3M Disposable Respirator: Dual, Adj, Metal Nose Clip, Comfort, White, M Mask Size, 3M, P100, Molded

These general purpose P100 respirators are oil proof and have an exhalation valve. They are used where there is high risk of oil splash and exposure airborne particles, including woodworking, demolition, and food manufacturing. P100 respirators are oil proof and filter at least 99.7% of airborne particles. The exhalation valve opens automatically when the wearer breaths out to allow breath to exit the mask quickly, keeping the wearer cooler and more comfortable. The valve automatically closes when the wearer inhales to ensure all air breathed in is filtered.
