Survival Straw
Survival Straw - Complete Water Purification System

And here.

The Survival Straw is not a filter! It is a highly efficient water purification system that destroys harmful bacteria and viruses that exist in most sources of water. Unlike a typical filter which attempts to trap impurities, the Survival Straw eliminates them.

A single Survival Straw can process over 5,000 gallons (This is a claim by the manufacturer that is not verified) - that's a lifetime of pure water. Compare this to a typical carbon filter which has to be replaced about 30 days after initial use.
