Good to know
Mask fit testing questions.
What is qualitative fit testing?
A controlled sweet or bitter aerosol is used to check whether the respirator forms an effective seal against the wearer’s face.
Can I test with facial hair?
Facial hair or stubble cannot cross the respirator’s sealing surface. Participants must be clean-shaven in the seal area for testing.
What respirators can you test?
We test compatible N95 disposable respirators, half-face reusable respirators and full-face respirators using a qualitative process.
Is the result specific to one mask?
Yes. The fit result applies to the exact respirator make, model and size recorded during the successful test.
