Top-Notch Filtration​
Using leading patented ceramic technology, and activated carbon, Coldstream water filters remove contaminants from microorganisms and heavy metals to PFAS and microplastics. But don’t just take our word for it, check out the performance data sheets for yourself.
For PFAS and Comprehensive Coverage: Coldstream Ceramic MAX
The Coldstream Stainless Steel Counter Top System and the Under Counter System both utilize the Coldstream Ceramic MAX water filter cartridge. This powerful filter removes a wide range of contaminants to provide comprehensive protection for you and your loved ones. With emerging contaminants like PFAS and microplastics being found in more of U.S. groundwater sources, it becomes essential to safeguard the drinking water in your home. The Ceramic MAX filter provides that protection, allowing you to enjoy clean and safe water, straight form your tap.

- Removes microplastics
- Removes 99.9% of lead, mercury, aluminum, and other heavy metals
- Includes unique warning indicator to signal replacement is needed
- Independently tested and certified to NSF/ANSI standards
- Manufactured 95% plastic-free and compostable
For Fluoride, Taste and Odor: FTO Plus Water Filter Cartridge
Already own a gravity-fed filtration system? The FTO Plus water filter cartridge is the perfect replacement filter for your existing system. The ceramic outer layer provides protection against bacteria while the carbon inner of the filter works to reduce heavy metals and chemicals while also improving the taste and odor of your drinking water.

Why Choose a Coldstream Filter?
Manufactured by KLT Corporation in the UK, transparency, quality, performance, and sustainability are at the heart of Coldstream’s mission.
Transparency
Sharing knowledge and expertise about how Coldstream filters work, is central to Coldstream's mission. The Stainless Steel Over Counter system, and MAX under Counter System, both utilize the ceramic MAX water filter cartridge, while the FTO Plus is it's own unique filter element. Both use ceramic pore technology to filter out particles and microorganisms, while activated carbon works to reduce chemical concentrations, heavy metals, and other contaminants.
Quality
Coldstream filters are manufactured using quality, ethically-sourced materials. Using ceramic material originating from diatomaceous earth, provides a natural alternative to other filters that are made with plastic or synthetic material. All filter elements are 95% plastic-free with the goal of going 100% plastic-free in 2024.
Performance
The World Health Organization (WHO) has published several reports outlining guidelines on safe drinking water, and what constitutes safe levels of particular contaminants. All Coldstream filters undergo rigorous testing to ensure that our filter exceed the quality standards set forth by organizations like the WHO. Beyond that, third-party laboratories are utilized to demonstrate the validity of all of our tests.
Sustainability
We are proud to say that Coldstream filters are manufactured solely using renewable sources of energy. Harnessing the power of wind and solar energy, the production process is zero carbon and highly sustainable. We understand that in the current climate, many brands and businesses make environmental claims to appeal to the heart of many consumers. This is why KLT Corporation, the manufacturer of Coldstream filters is working towards being a Certified B Corporation and achieving circular economy principles.
