3M™ particulate respirator 8511, N95 is a disposable particulate respirator that is designed to help provide reliable respiratory protection of at least 95 percent filtration efficiency against certain non-oil based particles. The respirator is designed for use for particles such as those from grinding, sanding, sweeping, sawing, bagging or other dusty operations. This respirator can also help reduce inhalation exposures to certain airborne biological particles (examples: mold, Bacillus anthracis, Mycobacterium tuberculosis), but cannot eliminate the risk of contracting infection, illness or disease. Soft inner material provides added comfort while the cup shape design makes the respirator spacious and durable. Braided headbands and an adjustable m-noseclip helps provide a custom and secure seal. The respirator incorporates 3M™'s proprietary technology with advanced electrostatically charged microfiber filter media designed for ease of breathing. This respirator is compatible with a variety of protective eyewear and hearing protection. 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.
