How is filtration efficiency measured?
This is measured by comparing particle concentrations before and after filtration, typically done with particle counters. These devices analyze particle size and quantity upstream and downstream of the filter. Filtration efficiency is determined by the ratio of particles upstream to those downstream at the rated size.Nov 9, 2023

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.
