What is quantitative fit testing? Taking precision to the next level.
Fit tests are either quantitative or qualitative. A quantitative fit test uses a machine to provide a numeric assessment of how well a respirator fits a particular individual by measuring the actual amount of leakage into the respirator. A qualitative fit test, on the other hand, is a non-numeric pass or fail test that relies on a respirator wearer’s response to whether or not he or she detects the presence of a test substance (e.g., irritant smoke) when wearing a particular respirator.
Full facepiece respirators and half facepiece reusable respirators need to be quantitatively fit tested when used in environments where the contaminant concentration exceeds ten times the permissible exposure limit, or the “Assigned Protection Factor” (APF) calls for a fit factor greater than 100.
ADVANTAGES OF QUANTITATIVE FIT TESTING:
- No protection-factor limit
- Documentation of numerical results
- No chance of employee deception or bluffing
DISADVANTAGES OF QUANTITATIVE FIT TESTING:
- Only one employee may be fit tested at a time
- More costly than qualitative fit testing
What is qualitative fit testing? Fast and economical fit testing.
There are two types of fit tests: qualitative and quantitative. Qualitative fit testing is a pass/fail test method that uses your sense of taste or smell, or your reaction to an irritant in order to detect leakage into the respirator facepiece. The ...

Do Powered Air-Purifying Respirators (PAPRs) Require Fit Testing?
The answer to this question depends on the type of facepiece that the respirator has. Any facepieces that form a tight seal to the wearer’s face, e.g., half-masks and full facepieces, must be fit tested. Loose-fitting PAPRs, in which the hood or ...
What is a respirator fit test?
A respirator fit test is a method used to verify if a particular size and model of a respirator provides an adequate seal on an individual's face. An appropriately fitted respirator is crucial to prevent exposure to hazardous substances in the air, ...
What steps should be followed to properly fit-test a respirator?
Fit-testing is a critical part of ensuring a respirator effectively protects the wearer. Here are the steps for conducting a fit test: Check the Respirator: Examine the respirator for damage and ensure it’s the correct size and model for the wearer. ...
