Oxygen Filters

Oxygen 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. Oxygen Filters can be crafted from the Backpack or found exploring the planets. Oxygen Filters are already unlocked in the research catalog when starting a new game.

Usage

 * Oxygen Filters, once fabricated from the backpack printer or picked up, will immediately produce Oxygen when untethered, filling the primary backpack tank, and then sequentially filling any connected Small Oxygen Tanks. If all tanks are full then oxygen will be used from the remaining filters.
 * Oxygen Filters hold 4 filters which individually hold 20 seconds of air, for a total of 80 seconds (1 minutes 20 seconds).
 * They will stop working when connected to Tethers or disconnected from the backpack.
 * The blue light turns on when the filters are providing oxygen and turns off when connected to Tethers.

Trivia

 * When disconnected from the backpack, the blue light on the filters will remain in whichever state it was when being disconnected.
 * Filters currently are able to fill 8 tanks of oxygen, essentially giving the player up to 11 minutes of air.
