Quantitative mask fit testing can be done for any respirator or mask but is mandatory of masks with a fit factor greater than 100. Quantitative fit testing is ideal for candidates who do not taste the sensitivity solution used in a qualitative fit test, who are allergic, claustrophobic or who want a less subjective, more controlled test. This test uses sensors instead of taste to compare room air to the air inside the respirator to give you a very accurate measurement of your mask fit. Meets CSA Standard Z94.4-11 for the selection, use, and care of respirators.  

Clean-shaven where the respirator seals against your face, as per CSA Standard Z94.4-11
