MSA GME-P100 Multigas / P100 Cartridge for Comfo Respirators — Box of 6

MSA GME-P100 Multigas / P100 Cartridge — Broadest Chemical and Particulate Protection for Comfo Respirators

The MSA GME-P100 Combination Cartridge (SKU 815182) delivers simultaneous NIOSH-approved protection across nine reactive and inorganic gas hazard classes combined with P100 (99.97% efficiency) particulate filtration, making it the most comprehensive single cartridge available for the MSA Comfo half-mask respirator platform. Hazard coverage includes chlorine, sulfur dioxide, chlorine dioxide, hydrogen chloride, hydrogen sulfide, ammonia, methylamine, formaldehyde, and hydrogen fluoride — combined with full-spectrum P100 particulate filtration. It is suited for complex industrial environments, emergency response operations, and facilities where complete hazard characterization is not available in advance.

Construction and Filter Media

The GME-P100 incorporates a multi-layer construction: a P100 particulate filter at the cartridge inlet, followed by a multi-stage chemically impregnated sorbent bed covering the nine NIOSH-approved gas classes. Air passes through the P100 layer first to capture aerosols and particulates, then through the chemical sorbent stages, and exits through the bayonet mount. This arrangement protects the chemical sorbent from particulate fouling and extends chemical service life. The cartridge uses the standard Comfo bayonet mount with quarter-turn tool-free attachment to the Advantage 200 LS, Comfo Classic, and Comfo II respirators.

NIOSH Approval and Compliance

The GME-P100 is NIOSH-approved under 42 CFR Part 84 for combined multigas service (chlorine, SO2, ClO2, HCl, H2S, NH3, methylamine, formaldehyde, HF) and P100 particulate filtration. When used with a properly fitted MSA Comfo half-mask, the system provides an APF of 10 per OSHA 29 CFR 1910.134. The GME-P100 does not include organic vapor (OV) protection — solvents and hydrocarbons require a cartridge with activated carbon OV coverage, such as the GMA-P100 (SKU 815178) or GMC-P100 (SKU 815180).

Performance in Industrial Environments

The GME-P100 is the appropriate default for emergency response and hazmat operations where the complete chemical hazard profile cannot be determined in advance. In complex chemical manufacturing environments with multiple reactive gas streams and particulate co-hazards, the GME-P100 eliminates the need for multiple cartridge selections. Service life is governed by the first sorbent stage to reach breakthrough and by particulate loading of the P100 layer. An objective change schedule accounting for all relevant hazard classes is required; no ESLI is included.

Strengths

• Broadest coverage in the MSA Comfo combination range: nine reactive gas classes plus P100 particulate in a single cartridge
• Eliminates multi-cartridge selection decisions in environments with complex or underdefined chemical hazard profiles
• P100 layer positioned upstream to protect the chemical sorbent from particulate fouling
• Compatible with all MSA Comfo half-mask respirators via the standard bayonet mount

Limitations

• Does not protect against organic vapors (solvents, hydrocarbons) — OV hazards require the GMA-P100 (SKU 815178) or GMC-P100 (SKU 815180)
• Box of 6 at higher per-box cost — may be over-specified for single-class hazard environments
• Multi-sorbent construction may exhibit shorter service life than targeted single-class cartridges in environments with only one chemical class present

Recommended Use Cases

The GME-P100 is suited for hazmat response and emergency operations, complex chemical manufacturing with multiple reactive gas processes and particulate co-hazards, water treatment operations combining chlorine handling and aerosol exposure, and industrial facilities where simplifying cartridge inventory is a priority over optimizing per-class service life.

Verdict

The MSA GME-P100 provides the most comprehensive coverage available in the standard Comfo cartridge range for reactive gas and particulate environments. Facilities primarily facing organic vapor exposure should use the GMA-P100 (SKU 815178) or GMC-P100 (SKU 815180) instead, as the GME-P100 does not include activated carbon OV protection. For reactive gas environments without particulate co-hazards, the standalone GME (SKU 492790) provides the same nine-class chemical coverage at lower cost.
