The Moldex 7667 set includes the Multi-Gas Smart cartridge, which has a built-in color-change End-of-Service-Life Indicator (ESLI). The indicator window changes color as the activated carbon sorbent approaches saturation. This visual signal replaces the need for a mandatory written change-out schedule in most OSHA respiratory protection programs that require change schedules when ESLI is not available.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eHow many Moldex 7667 sets do I need for one respirator?\u003c\/h3\u003e\n\u003cp\u003eYou need two Moldex 7667 sets per respirator. Each bag contains one Smart cartridge and one P100 filter — enough for one side of a half-mask or full-face respirator. A complete respirator requires two cartridges and two filters (one per port), so order two 7667 sets per worker per replacement cycle.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eWhat respirators is the Moldex 7667 compatible with?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7667 is compatible with Moldex 7000 series half-mask respirators (7001, 7002, 7003), the Moldex 7800 series half-mask, and the Moldex 9000 series full-face respirators (9001, 9002, 9003). It is not compatible with any non-Moldex respirator — 3M, Honeywell North, MSA, Scott, and other brands use different bayonet mount systems.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eWhat gases does the Moldex 7667 protect against?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7667 Multi-Gas Smart cartridge is NIOSH-rated for organic vapors (OV) and acid gases (AG) in combination — the same chemistry as the 7607 single cartridge. It does not protect against ammonia, methylamine, mercury vapor, formaldehyde at rated concentrations, or carbon monoxide. Confirm your specific exposure compounds against the multi-gas rating before use.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eWhat is the difference between the Moldex 7667 cartridge and the 7740 P100 filter?\u003c\/h3\u003e\n\u003cp\u003eThe 7667 set contains two components: the Multi-Gas Smart cartridge handles gas and vapor adsorption, while the 7740 P100 filter handles particulate capture. They work together when assembled on a compatible Moldex respirator — the P100 filter typically attaches to the outside of the cartridge. The ESLI indicator is on the cartridge only; the P100 filter is replaced based on physical condition, breathing resistance, or end of shift.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eIs the Moldex 7667 NIOSH approved?\u003c\/h3\u003e\n\u003cp\u003eYes. The Moldex 7667 combo set — comprising the Multi-Gas Smart cartridge and the 7740 P100 filter — uses NIOSH-approved components. The 7740 P100 filter carries the P100 particulate approval, and the Smart cartridge carries the multi-gas OV\/AG approval. Verify that your respiratory protection program references the current NIOSH approval number for your purchased lot.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eCan the Moldex 7667 be used for spray painting?\u003c\/h3\u003e\n\u003cp\u003eYes, for spray painting applications involving solvent-based paints. The Multi-Gas Smart cartridge addresses organic vapor solvents, and the P100 filter captures atomized paint particles. Verify that your specific paint system's SDS lists hazard constituents within the OV+AG rating. For water-based paints without significant VOC content, a P100-only filter may suffice — the 7667 is appropriate when solvent vapors are confirmed in the exposure profile.\u003c\/p\u003e\n\n\u003c!--

crew?\u003c\/h3\u003e\n\u003cp\u003eOrder four Moldex 7667 sets for a two-person crew — two sets per worker, since each bag equips one side of the respirator. If your crew replaces cartridges weekly, multiply the weekly quantity by your stocking interval. Buying two sets per person in the same order ensures matching cartridge and filter replacement cycles on both sides of each respirator.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eCan I use a Moldex 7667 with a 3M half-mask respirator?\u003c\/h3\u003e\n\u003cp\u003eNo. The Moldex 7667 uses a Moldex-specific bayonet mount. It is physically incompatible with 3M, Honeywell North, MSA, and all other brands' respirators. Attempting to modify or force-fit Moldex cartridges onto non-Moldex facepieces voids approval and creates an unsafe condition. If you use a 3M facepiece, the comparable multi-gas P100 combination option is the \u003ca href=\"\/blogs\/guides\/best-3m-respirator-cartridges\" style=\"color:#4fc3f7;\"\u003e3M 60926 or equivalent from the 3M 60900 series\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eWhen should I replace the Moldex 7667 cartridge vs the P100 filter?