Moldex 7367 Organic Vapor Acid Gas P100 Combo Cartridge

Moldex 7367 Overview

The Moldex 7367 is a combination respiratory protection set — one OV+AG cartridge (using the same 7307 chemistry) paired with one 7740 P100 particulate filter — designed to mount on Moldex 7000, 7800, and 9000 series respirators and deliver organic vapor, acid gas, and P100 particulate defense in a single installation. Each bag contains one cartridge and one filter; order two bags to fully equip a half-mask or full-face respirator with matched protection on both ports.

For painters, coaters, and chemical workers who previously had to purchase a Moldex 7307 OV+AG cartridge and a Moldex 7740 P100 filter separately, the 7367 set eliminates the ordering friction and guarantees the correct cartridge-filter pairing every time.

Where the Moldex 7367 Fits in Respirator Selection

Respirator cartridge selection starts with the hazard inventory: what chemical class, at what concentration, and with or without airborne particulates. The 7367 targets the most common industrial combination — solvents or acid mists alongside fine particulates — and covers it with a single set rather than two separate purchases.

If your SDS sheets list organic vapors (aromatic or aliphatic solvents, most VOCs) alongside inorganic acid gases such as hydrogen chloride, chlorine, hydrogen fluoride, or sulfur dioxide, and the work also generates dust, mist, or aerosolized paint particles, the 7367 is engineered for that exact scenario. Our P95 vs R95 vs P100 filter class guide explains why P100 is the right choice whenever oil aerosols are present — which is almost always true in spray finishing environments.

Workers on cartridge change schedules who do not have access to electronic service life indicators can consult our ESLI vs. change-schedule guide for OSHA-compliant approaches to tracking breakthrough. If your hazard is purely particulate with only nuisance-level vapors, review our nuisance relief vs. rated protection guide before selecting this cartridge — you may need only the Moldex 7760 P100 filter with nuisance OV/AG relief instead.

Who Should Buy the Moldex 7367?

What Does the Moldex 7367 Protect Against?

What the Moldex 7367 Does NOT Protect Against

• Ammonia and methylamine: No ammonia sorbent in this cartridge. Use the Moldex 7467 AM+P100 combo.
• Carbon monoxide and other non-organic gases: Activated carbon cartridges do not adsorb CO, CO₂, NO, or similar inorganic gases. No air-purifying respirator is approved for CO above nuisance levels.
• Mercury vapor: Requires a mercury-specific sorbent bed. See our mercury vapor cartridge guide for the correct selection.
• Radioactive or highly toxic (HE-class) particulate: Requires HEPA-class (HE) filtration in a supplied-air or powered air-purifying system, not P100 air-purifying cartridges.
• Asphyxiant gases and vapors: Air-purifying respirators cannot create oxygen where none exists.
• Concentrations above the cartridge's tested service life at the use concentration.

Best Applications for the Moldex 7367

Automotive and Industrial Spray Painting

Spray finishing with solvent-based paints, primers, and clear coats generates simultaneous organic vapor and paint mist exposure. The 7367 addresses both with one set: the OV+AG cartridge captures solvent vapors while the P100 filter intercepts atomized paint particles and oil aerosols from the spray gun. Workers fitting a Moldex 7000 half-mask for spray booth work should order two 7367 sets per worker per fitting.

Chemical Processing and Lab Environments

Facilities handling dilute acid solutions, chlorinated solvents, or mixed organic/inorganic chemical streams frequently encounter both vapor-phase and aerosol-phase hazards simultaneously. The 7367's combined OV+AG chemistry covers the most common chemical classes found in such environments. Workers should maintain a written change-schedule program per their industrial hygiene assessment — this cartridge has no ESLI to indicate saturation.

Fiberglass Fabrication and Resin Work

Open-mold fiberglass layup and resin casting produces styrene or other organic vapor alongside airborne glass fiber particulate. The 7367 provides rated OV protection against styrene vapors with P100 filtration for fibrous particles — the combination required by most fiberglass shop safety programs. Mount on a Moldex half-mask for most fiberglass fabrication tasks.

Battery Manufacturing and Acid Handling

Lead-acid battery work exposes workers to sulfuric acid mist (an acid gas/mist hazard) alongside lead particulate. The 7367's P100 filter addresses lead dust while the AG sorbent handles sulfuric acid mist. For full-face coverage in high-splash battery rooms, pair the 7367 sets with the Moldex 9000 full-face respirator.

