3M 8511 N95 Disposable Respirator with Cool Flow Valve

WC Safety editorial note — 3M 8511 N95 Disposable Respirator with Cool Flow Valve
NIOSH-certified 3M disposable respirator — full specs, compatibility, FAQ, and ordering below. Read our independent review → or see the Disposable Respirator Complete Guide.

The 3M 8511 N95 Disposable Respirator with Coo is a NIOSH-approved N95 disposable respirator that filters at least 95% of non-oil airborne particles. It is the industry-standard choice for general construction dust, sanding, drywall, wildfire smoke, and nuisance particulate. As a cup with an exhalation valve respirator, it is best where breathing heat is a concern. Sold multiple per pack.

Step changes by hazard: for non-oil dust an N95 covers most work, R95 adds oil resistance, and P100 gives oil-proof 99.97% filtration. For gases or vapors, no filtering facepiece will do — use a half mask respirator with cartridges.
