ExtendAir CO2 Absorbent Cartridge

The ExtendAir CO2 Absorbent Cartridge is the preferred scrubber used in the O2ptima and O2ptima CM rebreathers. The ExtendAir cartridge addresses many problems that rebreather divers face with conventional granular absorbent. The greatest advantage of the ExtendAir cartridge is its’ ease-of-use. Scrubber packing takes less than a minute with an ExtendAir cartridge, without any mess. ExtendAir cartridges are sold by the box, which includes four individually-sealed cartridges.
