Model: 2096 (pair)The 3M™ Particulate Filter 2096, P100, with Nuisance Level Acid Gas Relief 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 facepieces, or 50 times PEL with quantitatively fit tested full facepieces. This filter helps protect against a wide range of oil and non-oil based particulate contaminants. The filter also offers nuisance level odor relief from acid gases that are below the PEL. Nuisance level refers to concentrations not exceeding OSHA PEL or other applicable government exposure limits, whichever is lower.
