What is Bacterial Filtration Efficiency?
Bacterial Filtration Efficiency or BFE is a measurement of a respirator material's resistance to penetration of bacteria. Results are reported as percent efficiency and correlate with the ability of the fabric to resist bacterial penetration. Higher numbers in this test indicate better barrier efficiency.

What is the difference between BFE and PFE?
BFE (bacterial filtration efficiency) measures the ability to prevent bacteria from traveling through the material (measured at 3 microns). PFE (particulate filtration efficiency) measures the ability to prevent sub-micron particulates from traveling through the material.

What is BFE in mask?
BFE is for Bacterial Filtration Efficiency. It means this mask will block particles with 3 micrometers (㎛), and it helps to stop bacteria, pollen, and droplet. PFE is for Particle Filtration Efficiency.
