What Does Water Purifier Do Rust?

As the name suggests, a water purifier in Rust purifies salt water. In other words, the in-game purifier turns contaminated water into drinkable. Besides that, it will restore your hydration levels. Moreover, freshwater keep you healthy and alive in the game, as well as in real life.

There are two types of water purifiers in Rust:

  • a simple water purifier;
  • a powered water purifier.

One will help you purify small amounts of salt water in the early game, while the other can help mass produce purified water automatically later on. 

How to Purify Water in Rust?

The simple method to purify water in Rust for beginners is to craft the simple Water Purifier. Here’s how:

Resources you’ll need to gather

  • 10 Cloth
  • 15 Metal Fragments
  • 1 Propane Tank

How to Use It

Once you’ve gathered all the necessary resources, it will take 30 seconds for this water purifier to be crafted.

The first thing you need to know about this item is that it has two inventories. To use it properly, you need to place the salt water inside the tank itself (or the input inventory.)

Then, you will see the bucket (or the output inventory) slowly get filled up with purified water.

Powered Water Purifier Rust Farming

We’re going to walk you through a simple step-by-step process of how to set up a powered water purifier in Rust.

Resources you’ll need to gather

  • Powered Water Purifier Blueprint
  • 300 Metal Fragments
  • 20 Cloth
  • 100 Wood
  • Workbench Level 2

How to Use It

Once you’ve crafted your powered Rust water purifier, you need to insert Salt Water inside one of its two barrels (the input barrel).

Then, it immediately starts converting the Salt Water to Fresh Water. As you can see, it works the same as a normal Water Purifier. However, the Powered Water Purifier can handle a much larger flow and purify larger quantities.

In addition, you can connect this item to a water pump and a water source, like the ocean, and it will start mass producing Fresh Water. This way, you can create a water purification farm in Rust.

How to Place Water Purifier in Rust?

If you gather the right components, you can create an automatic Rust farming system for freshwater by using powered water purifiers as your main component. Before crafting, you should be sure you have enough space to place all the required items.

Here’s how it works: Salt Water goes through a Water Pump and into the Salt Water barrel on the Powered Water Purifier in Rust. Then from this item, the purified water goes straight into a large barrel where more of it is collected.

Tip: You must place the Water Pump in a Salt Water source. (e.g. the ocean)

This way, you get much more water for the same amount of work. Below, you can see the electrical schematics of how to place a water purifier in Rust.

Resources you’ll need to gather

  • Power Source (Battery or Solar Panel) 2x
  • Powered Water Purifier
  • Water Pump
  • Wire Tool
  • Hose Tool
  • Splitter
  • Fluid Switch & Pump 2x
  • Water Barrel

How to Set It Up

Creating a powered water purifier farm in Rust comes in two simple parts. Here’s the step-by-step process:

Part 1

  • Step 1: Connect your first Power Source to the Splitter with some Wire.
  • Step 2: From the Power Out on your Splitter, connect some Wire to the Pump Power connector on your Fluid Switch & Pump. (Don’t connect it on the Toggle connector.)
  • Step 3: Connect some Wire from the Power In on your Water Pump to the Power Out on your Splitter.
  • Step 4: Connect another Wire from the third Power Out on your Splitter into the Power In on the Powered Water Purifier.
  • Step 5: Take the Hose Tool and connect it from the Water Output straight into the Fluid Input on the Fluid Switch & Pump.
  • Step 6: From the Fluid Output on the Fluid Switch & Pump, connect another Hose to the Water In on the Powered Water Purifier.

Part 2

  • Step 1: Take your second Power Source and use the Wire Tool to connect it to the Pump Power on your second Fluid Switch & Pump.
  • Step 2: Connect another Hose from the Water Out on the Powered Water Purifier to the Fluid Input on the new Fluid Switch & Pump.
  • Step 3: Finally, take another Hose and connect it from the Fluid Output to the Water In on your Water Barrel.

How Long Does it Take Water to Purify Rust?

The water purification process starts instantly in Rust. A full 2L water tank will offer fully-purified water in just a few minutes. Bottom line, you won’t have to wait long before you have clean water that’s safe to drink in Rust.

A larger tank of water might take more effort and time to complete. However, you can drink the purified water immediately as it starts pouring. Thus, you don’t have to wait for the tank to fill up entirely.
