This unique water bottle has a built-in filtration system which allows its modest 16 oz (500 ml) capacity to be refilled in 30 seconds with bacterially or chemically tainted water. Special features minimize the risk of contaminating the purified drinking water during all modes of use.
Whether on a hike in the wilderness or living in a city where the public water is not drinkable, this Personal Water Sytem is equally indispensible.
