3M™ particulate respirator 8577, P95 is a disposable particulate respirator that is designed to help provide reliable respiratory protection of at least 95 % filtration efficiency against certain oil and non-oil based particles. A carbon layer reduces exposure to nuisance levels of organic vapors such as solvents, degreasers and resins. Suggested applications include foundry operations, lab settings, agriculture, petrochemical manufacturing and undercoating where particles and nuisance levels of organic vapors may be present. Braided headbands and an adjustable m-nose clip are designed to help enhance user comfort and increase wearability. The respirator incorporates 3M™ proprietary technology with advanced electrostatically charged micro-fiber filter media designed for ease of breathing. This respirator is compatible with a variety of protective eyewear and hearing protection. Fitted with a 3M™ cool Flow™ exhalation valve, this respirator is ideally suited for work situations involving heat, humidity or long periods of wear. The proprietary 3M™ cool Flow™ valve is designed to release hot, humid exhaled breath quickly, helping to prevent an unpleasant build up of heat inside the facepiece a significant cause of discomfort to respirator wearers. The cool Flow™ valve's efficiency in keeping breathing cool and comfortable has been demonstrated through testing the atmosphere inside a respirator with a cool Flow™ valve is on average 7.5 °F cooler than the similar product without the valve. This makes cool Flow™ valve respirators ideal for long periods of wear, especially where conditions are hot, humid or physically demanding. Testing conducted in a 3M™ laboratory. Testing protocol, data generation and conclusions were reviewed and approved by an expert from the University of Minnesota. The testing performed by 3M™ is not a part of the testing and certification conducted by NIOSH. 3M™ Particulate Respirator, Standard, P95 Filter Class, 95 % Filter Efficiency, Dual Braided Elastic Headstrap, 2-Fixed Strap Suspension, Resists: Oil and Non-Oil Based Particles, 6 in Overall Height, 3 in Overall Width, 2-1/2 in Overall Depth, White
