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 10 times 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.
