3D FIT Sizing is not a fit test.
3D FIT Respirator Sizing is not a respiratory protection fit test. Sizing measures your face and recommends a respirator size.
Fit testing is a regulated procedure under U.S. occupational safety standards (and other regulatory authorities outside the U.S.), designed to evaluate the fit between a specific respirator and an individual's face. This process is required to be conducted annually in the workplace to ensure proper fit and compliance with applicable regulations.
3D FIT Sizing uses US CDC/NIOSH bivariate measurements indicated in numerous peer-reviewed and published studies.
We recommend that the user be completely clean shaven.
When 3D FIT is ready to launch, it will be available in your favorite app store.
We have two US patents granted and one pending. We also have others patents pending around the world.
