3M Disposable Respirator, Universal, NIOSH Rating N95, ASTM Splash Rating Not Rated

These general purpose disposable N95 respirators have an exhalation valve and are used where there is high risk of exposure to airborne particles, including woodworking, demolition, and food manufacturing. N95 respirators filter at least 95% of airborne particles. They are not oil-resistant. 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.
