Soucie Salo offers both qualitative and quantitative respiratory fit testing, performed by certified technicians either in-house (in our dedicated fit test room) or on-site at your location.

Qualitative Fit Testing (QLFT)

• Uses a test agent (e.g., Bitrex or saccharin) to detect leaks based on the wearer’s taste or smell response.
• Ideal for half-mask respirators like N95s.
• A simple pass/fail method that meets CSA standards.

Quantitative Fit Testing (QNFT)

• Utilizes a PortaCount device to measure actual leakage and provide a numerical fit factor.
• Suitable for all tight-fitting respirators, including full-face masks.
• Offers precise, data-driven results for regulatory compliance.
