  • Selected respirators: Commonly used in the Hospital Authority or any brand certified with FFP2 or 3 or N95 (clients need to prepare those respirators for testing).
  • Test Method: Quantitative fit testing using OSHA fast filtering face Protocol* [1] to measure particle leakage and generate a numerical fit factor, ensuring an adequate respirator seal [2].
  • Results Access: Test results can be accessed online via the TWC N95 Respirator Fit Testing Report System.
