3M Aura 9332+ FFP3 Valved Respirator Dust Mask

The 3M Aura 9332+ is a disposable FFP3 respirator mask with a Cool Flow Valve, tested and certified to EN 149:2001 + A1:2009. It is designed for people working in dusty or humid environments — grooms, yard staff, farmers and smallholders mucking out, handling bedding, sweeping barns or working around feed and grain dust.

FFP3 is the highest of the three European filtering facepiece classes and protects against harmful dusts, water and oil based mists or aerosols, and biological agents of risk groups 2 and 3 in concentrations of up to 20 x WEL. The mask is intended for single shift use.

Key Features

• 3M Cool Flow Valve — reduces heat build-up inside the mask in hot and humid conditions.
• Sculpted upper panel — follows the contours of the face to help create an effective seal.
• Embossed top panel — helps reduce fogging of glasses and eyewear.
• Chin tab — makes the respirator easier to position and fit.
• Dolomite clogging test passed (D rating) — better breathing resistance through a dusty shift.
• Three-panel flat-fold design — low profile and easy to store before use.
• Best for dusty yard work: mucking out, bedding down, sweeping, handling hay, straw and feed.

Specifications

How to Use

1. Unfold the respirator and pull the top and bottom panels apart to form a cup shape.
2. Hold the mask with the chin tab under your chin and the nose section uppermost.
3. Pull the lower strap over your head and position it below the ears, then the upper strap above the ears.
4. Press the nose section down along both sides of the nose with your fingertips to mould it to the shape of your face.
5. Check the seal by cupping both hands over the respirator and exhaling — adjust if air leaks around the edges.
6. Dispose of the mask at the end of the shift, or sooner if it becomes damaged, soiled or breathing becomes difficult.

FAQ

What does FFP3 mean on this mask?
FFP3 is the highest European filtering facepiece class. It protects against harmful dusts, water and oil based mists or aerosols and biological agents of risk groups 2 and 3 in concentrations of up to 20 x WEL.

What does the Cool Flow Valve do?
The valve reduces heat build-up inside the mask in hot and humid conditions, which makes longer periods of dusty work more comfortable.

Will it fog up my glasses?
The embossed top panel is designed to help reduce eyewear fogging, and the sculpted upper panel follows the contours of the face to improve the seal.

How long can I wear the 3M Aura 9332+?
It is suitable for single shift use only. Dispose of it at the end of the shift, or earlier if it is damaged, soiled or breathing becomes difficult.

Is it suitable for use with a beard?
No respirator can seal properly against facial hair. Stubble or a beard along the seal area will reduce protection, so the mask should be worn against clean-shaven skin.

Is this mask suitable for mucking out and handling hay?
Yes. It is well suited to dusty yard tasks such as mucking out, bedding down, sweeping and handling hay, straw and feed.
