Half Facepiece, 3M, 6503 Reusable Respirator,

The 3M™ Rugged Comfort Half Facepiece Reusable Respirator 6500 Series helps provide respiratory protection in harsh, dirty environments against airborne contaminants when used with approved 3M™ Cartridges and Filters. This facepiece is designed to help promote comfort, durability and stability with a firm, lightly textured silicone face seal, and strong body construction. While being the lightest silicone 3M™ Facepiece, it is still rugged enough to withstand long hours and extreme conditions. The resilient silicone faceseal offers an extended facepiece life, even keeping its shape in high-heat environments. When properly fitted and used with approved cartridges and filters, this respirator helps provide respiratory protection at concentrations up to 10 times the Permissible Exposure Limit (PEL).
