Mask FAQs

  • What is Bacterial Filtration Efficiency (BFE)?

    • 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.
