The 3M™ rugged comfort quick latch 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 combines comfort, durability and stability with a firm, lightly textured silicone faceseal and strong body construction. The proprietary quick latch design offers an easy, one-hand touch drop-down mechanism for putting the facepiece on and taking it off while moving in and out of contaminated areas. The quick latch also eliminates the need to remove a hardhat or faceshield when lowering or raising the respirator. When properly fitted and used with approved 3M™ cartridges and filters, this respirator helps provide respiratory protection at concentrations up to 10X the Permissible Exposure Limit (PEL). 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. The facepiece offers numerous other comfort features. Two innovative design features have been built-in a special valve cover that helps to direct exhaled breath and moisture downward and 3M™ proprietary Cool Flow™ valve that helps to make breathing easier by reducing heat and moisture. Made to fit securely and comfortably on the head, the facepiece comes with an adjustable head harness assembly featuring long-lasting polyester/spandex straps that stretch and conform to the individual who wears the respirator. This facepiece is compatible with all 3M™ bayonet-style filters and cartridges, including 6000 Series cartridges and 3M™ 2000, 2200, 7000 or 5000 Series filters, to help provide respiratory protection against a variety of gases, vapors and particulate hazards according to NIOSH approvals. This filter compatibility helps to make the respirator highly versatile for many.
