Culligan ZeroWater Replacement Filter - 1 Pack

The same quality you know from ZeroWater, now backed by Culligan's resources

While standard filters only reduce a handful of contaminants, Culligan with ZeroWater Technology uses advanced deionisation, a process that targets virtually all total dissolved solids (TDS) in your water. From minerals and metals to salts and inorganic compounds, our filters reduce the stuff you don't want, leaving behind water that tastes crisper and clean. Our filters use coal-based activated carbon mixed with KDF (a copper-zinc blend) and a mixed bed of ion exchange resin in a BPA-free housing. Together, they work to reduce a wide range of contaminants, so all you taste is clean, better water.

Here's what's happening behind the scenes: As water flows through the filter, it's pulled through a carefully engineered sequence of filtration materials, each one designed to tackle a specific type of contaminant. Larger particles get trapped first. Then, organic materials like chlorine and herbicides are reduced. After that, the magic of ion exchange begins, where unwanted ions (like lead, nitrate, and heavy metals) are captured and replaced with harmless ones. What's left is clean, safer, better-tasting water with virtually no dissolved solids.

What are total dissolved solids?

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.

What's new about the latest Culligan with ZeroWater Technology filters?

Culligan with ZeroWater Technology water filter replacements are certified to reduce over 25 contaminants, including forever chemicals (total PFAS), pharmaceuticals, and heavy metals. To see the difference for yourself, explore our updated performance data sheet.

How do our water filters compare to other filtration processes?

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 vs 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 vs 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.

How often should I change my filter?

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.
