3M 60923 P100 Acid Gas Organic Vapor Respirator Cartridge

3M 60923 Overview

The 3M 60923 is a NIOSH-approved organic vapor / acid gas / P100 combination cartridge that twist-locks onto 3M bayonet respirators — a sorbent bed adsorbs organic-vapor solvents and acid gases while a bonded P100 media captures at least 99.97% of oil and non-oil airborne particles, all in one housing. It wears the magenta P100 band alongside an organic-vapor-plus-acid-gas designation and mounts to 3M reusable half masks and full facepieces. Reach for the 60923 when a single task exposes you to solvent vapor, acid gas, and dust at the same time and you would rather run one cartridge than pair a gas cartridge with a separate particulate filter.

This is a combination cartridge — not a particulate-only filter and not a single-hazard gas cartridge. If your only concern is airborne dust, a P100 particulate filter does the job for less; if the air holds organic vapor and acid gas but no dust, the gas-only 3M 6003 OV/AG cartridge is cheaper. To line protection up with your actual exposure, work through the how to choose a respirator cartridge guide and the 3M filter & cartridge guide, or scan the whole range in the 3M respirator filters and cartridges collection.

Where the 3M 60923 Fits in Respirator Selection

Identify the contaminant first — ideally through an industrial-hygiene assessment — then match the cartridge to it. The 60923 sits in the combination tier: it earns its place only when the air carries a gas/vapor hazard and a particulate hazard together.

• Particulate only (silica, lead, mold, welding fume): a P100 filter like the 3M 2091 is all you need. See how the classes differ in respirator filter types explained and P100 vs N95.
• Gas/vapor only (solvent and acid gas, no dust): a gas-only OV/AG cartridge such as the 3M 6003 is the cheaper fit. Read organic vapor vs P100 and check the respirator cartridge color chart.
• Gas/vapor + particulate (the 60923's job): an OV/AG/P100 combination — the 60923 is the value option in this class, with the 3M 60928 carrying the same protection at a typically higher price.

Who Should Buy the 3M 60923?

Buy the 60923 if your work releases organic-vapor solvents and acid gases at the same time as dust, mist, or overspray, and you run a 3M bayonet respirator — one cartridge covers all three hazards at the lowest price in its class, so you skip stacking parts.

Choose a different part if:

• You only face dust or fume → the 3M 2091 P100 filter costs far less.
• You face organic vapor and acid gas but no dust → the gas-only 3M 6003 (OV/AG) is cheaper.
• You face OV + P100 with no acid gas → the 3M 60921 (OV/P100).
• You face AG + P100 with no organic vapor → the 3M 60922 (AG/P100).
• You face a broader multi-gas mix (adds ammonia and formaldehyde) → the 3M 60926 multi-gas/P100.

What Does the 3M 60923 Protect Against?

The 60923 pairs organic-vapor and acid-gas sorbent with P100 particulate media. It protects against:

What the 3M 60923 Does NOT Protect Against

• Ammonia
• Methylamine
• Formaldehyde
• Carbon monoxide
• Oxygen deficiency
• Unknown atmospheres
• IDLH conditions

Safety: The 3M 60923 guards only against the organic vapors, acid gases, and particulates within its NIOSH rating and assigned cartridge limits. It will not stop ammonia, formaldehyde, carbon monoxide, or other gases outside its approval, and no cartridge supplies oxygen. Oxygen-deficient, unknown, and IDLH atmospheres demand supplied air, SCBA, or another solution specified by a qualified safety professional. If ammonia or formaldehyde is in play, move up to the 3M 60926 multi-gas cartridge.

Best Applications for the 3M 60923

Chemical Processing & Tank Cleaning

The 60923 fits maintenance and cleaning jobs where solvent vapor and acid gas mix with airborne particulate, covering all three on a single bayonet cartridge at the value price in its class. Verify your specific contaminants against the cartridge color chart, and if ammonia or formaldehyde turns up, step up to the 60926.

Mixed-Solvent Spray & Coating

On coating work that throws off both solvent vapor and overspray, the 60923's sorbent bed traps the vapor while the bonded P100 stops the particulate. If the coating is solvent-only with no acid gas, the 60921 (OV/P100) handles it; weigh the alternatives in the combination cartridges collection or the organic vapor cartridges collection.

General Plant & Maintenance Work

Where crews move between varied solvents, trace acid gases, and dust over a shift, the 60923 delivers broad single-cartridge coverage on a fit-tested 3M facepiece without the cost of the pricier 60928. For acid-gas exposure with no organic vapor, compare the 60922 (AG/P100) in the acid gas cartridges collection.

