About ZeroWater
Who are ZeroWater?
ZeroWater designs and supplies kitchen-top water filtration systems, including filter jugs, larger dispensers and replacement filters. These products are typically used in homes, offices and shared spaces as an alternative to bottled water, helping users improve taste while reducing plastic waste.
The range is aimed at people who want a higher level of filtration than standard jug filters provide.
Brand background and expertise
ZeroWater became part of the Culligan family in 2020, combining ZeroWater’s filtration technology with Culligan’s long-established expertise in water treatment. Culligan has over 85 years of experience in water science and service, and the combined group operates globally across domestic, commercial and community water solutions.
In 2025, the brand introduced an updated range of kitchen-top jugs and dispensers under the Culligan with ZeroWater Technology name.
Filtration technology and performance
ZeroWater products use a proprietary five-stage ion exchange filtration system designed to remove up to 99.9% of total dissolved solids (TDS), along with a wide range of contaminants such as lead, heavy metals, pesticides and certain pharmaceuticals.
Each system includes a digital Total Dissolved Solids (TDS) meter, allowing users to measure water quality before and after filtration and to monitor when filters should be replaced.
The filtration performance has been independently tested and certified, including IAPMO certification for the reduction of lead and PFAS (often referred to as “forever chemicals”).
Sustainability and environmental approach
ZeroWater products are designed to reduce reliance on single-use plastic bottles by encouraging refill and reuse. A single filter can replace a large number of plastic bottles over its lifespan, supporting lower household plastic waste.
As part of the Culligan group, the brand has stated commitments around responsible sourcing, ethical operations and reducing environmental impact over time, including emissions monitoring and supplier standards.
Reputation and recognition
ZeroWater is widely known in the water filtration space for its measurable filtration results, particularly its ability to produce very low-TDS water. The inclusion of a digital TDS meter has helped distinguish the brand by allowing users to see filtration performance directly rather than relying on taste alone.
