The 3M 6000 Half Mask is a low-maintenance reusable respirator, which meets NIOSH and MSHA standards. This mask comes with the 3M 2091/P100 Particulate Filters (2 sets) which are perfect for shaping or sanding surfboards. Known for its lightweight, soft, comfortable fit, a contouring face piece, and low-profile design that provides good visibility with safety glasses. The mask may be disassembled, cleaned, and reused many times, making it very cost effective. Note: If this mask is to be used for resin work, the 3M 6001 Organic Vapor Cartridges are sold separately.
