MSA 815355 Advantage Gma Organic Vapor Cartridge Review

Is the MSA 815355 Advantage GMA the right organic vapor cartridge for your respirator?

Published June 10, 2026 · Last updated July 27, 2026

Short answer: Yes — if you own an MSA Advantage-series respirator and your documented air monitoring shows organic vapors as the sole hazard. The MSA 815355 Advantage GMA is an activated-carbon cartridge rated for organic vapor protection, sold in a convenient 2-pack, with a snap-on mount that is only compatible with the Advantage platform. If your hazard assessment also flags particulates or acid gases — common in spray painting, welding support, or acid-adjacent solvent work — step up to the MSA Advantage GMA-P100 or the MSA Advantage GMC before issuing this cartridge to workers.

MSA Safety produces two parallel cartridge platforms: the long-running Comfo series (threaded bayonet mount) and the newer Advantage series (snap-on press-fit mount). The MSA 815355 Advantage GMA is the Advantage platform's entry-level organic vapor cartridge — the same activated-carbon chemistry as the Comfo GMA, repackaged in a snap-on housing for the Advantage 200 LS, Advantage 420, and the Advantage 1000/3000/4000 full-face lineup.

The 815355 is a single-function cartridge: activated carbon sorbent only, no particulate layer. It belongs at the base of the Advantage cartridge stack — the right choice when organic vapors are the only certified hazard in the work environment, and the wrong choice when co-exposures exist. This review covers mount compatibility, protection scope, real-world buy scenarios, a full competitive comparison, and a cost-per-shift analysis to help you decide between the 815355 and the next rung up.

Editorial Verdict: 4.3 / 5

The MSA 815355 Advantage GMA delivers reliable organic vapor protection on the snap-on Advantage platform at a reasonable 2-pack price. It earns its rating for clean NIOSH compliance and easy mount engagement, but loses points against the Comfo GMA on per-cartridge cost — you pay a convenience premium for small-quantity packaging. Buy it when you need OV-only coverage on Advantage respirators; pass if your exposure profile has any particulate or acid gas co-exposure.

Browse the full MSA respirator filters and cartridges collection for the complete Advantage cartridge lineup.

• Industrial painters using solvent-based coatings where air monitoring confirms OV as the only inhalation hazard and no spray mist or particulate is generated at actionable levels
• Solvent degreasing technicians in parts-cleaning operations with MEK, acetone, naphtha, or similar solvents — OV-only exposure profile confirmed by IH sampling
• Coating and varnish applicators in well-ventilated shops where particulate control is handled by engineering controls rather than respiratory PPE
• MRO and maintenance crews who already own Advantage-platform respirators and need a supply of OV cartridges for short-duration adhesive or solvent tasks
• Safety managers standardizing on the Advantage platform who want a tiered stocking strategy: 815355 for OV-only tasks, Advantage GMA-P100 for mixed environments

What the MSA 815355 Advantage GMA does well

Snap-on mount reliability on the Advantage platform

The Advantage cartridge system uses a snap-on bayonet press-fit that is distinct from the threaded bayonet on the Comfo series. The 815355 engages with an audible click on the Advantage 200 LS and Advantage 420 half-masks, as well as the Advantage 1000, 3000, and 4000 full-face models. The mechanical engagement is positive and repeatable, reducing the risk of a cartridge that is "seated but not sealed" — a failure mode more common in threaded-bayonet systems that are over-torqued by field workers.

Proven activated-carbon organic vapor chemistry

The GMA chemistry designation across MSA's cartridge lineup signifies activated carbon formulated specifically for NIOSH OV testing under 42 CFR Part 84 Subpart L. The same core sorbent has been used in MSA's Comfo GMA (SKU 464031) for decades, providing a long field-performance history across solvent degreasing, painting, and coating applications. The 815355 packages that chemistry in the Advantage snap-on housing without reformulation — what changes is the mechanical interface, not the protection capability.

Broad Advantage platform compatibility

A single SKU covers the entire Advantage respirator lineup: the two half-masks (200 LS, 420) and the three full-face models (1000, 3000, 4000). Safety managers standardizing on the Advantage platform can stock one OV cartridge SKU across the whole fleet. Paired with the Advantage P100 low-profile filter, the 815355 also supports combination cartridge configurations on respirators that allow cartridge + prefilter stacking.

NIOSH 42 CFR Part 84 certification baseline

The 815355 carries NIOSH approval under 42 CFR Part 84, which is the federal certification standard for air-purifying respirator cartridges. This approval is mandatory for OSHA 1910.134-compliant respiratory protection programs. Each cartridge is traceable to a NIOSH TC- approval certificate that can be cross-referenced on the NIOSH NPPTL Certified Equipment List.

2-pack convenience for task-specific deployment

The 815355's 2-pack format lowers the entry cost for low-frequency OV tasks. High-volume programs wanting the lowest per-cartridge cost should evaluate the MSA Comfo GMA 464031 (10-pack at the listed price/cartridge) if the respirator fleet supports the Comfo bayonet mount. For Advantage-only programs, the 815355 is the correct choice regardless of quantity.