3M 60923 vs Other 3M Combination Cartridges

3M 60923 vs 60928

This is the first comparison most buyers should run, because the two cartridges are the same protection class. The 60923 and the 3M 60928 are both organic-vapor / acid-gas / P100 combination cartridges on the same 3M bayonet platform — the same NIOSH approval, the same hazards covered. The difference is price: the 60923 is the value option, while the 60928 typically lists higher. Unless a facility or procurement standard names the 60928 specifically, the 60923 delivers the same OV/AG/P100 coverage for less.

3M 60923 vs 6003

The dividing line here is particulate. The 3M 6003 is a gas-only organic-vapor / acid-gas cartridge with no P100 layer, so it costs less but offers no particulate filtration. The 60923 adds the bonded P100 on top of the same OV/AG sorbent. Choose the 6003 when the air holds solvent vapor and acid gas but no dust, and choose the 60923 when dust, mist, or overspray is also present — pairing a 6003 with a separate filter and retainer usually lands near the 60923's all-in-one price anyway.

3M 60923 vs 2091

This is a class difference, not a value question. The 3M 2091 is a P100 particulate filter only — it stops dust, fume, and mist but no gas or vapor. The 60923 layers organic-vapor and acid-gas sorbent on top of P100. Use the 2091 when the hazard is particulate alone; use the 60923 when solvent vapor or acid gas is also in the air. A 2091 in a vapor or acid-gas environment leaves the gas hazard unaddressed.

3M 60923 Frequently Asked Questions

What does the 3M 60923 protect against?

The 60923 protects against organic-vapor solvents, acid gases (such as chlorine, hydrogen chloride, sulfur dioxide, hydrogen fluoride, and chlorine dioxide), and particulates at P100 (99.97%) efficiency. It does not stop ammonia, formaldehyde, or carbon monoxide.

Does the 3M 60923 include a particulate filter?

Yes. The 60923 carries a bonded P100 particulate layer, so it captures dust, fume, and mist alongside gas and vapor — no separate filter or retainer is required.

Is the 3M 60923 cheaper than the 60928?

Generally, yes. The 60923 and 60928 are the same OV/AG/P100 protection class, and the 60923 is the value-priced option. Unless your program specifies the 60928, the 60923 gives identical coverage for less.

What respirators does the 3M 60923 fit?

The 60923 fits 3M bayonet respirators: the 6000, 6500QL, and 7500 half masks and the 6000, 7800S, and Ultimate FX FF-400 full facepieces. It does not fit Honeywell North, Moldex, MSA, GVS, or 3M Secure Click.

What is the difference between the 3M 60923 and the 6003?

The 6003 is a gas-only OV/AG cartridge with no particulate filtration, while the 60923 adds a P100 layer to the same organic-vapor and acid-gas sorbent. Choose the 6003 when there is no dust, and the 60923 when dust, mist, or overspray is also present.

Is the 3M 60923 good for spray painting?

Yes, when the coating gives off both solvent vapor and overspray — the sorbent layer captures the vapor and the P100 layer captures the particulate. If no acid gas is present, the 60921 (OV/P100) covers spray painting too, often for less.

Does the 3M 60923 protect against carbon monoxide?

No. No air-purifying cartridge protects against carbon monoxide. CO exposure requires a supplied-air respirator or SCBA selected by a qualified safety professional.

Does the 3M 60923 protect against formaldehyde?

No. The 60923 is not rated for formaldehyde. For formaldehyde exposure, use the 3M 60926 multi-gas/P100 cartridge.

What is the NIOSH color code for the 3M 60923?

The 60923 shows the magenta P100 band with the organic-vapor and acid-gas designation — magenta marks P100 particulate protection and the cartridge is rated for organic vapor plus acid gas.

How many 3M 60923 cartridges do I need?

3M bayonet cartridges are installed as a pair — one on each side of the facepiece. Confirm the exact pack quantity on the current product listing before ordering, since packaging can vary.

When should I replace the 3M 60923?

Replace the cartridge on your employer's change-out schedule, or sooner if it is damaged, breathing gets harder, or you notice odor, taste, or irritation — an early warning of gas or vapor breakthrough.

Should I buy the 3M 60923 or a separate cartridge and filter?

The 60923 combines gas, vapor, and P100 protection in one housing, which is simpler and often cheaper than stacking an OV/AG cartridge with a separate particulate filter and retainer. If your hazard is single-class, a dedicated cartridge or filter still costs less.
