Who needs a mask fit test?Health care professionals (nurses, midwives, social workers, physicians, respiratory therapists, PSWs, and others) Students in clinical placements (nursing, medical, dental, and related programs) Employees in health care and long-term care settings Other sectors where respirator use is mandated, including first responders, laboratory staff, and industrial workers
-
What should I do to prepare for my test?Avoid eating, drinking (except water), chewing gum, or smoking at least 15–30 minutes before testing. Arrive clean-shaven — facial hair (e.g., beard, stubble) may interfere with the mask seal. Avoid wearing makeup, especially foundation, powder, or any product on areas where the mask contacts the face (nose, cheeks, chin). These can affect the seal. Remove jewelry or accessories near the face and neck (e.g., large earrings, nose rings, or dangling earrings) as they may interfere with mask fit. Take your regular medications as prescribed, especially for conditions such as high blood pressure, asthma, or diabetes. If unsure, consult your healthcare provider before your appointment. Stay hydrated the day of your appointment but only sip water up to 15 minutes before the test.
