What the 3M 60926 Multi-Gas P100 Cartridge Protects Against

The 60926 pairs a broad multi-gas sorbent with a P100 particulate filter (99.97% of oil and non-oil aerosols, magenta band). Its NIOSH approval spans ten chemical categories: certain organic vapors, chlorine, hydrogen chloride, sulfur dioxide, chlorine dioxide, hydrogen sulfide, ammonia, methylamine, formaldehyde, and hydrogen fluoride. That combined coverage is why it is the go-to cartridge for environments where several gases — or an uncertain mix within its rating — appear alongside dust or mist. On a 3M bayonet facepiece it can be used up to 10 times the PEL on a half mask and 50 times on a quantitatively fit-tested full facepiece.

The trade-off with any broad cartridge is efficiency: a narrower cartridge is lighter, cheaper, and breathes easier, and it often lasts longer against a single contaminant. So reach for the 60926 when your hazard is genuinely mixed or unknown-within-rating, and drop to a matched cartridge when it is not — the 60921 for organic vapor, the 60922 for acid gas, the 60923 for organic vapor plus acid gas, the 60924 for ammonia, or the 60925 for formaldehyde. Our multi-gas cartridge guide maps the choice.

Where It Fits in the 3M 60900 Line

The 60900 series is a ladder of combination cartridges on the same P100 platform, and the 60926 sits at the top for breadth. Below it, each cartridge trades coverage for economy: organic-vapor-only, acid-gas-only, organic-vapor-plus-acid-gas, ammonia, and formaldehyde. Above and beside it, the 60928 adds mercury vapor and chlorine with an end-of-service-life indicator. All of them fit the same 3M 6000, 7000, and FF-400 facepieces, so you can match the cartridge to the hazard without changing masks. If you only need particulate, a filter like the 3M 2091 P100 is the lighter option, and for a broader look at respirator selection start with when do you need a respirator.

Frequently Asked Questions

Exactly which gases and vapors does the 60926 protect against?

NIOSH approves the 60926 against ten chemical categories: certain organic vapors, chlorine, hydrogen chloride, sulfur dioxide, chlorine dioxide, hydrogen sulfide, ammonia, methylamine, formaldehyde, and hydrogen fluoride — plus non-oil and oil particulate at P100 (99.97%). It is the broadest single cartridge in the 3M 60900 line, combining organic vapor, acid gas, ammonia, and formaldehyde coverage in one housing.

Does the 60926 protect against carbon monoxide?

No. No air-purifying cartridge, however broad, filters carbon monoxide — CO passes straight through sorbent media. Carbon monoxide requires a supplied-air respirator or a CO-specific system with monitoring. Never assume a "multi-gas" cartridge covers CO.

How do I choose between the 60926 and a narrower single-gas cartridge?

Match the cartridge to your actual hazard. If you face several gases at once, or an uncertain mix within its rating, the 60926's breadth is the point. But for a single known hazard, a narrower cartridge is lighter, cheaper, breathes easier, and often lasts longer — the 60921 for organic vapor, the 60922 for acid gas, the 60923 for organic vapor plus acid gas, the 60924 for ammonia, or the 60925 for formaldehyde. Buy breadth only when you need it.

What is the difference between the 60926 and the 60928?

Both are broad multi-gas P100 cartridges, but the 60928 adds mercury vapor and chlorine with an end-of-service-life indicator (ESLI) for those, which the 60926 does not have. If mercury vapor is part of your hazard, look at the 60928; for the wide gas mix without mercury, the 60926 is the standard choice.

Does the 60926 protect against hydrogen sulfide?

Hydrogen sulfide is in the 60926's NIOSH-approved list, but H2S is acutely toxic and deadens your sense of smell, so treat it with extra caution: rely on gas monitoring and a strict change schedule, not odor, and confirm the specific H2S provisions and any escape limitations on the approval label before entry. For high H2S or oxygen-uncertain work, consider a supplied-air respirator.

Does formaldehyde or another poor-warning gas change how I use it?

Yes. Several covered gases — formaldehyde among them — have poor warning properties, meaning you can be overexposed before you smell anything, and the cartridge has no end-of-service-life indicator for them. Use a written change schedule based on your exposure rather than waiting for odor or taste, especially where formaldehyde or hydrogen sulfide is present.

Is the 60926 compatible with non-3M masks like Honeywell, MSA, or GVS?

No. The 60926 uses the 3M bayonet connection and fits only 3M 6000, 7000, and FF-400 series facepieces. It is not interchangeable with Honeywell/North, MSA, Moldex, or GVS Elipse masks — mixing brands voids the NIOSH approval and can compromise the seal.

What is the assigned protection factor of the 60926?

Fitted correctly, it can be used up to 10 times the PEL on a half facepiece and up to 50 times on a quantitatively fit-tested full facepiece, for the gases and particulate in its rating. If your measured exposure exceeds those multiples, you need a powered or supplied-air respirator, not this cartridge.

Do I need a fit test with the 60926?

Yes. Any tight-fitting respirator used at work requires an OSHA fit test and a user seal check each time you don it, and it will not seal over facial hair on the sealing surface. A cartridge only performs behind a properly sealed facepiece — a leak lets contaminated air bypass it entirely.

Can I use the 60926 for spraying 2K (isocyanate) automotive paint?

Be cautious. While the 60926's organic-vapor stage covers many solvents, NIOSH and coatings-industry guidance favor a supplied-air respirator for spraying two-component (2K) isocyanate finishes, because isocyanate aerosol has poor warning properties and spray concentrations can exceed an air-purifying respirator's protection factor. Use an air-purifying cartridge for isocyanates only where an exposure assessment and your written program confirm it is adequate.

What particulate does the P100 side capture?

The P100 filter captures at least 99.97% of oil and non-oil airborne particles — dusts, fumes, and mists, including hazards like silica, lead, and welding fume on the particulate side. That is why the 60926 works where gas and particulate hazards occur together; the sorbent handles the gases and the P100 handles the dust.

How should I store the 60926 between uses?

Store it sealed in an airtight bag, away from the contaminants it filters, and out of heat and direct sun. Leaving a cartridge open lets it passively load with vapor and shortens its service life. Note the date you first open it and factor that into your change schedule.
