This Pure purification bottle works without power or chemicals. Just fill it with dirty water, plunge the water as if it was a coffee maker, then sterilize by winding for 90 seconds to power up a UV lamp. Apparently this combo is enough to remove 99.9% of bacteria and other nasties in the water. Concept at the moment, but let’s hope it gets to production.
The outer chamber of the water bottle is to be filled with dirty water from a lake, stream or puddle. The inner chamber plunges through the outer chamber, filtering water particles as small as four microns. Once the water is made free from sediments, it is further sterilized for 90 seconds using a wind-up ultraviolet bulb.
