The 3M™ Odor/Particulate Cartridge 60921 combines a NIOSH-approved organic vapor cartridge with a P100 particulate filter in one unit. It provides at least 99.97% filtration efficiency against oil and non-oil based aerosols as well as NIOSH-approved protection against certain organic vapors. Uses a bayonet-style connection compatible with 3M™ 6000, 6500, and 7500 series facepieces. Sold as a 1-pair (2 cartridge/filter units) pack. Designed for painting, coating, solvent handling, and pesticide application where both vapor and particle protection are required in a single assembly. The cartridge label is black (OV) and the filter is magenta (P100).
What does the 3M 60921 protect against?
The 60921 provides dual protection: NIOSH-approved organic vapor protection (the same as the standalone 6001 cartridge) plus P100 particulate filtration at 99.97% efficiency against oil and non-oil based aerosols. It is designed for environments with both vapor and particulate hazards, such as spray painting, staining, varnishing, solvent application, and pesticide spraying. It also provides nuisance odor reduction from organic vapors in DIY and home use contexts.
What is the difference between the 60921 and using a 6001 cartridge with a 2091 filter?
Functionally, both provide OV and P100 protection. The 60921 is an integrated unit where the P100 filter is permanently built into the cartridge housing. The 6001 plus 2091 combination requires attaching the 2091 filter directly to the facepiece bayonet in front of a 6001 cartridge via a stacked arrangement. The 60921 is more convenient and compact; the 6001/2091 combo allows independent replacement of each component.
Which 3M facepieces is the 60921 compatible with?
The 60921 uses a bayonet-style connection and is compatible with 3M™ 6000, 6500, and 7500 series half-facepieces. It also fits 3M™ Multi-Purpose Reusable Respirator 65021 as a direct cartridge replacement. It uses the same bayonet connection as other 6000 series cartridges, so it fits any 3M facepiece that accepts bayonet cartridges.
When should I replace the 60921 combination cartridge?
Replace the 60921 when breathing resistance increases significantly (indicating P100 filter loading), when you detect organic vapor odors through the cartridge (indicating carbon saturation), or on a documented change-out schedule. Because it combines two different filtration media with potentially different service lives, it is generally replaced as one unit rather than replacing components separately.
Can I use the 60921 for mold remediation?
Yes. The P100 rating meets or exceeds requirements for mold remediation, which typically calls for at least N95 protection. The additional OV component provides protection from chemical odors or low-level vapors that may be present during mold cleanup or remediation with biocides. Always follow applicable EPA and OSHA guidance for mold remediation and use a properly fit-tested respirator.
How does the 60921 compare to the 60923?
The 60921 provides OV and P100 protection. The 60923 adds acid gas protection in addition to OV and P100, making it the more comprehensive option. Use the 60923 if you also work with materials that generate acid gases such as bleach, pool chemicals, or acid-based cleaners. For straight painting or solvent work without acid gas hazards, the 60921 is sufficient and typically less expensive.
