Honeywell 7582P100L vs 3M 60921: OV/P100 Cross-Brand Compared
Same OV/P100 Protection. Different Brand Ecosystem. You Cannot Mix Them.
Reviewed by WC Safety Editorial Team — Last updated: May 2026.
Short answer: The Honeywell North 7582P100L and 3M 60921 are functionally equivalent OV/P100 combination cartridges — both NIOSH-approved for organic vapor protection plus 99.97% P100 particulate filtration. The decisive difference is compatibility: 7582P100L fits Honeywell North 7700 and 5500 series facepieces; 3M 60921 fits 3M 6000, 6500, and 7500 series facepieces. These cartridges are not interchangeable across brands.
Brand Lock-In: Once you commit to a facepiece brand, you commit to that brand's cartridge ecosystem. Honeywell North cartridges only fit Honeywell North facepieces; 3M cartridges only fit 3M facepieces. Review the Honeywell North Cartridge Guide and 3M Filter & Cartridge Guide before purchasing either system.
