Before fitting device, ensure hands are clean.

3M™ Aura™ 9300+ 1. With reverse side up and using tab, separate top and bottom panels to form a cup shape.
3M™ Aura™ 9300+ 2. Ensure both panels are fully unfolded.
3M™ Aura™ 9300+ 3. Cup respirator in one hand with open side towards face. Take both straps in other hand. Hold respirator under chin, with nosepiece up, and pull straps over head.
3M™ Aura™ 9300+ 4. Locate the upper strap across the crown of the head and the lower strap below the ears. Straps must not be twisted. Adjust top and bottom panels for a comfortable fit, ensuring panels and tab are not folded in.
3M™ Aura™ 9300+ 5. Using both hands, mould noseclip to the shape of the nose to ensure a close fit and good seal. Pinching the noseclip using only one hand may result in less effective respirator performance.
3M™ Aura™ 9300+ 6. The seal of the respirator on the face should be fitchecked before entering the workplace.


1. Cover the front of the respirator with both hands being careful not to disturb the fit of the respirator
2a. UNVALVED respirator - EXHALE sharply
2b. VALVED respirator - INHALE sharply
3. If air leaks around the nose, re-adjust the noseclip to eliminate leakage. Repeat the above fit check
4. If air leaks at the respirator edges, work the straps back along the sides of the head to eliminate leakage. Repeat the above fit check. If you CANNOT achieve proper fit DO NOT enter the hazardous area. See your supervisor. Users should be fit tested in accordance with national requirements.

For information regarding fit testing procedures, please check our Fit Test video or contact 3M.
