Here’s the one-liner: Distilled water is a type of purified water, but not all purified water is distilled. Think of it like squares and rectangles. All squares are rectangles, but not all rectangles are squares. Distilled is the overachiever that went through a fancy steam party.
Purified water, on the other hand, is the whole umbrella term. It means the water has been physically treated to remove impurities. Distillation is just one way to get that done—like using a sledgehammer to crack a nut.
