4 Layers Of Filtration



The Particle Filtration Efficiency (PFE) test evaluates the nonviable particle retention or filtration efficiency of filter media and other filtration devices at sub-micron levels.

This test is performed on face masks and all filter material that allows 1 cubic foot per minute (CFM) flow to pass through it.


The Bacterial Filtration Efficiency (BFE) test is performed on filtration materials and devices that are designed to provide protection against biological aerosols, such as face masks, surgical gowns, caps, and air filters.