Full APF compliance under OSHA 1910.134

When used with a properly fit-tested Advantage respirator, the 815355 delivers APF 10 on a half-mask and APF 50 on a full-face respirator per OSHA 29 CFR 1910.134 Appendix B. These are the standard Assigned Protection Factors for all half-mask and full-face air-purifying respirators — the cartridge chemistry does not change the APF, but using a mismatched or non-approved cartridge invalidates the APF claim for the respirator system.

Where the MSA 815355 Advantage GMA falls short

OV-only protection scope limits its application range

The 815355 protects against organic vapors only. It provides zero protection against acid gases (Cl₂, HCl, SO₂, HF), ammonia, particulates, or mercury. This single-chemistry design is the right call for a truly OV-only exposure, but it is the wrong cartridge the moment an IH sampling report flags any co-exposure. Spray painting with atomized pigment, cutting or sanding coated materials, or working adjacent to acid cleaning lines all require a cartridge with a particulate layer at minimum. The correct upgrade path is the MSA Advantage GMA-P100 (815362), which adds a P100 particulate stage to the same OV chemistry.

No end-of-service-life indicator (ESLI)

Like all current MSA Advantage cartridges, the 815355 has no colorimetric or electronic end-of-service-life indicator. Cartridge replacement must be managed through a documented change-schedule program based on OSHA 1910.134(d)(3)(iii) requirements — accounting for concentration, humidity, workload, temperature, and cartridge storage time. Programs that have not established a written change schedule cannot comply with 1910.134 when issuing this cartridge, regardless of how reliable the activated carbon sorbent is.

Higher per-cartridge cost than the Comfo GMA equivalent

The 815355 costs the listed price per cartridge at 2-pack pricing. The Comfo GMA 464031 costs the listed price per cartridge when purchased in a 10-pack — a 28% per-unit cost difference for the same underlying chemistry. This premium is the cost of the Advantage platform's snap-on convenience and smaller pack size. High-volume programs on the Comfo platform have a real cost argument to stay there; programs already committed to Advantage respirators should accept the 815355 price point as a platform choice, not a cartridge-quality difference.

Not compatible with non-Advantage MSA respirators

The snap-on press-fit mount on the 815355 is physically incompatible with the threaded bayonet on the Comfo Classic, Comfo II, Ultra-Twin, and Ultra-Elite respirators. It also does not fit any 3M, Moldex, or other manufacturer's respirators. If your facility has a mixed fleet — some Advantage, some Comfo — you must stock both the 815355 and the Comfo GMA 464031 to cover all respirators, which complicates storeroom management and creates cross-installation risk.

Common questions

Does the MSA 815355 Advantage GMA protect against particulates?

No. The 815355 is an activated-carbon organic vapor cartridge only. It provides no particulate protection. If your exposure assessment includes any airborne particulates — spray mist, dust, fume, or aerosol — you need the MSA 815362 Advantage GMA-P100, which adds a P100 particulate stage to the same organic vapor chemistry.

What respirators is the MSA 815355 Advantage GMA compatible with?

The 815355 is compatible exclusively with MSA Advantage-platform respirators: the Advantage 200 LS, Advantage 420, and the Advantage 1000, 3000, and 4000 full-face models. It is not compatible with MSA Comfo Classic, Comfo II, Ultra-Twin, or Ultra-Elite respirators (which use a threaded bayonet mount), nor with any 3M, Moldex, or other manufacturer respirator.

MSA 815355 Advantage GMA vs. MSA 464031 Comfo GMA — which should I buy?

The chemistry is identical — both are activated-carbon OV-only cartridges. The difference is the mount system. Buy the 815355 if your respirators are Advantage-platform. Buy the Comfo GMA 464031 if your respirators are Comfo-series (Classic, II, Ultra-Twin, Ultra-Elite). Do not attempt to cross-install them — the snap-on and bayonet mounts are physically incompatible. At volume, the Comfo 10-pack at the listed price/cartridge is more cost-efficient; the Advantage 2-pack at the listed price/cartridge is more convenient for low-frequency issuance.

What is the MSA 815355's NIOSH approval class?

The 815355 is approved by NIOSH under 42 CFR Part 84 as an organic vapor (OV) cartridge. The NIOSH OV class covers solvents and organic compounds that are adsorbed by activated carbon, including acetone, MEK, toluene, xylene, naphtha, and many coating solvents. It does not cover acid gases, ammonia, or mercury, which require different sorbent chemistries. Verify the specific TC- approval number on the NIOSH NPPTL Certified Equipment List.

Can I use the MSA 815355 for spray painting?

Spray painting with solvent-based coatings generates both organic vapors and atomized particulates (paint mist). The 815355 OV-only cartridge handles the vapor component but provides no protection against the spray mist. For spray painting, the MSA 815362 Advantage GMA-P100 is the correct cartridge — it combines OV protection with a P100 particulate filter. OSHA 1910.94 and 1910.134 both address spray finishing operations; consult your industrial hygienist for the specific cartridge selection for your coating product and process conditions.

