Summary

This purified water product includes added minerals like calcium chloride and sodium bicarbonate, which enhance taste and provide some health benefits. However, the water is sourced from a municipal supply, which typically involves more processing compared to natural sources like spring or aquifer water. The lack of transparency regarding PFAS testing and potential microplastic presence in packaging could also impact its overall rating.
