Instructions for Proper Fit of Respirator Masks

Importance of Proper Seal

Respirator masks are effective only with a good seal between the mask edges and your face. Breaking the seal compromises protection.

Brand Consideration

The masks featured in our video are from 3M. If using a different brand, refer to the instructions before application.

Fitting Instructions

Follow these steps each time you wear a mask:

  1. Clean-Shaven Face: Ensure your face is clean-shaven; respirators should not be worn with stubble, beards, or other facial hair beneath the mask area.
  2. Prepare the Mask: With the reverse side up, separate the top and bottom panels using the tabs. Pull the chin and nose panel tabs until the nose clip bends, forming a cup shape. Ensure both panels are fully unfolded.
  3. Position the Mask: Hold the mask with the open side towards your face. For VALVED respirators, hold the sides of the valve to keep the mask in position. For UNVALVED respirators, cup it in one hand.
  4. Secure Straps: Using your other hand, pull each strap over your head. Place the upper strap across the crown of your head and the lower strap below your ears, ensuring they are not twisted.
  5. Adjust Fit: Use the tabs to adjust the top and bottom panels for a comfortable fit. Ensure the panels are not folded and that the tabs lie flat.
  6. Mould Nose Clip: With both hands, mould the nose clip to the shape of your nose for a close fit and good seal.
  7. Check Seal: Cover the front of the respirator with both hands without disturbing the fit. For UNVALVED respirators, exhale sharply; for VALVED respirators, inhale sharply. If air leaks, readjust the nose clip or straps to eliminate leakage.
  8. Final Checks: If you cannot achieve a proper fit, do not enter the hazardous area.


To remove the mask:

  1. Hold and Lift: Hold the corners of the respirator on both sides of your face between your finger and thumb. Lift the respirator away from your face and then upwards until the headbands come away from your head.
  2. Dispose and Wash Hands: Avoid touching the face-piece with your hands as much as possible. Dispose of the respirator immediately in a clinical waste bag and do not reuse. Wash your hands thoroughly.
