Appearance

The Water Filtration Suit is mainly white in colour, with dark grey patches on the shoulders and around the legs. A network of orange coloured tubing spans the exterior of the suit.

Uses

The Water Filtration Suit conserves and filters the player's bodily fluids, resulting in drinkable Reclaimed Water being added to the inventory, assuming there is space for it. Drinking Reclaimed Water restores 20 H2O points at a cost of -3 Food. The Water Filtration Suit produces Reclaimed Water at a fixed rate of two per day, with a small item popup appearing whenever it does so.

The Water Filtration Suit cannot support the player's water needs single-handedly, as the player loses water at a rate far higher than 40 per in-game day. It does prolong the player's survival in instances where they do not have easy access to water, and can be helpful on long journeys. It is important to have access to food if using Reclaimed Water to supplement water supplies, as otherwise the food penalty can easily result in the player starving to death.

The player uses 1 unit of thirst every 20 seconds. A day/night cycle is 20 minutes. In a day a player will need 60 units of thirst. Since the Water Filtration Suit provides 40 units a day, it effectively reduces the depletion rate to one third. Without any sources of water, the player can survive 1⅔ of a day (33⅓ min) without a Water Filtration Suit and 5 days (100 min) with one.

A Thermoblade is a great way to counteract the food penalty.

Data Bank Entry

The industry standard Water Filtration suit is designed to minimize water loss while exploring hostile environments, by filtering and recycling bodily fluids.

• Reclaimed water is stored in containers for later consumption, normal production rate is 2 bottles per day

Trivia

• Prior to the Living Large Update, the former name for the Water Filtration Suit was the Stillsuit.
• The former name and function comes from Frank Herbert's 1965 novel Dune. The name is a portmanteau of "Distillation" and "Suit". In the novel, the stillsuit is the unique technology of the Fremen -- whom are inhabitants of Arrakis, an arid desert planet, and they use the suit to desalinate and reclaim body moisture and even process waste.
• Previously, the player had to use the Modification Station to upgrade the dive suit into the Water Filtration Suit.
• The PDA Entry mentions a Mk.II variant which can process tears as well, though it is not actually available in the games.
