Oxygen Filters

Description
Filters are a "consumable" item that can be used in a pinch to save your life by providing you with oxygen. They are similar to Power Cells in the way that they work.

Crafting
Filters must be researched, before they appear in your inventory crafting list.

You can craft a filter with one compound.

Usage
A filter only activates if you don't have access to any other oxygen supply, such as tethers or mined oxygen.
