3MS8511 - 3M 8511 N95 Cool Flow Particulate Respirator, Box of 10

Technical Overview of the 3M 8511 N95 Particulate Respirator

The 3M 8511 N95 Particulate Respirator is a disposable safety face mask designed to provide reliable respiratory protection of at least 95 percent filtration efficiency against certain non-oil based particles. This respirator is engineered for use in industrial environments where workers are exposed to dust, mist, and other particulates during operations such as grinding, sanding, sweeping, sawing, and bagging. It is NIOSH approved (TC-84A-1299) and meets the rigorous standards required for occupational safety in challenging work conditions.

A key technical feature of the 8511 is the 3M™ Cool Flow™ Exhalation Valve. This proprietary one-way valve offers low resistance to exhalation, effectively releasing warm, moist breath from inside the mask. This mechanism prevents the build-up of heat, keeping the wearer cooler and more comfortable, which is critical for compliance during long shifts. The respirator utilizes 3M's Advanced Electrostatic Media (AEM), a technology that uses highly charged microfibers to capture particles while allowing for easier breathing compared to traditional filter media.

Structural integrity and fit are ensured by the adjustable M-Noseclip and braided headbands. The M-Noseclip allows the user to mold the top of the mask to their specific facial contours, reducing the gap where particulates could enter and significantly minimizing the risk of eyewear fogging. The dual-point braided headband design helps provide a secure seal without the discomfort often associated with rubber straps. This product is packaged in a box of 10, ensuring a ready supply for team deployment.
