Best 3M Cartridge For Acid Gas

The Best 3M Cartridge for Acid Gas Is the 60923 — OV, Acid Gas and P100 in One

Reviewed by WC Safety Editorial — Last updated 2026-06-30.

Acid gases — chlorine (Cl₂), hydrogen chloride (HCl), sulfur dioxide (SO₂) and chlorine dioxide (ClO₂) — show up in water and wastewater treatment, chemical processing, pool-chemical handling, battery charging rooms and acid-catalyzed coatings. The best-selling 3M answer is the 3M 60923, which pairs an acid-gas + organic-vapor sorbent with an integrated P100 filter — covering acid gas, solvent vapor and particulate in one cartridge. Always confirm the cartridge against your safety data sheets and a hazard assessment — see our respirator cartridge selection guide and the NIOSH cartridge color chart.

Because most acid-gas environments also carry some organic vapor, the combined OV/AG cartridges (60923, 6003) are usually the practical choice over a pure acid-gas cartridge. We rank both, plus the acid-only 6002 for single-hazard jobs and the Secure Click version. For the brand-agnostic view, see our best respirator cartridge for acid gas guide.

Editorial verdict: The 3M 60923 OV/acid-gas/P100 is the best 3M acid-gas cartridge for most buyers — it covers acid gas, organic vapor and particulate in a single cartridge. If your air is dust-free and OV-free, the pure acid-gas 6002 is the lighter, single-hazard option.

All bayonet picks fit the 3M 6000/6500/7500 half masks and 6800/6900 full facepieces. For chlorine and acid environments many buyers pair them with a 3M full-face respirator for eye protection.

The Ranked 3M Picks

1. 3M 60923 P100 Acid Gas Organic Vapor Respirator Cartridge — Best 3M Cartridge for Acid Gas Overall

NIOSH: OV + Acid Gas + P100 · 3M bayonet · Street price ≈ the listed price

The 3M 60923 is the most popular 3M acid-gas cartridge for good reason: it covers chlorine, HCl, SO₂ and chlorine dioxide plus organic vapor, with an integrated P100 filter for any mist or particulate. One cartridge for the realistic acid-process mix — solvent vapor and acid gas rarely travel alone. The clear default for water treatment and chemical handling.

2. 3M 6003 Organic Vapor and Acid Gas Respirator Cartridge — Best Gas-Only OV + Acid Gas

NIOSH: OV + Acid Gas · Gas-only · 3M bayonet · Street price ≈ the listed price

The 3M 6003 is the gas-only version of the 60923 — organic vapor plus acid gas, no particulate layer — for clean, dust-free atmospheres. Cheaper and lighter; snap a 2096 P100/acid-gas filter straight onto each cartridge if particulate appears. The value pick when you don't need integrated P100.

3. 3M 6002 Acid Gas Respirator Cartridge — Best Pure Acid-Gas Cartridge

NIOSH: Acid Gas · Gas-only · 3M bayonet · Street price ≈ the listed price

The 3M 6002 is acid-gas only — no organic-vapor bed — for environments where acid gas is the sole hazard and you want the simplest, most targeted protection. It's a niche pick, since most acid environments also carry OV; verify with your SDS before choosing it over the 6003.

4. 3M 60922 P100 Acid Gas Respirator Cartridge — Best Acid Gas + Particulate (No OV)

NIOSH: Acid Gas + P100 · 3M bayonet · Street price ≈ the listed price

The 3M 60922 pairs pure acid-gas protection with an integrated P100 filter — acid gas plus dust/mist, but no organic vapor. Useful where acid gas and particulate are present but solvents are not (some metal-treatment and battery applications). If OV is also present, step to the 60923.

5. 3M 2096 P100 Respirator Filter Nuisance Acid Gas — Best Add-On Acid-Gas Particulate Filter

NIOSH: P100 + nuisance acid-gas relief · pancake filter · Street price ≈ the listed price

The 3M 2096 P100 filter is a flat P100 filter with nuisance-level acid-gas relief that snaps directly onto a 6001/6003 bayonet cartridge — no 501 retainer is used. It adds 99.97% particulate protection plus minor acid-odor knock-down to gas-only cartridges. The OV/acid relief is nuisance-level only and never replaces a primary acid-gas bed.

6. 3M Secure Click D80923 P100 OV/AG Combination Cartridge — Best Secure Click Acid-Gas Cartridge

NIOSH: OV + Acid Gas + P100 · 3M Secure Click HF-800 · Street price ≈ the listed price

The 3M Secure Click D80923 brings OV/acid-gas/P100 coverage to the HF-800 Secure Click masks with positive push-to-seat seating. Choose it if you run the Secure Click platform — it does not fit bayonet masks.

Quick Comparison Table

How to Match the 3M Cartridge to Your Hazard

Confirm the acid gas. SDS Section 8 will name chlorine, hydrogen chloride, sulfur dioxide or chlorine dioxide. The white-banded acid-gas sorbent (6002/6003/60922/60923) is the match.

Is organic vapor also present? Almost always yes in real plants — choose an OV/acid-gas cartridge (60923 with P100, or 6003 gas-only). Only choose the pure 6002 when the SDS shows acid gas alone.

Particulate in the air? Mist, dust or fume → use a P100 version (60923/60922) or add a 2096 to a gas-only cartridge.

Add eye protection and a change schedule. Chlorine and acid gases irritate eyes — consider a full-face respirator. Acid-gas cartridges have no reliable odor warning at low levels, so a documented change-out schedule is essential. Fit-test per OSHA 1910.134.

Compatible 3M Respirators

Every bayonet-mount cartridge here fits the 3M 6000, 6500 (6501QL/6502QL/6503QL), and 7500 series half-mask respirators and the 6800/6900 full facepieces.

Why trust WC Safety

WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.

Our methodology

Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
