Purified water is the umbrella term for any water that’s been treated to remove impurities. It’s a big category with many members.
Distillation is one method. But there’s also reverse osmosis, deionization, and carbon filtration. Each of these takes a slightly different route to clean water city.
The standard? Purified water must have less than 10 parts per million of dissolved solids. That’s a fancy way of saying “very, very clean.”
The Reverse Osmosis Champ
Most store-bought “purified” water uses reverse osmosis. It forces water through a super-fine membrane that blocks almost everything else.
This method leaves in a few minerals—like a polite bouncer at a club. It keeps the bad stuff out but lets the good flavors in.
The result? Water that tastes crisp and clean without that “I’ve been boiled to death” vibe. It’s the friendly cousin.