Surface Preparation and Coating Removal

Solvent stripping, acid etching, and chemical cleaning operations expose workers to organic solvents, acid vapors, and stripped-coating particulate in the same breathing zone. Rather than stacking a vapor cartridge under a separate P100 filter, the 7367 combo set provides a pre-matched, single-source solution. Review our full Moldex cartridge and filter catalog if your surface prep process involves unusual chemical classes not covered by OV or AG ratings.

Moldex 7367 Pros and Cons

Compatible Moldex Respirators

The Moldex 7367 uses the standard Moldex bayonet/threaded mount and is designed for use exclusively on Moldex-platform respirators. It does not fit any non-Moldex respirator — the bayonet geometry is proprietary to Moldex and is not cross-compatible with 3M, Honeywell North, MSA, or any other brand's respirator body.

Moldex 7367 vs Moldex 7307 + 7740 (Separate Purchase)

The most common decision point is whether to buy the 7367 combo set or purchase the 7307 cartridge and the 7740 P100 filter separately.

Buy verdict: The 7367 combo is the right pick for per-person procurement and field use. The separate 7307+7740 purchase makes more sense for high-volume industrial programs where the cartridge and filter will be replaced on different schedules and storeroom discipline is reliable.

Moldex 7367 Quick Answers

What is included in the Moldex 7367?

Each Moldex 7367 bag contains one OV+AG combination cartridge (using the same chemistry as the 7307) and one 7740 P100 particulate filter. You receive a matched, pre-paired set. Purchase two bags to fully equip a dual-port half-mask or full-face respirator.

Does the Moldex 7367 fit 3M respirators?

No. The Moldex 7367 uses Moldex's proprietary bayonet mount and is not compatible with 3M, Honeywell North, MSA, or any other brand's respirator. It fits only Moldex 7000, 7800, and 9000 series respirators.

Is the Moldex 7367 approved for spray painting?

Yes. The 7367's OV cartridge protects against solvent vapors common in paints and coatings, and the P100 filter captures atomized paint mist including oil-based aerosols. Use it on a properly fit-tested Moldex half-mask or full-face respirator in a spray finishing environment with adequate ventilation.

How often should the Moldex 7367 be replaced?

Replace the 7367 cartridge set according to your site's established change schedule, which must be developed per OSHA 29 CFR 1910.134 based on contaminant type, concentration, and exposure duration. The 7367 has no ESLI, so breakthrough is not visually indicated. Replace the P100 filter portion when breathing resistance increases noticeably or per your site's filter change interval — whichever comes first.

What is the difference between the Moldex 7367 and the 7667?

The Moldex 7367 provides OV+AG+P100 protection without a service life indicator. The 7667 provides multi-gas+P100 protection with Moldex Smart ESLI — a color-change visual indicator that shows remaining service life. Choose the 7667 if your safety program requires visual end-of-service-life indication; choose the 7367 if your program relies on a written change schedule and OV+AG coverage is sufficient for your hazard profile.

Can the Moldex 7367 be used for mold remediation?

The P100 filter in the 7367 provides effective filtration of mold spores (particulate). If the remediation site also involves chemical exposure — such as biocide sprays with solvent carriers or pre-existing VOC contamination — the OV+AG cartridge adds appropriate vapor protection. For pure mold remediation without chemical vapor hazards, a lower-cost P100-only filter may be more appropriate.

How many Moldex 7367 sets do I need per respirator?

Two. A standard Moldex half-mask (7000 series) and full-face respirator (9000 series) have two filter ports — one on each side. Each 7367 bag contains one cartridge+filter set. Order two bags per worker per respirator fitting.

Moldex 7367 Frequently Asked Questions

How many Moldex 7367 sets do I need to complete a half-mask setup?

You need two bags. Each Moldex half-mask — including the 7001, 7002, and 7003 — has two filter ports. Each 7367 bag contains one OV+AG cartridge and one P100 filter for a single port. Purchase two bags to equip both sides of the respirator.

Is the Moldex 7367 suitable for lead paint removal work?

For lead paint removal that also involves solvent-based strippers or acid-based products, the 7367's P100 filter addresses airborne lead particles while the OV+AG cartridge covers chemical vapors. For dry sanding or abrasive removal of lead paint without chemical solvents, a standalone P100 filter may be more cost-effective. Verify your task's full chemical exposure inventory with your industrial hygienist before selecting.

What is the shelf life of the Moldex 7367 before it is opened?

