3M 60922 Review: Acid Gas + P100 Cartridge for Chlorine
Editorial Verdict — 3M 60922: 4.4/5
"The 3M 60922 pairs acid-gas protection with a built-in P100, so it suits chlorine, hydrogen chloride, and sulfur dioxide work where mist or dust is also present. It's the right combination for water treatment and acid-process environments — and if organic solvent vapor is also in the air, step up to the 60923, which adds organic vapor on top."
Quick Verdict
The 3M 60922 is a combination acid gas + P100 cartridge — white and magenta banded — for environments where acid gases and airborne particulate occur together. Think chlorine at a water plant with aerosol, or acid processing that also throws dust or mist. It is an upgrade cartridge: the same acid-gas protection as the 6002, with a built-in P100 filter added.
Who should not choose it: if there is no particulate, the gas-only 6002 is lighter and cheaper; if your hazard is solvent vapor rather than acid gas, that is an organic-vapor cartridge job; and it does nothing for ammonia or formaldehyde.
The closest alternative is the 3M 60923, which adds organic vapor on top of acid gas + P100. New to combination cartridges? Start with how to choose a respirator cartridge and the acid gas cartridge guide.
What the 3M 60922 Is Designed For
The 60922's protection category is acid gas plus P100 particulate. It combines an acid-gas sorbent with an integrated P100 filter — the highest particulate class, oil-proof, capturing at least 99.97% of airborne particles. Its two NIOSH bands (white for acid gas, magenta for P100) signal both protections in one cartridge. The acid gases on its approval typically include chlorine (Cl₂), hydrogen chloride (HCl), sulfur dioxide (SO₂), chlorine dioxide, and hydrogen fluoride, with hydrogen sulfide for escape only.
Intended applications are acid-gas workplaces that also generate particulate: water and wastewater chlorination, acid handling and processing, plating, etching, and pickling with acid mist, and chemical operations where acid gas mixes with dust. In the 3M lineup, the 60922 sits one rung above the gas-only 6002 — same acid-gas coverage, with particulate added — and one rung below the 60923, which also covers organic vapor. For the full ladder see the 3M respirator cartridge guide.
Key Specifications
| Attribute | 3M 60922 Detail |
|---|---|
| Protection type | Acid gas + P100 (combination); white + magenta bands |
| Filter rating | P100 (≥99.97%, oil-proof) integrated |
| Gas coverage | Chlorine, HCl, SO₂, ClO₂, HF; H₂S (escape only) |
| Compatible respirator series | 3M 6000, 6500QL, 7500 half masks; 6000 & 7800S full facepieces (bayonet) |
| Common applications | Water treatment, acid processing, plating/etching mist |
| Better alternative when… | No particulate → 6002; solvent vapor present → 60923; organic vapor instead → 60921 |
Real-World Use Cases
The 60922 fits acid-gas tasks that also involve mist or dust:
- Water & wastewater treatment: chlorine and chlorine dioxide handling at dosing stations, where aerosol may also be present. See cartridges for chlorine.
- Chemical processing: hydrogen chloride and sulfur dioxide operations that also generate particulate or mist.
- Plating, etching & pickling: acid baths producing acid mist alongside the gas — the P100 captures the aerosol.
- Manufacturing & maintenance: acid-gas tasks near dusty operations, where a gas-only cartridge would leave particulate uncovered.
- Pulp, paper & bleaching: chlorine-based bleaching environments within exposure limits.
If the air has acid gas but no particulate, you are carrying a filter you do not need — that is a 6002 job. If solvent vapor is also present, move up to the 60923.
What This Cartridge Does Well
- One-piece convenience: acid gas and P100 particulate in a single cartridge — no stacking a 5N11 prefilter and 501 retainer on a gas-only unit.
- Built for chlorine-plus-mist work: the water-treatment scenario (acid gas + aerosol) is exactly what it targets.
