The 3M Rugged Comfort Quick Latch Half Facepiece Reusable Respirator 6500 Series helps provide workers with respiratory protection in harsh, dirty work 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 in workplaces at concentrations up to 10 times the Permissible Exposure Limit (PEL). While being the lightest silicone 3M half 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.Innovative design features include a valve cover that helps to direct exhaled breath and moisture downward and 3M?s proprietary Cool Flow Valve that helps to make breathing easier. 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 to help provide respiratory protection against a variety of gases, vapors, and particulate hazards (i.e., dust, paint aerosols, etc.) according to NIOSH approvals. This filter compatibility helps to make the respirator highly versatile for many workplace environments and a variety of jobs where respiratory protection is required.Warning: Respirators help protect against certain airborne contaminants.
