Certifications

N95

The Sodium Chloride Aerosol Challenge (NaCl) – NIOSH Respirator Prequalification test uses a widely accepted method for evaluating particle penetration and air flow resistance properties of a variety of filtration materials.

Respirators must be prequalified before submitting to NIOSH for certification; other materials, such as breathing system filters and face masks, are tested to determine filtration efficiency for marketing. These tests are performed for masks seeking N95 respirator pre-certification.


PFE99

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.

BFE99

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.
