3M 37361 Organic Vapor/HEPA Combination Cartridge is a replacement filter cartridge for 3M half and full facepiece respirators. OV/HEPA combination cartridges provide dual protection — organic vapor absorption for solvent vapors and isocyanate components, plus HEPA filtration for paint mist and fine particulates. This is the correct cartridge for automotive painting applications.
- Type: OV/HEPA Combination
- Compatible With: 3M half and full facepiece respirators
- Application: Automotive spray painting, solvent work, isocyanate exposure
- Replace When: Detectable odor breakthrough or end of service life indicator triggers
- Part Number: 37361
Note: Cartridge respirators with OV/HEPA filters are suitable for solvent-based painting but not sufficient for isocyanate-containing 2K clearcoats in production spray environments — a supplied-air or PAPR system is required for those applications per NIOSH guidelines.
