3M 6002 Acid Gas Respirator Cartridge

3M 6002 Overview

The 3M 6002 is a NIOSH-approved acid gas respirator cartridge for 3M bayonet respirators, carrying the white NIOSH color band. It adsorbs acid-gas vapors — chlorine, hydrogen chloride, sulfur dioxide, chlorine dioxide, and hydrogen fluoride — and twist-locks onto 3M reusable half masks and full facepieces in a matched pair. Reach for the 6002 when your single confirmed hazard is acid gas; it is the focused, lowest-cost cartridge for that exposure.

It is a gas/vapor cartridge only — there is no particulate filter inside, and it does not protect against organic solvent vapor or ammonia. If dust or mist is also in the air, pair it with a 3M 5N11 or 5P71 prefilter behind a 501 retainer, or move to the all-in-one 3M 60922 (acid gas + P100). To verify the right class for your job, work through the how to choose a respirator cartridge guide, the 3M filter & cartridge guide, and the cartridge color chart, or browse the 3M filters and cartridges collection.

Where the 3M 6002 Fits in Respirator Selection

The 6002 is a single-class gas cartridge — choose it only after acid gas is confirmed as your hazard, ideally through an industrial-hygiene assessment of the actual contaminants present.

• Acid gas vapor only (chlorine, HCl, SO₂, ClO₂, HF) → the 6002.
• Acid gas + dust or mist → 6002 with a prefilter, or the 3M 60922 with built-in P100.
• Acid gas + organic solvent vapor → the combination 3M 6003 (OV/AG). Compare gas versus particulate logic in organic vapor vs P100.
• Acid gas + organic vapor + dust → the 3M 60923 (OV/AG/P100). For the broader framework, see respirator filter types explained.

Who Should Buy the 3M 6002?

Buy the 6002 if your confirmed hazard is acid-gas vapor and there is no meaningful dust or solvent vapor — water and wastewater operators dosing chlorine, pool-chemical handlers, bleaching and pulp processes, and acid-transfer crews.

Choose a different part if:

• Dust or mist is also present → add a 5N11/5P71 prefilter, or buy the 3M 60922 (acid gas + P100).
• Organic solvent vapor is also in the air → the combination 3M 6003 (OV/AG).
• You face organic vapor, acid gas, and dust together → the 3M 60923 (OV/AG/P100).

What Does the 3M 6002 Protect Against?

What the 3M 6002 Does NOT Protect Against

• Dust / particulate (no filter)
• Organic solvent vapor
• Ammonia & methylamine
• Formaldehyde
• Carbon monoxide
• Oxygen deficiency
• Unknown atmospheres
• IDLH conditions

Safety: The 3M 6002 is rated only for acid-gas vapor. It has no particulate filter and does not protect against organic vapor, ammonia, formaldehyde, or carbon monoxide, and no cartridge adds oxygen. Chlorine and other acid gases can be immediately dangerous at high concentrations — oxygen-deficient, unknown, and IDLH atmospheres require supplied air, SCBA, or another solution specified by a qualified safety professional. Where dust is also present, add a 5N11 prefilter or use the 3M 60922.

Best Applications for the 3M 6002

Water & Wastewater Chlorination

Chlorine dosing and disinfection are the classic acid-gas exposure, and the 6002 is the dedicated cartridge for chlorine and chlorine-dioxide vapor during routine operation and leak checks below IDLH. Verify concentrations against your program; if levels approach IDLH, switch to supplied air. See the color chart to confirm the white band matches your hazard.

Pool Chemicals & Bleaching

Pool-chemical rooms and bleaching processes release chlorine and sulfur-dioxide vapor where the 6002 fits a fit-tested 3M facepiece. If powders or mists from dry chemicals are also airborne, add a prefilter or choose the 60922 for combined gas and P100 protection, and review the acid gas cartridges collection.

Acid Handling & Transfer

Hydrochloric and hydrofluoric acid transfer release HCl and HF vapor, which the 6002 is rated to capture. If organic solvents are part of the same task, step to a combination cartridge from the combination cartridges collection such as the 6003.

