A Carbon Dioxide Scrubber is an item used to clean carbon dioxide from the air. The rate at which it depletes

depends on how many modules it must clear of carbon dioxide, and on how many scrubbers there are. When a Carbon Dioxide Scrubber is depleted it can be recharged by placing it into the empty slot of a powered Oxygen Garden.


  • Similar to the Oxygen Tank, the Carbon Dioxide Scrubbers' depletion rate is guarded by the number of scrubbers.
  • A station prioritise carbon dioxide scrubbers over Oxygen Gardens when both of them exists in the same stations. Therefore, the Scrubber will still be used up even when dozens of oxygen gardens are docked alongside it.
