This article is about the Rebreather in Subnautica. Click here for information on this subject in Below Zero.

The Rebreather is a piece of equipment which is crafted using the Fabricator. Its purpose is to negate the Oxygen consumption penalty that occurs when diving below 100m, keeping it at a consistent rate of one unit per second regardless of depth. Its Blueprint is unlocked after crafting a High Capacity O₂ Tank.

For the Rebreather to work, it must be equipped in the head slot of the PDA.
