A light in the cap destroys what’s living in the water — and the bottle.
Boab is a stainless steel bottle with a UV-C light built into the cap. Fill it from any tap, press the cap, and in two minutes the light has destroyed the bacteria and viruses in the water — and on the inside of the bottle. Then it runs again every two hours on its own. A blue ring shows you it’s working. No filter, no cartridges, nothing to replace.
