Gerson 1840 R95 Particulate Respirator with Valve, Full Gasket, Adjustable Straps (Bag of 5)

The Gerson 1840 R95 Particulate Respirator wit is a NIOSH-approved R95 disposable respirator that filters at least 95% of airborne particles, oil-resistant for one shift. It is a made-in-USA option for dust with light oil mist such as machining coolant, cutting fluid, and lubricant overspray. As a cup with an exhalation valve respirator, it is best where breathing heat is a concern. Sold 5 per pack.

Step changes by hazard: for maximum filtration a 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.
