Do a blind taste test with your friends. Pour tap water in one cup and RO water in another. Watch their faces contort. They’ll say the tap water “tastes like something.” The RO water? “Tastes like nothing.” That’s the point.
Pure water has zero flavor. It’s a blank canvas for your taste buds. Suddenly, your lemonade tastes more lemony. Your tea tastes more teary. It’s a sensory upgrade.
