The lithium hydroxide
cartridges are of a larger diameter as compared to the much more common
Extend-air slaked calcium hydroxide units. The LiOH cartridges are MUCH
more expensive with a proportionally extended duration time. As a
by-product, they produce a lot of heat. In addition to the downside of
the cost, exposure to water makes them flammable/explosive. The other
cartridges can be acquired through many SCUBA shops.

ExtendAir scrubber cartridge
Just a
note...Lithium Hydroxide canisters were aboard my submarine in case of
emergencies. I would assume that the navy did extensive research and found
these to be the best purchase for the limited space
available.
