How Does Culligan with ZeroWater Technology Work for Users?

Culligan with ZeroWater Technology brings together 85 years of water science and a five-stage filtration system designed to reduce dissolved solids with precision. Every jug and dispenser includes a built-in TDS meter that shows the level of dissolved solids in parts per million (ppm). This simple reading helps you see the difference between filtered and unfiltered water at home, giving you a clear view of how your filter is performing.

Our range is independently certified by the International Association of Plumbing and Mechanical Officials (IAPMO). This certification confirms the system’s ability to reduce specific contaminants, including lead, total PFAS, and selected pharmaceuticals. The verified reduction percentages for each substance are listed in our official performance certifications.

In this guide, you’ll see how the five-stage system works, why dissolved solids are measured with a TDS meter, and how each element of the design contributes to cleaner-tasting water you can trust.

The New Standard for Cleaner, Proven-Pure Water at Home

Culligan with ZeroWater Technology combines decades of Culligan water science with a five-stage filtration design built for today’s households. The system reduces dissolved solids and is independently certified to reduce specific contaminants, giving you a clearer view of what your water contains and how your filter performs.

The result is water that tastes crisp and looks clear. Each product undergoes independent verification through IAPMO, which confirms reductions across 28 listed contaminants, including lead and total PFAS. You can find the exact reduction percentages in our performance certifications. The Drinking Water Inspectorate also continues to monitor substances such as PFAS as research develops, helping consumers stay informed about water quality in the UK.

See the Truth in Every Pour with Live TDS Readings

Every jug and dispenser in the Culligan with ZeroWater Technology range includes a built-in TDS meter. This simple tool shows the level of dissolved solids in parts per million (ppm), helping you compare your tap water with your filtered water at a glance.

When the reading reaches zero, it indicates that dissolved solids have been reduced, giving you a clear, instant view of how your filter is performing. The meter measures salts, minerals, and other ions that affect taste and appearance. It does not detect contaminants.

"We want people to feel confident about the water they drink. Tools like the TDS meter give users greater visibility over dissolved solids in their water and support more informed choices at home."

— Kathy Chi Thurber, Global President Consumer Products, Culligan International.

This focus on clarity helps households understand their readings with confidence. For those interested in upgrading their day-to-day drinking water, our jugs, dispensers, and filters are designed for straightforward use and easy visibility.

How Our Five-Stage System Delivers Cleaner-Tasting Water

The five-stage filtration process is at the heart of how Culligan with ZeroWater Technology works. Each stage plays a specific role in reducing dissolved solids and improving taste, giving you water that looks clear and feels refreshing to drink.

Here’s how the stages work together:

• Stage 1: Sediment filtration helps capture larger particles found in tap water
• Stage 2: Activated carbon reduces chlorine taste and odour and targets selected organics that influence flavour
• Stage 3: Ion exchange reduces dissolved salts, minerals, and metals, which affect taste and the overall ppm reading.
• Stages 4 & 5: These final layers help refine clarity and support a crisp, clean-tasting finish.

Replacement filters are available and produced under strict quality controls. The built-in LED indicator on your jug or dispenser shows when it’s time for a filter change, helping you maintain consistent performance with ease.

Debunking Water Filter Myths with Facts

It’s easy to assume that all water filters work in the same way. In reality, the method and certification behind each system influence how effectively it improves your everyday drinking water. Standard sediment or carbon filters mainly focus on taste and odour, while Culligan with ZeroWater Technology also reduces dissolved solids and is independently certified to reduce specific contaminants.

The DWI’s 2024 report shows that drinking water in England and Wales meets 99.97% of regulatory standards. As research develops, the DWI continues to monitor emerging substances such as microplastics to help households stay informed about water quality.

Another common belief is that bottled water is always the cleaner option. However, research shared by BBC News in 2024 highlighted the presence of microplastics in bottled water across the world. Choosing a reusable, certified filtration system at home helps reduce plastic waste and supports a crisp, refreshing taste without relying on single-use bottles.

Trusted by Science, Backed by Certification

Every Culligan with ZeroWater Technology pitcher and dispenser is independently certified by IAPMO. This verification confirms the system’s published reduction rates for specific contaminants, giving users clear and reliable information about how their filter performs.

Global organisations such as the World Health Organization continue to update guidance on drinking water quality as research develops. These evolving standards help shape the wider understanding of water quality around the world, supporting households in making informed choices.

By sharing verified data and keeping our performance information transparent, we help users feel confident in their filtration system. Each certified figure reflects a tested outcome, offering clarity and reassurance with every pour.

Simple, Seamless, Everyday Filtration You Can Rely On

Culligan with ZeroWater Technology is designed to make cleaner-tasting water easy to enjoy every day. Each jug and dispenser focuses on comfort and practicality – from the ergonomic handle and drip-free spout to the secure, fully sealed lid that helps prevent spills.

A built-in LED indicator helps you know when it’s time to replace the filter, removing the guesswork from routine maintenance and supporting consistent performance with minimal effort.

These design choices reflect our focus on user wellbeing and sustainability. Choosing a reusable jug over bottled water helps reduce waste while giving households the crisp, refreshing taste they enjoy. For many, it’s a simple shift that supports better hydration habits and a lower environmental footprint.