How often should I replace the MSA 815355 Advantage GMA cartridge?

The 815355 has no end-of-service-life indicator. Replacement intervals must be established through a written change-schedule program per OSHA 29 CFR 1910.134(d)(3)(iii). For most industrial OV tasks at or below the PEL, an 8-hour shift-change schedule is common practice. High-concentration environments, elevated humidity (above 85% RH), or elevated temperatures reduce cartridge service life and require shorter change intervals. Review the MSA Technical Data Sheet and consult a Certified Industrial Hygienist (CIH) to establish the program-specific schedule.

Is the MSA 815355 approved for IDLH atmospheres?

No. Air-purifying cartridge respirators — including the 815355 — are never approved for IDLH (immediately dangerous to life or health) atmospheres. IDLH conditions require supplied-air respirators (SAR) or self-contained breathing apparatus (SCBA) per OSHA 1910.134(d)(2). The 815355 is for non-IDLH OV environments only.

What is the APF for the MSA 815355 cartridge?

The Assigned Protection Factor is a property of the respirator/facepiece, not the cartridge chemistry. On an Advantage half-mask (200 LS, 420), the APF is 10 per OSHA 1910.134 Appendix B Table 1 — suitable for airborne concentrations up to 10x the OEL. On an Advantage full-face respirator (1000, 3000, 4000), the APF is 50. The 815355 cartridge must be paired with a properly fit-tested Advantage respirator to achieve these APFs.

Does the MSA 815355 protect against acid gases like chlorine or HCl?

No. Activated carbon sorbent in the 815355 adsorbs organic vapors; it does not capture acid gases such as Cl₂, HCl, SO₂, or HF. For acid gas protection on the Advantage platform, you need the MSA Advantage GMB (815356) for acid-gas-only environments or the MSA Advantage GMC (815357) for combined OV + acid gas environments.

Will the MSA 815355 Advantage GMA fit my MSA Ultra-Elite full-face respirator?

No. The MSA Ultra-Elite uses a bayonet-style cartridge mount from the Comfo series, not the Advantage snap-on system. The 815355 physically cannot be installed on an Ultra-Elite. For Ultra-Elite OV protection, use the Comfo GMA 464031 or the Comfo GMA-P100 (for OV + particulate).

MSA 815355 vs. MSA 815362 Advantage GMA-P100 — what is the listed price per cartridge difference worth?

The 815362 GMA-P100 adds a P100 particulate stage (99.97% filtration) to the identical OV sorbent bed. The per-cartridge premium is the cost of that P100 layer. If your air monitoring definitively excludes particulates, the 815355 is the right cost-optimized choice. In any environment where particulate status is uncertain, the 815362 is the more defensible choice — P100 protection at a modest upcharge prevents a gap in protection that could expose workers and the employer to 1910.134 non-compliance.

Can I stack an N95 prefilter on top of the MSA 815355 OV cartridge?

Yes, on compatible Advantage respirators, the MSA Advantage N95 snap-on prefilter can be used with the GMA cartridge to add N95-level particulate protection. However, this combination adds breathing resistance compared to the integrated GMA-P100 cartridge. For most applications, the 815362 GMA-P100 is the simpler and more consistent solution for OV+particulate protection on the Advantage platform.

What organic vapors does the MSA 815355 Advantage GMA protect against?

The NIOSH OV classification covers a broad range of organic solvents and vapors adsorbed by activated carbon, including but not limited to: acetone, MEK, MIBK, toluene, xylene, benzene, naphtha, mineral spirits, alcohols (methanol, ethanol, isopropanol), chlorinated solvents (dichloromethane, perchloroethylene), and most common coating and adhesive solvents. Refer to the MSA TDS and AIHA WEEL/ACGIH TLV publications for the specific compounds tested in NIOSH cartridge approval. Acetaldehyde and some very low molecular weight or high-vapor-pressure compounds may not be adequately captured — check the NIOSH approval for specific compound coverage.

How does the MSA 815355 Advantage GMA compare to the 3M 6001 OV cartridge?

Both are NIOSH OV-class activated-carbon cartridges at the same APF. The critical difference is the mount system: the 815355 fits only MSA Advantage respirators; the 3M 6001 fits only 3M 6000/7000-series respirators. They are not interchangeable across brands. Choose based on which respirator platform your facility has standardized on, not on cartridge chemistry — both deliver the same OV NIOSH certification class.

Is the MSA 815355 Advantage GMA the right cartridge for solvent degreasing?

It can be, if your industrial hygiene sampling confirms that the only airborne hazard in your degreasing operation is organic vapor at sub-IDLH concentrations, with no co-generated particulate or acid gas. Common degreasing solvents (naphtha, MEK, trichloroethylene, mineral spirits) are typically OV-class compounds well-served by activated carbon. However, many degreasing operations also involve mist or aerosol at the degreasing tank surface — if mist is present, use the 815362 GMA-P100 instead.
