3. Nestle Pure Life
The story: Nestle owns 64 different brands of water, from Perrier to Poland Spring, but we tested its most popular: Pure Life. It's classified as purified water, which means it comes from a well or municipal source and is then carbon filtered, softened, demineralized, re-mineralized, and disinfected with ultraviolet light and ozone.
Tasting notes: A clean taste, with no trace of minerals at all. Neutral in flavor. If you're a marathon runner, this would be a great choice. It quenches in a very direct and pleasing way.
