A breathing bag apparatus and simulator is disclosed that has a circuitous and continuous tube within its bag(s) communicating outside air from an inlet filter and carbon-dioxide-conversion canister to the inhalation fixture of the user's facemask. A permanent carbon-monoxide-conversion cylinder forms part of the path of the tube within the bag(s). The cylinder uses porous ceramic pellets to host a coating of platinum as its catalytic noble metal.
