Carbon block filters are advanced water filtration components crafted by compressing premium coconut shell carbon into a dense, microporous block. This structure maximizes surface area and contact time, enabling the filter to efficiently remove a wide range of contaminants—including chlorine, chlorine byproducts, volatile organic compounds (VOCs), chemicals, tastes, odors, and particulates—while delivering high dirt-holding capacity and maintaining strong performance at elevated flow rates. The hydrophilic carbon in our PCB filters is surface-modified to enhance adsorption of dissolved substances, resulting in cleaner, better-tasting water.

By combining mechanical filtration, physical adsorption, and chemical reactions, these innovative filters excel at removing harmful pollutants and are manufactured using advanced techniques to ensure exceptional quality and consistency. Their high flow rate and exceptional capacity make them ideal for standard under-sink and whole-house filtration applications. 

The PCBX carbon block water filter is designed to effectively remove various contaminants from water, including sediment, chlorine, chlorine byproducts, pesticides, herbicides, PFOS, and volatile organic compounds (VOCs). The models rated at 0.5 nominal microns are also capable of removing most bacteria, cysts, and Giardia.

This filter model has been formulated and tested to eliminate over 95% of VOCs and PFAS from the water supply.

These filters are designed to fit 4.5 × 10-inch or 4.5 × 20-inch systems, which are universally referred to in the water industry as "Big Blue" or "whole-house " housings from leading brands like Watts, Pentek, iSpring, Culligan, EcoPure, APEC Water, and Franklin Water.

Exceptional Performance Water Filter Cartridge
The PCBX2005 is a premium carbon water filter cartridge designed for superior performance in demanding filtration environments. This universal, big blue carbon filter uses a 5-micron carbon block to efficiently capture microplastics and fine particles, even at high flow rates, while maintaining a minimal pressure drop. As an ideal filter for whole-house applications, its advanced chlorine and chemical adsorption capabilities ensure consistently fresh, great-tasting water, free from unwanted odors.


Wide Range of Contaminant Removal
Engineered for maximum contaminant removal, this 20-inch carbon filter cartridge utilizes advanced carbon block technology to effectively reduce chlorine, volatile organic compounds (VOCs), per- and polyfluoroalkyl substances (PFAS), and trihalomethanes (THMs)—common byproducts of chlorination. In addition, it reliably eliminates a wide range of organic chemicals, including pesticides, herbicides, and industrial solvents, ensuring safer and cleaner water for your home or business.

 

Engineered to Eliminate Difficult Contaminants
Crafted with premium activated hydrophilic carbon and advanced binders, this 5-micron carbon block water filter cartridge features a fine-pore structure, zero carbon fines, and superior adsorption capacity. As a result, it removes more than 95% of volatile organic compounds (VOCs) and PFAS, delivering contaminant removal performance that surpasses standard CTO filters.

 

Long-lasting Whole House Filtration
Whole-house filtration demands robust, high-capacity filters that deliver precise contaminant removal without sacrificing water pressure or clogging early. The PCBX line of whole-house filter cartridges is engineered to meet these rigorous requirements, offering outstanding capacity for chlorine, VOCs, and chemical adsorption while maintaining high, consistent flow rates. These cartridges effectively remove chlorine, chemicals, sediment, taste, odors, and fine particulates, ensuring reliable, high-quality water throughout their extended lifespan.
