Oxygen Filters

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. Filters can be crafted from the Backpack once Researched.

Usage

 * Filters, once fabricated from the backpack printer, will immediately produce Oxygen to fill any connected Small Oxygen Tanks starting with the primary backpack tank, and then sequentially filling any secondary Tanks.
 * A stack of filters holds 4 filters which individually hold 160 seconds of air, for a total of 640 seconds (10 minutes 40 seconds).
 * When attached to tethers, Filters will not decay while in your inventory.

Trivia

 * Though whether it is a bug or not is uncertain, filters decay while attached to the Backpack whether or not Oxygen is completely full, reducing their effective Oxygen output to 20~ seconds per each visible filter subdivision. Consequently, the only known method at the present time to get the full complement of Oxygen is to carry a Filter in the air as one walks around so that it isn't plugged in, and to only wear it when Oxygen is <100%.
