Moldex 7607 Respirator Cartridge Overview

The Moldex 7607 is a NIOSH-approved multi-gas cartridge for the Moldex bayonet system. It adsorbs organic vapor, acid gas, ammonia, methylamine and formaldehyde and carries a olive (multi-gas) band, using Moldex's semi-rectangular design, which adds filter surface area for lower breathing resistance and better comfort. It is a Moldex SMART cartridge with a color-changing end-of-service-life indicator (ESLI) that shows when to change out. 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 7607 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 or use the 7667.

Where the Moldex 7607 Fits in Cartridge Selection

Confirm the hazard before the cartridge. The Moldex 7607 handles multi-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 semi-rectangular 7607 is the lower-resistance semi-rectangular cartridge with extra surface area. Both carry the same NIOSH approval; see the Moldex 7000 series guide.

Who Should Buy the Moldex 7607?

Buy it if your exposure is multi-gas on a Moldex 7000/7800/9000 facepiece. Choose another cartridge if your hazard differs: for multi-gas plus dust use the 7667, and for a broader gas mix see the Moldex 7607 multi-gas SMART cartridge.

What Does the Moldex 7607 Protect Against?

What the Moldex 7607 Does NOT Protect Against

The Moldex 7607 does not capture particulate or gases outside its approved list. 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 7607 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

Maintenance & response

Mixed or unknown gases; the SMART indicator times change-out and the semi-rectangular shape eases breathing.

Labs

Broad gas mix; for dust use the 7667.

• 7607 vs 7307: the 7607 adds ammonia and formaldehyde plus the SMART end-of-service indicator.

What color band is the Moldex 7607?

The 7607 carries a olive (multi-gas) band; confirm it on the cartridge color chart before use.
