The Air Canister (also known as Air Tank) is an item that is used to refill the rebreather. It was added in update v0.14 of The Forest.


To replace the current tank, simply press Left Mouse Button on a new tank. This will only fill the oxygen bar back to 300, however, as the meter will never go above 300 seconds, meaning remaining air from the previous canister is lost. Air canisters are needed to progress the game as some locations cannot be reached without extended diving, for instance in Cave 3 - Wet Cave or Cave 5 - Submerged Cave. A single air canister holds 300 seconds of air. It is possible to finish game on a speed run with only one air canister.

Currently, the player can hold up to 4 air canisters in the inventory.


Air canisters can be found on the yacht or in caves, most often in locations near a deep pool of water. There are many in Cave 5, where the rebreather is located.