Moldex does not publish a specific shelf life for the 7367 on the product data sheet. Keep cartridges in their original sealed packaging, stored in a cool, dry location away from direct sunlight and reactive chemicals. Inspect the seal before use; do not use cartridges whose packaging has been compromised, as activated carbon begins adsorbing contaminants immediately upon exposure to the ambient atmosphere.

Can the Moldex 7367 be used on the Moldex 9000 series full-face respirator?

Yes. The 9001, 9002, and 9003 full-face respirators use the same Moldex bayonet mount as the 7000 series half-masks. The 7367 combo sets fit both platforms. Order two bags per worker for a complete full-face setup. Full-face respirators also provide eye and face protection against acid splashes, making the 9000+7367 combination appropriate for battery acid and chemical splash environments.

Does the Moldex 7367 require a fit test?

The cartridge itself does not require fit testing, but the respirator it mounts on does. Under OSHA 29 CFR 1910.134, any worker who uses a tight-fitting air-purifying respirator must undergo annual quantitative or qualitative fit testing for their specific facepiece model and size. Fit testing is a requirement of the respirator program, not the cartridge selection.

What acid gases does the Moldex 7367 protect against?

The Moldex 7367 provides NIOSH-rated acid gas protection against common inorganic acid gases including hydrogen chloride (HCl), chlorine (Cl₂), hydrogen fluoride (HF), sulfur dioxide (SO₂), and hydrogen sulfide (H₂S) at concentrations below IDLH. It does not protect against ammonia or organic acid vapors not covered by the OV rating. Consult the Moldex approval documentation for the complete list of test gases and concentrations.

Can I replace just the P100 filter part of the Moldex 7367 set without replacing the cartridge?

No. The 7367 is sold as a matched set and the P100 filter component is not sold separately within this bundle. However, the equivalent standalone filter — the Moldex 7740 P100 filter — is available separately if you wish to replace only the particulate filter while retaining the existing OV+AG cartridge. For high-volume use where the filter and cartridge have different replacement frequencies, purchasing the 7307 and 7740 as separate SKUs may be more economical.

Is the Moldex 7367 approved for hydrogen sulfide (H2S) environments?

The acid gas sorbent in the 7367 provides some protection against low concentrations of H₂S (an acid gas). However, H₂S is also an extremely hazardous gas that can reach IDLH at relatively low concentrations (50 ppm per NIOSH), causes olfactory fatigue at low concentrations (making smell unreliable as a warning), and can be present in oxygen-deficient spaces. H₂S work should be governed by a full confined-space entry program. Do not rely on any air-purifying cartridge as the sole protection strategy in confined spaces or H₂S-generating environments without gas monitoring and emergency egress procedures in place.

What is the price difference between the Moldex 7367 and buying the 7307 and 7740 separately?

For a single worker's full respirator setup (two ports): the 7367 costs $23.24 (2 bags × $11.62). The equivalent separate purchase — two 7307 singles ($8.80 each = $17.60) plus one 7740 pair ($21.19) — totals $38.79 for the same coverage. The 7367 combo is substantially cheaper per setup when one 7307+7740 pairing per port is the goal.

Does Moldex make a version of the 7367 with an ESLI?

Not for OV+AG+P100 in a single set. The Moldex 7667 Multi-Gas+P100 Smart combo includes Moldex Smart ESLI service life indication but covers a broader multi-gas class rather than OV+AG specifically. If visual end-of-service-life indication is a requirement of your safety program, the 7667 is the closest Moldex option.

Can the Moldex 7367 be used for welding fumes?

The P100 filter in the 7367 will capture metal fume particulate. However, welding also generates CO and other gases that activated-carbon OV+AG cartridges do not neutralize. Most welding fume exposure programs focus on particulate control (P100 filter adequate) with engineering controls (ventilation) for gaseous byproducts. If your welding environment also involves chemical solvent vapors or acid gas from flux, the 7367 covers both. For welding fume guidance without solvent exposure, a standalone 7740 P100 filter may be appropriate instead.

Is the Moldex 7367 reusable?

The 7367 set is not reusable indefinitely. The cartridge is a single-use cartridge in the sense that once it has adsorbed to its rated capacity or reached its change-schedule date, it must be replaced. The facepiece respirator it attaches to (the 7000 or 9000 series) is a reusable half-mask or full-face respirator. The cartridge and filter sets (7367 bags) are the consumable components replaced on the established change schedule.
