Respirator Fit Testing

Quantitative FIT Testing (PortaCount Machine)

A Quantitative FIT Test measures the adequacy of a respirator’s fit by numerically measuring the amount of leakage into the respirator.

The PortaCount works by measuring the concentration of microscopic dust particles in the ambient air and then measuring the concentration of those dust particles that leak into the respirator. The ratio of these two concentrations is called the FIT Factor. The filters stop essentially all the particles so anything that gets into the mask must have come through the face seal. A Quantitative FIT Test is not affected by the person’s sense of smell, taste or sensitivity to irritant chemicals.

* Participants must be clean shaven
