Purified water is a process, not a single method. It’s any water that meets the U.S. Pharmacopeia’s standard of having fewer than 10 parts per million of dissolved solids. That’s a fancy way of saying: “We kicked out 99.9% of the riffraff.”
Purification can happen through reverse osmosis (squeezing water through a super-tight membrane), carbon filtration (like a Brita on steroids), or even UV light (sunburn for germs). It’s the bouncer who checks IDs, frisks for dirt, and sends bacteria home crying to their mothers.
The best part? Purified water often keeps some beneficial minerals, so it actually tastes like something—unlike distilled, which tastes like a memory of wetness. Think of purified as the cool, slightly less intense cousin who still has a personality.
