3. Setup: Fitting Instructions
Proper fitting is essential for the respirator to provide its intended protection. Follow these steps carefully:
- Step 1: Unfold the Respirator
Unfold the respirator completely and allow the headbands to hang outward on both sides. - Step 2: Position on Face
Position the respirator on your face with the adjustable metal nosepiece facing up. - Step 3: Secure Headbands
Pull the headbands over your head. Place the bottom band below the ears and the top band on the crown of your head. - Step 4: Adjust Nosepiece
Using both hands, press down on the metal nosepiece to form a tight fit around your nose. - Step 5: Perform Seal Check
Cover the respirator with both hands. Inhale and exhale vigorously. If air leaks around the edges, adjust the straps and reshape the nosepiece until a proper seal is formed.

4. Operating: Performing a Seal Check
It is critical to perform a seal check every time you wear the respirator to ensure a proper fit and effective protection.
- Cup both hands around the respirator.
- Inhale and exhale vigorously.
- If air leaks around the respirator's edges, adjust the nosepiece and headbands until the leakage is corrected.
- Once corrected, repeat the seal check again to confirm.
WARNING: This respirator should be used without a proper fit. This respirator helps protect against certain contaminants. It may not eliminate the risk of contracting disease or infection. Misuse may result in sickness or death.

7. Troubleshooting
If you experience issues with your BNX N95 Respirator Mask, consider the following:
- Air Leakage: If air leaks around the edges during a seal check, re-adjust the headbands and reshape the metal nosepiece. Ensure the mask is centered on your face.
- Discomfort: Ensure the headbands are positioned correctly (bottom band below ears, top band on crown of head). The nosepiece should be gently but firmly molded to your nose.
- Breathing Difficulty: If breathing becomes difficult, the respirator may be excessively clogged or damaged. Discard the mask and replace it with a new one.
- Facial Hair: Beards or other facial hair can prevent a proper seal. The respirator should not be used with facial hair that interferes with the seal.
