3M™ Particulate Respirator 8210V is a disposable particulate respirator that helps provide reliable respiratory protection of at least 95 percent filtration efficiency against certain non-oil based particles. This respirator is designed for use for particles such as those from grinding, sanding, sweeping, sawing, bagging, or other dusty operations. 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. Fitted with a 3M™ Cool Flow™ Exhalation Valve, this respirator is 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 and to enhance comfort for respirator wearers.
