3M™ Particulate Respirator 8511, N95, is a disposable 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 incorporates 3M's proprietary technology with an advanced electrostatically charged microfiber filter designed for ease of breathing.

The 8511 is fitted with a 3M™ Cool Flow™ Valve, designed to increase exhalation breathing comfort. The 3M™ Cool Flow™ Valve helps direct exhaled air downward and allows for easy breathing. When you work in physically demanding environments, a little more exhalation breathing comfort can help make a difference.
