Pure vs Spring Water: What's the Difference and Which Is Better?

Which is better: filtered tap water or spring water?

They come from different places and are processed differently. This guide compares them and where a Berkey fits — municipally treated tap water only.

What’s the Difference?

Filtered tap water starts as city water, then goes through a home filter to reduce chlorine, metals, and other leftover chemicals.

Spring water is bottled from a spring or similar source and processed at a plant. Rocks do not replace a lab test or a home filter.

Filtered Tap Water

A gravity system such as the Big Berkey can reduce chlorine, lead, pesticides, and PFOA. Taste usually improves. Hydration still depends on drinking enough water. See Mayo Clinic on dehydration.

Spring Water

It can contain calcium and magnesium. Alkaline marketing is a separate claim. See a general note on minerals.

Bottles vs Home Filtering

Both spring and “purified” bottled water can contain microplastics. Filtering city tap water at home avoids most of that plastic.

The Berkey Water Filter System

Use it on municipally treated tap water. It reduces pesticides, PFOA, chlorine, lead, and other chemicals. See countertop filter reasons.

Sizes range from Travel Berkey to Big Berkey. Travel size is for packing tap water on the road — not untreated creek water.
