3M 60927 P100 Mercury Vapor Organic Vapor Acid Gas Respirator Cartridge

3M 60927 Overview

The 3M 60927 is a NIOSH-approved specialty mercury vapor / organic vapor / acid gas / P100 combination cartridge for 3M bayonet respirators, sold as a pair. It is the cartridge to buy when mercury vapor is your controlling hazard, with added protection for organic vapor, chlorine and acid gases, and a bonded P100 filter that captures at least 99.97% of oil and non-oil particles. Mercury cartridges include an end-of-service-life indicator (ESLI) that signals when the mercury sorbent is expended — a requirement for mercury service.

The 60927 is a niche, premium cartridge. If your air does not contain mercury, you are paying for a sorbent you do not need — the 3M 60926 multi-gas/P100 or the 3M 60928 (OV/AG/P100) are the right combination cartridges instead. To confirm the 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 60927 Fits in Respirator Selection

The 60927 is a multi-hazard combination cartridge defined by its mercury sorbent — select it only when mercury vapor is confirmed present, ideally via an industrial-hygiene assessment.

• Mercury vapor (+ OV/acid gas/dust) → the 60927, the only one of these with a mercury sorbent and ESLI.
• Mercury vapor, no dust → the gas-only 3M 6007 (mercury/OV/acid gas without P100).
• No mercury, broad gases + dust → the 3M 60926 multi-gas/P100. Compare protection in organic vapor vs P100.
• Particulate only → a P100 filter such as the 3M 2091; see filter types explained.

Who Should Buy the 3M 60927?

Buy the 60927 if mercury vapor is a confirmed hazard — mercury recovery and reclamation, chlor-alkali operations, instrument and thermometer repair, dental and lab mercury handling, and mercury spill remediation — and your air may also carry organic vapor, chlorine, or dust.

Choose a different part if:

• No mercury is present → the broader 3M 60926 (multi-gas/P100) or the 3M 60928 (OV/AG/P100).
• Mercury is present but there is no dust → the gas-only 3M 6007.
• Your only hazard is solvent vapor → the 3M 6001.

What Does the 3M 60927 Protect Against?

What the 3M 60927 Does NOT Protect Against

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

Safety: The 3M 60927 protects only against the mercury vapor, organic vapor, acid gas, and particulates within its NIOSH rating and assigned limits. It does not protect against ammonia, formaldehyde, or carbon monoxide, and no cartridge adds oxygen. Mercury vapor is highly toxic — replace the cartridge when the ESLI indicates end of service life and never beyond it. Oxygen-deficient, unknown, and IDLH atmospheres require supplied air, SCBA, or another solution specified by a qualified safety professional.

Best Applications for the 3M 60927

Mercury Recovery & Chlor-Alkali

Mercury reclamation and chlor-alkali operations expose workers to mercury vapor alongside chlorine and particulate — exactly the mix the 60927 is built for, with its ESLI tracking mercury service life. Verify exposure against your program and switch to supplied air if levels approach IDLH.

Instrument, Lab & Dental Mercury Handling

Thermometer and manometer repair, dental amalgam work, and lab mercury handling produce mercury vapor where the 60927 provides combined gas, vapor, and P100 protection on a fit-tested 3M facepiece. For mercury vapor without dust, the gas-only 3M 6007 is the lighter option.

Mercury Spill Remediation

Mercury spill cleanup involves vapor plus particulate and sometimes solvents, which the 60927 handles in one cartridge. Browse related combination options in the combination cartridges collection.

3M 60927 vs Other 3M Combination Cartridges

3M 60927 vs 60926

The deciding factor is mercury. The 60927 carries a mercury-vapor sorbent and ESLI; the 3M 60926 is a broader multi-gas/P100 cartridge (adding ammonia, methylamine, and formaldehyde) but has no mercury protection. Buy the 60927 when mercury vapor is present. Buy the 60926 — usually for less — when your hazard is a mix of common gases and dust with no mercury.

3M 60927 vs 6007

Both protect against mercury vapor, organic vapor, and acid gas. The difference is particulate: the 60927 has a bonded P100 filter, while the 3M 6007 is gas-only. Buy the 60927 when dust or mist is present with the mercury vapor. Buy the lighter 6007 when the air is clean of particulate, or add a prefilter to it.

3M 60927 Quick Answers

What is the 3M 60927?

The 3M 60927 is a NIOSH-approved combination cartridge that protects against mercury vapor, organic vapor, acid gas (chlorine), and particulate at P100 (99.97%) efficiency, for 3M bayonet respirators. It includes a mercury end-of-service-life indicator and is sold as a pair.

Does the 3M 60927 protect against mercury vapor?

Yes. Mercury vapor is the 60927's defining protection, backed by an end-of-service-life indicator (ESLI) that signals when the mercury sorbent is expended.

Is the 3M 60927 P100?

Yes. The 60927 has a bonded P100 particulate layer, filtering at least 99.97% of oil and non-oil airborne particles in addition to its gas and vapor protection.

What is the difference between the 60927 and 60926?

The 60927 adds mercury vapor protection with an ESLI; the 60926 is a broader multi-gas/P100 cartridge with no mercury sorbent. Choose by whether mercury is present.

3M 60927 Frequently Asked Questions

What is the 3M 60927 used for?

The 60927 is used where mercury vapor is present alongside organic vapor, acid gas, or dust — mercury recovery, chlor-alkali plants, instrument and dental mercury handling, and spill remediation — on 3M bayonet respirators.

Does the 3M 60927 protect against mercury?

Yes. Mercury vapor is its defining protection, with an end-of-service-life indicator that tells you when the mercury sorbent is expended and the cartridge must be replaced.

What is an ESLI on the 3M 60927?

An end-of-service-life indicator is a passive indicator that changes to signal when the mercury sorbent has reached the end of its service life — replace the cartridge at that point and never use it beyond it.

Is the 3M 60927 a P100 cartridge?

Yes. It includes a bonded P100 filter capturing at least 99.97% of oil and non-oil particles in addition to mercury vapor, organic vapor, and acid-gas protection.

What respirators does the 3M 60927 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 60927 and 60926?

The 60927 adds mercury vapor protection with an ESLI; the 60926 is a broader multi-gas/P100 cartridge without mercury. Choose by whether mercury vapor is present.

What is the difference between the 3M 60927 and 6007?

Both cover mercury vapor, organic vapor, and acid gas. The 60927 adds a P100 particulate filter; the 6007 is gas-only. Use the 60927 when dust is present.

Does the 3M 60927 protect against ammonia or formaldehyde?

No. The 60927 is not rated for ammonia, methylamine, or formaldehyde. For those, use the 3M 60924 (ammonia) or 60925 (formaldehyde).

How many 3M 60927 cartridges come in a pack?

The 60927 is sold as a pair — two cartridges, one for each side of the facepiece. Confirm the current pack quantity on the listing before ordering.

When should I replace the 3M 60927?

Replace it when the mercury ESLI indicates end of service life, or sooner if it is damaged, breathing becomes difficult, or you detect odor or taste — and always per your respiratory protection program.

Is the 3M 60927 good for chlor-alkali work?

Yes. Chlor-alkali operations involve mercury vapor, chlorine acid gas, and particulate, which the 60927 covers in one cartridge on a fit-tested 3M respirator.

Should I buy the 3M 60927 or the 60926?

Buy the 60927 only if mercury vapor is present. If there is no mercury, the 60926 covers a broader set of common gases plus P100, usually at a lower price.
