What does PFE99 mean

(Summary description)BFE refers to bacterial filtration efficiency, which is mainly used to reflect the ability of masks to filter microbial particles, which can block pollen and fly. PFE99 refers to particle filtration efficiency, which can block viruses such as influenza and SARS. And VFE refers to virus filtration efficiency.

Information

BFE refers to bacterial filtration efficiency, which is mainly used to reflect the ability of masks to filter microbial particles, which can block pollen and fly. PFE99 refers to particle filtration efficiency, which can block viruses such as influenza and SARS. And VFE refers to virus filtration efficiency.

PFE99 prices

If only BFE is marked, it may not be enough. Masks marked with PFE99 are enough to resist SARS and other viruses. Most masks have the values ​​of BFE and PFE99. For example, if the mask can collect BFE, PFE99 and VFE, it is basically the best mask.

In addition, you can also pay attention to whether PFE99 meets the standards of the American Society for Testing and Materials (ASTM). When the mask is printed with ASTM F2100-11 certification, it has been shown that the mask is more guaranteed and can reduce the ability to spread germs. ASTM F2100-11 has 3 levels (Level 1 to 3), the lowest Level 1 requires BFE and PFE filtration rate to be at least 95%, and PFE99 is better.

Through the above introduction and analysis of PFE99, hope it helps you.
