Water Filtration Machine (Subnautica)

The Water Filtration Machine is a Habitat Compartments module that gives the player a stable and consistent supply of water and salt. It can be constructed with the Habitat Builder and placed on a wall in a Multipurpose Room.

Use
The Water Filtration Machine utilizes Energy from the Seabase to desalinate the ocean water, producing Salt and Large Filtered Water. It takes about 15 minutes and 40 seconds to produce one Large Filtered Water and 7 minutes and 40 seconds to produce one Salt. The Water Filtration Machine uses 0.85 points of Energy per second, or 51 Energy per minute (taken two or three at a time), and thus can be powered nonstop with four Solar Panels above 100m depth or almost nonstop with one Bioreactor.

When added to a base, the Water Filtration Machine will lower the Hull Integrity by 2.0 units.

The Water Filtration Machine can store two pieces of salt and two bottles of water. This means that if the Player takes out the water but leaves the salt inside, it will continue to generate water but not generate any more salt. It will stop working once its inventory is filled.

The Water Filtration Machine can be built above water but will produce no salt and will produce water at 1/8th of the speed below water.

If powering the Water Filtration Machine with a consumable energy source such as the Bioreactor, note that each Large Filtered Water takes 799 energy to produce. This means that the Water Filtration Machine will consume 1,598 energy when left unattended.
