Katadyn Pocket Water Microfilter

The only choice for the outdoors, the makers are so confident of the durability of their Katadyn Pocket Water Microfilter that it comes with a 20 year warranty. Used by explorers, jetsetters and aid workers alike, the ceramic element can be cleaned and used over and over again and produces up to a hundred times more water than most of its competitors and there’s even a gauge that tells you when to change it.
