The 3M 2091 filters help provide respiratory protection against exposure to dust, lead, asbestos, arsenic cadmium and MDA. The filters are effective for concentrations up to 10 times the Permissable Exposure Limit (PEL). 2091 filters are commonly used for welding, brazing, torch cutting, sanding and grinding. Industries where these filters are commonly used include agriculture, construction, manufacturing, boat building and building renovation. The filters are extremely light weight & flexible and they fit tight against the mask, all of which makes wearing a mask with them fitted more comfortable. The filter works with a wide range of facepieces, including 3M™ Half and Full Facepieces 6200, 7502 and 6800. Passing NIOSH’s P-series test criteria, the 2091 P100 filter provides at least 99.97 percent filter efficiency against particles.
