Katadyn MyBottle Purifier Bottle

It doesn't look like much. That's the point. The Katadyn MyBottle Purifier is simple, but it gets the job done so well that it's the only EPA registered bottle purification system available. Katadyn uses 3 Stage Virustat purification technology with activated carbon to remove bacteria like giardia, viruses like ebola, and cysts bleah. The MyBottle Purifier is compact and lightweight, so it's perfect for camping, hiking, and travel to third world countries.
