Trusted filtration for Legacy ZeroWater systems

Keep your water clean and refreshing with Legacy ZeroWater replacement filters. Featuring 5-stage filtration, these filters are designed to reduce lead, chlorine, mercury, and other dissolved solids that impact taste and quality.

Built for compatibility with legacy ZeroWater systems, each filter is easy to replace and helps ensure reliable, everyday filtration without interruption.

Legacy ZeroWater Technology

Legacy ZeroWater Technology filters were designed for earlier pitchers and dispensers. Newer systems use updated filtration technology, so the two filter types don’t mix and match.

You likely have legacy technology if:

  • Bottom-threaded installation

    The filter screws into the bottom of the upper reservoir.

  • ZeroWater logo

    Your pitcher or dispenser will feature the ZeroWater logo.

  • Removable lid

    The entire lid must be removed to refill your pitcher or dispenser.

FAQs

Total Dissolved Solids (TDS) are organic and non-organic sediments found in water, which contribute to a difference in the taste and appearance of water. Dissolved solids enter our water supply through old piping, run-off from road salts, pesticides, fertilizers and more.

Culligan with ZeroWater Technology removes 99.9% of total dissolved solids, including both unwanted contaminants and trace minerals. Our filters are designed to treat everything equally, reducing harmful elements along with minerals that may be naturally present in tap water.

Most health experts agree that your body gets the minerals it needs from food, not water. And according to the Water Quality Association, low-TDS water is safe to drink and widely used around the world. For more, we encourage users to read the Water Quality Association's article:  “Consumption of Low TDS Water."

The lifespan of your filter depends on your local water quality and how much water your household uses. The best way to know? Use the included TDS meter. When the reading hits 6 or higher and the amber light turns on, it’s time to replace your filter. Don’t wait, past that point, taste and smell can start to change.
