The method that assesses respirator fit by measuring the amount of leakage numerically is indeed the quantitative fit test. This approach uses specialized equipment to provide a numerical value regarding the effectiveness of the respirator’s seal around the user's face. During a quantitative fit test, the amount of ambient air that leaks into the respirator is measured, allowing for a clear assessment of the fit quality. This numerical output helps determine if the respirator provides an adequate level of protection based on established fit factors.

In contrast, qualitative fit tests rely on subjective responses to detect leaks, using irritants or taste sensations, which do not provide a numerical value or quantifiable measure of leakage. A fit check involves a simpler validation process performed by the user to confirm that the respirator is properly positioned, but it does not measure leakage quantitatively. A comfort check focuses on how the respirator feels on the face rather than providing any data about fit or leakage. Thus, the quantitative fit test stands out as the only method that gives a numerical assessment of respirator fit.
