Types of Respirators


  • N95 - P100 Filtering Face Piece Respirator
  • Half Face Respirator 
  • Full Face Respirator 


​​​Qualitative Fit Test (QLFT)

A QLFT is a pass/fail fit test which assesses the adequacy of respirator fit based on the individuals response to a test media.  A QLFT may be used for all tight fitting, negative pressure face-pieces which will be used in atmospheres up to 10 times for the OSHA PEL.  As part of conducting the fit test, technicians will train employees as listed below.  QLFT is conducted using 3M™ or Gerson® Fit Test Kits, and the test agent Saccharin Solution Aerosol or Bitrex™ Solution Aerosol.  


Quantitative Fit Test (QNFT)

A QNFT is an assessment of the adequacy of fit by numerically measuring the amount of leakage into the respirator.  A QNFT is required for all negative pressure full-face and half-face respirators that are to be used in atmospheres greater than 10 times the OSHA PEL.  Our standard QNFT method uses an Ambient Aerosol Condensation Nuclei Counter (TSI PORTACOUNT™).  A fit factor of >500 will be considered a pass for full face piece respirators unless you prefer a higher minimum number.  As part of conducting the fit test, technicians will train employees as listed below.
