The H2gO Purifier was designed for hikers and campers, travelers, missionaries, Peace Corps volunteers, first responders, disaster relief, and emergency kits. This 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 120,000+ liters (16,000 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.
H2gO GLOBAL
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 240 liters (65 gallons) per battery charge and can be recharged repeatedly via the on-board solar panel or the micro USB port.
The H2gO GLOBAL will supply a family with at least 10 years of safe water (at 40 L or 10 gals per day) for only $0.50 per YEAR in common salt and a weekly recharge.

H2gO PRIME
We designed the H2gO PRIME purifier for water treatment for the US military, based on the EPA Guide Standard & Protocol for Testing Microbiological Water Purifiers. The H2gO PRIME creates a consistent disinfectant dose of 5.0 ppm sodium hypochlorite, twice the dose of the H2gO GLOBAL. It will treat 120 liters (32 gallons) of water per battery charge and can be recharged repeatedly via the on-board solar panel or the micro USB port.
The H2gO PRIME will supply an individual with at least 10 years of safe water (at 16 L or 4 gals per day) using only 1 cup of common salt per YEAR and a weekly recharge.

Comparison of H2gO GLOBAL and H2gO PRIME
Which H2gO Purifier is right for you?
Both H2gO purifiers are the same dimension and weight with the same battery specifications:
- Size: 7”W x 3.625”H x 1.1”D (4.3cm W x 9.2cm H x 2.8cm D)
- Weight: 8 oz (108 g) for the purifier
- Battery: 4-hour USB recharge; 24-hour solar recharge
The H2gO GLOBAL is an ideal device for those who will be treating generally clear water or who are very sensitive to the taste of chlorine in the water. (Note that more turbid water can be treated with a double dose.) The treatment guidelines of 2.5 ppm follow those of the World Health Organization. The largest volume that can be treated with a single dose is 20 liters, equivalent to a 5-gallon bucket.
The H2gO PRIME is an ideal device for those who want maximum disinfection efficacy in a single punch or who will frequently be treating more turbid waters. The treatment guidelines of 5 ppm are based on Environmental Protection Agency standards. The largest volume that can be treated with a single dose is 10 liters.
