For backcountry trips, travel abroad, or a home emergency kit, the SteriPEN water purifier is easy, fast, lightweight, and exceeds EPA standards for water purification. Eliminate 99.99% of bacteria using UV light, a technology that has been available since the 19th century, but is only recently being utilized in handheld devices affordable to the general public. No set up, no clean up, and no pumping, the SteriPEN Adventurer purifies 16 oz. of water in less than a minute. Simply push a button to activate and stir until the light turns off.
