The 3M™ particulate filter 2091, P100 helps provide respiratory protection against exposure to lead, asbestos, cadmium, arsenic, and MDA. The filter is effective for concentrations up to 10 times the permissible exposure limit (PEL) with half face pieces, or 50 times PEL with quantitatively fit tested full face pieces. This filter helps protect against a wide range of oil and non-oil based particulate contaminants. 3M™'s advanced electret media (AEM) provides a comfortable lightweight, easy breathing combination. The 2091 is commonly used for welding, brazing, torch cutting, metal pouring and soldering. Inventory needs and training requirements of safety equipment are reduced because this filter works for many different applications. The filter is both flame and water-resistant. Industries where this filter is commonly used include agriculture, construction, general manufacturing, pharmaceuticals and primary metals. The filter works with a wide range of face pieces, including 3M™ half and full Facepieces 6000, 7000 and FF-400 series. If used with 3M™ adapter 502, the filter may also be used with 3M™ respirator 5000 series or 3M™ cartridge 6000 Series. The filter is NIOSH (National Institute for occupational safety and Health) approved for environments containing certain oil and non-oil based particles. The filter has been assigned the color code magenta in the NIOSH system. Passing NIOSH's P-series test criteria, the 2091 P100 filter provides at least 99.97 percent filter efficiency against particles. Breathing hazardous particles can pose a risk to your health. NIOSH, a federal government regulatory agency, has tested and approved the 3M™ particulate filter 2091 to help reduce exposure to certain particles.
