  • What is BFE for mask?B7hTextile Testing Instruments, Testing Equipment Manufacturer
    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.B7hTextile Testing Instruments, Testing Equipment Manufacturer
