Yes — when your hazard assessment documents both ammonia (or methylamine) and respirable particulates, the MSA 815181 GMD-P100 is the correct single-cartridge answer on the Comfo platform. It is the only MSA GM-series cartridge that pairs the dedicated NH₃/methylamine sorbent with an integrated…
Yes — for Comfo-platform users who need NIOSH-approved protection against organic vapors, acid gases, and airborne particulates in a single cartridge. The MSA 815180 GMC-P100 is the triple-combination workhorse of the MSA GM-series lineup, and at $7.75 per cartridge it delivers more protection per…
Yes — for facilities running MSA Comfo platform respirators in environments where acid gases and respirable particulates co-exist, the MSA 815179 GMB-P100 is the single-cartridge answer. It stacks ≥99.97% P100 particulate filtration on top of full acid gas sorbent coverage (Cl₂, HCl, SO₂, HF, H₂S)…
Yes — for most industrial painters, automotive refinishers, and coatings workers, the MSA 815178 GMA-P100 is the correct Comfo-platform cartridge. It covers the two most common co-occurring inhalation hazards in those trades — organic vapors and particulate — in a single NIOSH-approved cartridge on…
Yes — if your exposure profile includes tritium or nuclear fuel cycle work, the MSA GMT is the only MSA Comfo-platform cartridge engineered with a tritium-impregnated sorbent bed. It delivers the same nine-gas inorganic protection as the MSA GME, then adds a specialized sorbent layer no other…
Yes — when your hazard assessment documents two or more inorganic reactive gases and no organic vapor or particulate co-exposure. The MSA 492790 GME covers nine inorganic and reactive gases — chlorine, sulfur dioxide, chlorine dioxide, hydrogen chloride, hydrogen sulfide, ammonia, methylamine…
Yes — if your documented hazard combines organic vapors with acid gases (chlorine, HCl, SO₂, or HF) and your respirator uses the MSA GM-series bayonet mount. The MSA 464046 GMC is the cost-efficient dual-class choice on the Comfo platform when particulate co-exposure is absent. Upgrade to the MSA…
Yes — the MSA 464033 GMD is the specification-correct Comfo-platform cartridge for environments where the documented primary hazard is ammonia (NH₃) or methylamine (CH₃NH₂) vapor without particulate co-exposure. It is the only dedicated ammonia/methylamine-only cartridge in the MSA GM-series…
Yes — if your exposure profile is purely acid gas (chlorine, hydrogen chloride, sulfur dioxide, hydrogen fluoride, or hydrogen sulfide) and you are running MSA Comfo platform respirators. The MSA 464032 GMB delivers focused acid-gas-only NIOSH protection at a lower per-cartridge cost than combo…
Yes — if your exposure profile is organic vapors only and you're already running the MSA Comfo platform. The MSA 464031 GMA is a cost-effective, NIOSH-approved OV cartridge that delivers solid activated-carbon protection for painters, parts cleaners, and solvent handlers. The key qualification: it…
Yes — if you weld, grind, work in a foundry, or perform any hot-work operation that generates sparks or weld spatter, the MSA 10153412 SparkFoe P100 is the correct P100 filter for your Comfo-platform respirator. The SparkFoe's ESD (electrostatic dissipating) coating and flame-resistant outer cover…
Combination cartridges — assemblies that handle both gas/vapor and particulate hazards in one unit — represent the most demanding tier of respiratory protection. They are selected when the hazard profile includes both chemical vapors and aerosols simultaneously: spray painting with solvent-based…
