NIOSH-rated ammonia and methylamine protection

These green Comfo chemical combination cartridges carry a NIOSH rating for ammonia and methylamine. They are designed for use with MSA Comfo twin-cartridge series respirators and attach via a threaded connection. The pack contains ten cartridges for workplace respiratory protection.

Air-purifying design with threaded connection

Each cartridge functions as an air-purifying respirator element that filters specific contaminants. The threaded connection ensures a secure fit to compatible Comfo series facepieces. No power source or active components are involved, so operation is silent and produces no heat.

Ten-pack for Comfo twin-cartridge respirators

The package supplies ten cartridges, matching the twin-cartridge requirement for five complete respirator setups. They are compatible only with MSA Comfo series facepieces using the threaded interface. Buyers needing cartridges for other respirator brands or different contaminant ratings should select alternative products.

Questions about this item

How do I install the cartridges on my MSA Comfo Twin-Cartridge respirator?

Align the threads on each cartridge with the facepiece ports and turn clockwise until hand-tight; the step users often miss is performing a positive and negative pressure seal check before entering the contaminated area.

When should I replace the 464033 cartridges?

Replace them immediately if breathing resistance increases, you detect ammonia or methylamine odour, or the end-of-service-life indicator triggers; otherwise follow your written respiratory-protection programme schedule.

What concentration limit applies to ammonia when using these green cartridges?

NIOSH approves them for ammonia and methylamine up to the maximum use concentration defined by your respiratory-protection programme and applicable exposure limits; do not exceed the cartridge capacity.
