style=\"color:#ffb74d;\"\u003eWhat respirators does the MSA GMB-P100 fit?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eThe MSA GMB-P100 fits MSA Comfo-platform half-masks that use the proprietary Comfo bayonet mount: the Comfo Classic (Hycar and Silicone versions), the Comfo II, and the Advantage 200 LS. It does not fit MSA Ultra-Twin, Ultra-Elite, or Advantage full-face respirators, which use different cartridge attachment systems.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eIs the GMB-P100 NIOSH-approved?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eYes. The MSA GMB-P100 is NIOSH-approved under 42 CFR Part 84 for combined acid gas and P100 particulate service. The P100 rating certifies a minimum 99.97% filtration efficiency against oil and non-oil-based aerosols. NIOSH approval documentation is available from MSA Safety for compliance recordkeeping purposes.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eHow many cartridges are in a box and what does each cost?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eEach box contains 6 cartridges at a list price of $218.22, which works out to approximately $36.37 per cartridge. The cartridges are sold in pairs — two per respirator — so one box outfits three complete respirator setups.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eDoes the GMB-P100 protect against chlorine gas?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eYes. Chlorine (Cl₂) is classified as an acid gas and falls within the GMB-P100's NIOSH-rated protection scope. The acid gas sorbent bed adsorbs chlorine vapor while the P100 filter layer captures any chlorine mist aerosol. This makes the cartridge a standard choice for water treatment plant operations and chlorination system maintenance. Consult your IH for service life determination.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eCan I use the GMB-P100 for organic vapor exposures?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eNo. The GMB-P100 contains an acid gas sorbent bed and a P100 filter — it has no activated carbon layer for organic vapor adsorption.

Under OSHA 29 CFR 1910.134(d)(3)(iii)(B), facilities must implement a documented cartridge change schedule based on objective data — industrial hygiene air monitoring, manufacturer service life charts, or published exposure modeling. Replace cartridges immediately if odor, taste, or irritation is detected through the facepiece, or per your facility's established change interval, whichever comes first.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eIs the MSA Comfo bayonet compatible with 3M or Moldex respirators?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eNo. The MSA Comfo bayonet mount is proprietary to the MSA Comfo respirator platform and is not interchangeable with 3M bayonet cartridges, Moldex threaded cartridges, or Honeywell North bayonet systems.

style=\"color:#ff9800;\"\u003eMSA GMB-P100 Frequently Asked Questions\u003c\/h2\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eDoes the GMB-P100 work with the MSA Comfo Classic respirator?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eYes. The GMB-P100 is designed specifically for the MSA Comfo platform and mounts directly on the Comfo Classic in both the Hycar and Silicone rubber variants. The Comfo bayonet fitting provides a positive-lock connection. Verify your specific respirator model number against MSA's compatibility chart before placing a bulk order.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eWhat is the difference between the GMB and GMB-P100?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eBoth cartridges protect against acid gases on the MSA Comfo platform, but the GMB-P100 adds a P100 particulate filter layer rated at 99.97% efficiency. The base GMB cartridge is an acid-gas-only cartridge suitable for environments with no significant airborne particulate. The GMB-P100 is required when your exposure assessment identifies both acid gas vapors and respirable dust, metal fumes, or mist aerosols in the same work area.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eCan the GMB-P100 be used for hydrogen sulfide (H₂S)?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eHydrogen sulfide is classified as an acid gas, but standard acid gas cartridges provide limited capacity for H₂S and are not reliably rated for it at high concentrations. MSA's published specifications for the GMB-P100 target chlorine, HCl, SO₂, and HF. For H₂S-specific applications, consult your industrial hygienist and review the MSA GME or GME-P100 multigas cartridges, or contact MSA Safety directly for service life data.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eHow many GMB-P100 cartridges does one respirator require?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eHalf-mask respirators such as the Comfo Classic and Comfo II use two cartridges simultaneously — one on each side of the facepiece. A single box of 6 GMB-P100 cartridges supplies three complete cartridge changes for one respirator. For a five-person crew, you would need approximately four boxes to support one full cartridge change per worker.