H2gO Purifier

This H2gO Purifier weighs only 3.8 ounces (108 grams), fits in your pocket, and is very simple and easy to use. It will treat anywhere from 1 liter (1 quart)up to 20 liters (5 gallons) of water with just a couple of button clicks. It automatically calculates the correct dose for the volume selected, so there is no dosing to calculate. It keeps stored water safe to drink with a lifetime capacity of 60,000 to 124,000+ liters (24,000 to 32,000+ gallons), depending on the model selected. It is inexpensive to purchase and virtually free to operate, with no maintenance, no spare parts, and no consumables (other than common salt), making it truly sustainable.


We designed this purifier for the developing world which means it meets World Health Organization (WHO) standards as defined in the Household Water Treatment Scheme (HWTS). The Global purifier creates a consistent disinfectant dose of 2.5 ppm sodium hypochlorite. It will treat 300 liters (75 gallons) per battery charge and can be recharged repeatedly via the on-board solar panel or the micro USB port.
