Filtration Canteen

This canteen holds a quart of water. It removes impurities, salts, microbes, and poisons. It can filter salt water, but not raw sewage or toxic waste. On its own, it adds a +1 (quality) bonus to Survival skill when living off the land; it's also included in survival kits.

One quart can be purified in 30 minutes (TL9), 10 minutes (TL10), three minutes (TL11) or instantly (TL12). The filter must be replaced every 100 quarts at TL9, or 1,000 quarts at TL10; a color change signals when it's time to change. An "exhausted" filter still has a few quarts of capacity, but only the GM knows how many. At TL11-12, the filter is permanent.

The canteen is $180, 1 lb. (empty) or 3 lbs. (full). LC4.
