Does the price of bottled water predict how clean it is?

What's actually in it

Bottled water can pick up bisphenols, phthalates, and other endocrine disruptors from three places: the source water, the plastic bottle, and the cap liner. Premium brands often use the same plastic packaging as bargain brands, so the leaching is similar.

Some "premium" labels are actually filtered tap water with extra minerals. The bottle is doing most of the chemical work.

What the research says

A 2026 study in Anal Chim Acta tested dozens of bottled waters across price points using a high-resolution lab method. The team checked dozens of endocrine-disrupting chemicals at once. Price was a poor predictor of cleanliness. The bottle material and where the water came from mattered more.

Glass-bottled waters were the cleanest. PET plastic bottles, regardless of price, all leached at least a little.

Don't pay for fancy bottled water as a health move. A carbon block or reverse osmosis filter at home gives cleaner water for less. If you do want bottled, pick glass.