3M 6002 Pros & Cons

Compatible 3M Respirators

The 3M 6002 uses the standard 3M bayonet connection and mounts to 3M reusable half masks and full facepieces:

Standard 3M bayonet connection. Does not fit Honeywell North, Moldex, MSA, GVS, or 3M Secure Click respirators. For particulate, add a 5N11/5P71 prefilter with the 501 retainer.

3M 6002 vs Other 3M Gas Cartridges

3M 6002 vs 60922

Both protect against the same acid gases; the difference is the particulate filter. The 6002 is gas-only, so if dust or mist is present you must add a prefilter. The 3M 60922 builds a P100 filter into the same acid-gas cartridge. Buy the 6002 for clean acid-gas environments at the lowest cost. Buy the 60922 when dust or mist is also in the air and you want one-piece gas-plus-particulate protection.

3M 6002 vs 6003

The 6002 is single-class (acid gas); the 3M 6003 is a combination cartridge that covers organic vapor and acid gas together. Buy the 6002 when acid gas is your only hazard — it is cheaper and purpose-built. Buy the 6003 when solvent vapor is also present and you need both classes in one cartridge; for that same mix plus dust, look at the 60923.

3M 6002 Quick Answers

What is the 3M 6002?

The 3M 6002 is a NIOSH-approved acid gas respirator cartridge for 3M bayonet respirators. It adsorbs acid-gas vapors such as chlorine, hydrogen chloride, sulfur dioxide, chlorine dioxide, and hydrogen fluoride, and carries the white NIOSH color band. It has no particulate filter.

Does the 3M 6002 protect against chlorine?

Yes. Chlorine is one of the acid gases the 6002 is rated for, along with hydrogen chloride, sulfur dioxide, chlorine dioxide, and hydrogen fluoride.

What is the 3M 6002 color code?

White — the NIOSH color band for acid-gas protection.

Does the 3M 6002 protect against organic vapor or ammonia?

No. The 6002 is rated only for acid gas. For organic vapor plus acid gas use the 3M 6003; for ammonia and methylamine use a green-band ammonia cartridge instead.

3M 6002 Frequently Asked Questions

What is the 3M 6002 used for?

The 6002 is used for acid-gas vapor protection — water and wastewater chlorination, pool-chemical handling, bleaching, and acid transfer — on 3M bayonet respirators.

Which gases does the 3M 6002 protect against?

The 6002 is rated for acid gases: chlorine, hydrogen chloride, sulfur dioxide, chlorine dioxide, and hydrogen fluoride. It carries the white NIOSH color band identifying acid-gas protection.

Does the 3M 6002 have a particulate filter?

No. The 6002 is a gas/vapor cartridge only. For dust, add a 3M 5N11 or 5P71 prefilter with a 501 retainer, or use the 3M 60922, which includes P100.

What respirators does the 3M 6002 fit?

It 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 6002 and 60922?

Both protect against the same acid gases. The 60922 adds a built-in P100 filter for dust; the 6002 is gas-only and needs a separate prefilter if particulate is present.

What is the NIOSH color code for the 3M 6002?

White, which identifies acid-gas protection.

Does the 3M 6002 protect against ammonia or formaldehyde?

No. The 6002 is not rated for ammonia, methylamine, or formaldehyde. Those hazards require different cartridges identified by their own NIOSH color bands.

Can I use the 3M 6002 for organic solvent vapor?

No. Organic solvent vapor requires an organic-vapor cartridge. If you face solvent vapor and acid gas together, use the combination 3M 6003, or the 60923 if dust is also present.

How many 3M 6002 cartridges do I need?

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

Is the 3M 6002 good for chlorine in water treatment?

Yes, for chlorine vapor below IDLH on a fit-tested 3M respirator. At high concentrations or unknown levels, chlorine can be immediately dangerous and requires supplied air or SCBA.

When should I replace the 3M 6002?

Replace it on your employer's change-out schedule, or sooner if you detect an acid-gas odor or irritation, breathing becomes difficult, or the cartridge is damaged.

Should I buy the 3M 6002 or the 60922?

Buy the 6002 for clean acid-gas environments at the lowest cost. Buy the 60922 if dust or mist is also present and you want acid-gas-plus-P100 protection in one cartridge.