\u003c\/h3\u003e\n\u003cp\u003eReplace the Smart cartridge when the ESLI window shows a color change indicating saturation — or immediately at any sign of odor or taste breakthrough. Replace the 7740 P100 filter when it is physically damaged, shows visible contamination, causes increased breathing resistance, or at the end of your shift in heavy particulate environments. The two components have independent replacement triggers and may not need replacement at the same time.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eDoes the Moldex 7667 require a written change-out schedule?\u003c\/h3\u003e\n\u003cp\u003eIn most OSHA-compliant respiratory protection programs, no written change-out schedule is required for the cartridge component when ESLI is present and functioning. OSHA 29 CFR 1910.134 Appendix B2 allows ESLI-equipped cartridges to use the indicator as the replacement criterion. Confirm with your industrial hygienist that the ESLI is appropriate for your specific contaminant concentrations and that the indicator is reliable under your exposure conditions.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eIs the Moldex 7667 appropriate for spray polyurethane foam (SPF) insulation applications?\u003c\/h3\u003e\n\u003cp\u003eSpray polyurethane foam applications involve isocyanate vapors and particulate spray mist. The Moldex 7667's OV+AG+P100 profile provides relevant coverage, but isocyanate-specific protection requirements often mandate higher assigned protection factors and respirator selection based on air monitoring data. Consult your safety data sheet and a qualified industrial hygienist — isocyanate applications are frequently outside the scope of standard OV-rated cartridges at roof-off or enclosed spray concentrations.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eWhat is the difference between the Moldex 7607 cartridge and the cartridge in the 7667 set?\u003c\/h3\u003e\n\u003cp\u003eThey use the same chemistry. The cartridge in the 7667 combo set is the 7607 Multi-Gas Smart cartridge — the identical unit sold individually at $6.65 as the \u003ca href=\"\/products\/moldex-7607-multi-gas-vapor-smart-respirator-cartridge\" style=\"color:#4fc3f7;\"\u003eMoldex 7607\u003c\/a\u003e. The 7667 set bundles that cartridge with the 7740 P100 filter in one bag for convenience. If you only need cartridge replacements (your P100 filters are still serviceable), order the 7607 directly to avoid purchasing filters you do not yet need.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eHow do I verify the ESLI on the Moldex 7667 Smart cartridge is functioning before each use?\u003c\/h3\u003e\n\u003cp\u003eBefore each use, inspect the ESLI indicator window on the Smart cartridge. The indicator should appear in its pre-use baseline color — refer to the Moldex product insert for the specific starting color. If the indicator window already shows a color change or partial change before the cartridge has been used, do not use that cartridge. Store unused cartridges in the original sealed packaging away from heat and chemical vapors to preserve ESLI accuracy.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eDoes the Moldex 7667 protect against welding fumes?\u003c\/h3\u003e\n\u003cp\u003eThe P100 filter component captures metal particulates and fumes generated during welding. However, welding also produces metal vapors (manganese, hexavalent chromium, lead) and gases (ozone, nitrogen oxides) that may require specific cartridge chemistry beyond the standard OV+AG multi-gas profile. For welding applications, verify your exposure assessment covers all generated contaminants — the \u003ca href=\"\/blogs\/guides\/best-honeywell-north-cartridge-for-welding-fumes\" style=\"color:#4fc3f7;\"\u003ewelding fume cartridge selection guide\u003c\/a\u003e provides a cross-brand breakdown of this decision.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eCan the Moldex 7667 be used for asbestos abatement?\u003c\/h3\u003e\n\u003cp\u003eAsbestos abatement regulations under OSHA 29 CFR 1926.1101 specify respirator requirements based on exposure action level and regulation requirements — P100 filtration is required for asbestos fiber capture, and the 7667's P100 filter meets that particulate requirement. However, asbestos abatement work also has facepiece type requirements (half-mask vs full-face vs PAPR) that depend on measured or predicted fiber concentrations. Confirm with your industrial hygienist and your asbestos abatement contractor's respiratory protection program before use.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eIs the Moldex 7667 available in a pair (two sets in one package)?\u003c\/h3\u003e\n\u003cp\u003eNo. The Moldex 7667 is sold as a single set — one Smart cartridge and one P100 filter — per bag at $18.50.
