The 3M™ Particulate Respirator 8511 features the patented 3M™ Cool Flow™ Valve and helps provide comfortable and reliable respiratory protection. It is ideal for hot/dusty work environments that require extended periods of wear.

The 3M™ Disposable Particulate Respirator N95 8511 is designed to help provide workers with reliable respiratory protection against certain non-oil particles. This respirator may help reduce inhalation exposure to certain airborne biological particles (eg, molds, anthrax, Koch's bacillus, etc.), but it does not eliminate the risk of contract an infection or disease. The soft inner material provides increased comfort while the shell design makes for a roomy and durable respirator. Braided headbands and adjustable M-shaped nose clip help provide a custom, secure seal. This respirator contains an exclusive 3M filtering material which is composed of advanced electrostatic microfibers designed to facilitate breathing. Compatible with a variety of eye and hearing protection products. Featuring a 3M™ Cool Flow™ Exhalation Valve, this respirator is ideal for work environments where heat and humidity are present, and extended wear is required. The proprietary valve is designed to quickly exhaust warm, moist exhaled air, helping to prevent unpleasant heat build-up in the mask, a major source of discomfort for respirator users. The effectiveness of the valve in keeping the air cooler and more comfortable has been demonstrated in tests*: the atmosphere inside a respirator fitted with a Cool Flow Valve is on average -13 cooler, 6°C (7.5°F) than a similar unvalved respirator. The 3M™ Cool Flow™ Exhalation Valve in Respirators is therefore an ideal choice for periods of extended wear, especially in hot, humid or physically demanding environments. * Tested in a 3M laboratory. The trial protocol, data generation and results have been reviewed and approved by an expert from the University of Minnesota.
