What is Respirator Fit Testing?

Fit testing evaluates the seal between a respirator and the face, identifying gaps or leaks. It confirms if a mask provides the necessary protection. Proper fit testing helps to ensure respiratory protection levels are achieved.

Quantitative and Qualitative Fit Testing

Quantitative fit testing (QNFT) is the most accurate method, using data to calculate the fit factor. PortaCount™ equipment measures the fit during exercises, providing step-by-step guidance and easy report generation. Qualitative fit testing (QLFT) is subjective and relies on the user's senses. FitPro™ Ultra Fit Test Software provides visual guidance for consistent and correct testing.
