The lithium hydroxide canister was designed as a replaceable filter for the lunar module environmental control system (ECS). The ECS provided cooling, water and breathable oxygen for the astronauts’ suits and cabin. To maintain a safe pure-oxygen environment, the canisters contained lithium hydroxide (LiOH) and charcoal and a debris trap. The LiOH within the canister absorbed carbon dioxide, the charcoal eliminated odors.

This unit was found in the collection and was presumably provided by the manufacturer or NASA along with additional Lunar Module artifacts.
