Design Specifications

The H2gO Purifier is charged via solar panel or USB connection and a brine solution is mixed with the addition of salt (each bottle of brine holds ten applications). The brine is poured into the device’s electrolytic cell chamber. A water volume is selected and the device is turned on. An electrolytic process generates the disinfectant in 15 seconds to 5 minutes (depending on the selected volume). Once complete, the solution is mixed with the water to be treated. Instructions require 30 minutes before consuming.

Compliance with regulations

This product claims to meet the requirements for the Center of Disease Control (CDC) Safe Water System. However, to meet disinfection of protozoa requirements, the solution must mix with water for 4 hours (instructions state 30 minutes).

Evaluation methods

The WHO evaluation of H2gO Purifier consisted of a review of existing data on the product’s performance against bacteria and viruses only. Results stated: “In general, the existing evidence suggests that disinfection by chlorine alone or mixed oxidants is ineffective against Cryptosporidium oocysts at concentrations that would be within taste and odor thresholds and contact times reasonably reflective of field use. Although some experimental data were submitted on the product’s performance against protozoan cysts including Cryptosporidium oocysts, they were based on high doses and long contact times (up to four hours). These data were therefore not considered in the review as in practice the recommended contact time is 30 min and achieving longer times would require considerable user education.”
