of medical surgical masks. Even after repeated cleaning 30 times, it is tested by ASTM F2299-03,virusThe filtration performance is still excellent.
Particle filtration effect PFE test reached>98%
BFE test of bacterial filtration effect>98%
Virus filtration effect VFE test also reached>98%
