The 3M™ particulate filter 2097, P100 with nuisance level organic vapor 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 organic vapors that are below the PEL. Nuisance level refers to concentrations not exceeding OSHA PEL or other applicable government exposure limits, whichever is lower. Do not use for respiratory protection against organic vapors or in environments that are immediately dangerous to life or health (IDLH). The 2097 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.
