  • At 3M we continuously strive to improve comfort and safety in our Personal Protective Equipment (PPE). The new 3M™ Aura™ 9300+ Series is the result of our continuous drive to improve.

    The Aura range is packed with ground-breaking ideas, technologies and materials but it has retained many of the features that helped make the 9300 series hugely popular.


  • Breathe in more freely

    The 3M™ Aura™ respirators feature 3M’s brand new low breathing resistance filter technology; and innovative filter media that helps minimise breathing resistance. This enables high filtering performance with less effort on the part of the wearer, making protection even less intrusive.

    Breathe out more clearly

    Designed to control air release in such a way that it helps with another common issue with respirators: fogging eyewear.


      In the unvalved models (9310A+ and 9320+) when exhaling, the embossed pattern reduces the airflow through the upper panel. The vast majority of the air exists through other panels, leaving less moist air to reach the surface of eyewear from the top panel.

      When coupled with the 3M™ Cool Flow™ Valve (9312A+ and 9322A+) the majority of moist air is released through the valve, leaving less moist air to reach the surface of the eyewear from the top panel, helping to minimise fogging.

  • Fitting Instructions

    Respiratory protection is only effective is the respirator is correctly selected, fitted and worn throughout the time when the wearer is exposed to respiratory contaminants.


    Fitting instructions must be followed each time the respirator is worn. Before fitting respirator, ensure you are clean shaven and hands are clean. See figure 1.



    1. Inspect respirator for damage. If there is no damage continue with fitting instructions. If damaged is found – discard respirator and locate a replacement.

    2. With reverse side up, use the tab to separate top and bottom panels to form a cup shape. Bend slightly at the centre of the nose clip.

    3. Cup respirator in one hand with open side toward the face (nose clip at the top). Take both straps in the other hand, hold respirator under the chin and pull straps over the head.

    4. Position the upper strap across the crown of the head and position the lower strap below the ears. Straps must not be twisted and ensure that chin tab is not folded in.

    5. Using both hands, mould nose clip to the shape of the bridge of the nose, ensuring a close fit and good seal. Do not pinch the nose clip as this will affect the protection levels achieved.

    6. The seal of the respirator on the face should be fit checked (see below Fit Check steps).


  • Fit Check

    A fit check should be undertaken each time the respirator is worn.


    1. Cover the front of the respirator with both hands being careful not to disturb the fit of the respirator.

    2. (a) UNVALVED respirator – EXHALE sharply
        (b) VALVED respirator – INHALE sharply.

    3. If air leaks around the nose, re-adjust the nose clip to eliminate leakage. Repeat step 2.

    4. If leaks at the respirator edges, work the strap back along the sides of the head to eliminate leakage. Repeat step 2 and 3.



    If you CANNOT achieve a proper fit DO NOT enter the hazardous area.