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eIs the GMB-P100 approved for use in confined spaces?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eAir-purifying respirators are not approved for confined space entry where oxygen deficiency or IDLH concentrations may exist. Confined space entry that falls under OSHA permit-required confined space regulations (29 CFR 1910.146) typically demands atmospheric testing and, where hazardous atmospheres are present, supplied-air equipment. The GMB-P100 may be used for routine above-entry work in acid gas environments but is not a substitute for SCBA in permit-required confined spaces.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eWhat is the shelf life of the MSA GMB-P100 cartridge?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eMSA Safety publishes shelf life data for Comfo series cartridges in their product documentation. Generally, sealed respirator cartridges remain serviceable for five years from the date of manufacture when stored in cool, dry conditions away from direct sunlight and chemical contaminants. Check the lot number and manufacturing date on your specific carton and reference MSA's current shelf life guidance for confirmed figures.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eDoes the P100 rating on the GMB-P100 cover oil-based aerosols?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eYes. The P-class designation in NIOSH's 42 CFR Part 84 rating system indicates that the filter is resistant to oil aerosols — P stands for \"P100 oil-proof\" filtration efficiency. This makes the GMB-P100 suitable for environments with both acid gas vapors and oil-based mists or aerosols, unlike N-class (not oil-resistant) or R-class (oil-resistant, single shift only) filter options.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eCan I use the GMB-P100 on a 3M or Honeywell North respirator?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eNo. The GMB-P100 uses the proprietary MSA Comfo bayonet mount, which is not compatible with 3M bayonet, Honeywell North bayonet, or Moldex threaded connection systems. Attempting to force-fit incompatible cartridges creates a seal failure risk and is a violation of NIOSH approval conditions. Buyers on 3M platforms should review \u003ca href=\"\/collections\/3m-respirator-filters-and-cartridges\" style=\"color:#4fc3f7;\"\u003e3M respirator cartridges\u003c\/a\u003e; buyers on Moldex platforms should review \u003ca href=\"\/collections\/moldex-respirator-cartridges-and-filters\" style=\"color:#4fc3f7;\"\u003eMoldex respirator cartridges\u003c\/a\u003e.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eWhat color is the MSA GMB-P100 cartridge?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eNIOSH assigns color codes to help identify cartridge types: acid gas cartridges carry a white color band, and combination cartridges with P100 particulate protection typically display the characteristic magenta\/purple P100 indicator. The GMB-P100 combines these designations per NIOSH color-coding conventions. See the full \u003ca href=\"\/blogs\/guides\/respirator-cartridge-color-chart\" style=\"color:#4fc3f7;\"\u003ecartridge color-code chart\u003c\/a\u003e for a complete reference across all hazard classes.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eIs the GMB-P100 suitable for chlorine bleach odors in a janitorial setting?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eLow-concentration incidental exposure to bleach vapors in well-ventilated commercial cleaning environments typically does not require respiratory protection beyond engineering controls and good practice. The GMB-P100 is an industrial cartridge rated for meaningful acid gas concentrations. If a facility's IH assessment confirms chlorine levels that require respiratory protection, the GMB-P100 on a properly fitted Comfo respirator is an appropriate choice — but cartridge selection must be driven by air monitoring data, not convenience.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eWhat is the assigned protection factor for a half-mask with the GMB-P100?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eOSHA 29 CFR 1910.134 Table 1 assigns a protection factor of 10 (APF 10) to all negative-pressure half-mask air-purifying respirators, including Comfo Classic and Comfo II configurations with the GMB-P100. This means the half-mask reduces inhaled concentration to 1\/10th of the ambient level, up to 10× the permissible exposure limit. Workers in atmospheres exceeding 10× the PEL require a full-face respirator with an APF of 50.\u003c\/p\u003e\n\n  \u003ch3 style=\"color:#ffb74d;\"\u003eAre there P100-only filter options for Comfo respirators if I don't need acid gas protection?\u003c\/h3\u003e\n  \u003cp style=\"color:#e0e0e0;\"\u003eYes.
