Grayl Bottle: One-Piece Water Purification in 15 Seconds

While water purification has come a long way, and you've got your choice of pocket-sized, one-piece water filters (like the Lifestraw) and larger, more intricate systems. But one drawback all these typical systems have in common, is that they are separate from your water bottle, thus requiring you to carry more than one item and requiring more effort to properly filter water. The Grayl bottle, however, seeks to simplify the process and streamline everything down into one piece, for simple, one-step water purification.
