3M 6007 Mercury Vapor / Organic Vapor / Acid Gas Respirator Cartridge

3M 6007 Overview

The 3M 6007 is a NIOSH-approved mercury vapor, organic vapor, and acid gas respirator cartridge for 3M bayonet respirators, with a built-in mercury end-of-service-life indicator (ESLI). It adsorbs mercury vapor together with organic solvent vapor and acid gases such as chlorine, sulfur dioxide, and hydrogen sulfide, and twist-locks onto 3M reusable half masks and full facepieces. Reach for the 6007 when mercury vapor is the defining hazard and organic vapor or acid gas is in the mix — the ESLI removes the guesswork from change-out timing.

It is a gas/vapor cartridge only — it has no particulate filter. If dust or mist is also present, pair it with a 3M 5N11 or 5P71 prefilter and 501 retainer, or choose the all-in-one 3M 60927 (mercury/OV/AG + P100). To confirm the right class, use 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 6007 Fits in Respirator Selection

The 6007 is a mercury-and-multi-gas cartridge — select it once a hazard assessment confirms mercury vapor is present alongside organic vapor or acid gas, and that dust is not a concern.

• Mercury vapor + organic vapor + acid gas, no dust → the 6007, with its mercury ESLI.
• Mercury + OV + acid gas with dust present → the 3M 60927 with built-in P100, or add a prefilter to the 6007.
• Several gases but no mercury → a multi-gas cartridge such as the 3M 6006 or the 3M 60926 (multi-gas/P100).

Who Should Buy the 3M 6007?

Buy the 6007 if a hazard assessment confirms mercury vapor with organic vapor or acid gas and there is no significant dust — mercury reclamation and recycling crews, chlor-alkali plant operators, and instrument, dental, and laboratory staff handling mercury.

Choose a different part if:

• Dust or mist is also present → add a 5N11/5P71 prefilter, or buy the 3M 60927 (mercury/OV/AG + P100).
• There is no mercury, just multiple gases → the 3M 6006 or 3M 60926.
• You need P100 particulate protection on its own → the 3M 2091 P100 filter.

What Does the 3M 6007 Protect Against?

What the 3M 6007 Does NOT Protect Against

• Dust / particulate (no filter)
• Ammonia
• Methylamine
• Formaldehyde
• Carbon monoxide
• Oxygen deficiency
• Unknown atmospheres
• IDLH conditions

Safety: The 3M 6007 is rated for mercury vapor, organic vapor, and acid gas only. It has no particulate filter and does not protect against ammonia, formaldehyde, or carbon monoxide, and no cartridge adds oxygen. Mercury vapor is highly toxic — change the cartridge at the first indication from the mercury ESLI and do not wait for odor or symptoms. 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 60927.

Best Applications for the 3M 6007

Mercury Reclamation & Recycling

Mercury reclamation, recovery, and recycling expose workers to mercury vapor often mixed with solvent vapor, and the 6007 is the dedicated cartridge for that combination. The mercury ESLI is the key feature here — it tells crews exactly when to change out rather than relying on odor, which mercury does not provide. For mercury work where dust is also airborne, step up to the 60927 for combined gas and P100 protection.

Chlor-Alkali & Acid Gas Process Work

Chlor-alkali plants generate both mercury vapor and acid gases such as chlorine and hydrogen sulfide, and the 6007 covers that mix on a fit-tested 3M facepiece. If a particulate hazard joins the gases, you need an added prefilter or the P100 version — see the color chart and the combination cartridges collection.

Instrument, Dental & Laboratory Mercury Handling

Instrument repair, dental amalgam work, and lab processes can release mercury vapor alongside solvents, where the 6007 covers the vapor and acid-gas hazard with the assurance of the ESLI. Add a prefilter if powders or mists are also airborne, and review the multi-gas cartridges collection if mercury is not actually present.

3M 6007 Pros & Cons

Compatible 3M Respirators

The 3M 6007 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 6007 vs Other 3M Gas Cartridges

3M 6007 vs 60927

Both cover mercury vapor, organic vapor, and acid gas with a mercury ESLI; the difference is the particulate filter. The 6007 is gas-only, so if dust is present you must add a prefilter. The 3M 60927 builds a P100 filter into the same mercury/OV/AG cartridge. Buy the 6007 for clean mercury-vapor environments at the lower cost. Buy the 60927 when dust or mist is also in the air and you want one-piece gas-plus-particulate protection.

3M 6007 vs 6006

The 6007 is built around mercury vapor and carries a mercury ESLI; the 3M 6006 is a general multi-gas cartridge for organic vapor, acid gas, and ammonia but is not rated for mercury. Buy the 6007 whenever mercury vapor is part of the exposure — only it provides the mercury end-of-service-life indicator. Buy the 6006 when there is no mercury and you simply need broad multi-gas coverage including ammonia.

What is the 3M 6007?

The 3M 6007 is a NIOSH-approved mercury vapor, organic vapor, and acid gas respirator cartridge for 3M bayonet respirators. It includes a built-in mercury end-of-service-life indicator and has no particulate filter.

What is the mercury ESLI on the 3M 6007?

The ESLI is an end-of-service-life indicator that changes to signal when the cartridge's mercury sorbent is nearing exhaustion. Because mercury vapor has no odor warning, the ESLI is how you know to change out the 6007.

Does the 3M 6007 protect against dust?

No. The 6007 is a gas cartridge with no particulate filter. If dust or mist is present, add a 3M 5N11 or 5P71 prefilter with a 501 retainer, or use the 3M 60927, which has P100 built in.

Does the 3M 6007 protect against chlorine and hydrogen sulfide?

Yes. The 6007 is rated for acid gases including chlorine, sulfur dioxide, and hydrogen sulfide, along with mercury vapor and organic vapor.

3M 6007 Frequently Asked Questions

What is the 3M 6007 used for?

The 6007 is used for mercury vapor protection combined with organic vapor and acid gas — mercury reclamation, chlor-alkali process work, and instrument, dental, and lab mercury handling — on 3M bayonet respirators.

Does the 3M 6007 protect against mercury vapor?

Yes. The 6007 is NIOSH-rated for mercury vapor and includes a mercury end-of-service-life indicator that tells you when to change the cartridge.

How does the mercury ESLI work on the 3M 6007?

The ESLI is a visual indicator that changes as the mercury sorbent approaches exhaustion. Mercury vapor gives no odor warning, so you should change the cartridge at the ESLI indication rather than waiting to smell or feel anything.

Does the 3M 6007 have a particulate filter?

No. The 6007 is a gas/vapor cartridge only. For dust, add a 3M 5N11 or 5P71 prefilter with a 501 retainer, or use the 3M 60927, which includes P100.

Does the 3M 6007 protect against acid gases like chlorine?

Yes. The 6007 covers acid gases including chlorine, sulfur dioxide, and hydrogen sulfide, in addition to mercury vapor and organic vapor.
