Here’s the kicker: both are extremely pure, but distilled water is the overachiever. It removes nearly 100% of dissolved solids, while purified water hovers around 99%.
That 1% difference means purified water may still hold trace minerals like calcium or magnesium. Distilled? Nada. It’s so pure, scientists use it in labs so their experiments don’t get sassy with minerals.
But unless you’re mixing rocket fuel or cloning a sheep, that 1% is mostly irrelevant for daily drinking. Your kidneys don’t file complaints about a missing magnesium ion. They’re busy, okay?
