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.
