TDS meters

Our water filter jugs and dispensers use deionisation to reduce virtually all TDS in minutes, using just gravity - resulting in a purer taste. No flat, boiled flavour here!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, fertilisers and more.

No. The TDS meter measures Total Dissolved Solids, not specific contaminants like lead, PFAS, or bacteria. Think of it as a helpful tool to monitor your filter’s performance. When the reading reaches 6 or higher, it’s time to replace your filter for the best taste and quality.

Your meter reads Total Dissolved Solids (TDS) in your water, measured in parts per million (ppm). It gives you a real-time look at the quality of your water, so you always know when it’s time to change your filter.

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."

Culligan with ZeroWater Technology reduces virtually all total dissolved solids (TDS) from your water, giving you a level of filtration comparable to reverse osmosis or distillation, but with none of the hassle.

ZeroWater Technology versus distilled water

Distillation boils water and collects the steam, leaving most dissolved solids behind, but the process takes hours and requires electricity. Culligan ZeroWater filters use deionisation to reduce virtually all TDS in minutes, using just gravity. The result is similar purity, but with a fresher, more refreshing taste. No flat, boiled flavour here.

ZeroWater Technology versus reverse osmosis (RO)

Like Culligan with ZeroWater Technology filters, RO systems produce highly purified water, but they can be expensive and require installation. Culligan with ZeroWater Technology gives you similar results without the waste, hassle, or plumbing.
