style=\"color:#ffb74d;\"\u003eIs the Moldex 7407 sold as a single cartridge or a pair?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7407 is sold as a single cartridge — one cartridge per bag. This distinguishes it from the \u003ca href=\"\/products\/moldex-7400-ammonia-methylamine-respirator-cartridge\" style=\"color:#4fc3f7;\"\u003eMoldex 7400\u003c\/a\u003e, which is sold as a two-cartridge pair. If you need to replace both cartridges on a half-mask respirator, add two units of the 7407 to your cart, or purchase the 7400 pair.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eWhich Moldex respirator series accepts the 7407 cartridge?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7407 is compatible with the Moldex 7000 series half-mask, the Moldex 7800 series half-mask, and the Moldex 9000 series full-face respirator. All three platforms use Moldex's standard bayonet twist-lock mount. Shop the \u003ca href=\"\/collections\/moldex-half-mask-respirator\" style=\"color:#4fc3f7;\"\u003eMoldex half-mask collection\u003c\/a\u003e or \u003ca href=\"\/collections\/moldex-full-face-respirators\" style=\"color:#4fc3f7;\"\u003eMoldex full-face respirator collection\u003c\/a\u003e to find a compatible facepiece.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eDoes the Moldex 7407 protect against chlorine or acid gases?\u003c\/h3\u003e\n\u003cp\u003eNo. The Moldex 7407 targets alkaline gases only (ammonia and methylamine). Chlorine and acid gases require an acid gas cartridge such as the \u003ca href=\"\/products\/moldex-7200-acid-gas-respirator-cartridge\" style=\"color:#4fc3f7;\"\u003eMoldex 7200 acid gas pair\u003c\/a\u003e. Attempting to use the 7407 for chlorine or acid gas exposure will not provide rated protection.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eDo I need an ESLI if I use the Moldex 7407?\u003c\/h3\u003e\n\u003cp\u003eThe 7407 does not include an ESLI. Without an ESLI, OSHA 29 CFR 1910.134 requires your respiratory protection program to include a written cartridge change schedule established by an industrial hygienist or equivalent qualified person, based on objective information about the contaminant concentration and cartridge service life. Review the \u003ca href=\"\/blogs\/guides\/respirator-cartridge-esli-guide\" style=\"color:#4fc3f7;\"\u003eESLI guide\u003c\/a\u003e for program compliance details.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eCan the Moldex 7407 be used in a full-face respirator for ammonia?\u003c\/h3\u003e\n\u003cp\u003eYes. The Moldex 7407 is compatible with the \u003ca href=\"\/products\/moldex-9000-series-full-face-respirator-9001-9002-9003\" style=\"color:#4fc3f7;\"\u003eMoldex 9000 series full-face respirator ($226.90)\u003c\/a\u003e. A full-face respirator adds eye and face protection in addition to respiratory protection — recommended at higher ammonia concentrations where mucous membrane and eye irritation is a concern.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eWhat is the shelf life of the Moldex 7407 before opening?\u003c\/h3\u003e\n\u003cp\u003eMoldex recommends storing cartridges in the original sealed packaging in a cool, dry location away from contaminants. Sealed cartridges have a manufacturer-specified shelf life of five years from the date of manufacture. Once opened and exposed to ambient air or contaminants, the cartridge service life is governed by your written change schedule — not the shelf-life clock.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eIs the Moldex 7407 approved for use under OSHA's respiratory protection standard?\u003c\/h3\u003e\n\u003cp\u003eYes. The Moldex 7407 is NIOSH-approved, which is the approval required for use in OSHA-regulated respiratory protection programs under 29 CFR 1910.134. Your program must also include medical evaluation, fit testing, training, and a written change schedule per 1910.134(d)(3)(iii) since the 7407 does not have an ESLI.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eHow does the Moldex 7407's chemical mechanism work?\u003c\/h3\u003e\n\u003cp\u003eThe 7407 uses an acid-impregnated adsorbent material. When ammonia (a basic alkaline gas) passes through the cartridge media, it chemically reacts with the acid impregnant and is neutralized before reaching the facepiece inlet. This acid-base neutralization is distinct from the physical adsorption used in activated carbon organic vapor cartridges, which is why the two cartridge types are not interchangeable.\u003c\/p\u003e\n\n\u003ch3 style=\"color:#ffb74d;\"\u003eCan I add a P100 filter to the Moldex 7407 for dust protection?\u003c\/h3\u003e\n\u003cp\u003eThe Moldex 7407 is not designed as a combination cartridge-filter system and does not have a pre-filter adapter.

The Moldex 7407 fits only Moldex 7000\/7800\/9000 respirators; the 3M 6004 fits only 3M 6000\/7000 series respirators.
