Respirator Fit Test

Respirators protect workers from breathable hazards, such as environmental and chemical hazards, as well as airborne biohazards, in the workplace. A respirator, and a proper respirator fit test, are critical components of employee respiratory protection from respiratory hazards.

TSI® provides the leading respiratory protection testing solutions to help you make informed, data-driven decisions. Improve the efficiency and effectiveness of your respiratory protection program with TSI solutions that help support your workers' respiratory safety and to comply with regulated standards.

Fit testing evaluates the seal between a respirator and the face, identifying gaps or leaks that put workers at risk. Fit test results confirm if a mask will provide the right level of on-the-job protection needed. When implemented correctly, a respirator fit test can help ensure that respiratory protection levels are achieved through a properly sized and donned respirator. 


Quantitative Respirator Fit Testing. The Highest Level of Protection.

Quantiative fit testing (QNFT) is the most accurate fit testing method - using data to calculate the fit factor. Passing a real-time quantitative respirator fit test proves that the face piece is sized and donned correctly, as well as provides for valuable opportunity for training.

PortaCount® Respirator Fit Testing equipment measures the fit of the respirator while the user simultaneously performs a series of moving, breathing and talking exercises designed to simulate the same movements made in the field. With step-by-step guidance, the instrument walks you through the fit test. Once the fit test is complete, it is easy to generate reports. Choose the industry’s most accurate, fastest and easy to use fit tester to increase your staff’s safety, with software and features to improve your program’s efficiency and productivity from training through regulatory compliance reporting.

Qualitative Fit Testing. Enhance Your Fit Testing Process.

Qualitative fit testing (QLFT) is a inherently subjective (pass/fail) fit test method that has a higher level of variability across users.

Qualitative Respirator Fit Testing (QLFT) with FitPro™ Ultra Fit Test Software helps remove the guesswork from the fit testing process with step-by-step visual guidance on conducting a qualitative respirator fit test. If you’re not doing quantitative fit testing with PortaCount® Respirator Fit Tester, let’s help ensure you’re doing qualitative fit testing consistently and correctly.
