5-Stage Advanced Filtration

Our advanced 5-stage technology uses the science of deionization to remove 99.6% of Total Dissolved Solids (TDS) from your drinking water. With Culligan ZeroWater, you’ll be left with nothing but the purest-tasting water.

Stage 1

Mesh Filter Screen

Filtration starts with a mesh filter screen to remove suspended solids.

Stage 2

Foam Distributor

A layer of foam then evenly distributes water in preparation for the next stages.

Stage 3

Oxidation Reduction Alloy

An oxidation reduction alloy and fine filter screen remove organic contaminants.

Stage 4

Ion-Exchange Resin

Water then passes through an ion-exchange resin which absorbs inorganic compounds.

Stage 5

Ultra-Fine Mesh Screen

Finally, water continues through an ultra-fine mesh screen and out of the filter.

Zero compromise. Zero doubt.

Worried about what's in your water? Culligan ZeroWater removes guesswork so you can drink with confidence. All our pitchers and dispensers are equipped with a Total Dissolved Solids (TDS) meter, so you always know the level of TDS in your water and when it's time to replace your filter.
