Salt, water, and a little electricity — that's all the H2gO needs to make safe drinking water. Designed by Aqua Research, the H2gO is a pocket-sized chlorine disinfectant generator that uses electrolysis to turn common salt into a powerful sterilizing solution, letting you treat water almost anywhere with no consumables to run out of. It's WHO-certified for basic household water treatment: a single dose meets treatment standards for viruses and bacteria, and multiple doses inactivate protozoa like Giardia and Cryptosporidium. This collection brings together the H2gO device and everything that supports it —kits, enhanced brine bottles, the H2gO Caddy, tethers, chlorine test strips, and quick-start Water Data Cards. Recharge by USB-C or the built-in solar panel, and pair with a power bank to stay running in the field. Filter your water first for the best results, then disinfect with the H2gO.