- Highest particulate class: P100 is oil-proof and ≥99.97% efficient, handling acid mists that lower-rated filters are not rated for.
- Broad compatibility: fits every current 3M bayonet half mask and full facepiece, so one SKU covers a mixed fleet.
- Clear position in the lineup: easy to reason about — a 6002 with P100 added, and a step below the 60923.
Where the 3M 60922 Is Not the Right Choice
The 60922 is a combination cartridge, but it is still acid-gas-class on the gas side. It is the wrong choice when:
- There is no particulate. For gas-only acid-gas work, the lighter, cheaper 6002 is the better value — see the 3M 6002 review.
- Particulate is the only hazard. For pure dust or fume, a plain 2091 P100 filter is lighter and lower cost than a combination cartridge.
- Organic solvent vapor is present. Add organic vapor coverage with the 60923 (OV/AG/P100) — read the 3M 60923 review.
- Ammonia or formaldehyde is present. Acid-gas sorbent does not cover those — use a multi-gas cartridge such as the 60926.
- The atmosphere is IDLH, oxygen-deficient, or unknown. A large chlorine release is an emergency — no air-purifying cartridge applies; use supplied air or SCBA.
3M 60922 vs Similar 3M Cartridges
The 60922 is easiest to place by what each neighbor adds or removes:
| Cartridge | Coverage | Choose Instead of 60922 When |
|---|---|---|
| 6002 | Acid gas | No particulate present (gas-only, cheaper) |
| 60922 | Acid gas + P100 | — (baseline: acid gas + mist/dust) |
| 60923 | OV + acid gas + P100 | Organic solvent vapor also present |
| 60921 | Organic vapor + P100 | The gas is solvent vapor, not acid gas |
| 2091 | P100 only | Particulate is the only hazard |
For related context, see the 3M 6003 OV/acid-gas review, 3M 60921 vs 60923, and the gas-vs-particulate breakdown in organic vapor vs P100.
Compatible Respirators
The 60922 uses the standard 3M bayonet connection and seats on the full current range of 3M bayonet facepieces:
- 3M 6000 Series half masks — the 6100/6200/6300
- 3M 6500QL Series half masks — the 6501/6502/6503 Rugged Comfort respirators
- 3M 7500 Series half masks — the 7500 Series silicone half masks
- 3M 6000 Series full face — the 6000 full facepieces (APF 50)
- 3M 7800S Series full face — the 7800S full facepieces
- 3M Ultimate FX FF-400 full face — the Ultimate FX FF-400 respirators
It does not fit the 3M Secure Click line (a different mount) or any non-3M facepiece — cartridge mounts are brand-specific. See are respirator cartridges universal?
Who Should Buy This Cartridge?
- Water and wastewater operators handling chlorine and chlorine dioxide where aerosol or dust is also present.
- Chemical and process workers exposed to acid gases (HCl, SO₂) alongside particulate or acid mist.
- Plating, etching, and pickling crews working over acid baths that produce both gas and mist.
- Not the right choice for gas-only acid-gas work (use the 6002), particulate-only tasks (use the 2091), solvent vapor (use the 60921/60923), or ammonia and formaldehyde.
Final Recommendation
The 3M 60922 is the right cartridge whenever acid gas and particulate appear together — most commonly chlorine work in water treatment and acid processing with mist. It removes the hassle of stacking a prefilter and gives you the highest particulate class in the same unit. Buy it for acid-gas-plus-particulate environments, and pair it with whichever 3M facepiece fits your crew; a full facepiece is worth considering since chlorine and other acid gases irritate the eyes.
The closest gas-only alternative is the 6002 when no particulate is present; the upgrade for added solvent vapor is the 60923. Still deciding? Use how to choose a respirator cartridge, the acid gas cartridge guide, and browse all 3M respirator cartridges and filters.

"Chlorine and mist covered in one cartridge"
At the dosing station we get chlorine plus aerosol off the tanks. The 60922 handles both, so I'm not adding a prefilter to a 6002. On a 7502 it's comfortable for the rounds. SCBA stays staged for any real leak.

