Water Filtration Machine
The Water Filtration Machine is a utility base part in Subnautica 2 that purifies seawater into large filtered water bottles, providing reliable hydration at the cost of base power.
Quick Info
Description
The Water Filtration Machine solves one of survival's biggest problems: thirst. Installed inside a Multipurpose Room, it slowly purifies seawater into large filtered water bottles that restore a significant amount of hydration. The trade-off is power, it draws 50W while running, so pair it with enough Solar Panels to keep your base grid topped up.
How to Craft
Water Filtration Machines are built with the Habitat Builder. Aim at an interior wall of a Multipurpose Room and select the machine to install it. Gather Titanium from limestone and Copper from limestone or other deposits.
- 1x Titanium
- 1x Copper

What does a Water Filtration Machine do?
It purifies seawater into large filtered water bottles, giving you a reliable source of hydration inside your base. Once running, it frees you from hunting bladder fish or crafting salt-cured water.
How much power does a Water Filtration Machine use?
It consumes 50W of power while running, so make sure your base has enough Solar Panels or other power sources. A single Solar Panel at 75W can cover it, but add more if you run other equipment.
How much does a Water Filtration Machine cost?
Each unit costs 1x Titanium and 1x Copper, crafted with the Habitat Builder inside a Multipurpose Room. Both materials are common from limestone outcrops, so it's an accessible upgrade once you have a powered room.
