The higher the documented percentages for a mask, the better protective performance in preventing microbial penetration. ASTM Level 1(low barrier) masks are designed to be used during patient care where low concentrations of spatter, fluid, or aerosols are How to Choose the Proper Masks for COVID 19?Mar 25, 2020 · BFE is bacterial filtration efficiency and PFE is particle filtration efficiency. BFE is required for medical use mask. For corona virus, N95 bfe pfeKN95 or above is better choice. But the class A GB bfe pfeT 32610 is also a choice for daily use, working place or home.

Both the BFE and the PFE of a mask is important. For example, a mask with a BFE rating of 99 percent at 3.0 microns provides less protection than a mask with a PFE of 98 percent at 1.0 micron. Do not be misled by a high BFE bfe pfePFE rating without knowing the particle size upon which it is based. BFE vs. PFE The ReFilter Face MaskMay 07, 2020 · BFE measures the filtration efficiency of a mask using viable (live) particles (bacteria) that vary in size from 1 to 5 microns. What is PFE Particle Filtration Efficiency? PFE measures the filtration efficiency of a mask using nonviable (nonliving) particles that are fixed in size from 0.1 micron to 1 micron.
