SAS Safety 8641 P100 Valved Particulate Respirator — 2-Pack

The SAS Safety 8641 P100 Valved Particulate Re is a NIOSH-approved P100 disposable respirator that filters at least 99.97% of airborne particles, oil-proof. It is a value choice popular in automotive and DIY work for the highest particulate hazards with oil present, such as lead and heavy oil mist. As a cup with an exhalation valve respirator, it is best where breathing heat is a concern. Sold 2 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.
