The 3M 5N11 is a NIOSH-approved N95 particulate filter for environments containing certain non-oil-based particles. Its lightweight, low-profile design uses polyester filter material and is compatible with 3M 5000 Series Respirators and 6000 Series gas and vapor cartridges; for use with the listed 3M half- and full-facepiece respirators, it requires a 3M 603 Filter Holder and 3M 501 Retainer. Applications include sanding, spray painting, welding, manufacturing, agriculture, and non-oil pesticide spraying. Each case contains 100 filters.
