Pure is a water bottle designed for adventure tourists and world travelers that filters and sterilizes water from any source within two minutes. Pure contains two chambers. Dirty water is scooped up from a lake, stream or dirty puddle by the outer chamber. The inner chamber is then plunged through it, filtering water particles as small as four microns. Once filtered, the water is sterilized by a wind-up ultraviolet bulb.
