Moldex 7467 Respirator Cartridge Overview

The Moldex 7467 is a NIOSH-approved combination cartridge for Moldex respirators that protects against ammonia and methylamine AND airborne particulate in one unit. The built-in P100 filter captures at least 99.97% of particles, so the Moldex 7467 covers gas plus dust without a separate filter. It uses Moldex's semi-rectangular design for lower breathing resistance. Start with the cartridge selection guide, the organic vapor vs P100 guide and the color chart.

As a semi-rectangular combination cartridge the Moldex 7467 belongs to the Moldex respirator cartridges and filters range and fits Moldex 7000 and 7800 series half-mask respirators and 9000 series full-face respirators. Choose the gas-only 7407 if there is no dust.

Where the Moldex 7467 Fits in Cartridge Selection

The Moldex 7467 handles ammonia and methylamine and airborne particulate. If you are weighing gas-only versus combination cartridges, our filter types explained and Moldex combo cartridge guide help you decide.

Who Should Buy the Moldex 7467?

Buy it if your work mixes ammonia and methylamine with dust or mist on a Moldex facepiece. Choose the gas-only 7407 if there is no dust. For a broader gas mix with P100, see the Moldex 7667 multi-gas / P100 SMART cartridge.

What Does the Moldex 7467 Protect Against?

What the Moldex 7467 Does NOT Protect Against

The Moldex 7467 does not stop organic vapor, acid gas or formaldehyde. For a broader gas mix use the 7667 multi-gas / P100; for particulate alone the 7740 P100 filter is enough.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the Moldex 7467 in an oxygen-deficient or IDLH (immediately dangerous to life or health) atmosphere, in unknown concentrations, or against gases with no warning properties — those conditions require a supplied-air or SCBA system, not a cartridge respirator.

Best Applications

Ammonia refrigeration with dust

Anhydrous-ammonia work with airborne particulate.

Fertilizer & cleaning

Ammonia tasks that also raise dust.

Pros & Cons

Moldex 7467 vs Other Moldex Cartridges

Moldex 7467 vs the Alternatives

How it compares to the closest Moldex options:

• 7467 vs 7407: same ammonia protection; the 7467 adds a built-in P100 filter for dust.
• 7467 vs 7667: the 7667 multi-gas / P100 covers a broad mix including ammonia.
• 7467 vs 7740: the 7740 is particulate only; the 7467 adds ammonia gas protection.

Moldex 7467 Quick Answers

Does the Moldex 7467 need a separate filter?

No — the P100 filter is built in; there is no filter or retainer to add.

Does the Moldex 7467 fit Moldex 7000 and 9000 respirators?

Yes — it fits the 7000 series half-mask and 9000 series full-face (and 7800 series).

Is the Moldex 7467 reusable?

Moldex 7467 Frequently Asked Questions

What does the Moldex 7467 protect against?

The 7467 is a ammonia and methylamine / P100 combination cartridge. It captures ammonia and methylamine and filters at least 99.97% of airborne particulate. It does not protect against organic vapor, acid gas or formaldehyde.

Does the Moldex 7467 filter dust?

Yes. The built-in P100 filter captures at least 99.97% of airborne particles, including oil-based mists, so no separate filter is needed.

Which respirators does the Moldex 7467 fit?

It uses the Moldex bayonet connection and fits Moldex 7000 and 7800 series half-mask respirators and 9000 series full-face respirators. It does not fit 3M, Honeywell North or MSA facepieces.

What does P100 mean on the 7467?

P100 is the highest NIOSH particulate rating: oil-proof and at least 99.97% efficient. The 7467 carries a magenta P100 marking alongside its gas-class band.

Is the Moldex 7467 NIOSH-approved?

Yes, under 42 CFR Part 84 for its gases and P100 particulate. Verify against the NIOSH Certified Equipment List.

What is the difference between the 7467 and the 7407?

Both cover the same gas, but the 7467 adds a built-in P100 filter for dust. Choose the gas-only 7407 if there is no particulate.

Does the Moldex 7467 need a separate filter?

No. The P100 particulate filter is built in, so there is no filter or retainer to add.

Is the Moldex 7467 the semi-rectangular design?

Yes — it uses Moldex's semi-rectangular shape for more surface area and lower breathing resistance.

How often should I replace the Moldex 7467?

Replace the gas portion at odor breakthrough, and the cartridge when breathing through the P100 filter becomes noticeably harder.

How is the Moldex 7467 sold?

This listing is a pair (2 cartridges). Use Request a Quote for case pricing.

Is this the genuine Moldex 7467 cartridge?

Yes. WC Safety sells authentic, NIOSH-approved Moldex 7467 cartridges through legitimate supply channels.

How should I store the Moldex 7467?

Store it sealed in its original packaging, away from gases and dust, so neither the gas nor filter service life is used up before use.
