Quantitative fit testing (QNFT) confirms a respirator's fit by comparing concentration levels of a substance outside the respirator to the concentration levels of the same substance inside the respirator. Passing a quantitative respirator fit test with a quantitative fit test machine proves that the facepiece is sized correctly and that the person knows how to put it on correctly.
