Moldex 7200 Respirator Cartridge Overview

The Moldex 7200 is a NIOSH-approved acid gas cartridge for the Moldex bayonet system. It adsorbs chlorine, hydrogen chloride and sulfur dioxide and carries a white (acid gas) band, using the traditional Moldex cartridge design. Start with our guide to choosing a respirator cartridge, confirm the band on the respirator cartridge color chart, and see the Moldex cartridge upgrade guide.

The Moldex 7200 cartridge 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. It is a gas cartridge only — for dust, add a 7740 P100 filter.

Where the Moldex 7200 Fits in Cartridge Selection

Confirm the hazard before the cartridge. The Moldex 7200 handles acid gas gas, not particulate. If you also face dust or mist, our organic vapor vs P100 guide and filter types explained cover when to move to a combination cartridge.

Traditional vs Semi-Rectangular

Moldex makes this protection in two shapes. The traditional 7200 is the traditional cartridge; the semi-rectangular 7307 adds surface area for easier breathing. Both carry the same NIOSH approval; see the Moldex 7000 series guide.

Who Should Buy the Moldex 7200?

Buy it if your exposure is acid gas on a Moldex 7000/7800/9000 facepiece. Choose another cartridge if your hazard differs: for acid gas plus dust add a 7740 P100 filter, and for a broader gas mix see the Moldex 7607 multi-gas SMART cartridge.

What Does the Moldex 7200 Protect Against?

What the Moldex 7200 Does NOT Protect Against

The Moldex 7200 does not capture particulate or organic vapor, ammonia or particulate. For dust, add a 7740 P100 filter; for a different gas, match the Moldex cartridge to the hazard.

No air-purifying cartridge makes a dangerous atmosphere safe. Never use the Moldex 7200 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

Chlorine & treatment

Water treatment and chlorine handling on Moldex respirators.

Plating & etching

Acid baths; add a 7740 P100 filter if aerosol is present.

Pros & Cons

Moldex 7200 vs Other Moldex Cartridges

Moldex 7200 vs the Alternatives

How it compares to the closest Moldex options:

• 7200 vs 7300: the 7300 adds organic-vapor protection to acid gas.
• 7200 vs 7307: for acid gas with lower breathing resistance, the semi-rectangular 7307 also covers organic vapor.
• 7200 vs 7740: the 7740 is P100 particulate only; the 7200 is acid-gas only.
