How it works

The FDA requires the TDS level in PURIFIED bottled water to reach 000-010ppm. Culligan ZeroWater is the only filter in its class to achieve this level. Culligan ZeroWater's first layer of filtration, activated carbon and oxidation reduction alloy removes the chlorine taste you are accustom to with tap water.

The Ion Exchange stage removes virtually all dissolved solids that may be left over from public water systems or even leached into your water from piping such as Aluminium, Lead, Zinc, Nitrate and more. Three additional stages are included to remove other contaminants and to ensure your water receives the appropriate amount of treatment time to deliver a "000" reading on your water quality meter.

5 filter stages

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.
