The H2Observe water bottle contains a state-of-the-art sensor that measures Total Dissolved Solids. In other words: the purity of the water. When you fill the bottle from any source, you’ll see an immediate indication of risks and impurities. And you’ll contribute real-time purity data to our online map, for all to see.
