Water Filtration Machine (Subnautica)

The Water Filtration Machine is a Habitat Compartments module and is constructed by the Habitat Builder. It can only be built on a wall in a Multipurpose Room.

The Water Filtration Machine utilizes Energy from the seabase to desalinate the ocean water. It will slowly produce Salt and Big Filtered Water. The Water Filtration Machine has an internal storage of four items and will stop working once it is filled. When added to a base it will lower the Hull Integrity by 2.0 units.

The Water Filtration Machine uses half a point of Energy per second (taken two or three at a time) and can be powered nonstop with 5 Solar Panels per Water Filtration Machine. Using this setup, a small amount of excess Energy (approximately 30-40) will be leftover by the end of the night and can be used for other base functions. While the machine has no off switch and will constantly produce water, it will stop operating so long as its inventory is full.

It takes about 15 minutes and 40 seconds to finish one unit of Big Filtered Water and 7 minutes and 40 seconds to finish one unit of Salt, but it works on both at the same time.

Data Bank Entry
The filtration system draws water unfit for human consumption from an external source, atomically splits it into its constituent parts and outputs consumable liquid water and salts while disposing of any harmful by-product. It can be built in any compatible habitat module, but has substantial power requirements.
