MSA GME Respirator Cartridge Overview

The MSA GME is a NIOSH-approved multi-gas cartridge for the MSA Comfo system. It adsorbs organic vapor, acid gas, ammonia, methylamine and formaldehyde and carries a olive (multi-gas) band. As a Comfo cartridge it fits MSA Comfo Classic, Comfo II, Ultra-Twin and Ultra-Elite respirators. Start with our guide to choosing a respirator cartridge, confirm the band on the respirator cartridge color chart, and see MSA Comfo vs Advantage if you are unsure which system you own.

The MSA GME belongs to the MSA respirator filters and cartridges range. It is a gas cartridge only — for dust, step up to the GME/P100 combination cartridge, which builds a P100 filter in.

Where the MSA GME Fits in Cartridge Selection

Confirm the hazard before the cartridge. The MSA GME handles multi-gas gas — not particulate. If you also face dust or mist, our organic vapor vs P100 guide and filter types explained cover when to move to a combination cartridge.

Who Should Buy the MSA GME?

Buy it if your exposure is multi-gas with no significant dust, on an MSA Comfo facepiece. Choose another cartridge if your hazard differs: for multi-gas plus dust use the GME/P100, and for a broader gas mix see the MSA Comfo GME multi-gas cartridge.

What Does the MSA GME Protect Against?

What the MSA GME Does NOT Protect Against

The MSA GME does not capture particulate or gases outside its approved list. For dust, step up to the GME/P100 combination cartridge, which builds a P100 filter in; for a different gas, match the MSA cartridge to the hazard.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the MSA GME in an oxygen-deficient or IDLH (immediately dangerous to life or health) atmosphere, in unknown concentrations, or against gases with no warning properties — those conditions require a supplied-air or SCBA system, not a cartridge respirator.

Best Applications

Maintenance & response

Mixed or unknown gas hazards; see GME/P100 vs 3M 60926.

Labs

Moving between solvents, acids, ammonia and formaldehyde; for dust use the GME/P100.

Pros & Cons

MSA GME vs Other MSA Cartridges

MSA GME vs the Alternatives

How it compares to the closest MSA options:

• GME vs GME/P100: same broad gas coverage; the GME/P100 adds a P100 filter.
• GME vs GMC: the GME adds ammonia and formaldehyde over the GMC.
• GME vs GMT: the GMT is a multi-gas cartridge also rated for tritium oxide service.

MSA GME Quick Answers

Does the MSA GME filter dust?

No — it is gas-only; for particulate use the GME/P100 or add a prefilter.

Does the MSA GME fit my MSA respirator?

It fits the MSA Comfo family. Check your facepiece against the MSA half-mask and full-face ranges.

Is the MSA GME reusable?

The cartridge is used until its service life is reached; the respirator is reusable across many cartridge changes.

MSA GME Specifications

Compatible MSA Respirators

The MSA GME uses the MSA Comfo threaded-bayonet connection, so it mounts on the Comfo Classic half-mask and Ultra-Elite full-face respirators (and the Comfo II and Ultra-Twin). It is not interchangeable with the MSA Advantage series, and does not fit 3M, Honeywell North or other brands.

MSA GME Frequently Asked Questions

What does the MSA GME protect against?

The MSA GME is a multi-gas cartridge. It adsorbs organic vapor, acid gas, ammonia, methylamine and formaldehyde. It is gas-only and does not filter particulate; it does not protect against gases outside its approved list.

Does the MSA GME filter dust?

No. It is a gas cartridge. For dust or mist, step up to the GME/P100 combination cartridge, which builds a P100 filter in.

Which respirators does the MSA GME fit?

It uses the MSA Comfo threaded-bayonet connection and fits the Comfo Classic, Comfo II, Ultra-Twin and Ultra-Elite. It does not fit the Advantage series.

What color band is the MSA GME?

The MSA GME carries a olive (multi-gas) band; confirm it on the cartridge color chart before use.

Is the MSA GME NIOSH-approved?

Yes. The MSA GME is NIOSH-approved under 42 CFR Part 84 for multi-gas. Verify any cartridge against the NIOSH Certified Equipment List.

How is the MSA GME sold?

This listing is the Each. Use Request a Quote for case pricing on volume orders.

How often should I replace the MSA GME?

Replace the cartridge on a documented change-out schedule, when you detect gas or odor breakthrough, or when it is damaged.

Can I add a P100 filter to the MSA GME?

Yes — the easiest route is the GME/P100, which builds a P100 particulate filter into the same gas cartridge.

Is the MSA GME the same as the Advantage version?

No. The chemistry is equivalent, but the connection differs — Comfo and Advantage cartridges are not interchangeable. Match the cartridge to your facepiece.

Is this the genuine MSA GME cartridge?

Yes. WC Safety sells authentic, NIOSH-approved MSA GME cartridges through legitimate supply channels.

What is the difference between the MSA GME and a multi-gas cartridge?

A single-class cartridge is tuned to its listed gases; a multi-gas cartridge covers a broader mix at the cost of a shorter service life against any one gas.

How should I store the MSA GME?

Store it sealed in its original packaging, away from gases and dust, so the sorbent is not used up before you wear it.
