Carbon Block Technology

CB Tech brand drinking water carbon block filtration systems are world-renowned for their cost-efficiency and efficacy, effectively reducing the quantities of most drinking water contaminants with minimal energy expenditure. Arsenic V, pesticides, herbicides, disinfection by-products, heavy metals, cysts, particulates, chloramine and chlorine are just a few examples of what CB Tech’s carbon block water filters can handle.
The system works by using multiple filtration technologies to target the broadest range of contaminants. While a simple filtration system using a single filtration method can effectively target one type of contamination, it fails to filter other contamination types. By combining electrokinetic adsorption and physical adsorption with mechanical filtration in a compact carbon structure, CB Tech carbon block water filters can reduce the quantity of most contaminants with minimal water waste and electricity usage.
CB Tech further reinforces the efficacy of our products with over 45 years of manufacturing experience, rigorous NSF testing and certification, and a continuing commitment to the highest quality standards. Our company will continue to develop industry-leading solutions to new water contamination concerns well into the future.
