How is ZeroWater different from other filter systems?Updated 2 months ago

5-stage ion exchange vs. standard carbon filters

Most water filter jugs and pitchers use a simple activated carbon filter. Carbon filters are good at improving taste and removing chlorine, but they leave behind a significant amount of dissolved solids (TDS) — minerals, salts, metals, and other contaminants.

ZeroWater uses a 5-stage ion exchange filtration system that removes 99–100% of dissolved solids, bringing your filtered water to a TDS reading of 000. No other pour-through filter brand consistently achieves this.

How ZeroWater compares

  • ZeroWater (5-stage ion exchange): Removes 99–100% TDS, including heavy metals, fluoride, nitrates, lead, chromium, and hundreds of other contaminants. TDS reads 000.
  • Standard carbon filter (e.g. Brita): Primarily removes chlorine and improves taste. Leaves most dissolved solids. TDS reduced by ~20–40%.
  • Reverse osmosis (RO): Also highly effective, but requires installation under the sink and wastes water in the filtration process.
  • Bottled water: Variable TDS depending on source. Expensive and environmentally costly.

Proven by independent testing

ZeroWater is NSF/ANSI certified for the reduction of lead and chromium. Full performance data and certification details are available in our certification article.

The included TDS meter

Every ZeroWater pitcher comes with a free TDS meter so you can verify your filter is working and monitor when to put in a new one. No other filter brand includes this level of transparency.
