Summary

This purified water product includes added minerals like calcium chloride and sodium bicarbonate, which enhance its mineral content and contribute to hydration. However, the use of municipal water as a source and the potential for microplastic contamination from packaging slightly detract from its overall purity and safety. The product is minimally processed, but the lack of transparency regarding PFAS testing and packaging materials could be improved for a higher rating.
