Understanding Face Fit Testing Methods
Below is a brief overview of the two main Face Fit Testing methods. For more detailed information, please visit our FAQs page. Alternatively, feel free to contact us directly to discuss your requirements - our team is happy to assist.
Qualitative
Qualitative Face Fit Testing (QLFT) is a widely used method suitable for many tight-fitting disposable and half-mask respirators, providing a practical and compliant way to confirm an effective face seal.
This Face Fit method involves the use of an aerosol containing either a bitter-tasting substance (Bitrex) or a sweet-tasting substance (Saccharin).
This solution is sprayed inside a hood (as shown in the image above) over a seven minute period while the wearer performs 7 exercises designed to test the seal of the mask.
If, after completing the 7 exercises (over the span of 7 minutes), the wearer does not detect the test substance, the test is considered a pass, and a suitable mask will be successfully identified for that individual.
The final step in the process is for the candidate to break the seal to demonstrate how well the mask maintains its fit.
Quantitative
Quantitative Face Fit Testing (QNFT) is a more precise method of respiratory face fit testing, utilising a TSI PortaCount™ particle counting device. The device measures the number of particles inside the wearer’s respirator and compares this to ambient particle levels in the surrounding environment.
Quantitative testing is commonly used where a higher level of accuracy is required, such as for full-face respirators, higher-risk environments, or where objective, numerical evidence of fit is needed for compliance or audit purposes.
During the test, the wearer performs seven exercises while walking on a treadmill or using a stepper. After each exercise, the system calculates whether the fit factor is sufficient before progressing to the next exercise.
This real-time calculation provides an objective, highly accurate assessment of the mask’s fit and removes subjectivity from the testing process.
Which Fit Testing Method is Best for You?
Not sure which method you need? We’re happy to advise based on your masks, tasks and work environment.
Full Face Respirators can only be tested using the Quantitative method. For other types of Respiratory Protective Equipment (RPE), the best method will depend on factors like location, availability of power, the suitability of the venue and any time constraints that may apply.
While Qualitative Face Fit Testing can often be quicker and cause less downtime when conducted effectively, it’s always a good idea to discuss with the Fit Tester which method is most suitable for your specific needs.
