These general purpose disposable N95 respirators filter nuisance odors. They are used where odors are present or there is high risk of exposure to airborne particles, including woodworking, demolition, and food manufacturing. N95 respirators filter at least 95% of airborne particles. They are not oil-resistant. These respirators reduce or eliminate nuisance odors, such as organic vapors and acid gas, that are found in demotion work and food manufacturing.
