Versatile Treatment. Superior Performance.

Create The Carbon Block For Your Needs

Custom Formulation

Design your carbon block water filter to suit your requirements. CB Tech can accommodate a broad range of water contaminants at specific degrees of treatment performance.

Contaminant Treatment

Exceptional performance in the treatment of aesthetic and health contaminants, including certified treatment for chlorine, chloramine, VOCs, lead, and Arsenic.

Superior Performance

CB Tech’s superior filtration performance is the result of pioneering development carbon blocks, offering submicron filtration and a high level of chemical adsorption.

Namomesh Technology

CB Tech’s Nanomesh technology offers certified treatment of bacteria and viruses, creating not just a carbon block filter, but a carbon block purifier.

No Chemical Additives

CB Tech carbon block filters do not require chemical additives for water filtration or purification, affording you self-contained, low-maintenance water treatment.

Waste-Free Reduction

CB Tech carbon blocks do not waste water during treatment, allowing effective contaminant reduction in an efficient, environmentally-friendly manner.

NSF certified water filters

NSF Testing and Certification

The NSF Difference

NSF and WQA testing and certification capability verifies the integrity of CB Tech’s high-performance carbon blocks. CB Tech offers certifications for NSF/ANSI Standard 42 (Aesthetic Effects), NSF/ANSI Standard 53 (Health Effects), NSF/ANSI Standard 401 (Emerging Compounds), and NSF Protocol P231 (Bacteria and Viruses).

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.
