3M Aura Particulate Respirator N95 Case of 120 Masks

3M™ Aura™ Particulate Respirator N95 with Cool Flow™ Valve (9211+ / 37193) – Case of 120

The 3M™ Aura™ 9211+ / 37193 is a professional-grade, high-efficiency personal protective respirator engineered to deliver reliable respiratory protection against non-oil-based airborne particulates, dusts, and biological aerosols. Utilizing a specialized three-panel flat-fold matrix and 3M's Advanced Electret Media (AEM), this NIOSH-approved N95 mask achieves at least **95% filtration efficiency** while minimizing inhalation breathing resistance. Supplied as a commercial facility logistics case of 120 individually wrapped respirators, this model features an integrated 3M™ Cool Flow™ Comfort Valve that reduces internal heat accumulation, making it ideal for long manufacturing shifts, hot or humid laboratory environments, and vivarium husbandry maintenance cycles.

Technical Performance & Design

• Proprietary Cool Flow™ Comfort Valve: Outfitted with an advanced exhalation valve that opens 44% easier than previous configurations, allowing 70% more warm, moist air to escape quickly. This prevents uncomfortable internal heat buildup and significantly reduces moisture collection inside the facepiece.
• Advanced Electret Media (AEM): Constructed with charge-infused microfibers that attract and trap airborne particulates via electrostatic forces. This high-technology media allows for a more open fiber structure, reducing breathing resistance so users can inhale with less physical effort.
• Sculpted & Embossed Top Panel: Features a contoured upper profile that aligns closely with the nose and eye orbits, providing a wide field of vision and ample room for safety eyewear. The micro-embossed texture actively directs exhaled air away from the upper frame to prevent glasses or face shields from fogging.
• Three-Panel Flat-Fold Architecture: Designed with an innovative panel layout that accommodates jaw movements during talking or technical calling without shifting out of place. The collapse-resistant structure folds flat, allowing individual units to be easily carried inside uniform pockets prior to donning.

• Dry Chemical and Reagent Handling: Protects technical personnel from inhaling fine particulate dust when scooping, weighing, or mixing dry bulk chemical powders or buffers.
• Grinding, Sanding, and Facility Maintenance: Excellent for general facility engineering tasks such as processing minerals, woodworking, milling, sweeping, or handling dusty drywall substrates.
• High-Turnover Workplace Safety Compliance: Provides procurement teams with a highly trusted, premium respirator supply. The comfortable braided straps and low-heat valve system drive up long-term protocol compliance across workforces.

3M™, Aura™, and Cool Flow™ are commercial trademarks of the 3M Company. SKU 9211+ / 37193 specifies the standard N95 flat-fold version with an exhalation valve. Note: N95 class filters are designed exclusively for solid or non-volatile liquid particulates and do not filter out toxic gases, organic solvent vapors, or oil-based mists (such as lubricants or cutting fluids) which require an R- or P-grade respirator matrix.
