Pitcher & Dispenser Replacement Filters

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.

To see the difference for yourself, explore our updated performance data sheet.

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 deionization 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 flavor 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.

Culligan with ZeroWater Technology filters are certified to reduce over 25 contaminants, including forever chemicals (total PFAS), pharmaceuticals, and heavy metals. For the full list of what we reduce, see our performance results here.
