MSA Advantage GMC/P100 Respirator Cartridge Overview

The MSA Advantage GMC/P100 is a NIOSH-approved combination cartridge for MSA Advantage respirators that protects against organic vapor and acid gas AND airborne particulate in one unit. The built-in P100 filter captures at least 99.97% of particles, so the MSA Advantage GMC/P100 covers gas plus dust without a separate prefilter. Start with the cartridge selection guide, the organic vapor vs P100 guide and the color chart.

As a Advantage combination cartridge it fits the MSA Advantage 200 LS, 420, 1000, 3200 and 4100, and belongs to the MSA respirator filters and cartridges range. Choose the gas-only GMC if there is no dust; the MSA Advantage GMC/P100 when gas and particulate are both present.

Where the MSA Advantage GMC/P100 Fits in Cartridge Selection

The MSA Advantage GMC/P100 handles organic vapor and acid gas and airborne particulate. If you are weighing gas-only versus combination cartridges, our filter types explained and Comfo vs Advantage guides help you decide.

Who Should Buy the MSA Advantage GMC/P100?

Buy it if your work mixes organic vapor and acid gas with dust or mist on an MSA Advantage facepiece. Choose the gas-only GMC if there is no dust. For a broader gas mix, see the MSA Advantage GME/P100 multi-gas cartridge.

What Does the MSA Advantage GMC/P100 Protect Against?

What the MSA Advantage GMC/P100 Does NOT Protect Against

The MSA Advantage GMC/P100 does not stop ammonia or formaldehyde. For a different gas, match the MSA cartridge to the hazard; for a broad mix use the GME/P100 multi-gas version.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the MSA Advantage GMC/P100 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. A cartridge or filter carries no assigned protection factor of its own — the APF comes from the facepiece it is fitted to: 10 for a half mask, 50 for a full facepiece (OSHA 1910.134 Table 1), which is the number that decides the highest exposure the respirator may legally be worn in. That facepiece must be fit tested before first use and at least annually, and a fit test is specific to one make, model, and size — passing on one mask does not carry over to another. Perform a user seal check every time the respirator is donned, and note that facial hair crossing the sealing surface disqualifies a tight-fitting respirator no matter how well it fit at the last test.

Best Applications
