Fit Testing Fit Testing

Quantitative Fit Testing (QNFT):

Quantitative respiratory fit testing uses an instrument to measure the effectiveness of the respirator seal that is suitable for use on the following filtering facepiece respirator types:

• air purifying
• air supplying, and
• N, R, and P series.

A note on fit testing KN95 masks: We will issue a fit test card and report for KN95 masks tested to pass the CSA protocol. The test report and the card show a fit factor at an acceptable level but not a certificate. 

Quantitative fit testing does not rely on your sense of taste, smell, or irritation in order to detect the leakage.

Instead, the respirator fit testing equipment measures real-time fit while the user simultaneously performs a series of moving, breathing and talking exercises designed to simulate the same movements made in the field.

What you’ll learn during your fittest session:

Our respiratory fit test technicians will also address:

• the proper donning and doffing of the respirator
• how to perform seal checks
• respirator care
• use and maintenance of the respirator
• the defining differences between N, R, and P-Series respirators, and
• the difference between half and full facepiece respirators.

Every participant who successfully completes the fit test is provided with a wallet card indicating the respirator they were fitted with and its size.

Their employer will receive a record of training in the form of a fit test report that they can use for record-keeping purposes.

Note for Fit Testing: Clients must be clean-shaven and bring their own mask to their fit testing appointment.
