1. Usage Instructions:
1. This product complies with the national standard GB2890-2009. Please read this manual carefully before use and understand all its contents.
2. Place the mask headband on top of the head.
3. Hold the end of the band with both hands and pull it taut so that the mask fully covers the nose and mouth area. Attach the clasp at the back of the neck to ensure a tight seal around the face.

5. Before use, check the mask to ensure it is properly sealed. Place the palm over the air intake side of the filter box and inhale gently for 5–10 seconds.