"Right pick for the plating line"
Acid mist over the tanks meant a gas-only cartridge wasn't enough. The 60922's P100 catches the aerosol while the acid-gas side handles the fumes. One cartridge, less to manage on the floor.

"Great combo — just confirm it's acid gas you have"
Works well for our SO₂ and chlorine tasks with dust. The reminder I'd give: it's acid-gas, not organic vapor — when solvents showed up I had to switch to the 60923. For straight acid-gas-plus-particulate it's spot on.

Frequently Asked Questions
What is the 3M 60922 used for?
Acid gas + P100 protection where acid gases and particulate occur together — water/wastewater chlorination, acid processing, and plating/etching with mist — on a 3M bayonet facepiece.
What does the 3M 60922 protect against?
Acid gases (chlorine, HCl, SO₂, ClO₂, HF; H₂S escape only) plus P100 particulate. Not organic vapor, ammonia, or formaldehyde. Confirm the gas list against the SDS. See the cartridge color chart.
Does the 3M 60922 fit 3M 6000 respirators?
Yes — it fits the 3M 6000 (6100/6200/6300), 6500QL, and 7500 half masks, plus 6000 and 7800S full facepieces. It does not fit 3M Secure Click or other brands.
Does the 3M 60922 fit the 3M 7500?
Yes. The 7500 Series uses the same bayonet mount — a comfortable choice for long shifts at a chlorination or acid-process station.
Is the 3M 60922 good for painting?
No — paint fumes are organic vapors, not acid gas. Use an organic vapor cartridge like the 6001, or the 60921 (OV/P100) for spraying.
Is the 3M 60922 good for welding?
The P100 captures weld fume, but if welding is the only hazard a plain 2091 P100 is lighter and cheaper. Choose the 60922 when acid gases are also present.
Is the 3M 60922 P100?
Yes — it has an integrated P100 filter (magenta band) with its acid-gas sorbent (white band). P100 is the highest, oil-proof particulate class.
How often should the 3M 60922 be replaced?
Change the P100 when breathing gets harder (loading); the acid-gas portion follows a written change-out schedule (OSHA 1910.134). Replace on any odor/taste/irritation. See how long respirator cartridges last.
What's the difference between the 3M 60922 and 6002?
Same acid gases, but the 60922 adds a built-in P100. The 6002 is gas-only and cheaper; the 60922 is the choice when mist or dust is present. See the 6002 review.
What's the difference between the 3M 60922 and 60923?
Both add P100 to acid gas; the 60923 also adds organic vapor. Choose it when solvent vapor is also present. See the 60923 review.
Does the 3M 60922 work with full face respirators?
Yes — it fits 3M 6000 full facepieces and 7800S full facepieces, raising the APF from 10 to 50 and protecting the eyes from acid-gas irritation.
What colors are the bands on the 3M 60922?
White (acid gas) and magenta (P100) — a combination cartridge shows both NIOSH bands.
Is the 3M 60922 NIOSH approved?
Yes — for acid gas and P100 under 42 CFR Part 84. Approval applies to the complete assembly, so use it on an approved 3M facepiece with fit testing and medical evaluation.
Is the 3M 60922 good for chlorine?
Chlorine is one of the acid gases on its approval, so the 60922 is common for water treatment within limits — especially with particulate present. It's never appropriate for an IDLH chlorine release, which needs supplied air or SCBA. See cartridges for chlorine.
Do I need a separate prefilter with the 3M 60922?
No — the P100 is built in, so there's no stacking a 5N11 prefilter and 501 retainer the way you would on a gas-only 6002. That integrated design is the 60922's main practical advantage for dusty or misty acid-gas work.
When should I choose a different 3M cartridge instead of the 60922?
No particulate → 6002; solvent vapor present → 60923; organic vapor instead of acid gas → 60921; particulate only → 2091.
