Mask Leak/Fit Testers

Mask leak/fit testers (MLFTs) are used to perform fit testing of respirator face pieces to determine the quality of face-to-mask seals. They are used to ensure that respirator seals provide a safe barrier to a contaminated environment for the user, and that each user knows how to properly don the respirator.
