Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals that persist in the environment and can sometimes turn up in water supplies. Also called polychlorinated biphenyls, these compounds were commonly used in older electrical equipment and certain manufacturing. Because they break down slowly, PCBs that reach waterways may remain for long periods. In Cox, homeowners typically hear about them from utility notices, neighbors, or private water testing results.
Most often PCBs occur at very low concentrations, so you won’t be able to see, smell, or taste them in tap water. They can reach drinking water through past contamination, disturbed sediments, or runoff that carries pollutants into surface sources. Even when water appears clear in Cox households, questions about long-term exposure and everyday use — cooking, bathing and laundry — are reasonable. Treating water at the point it enters the home helps protect all faucets and appliances, not just one tap.
The best single-filter choice for a whole-house system to reduce PCBs is a high-quality activated carbon filter, typically using catalytic carbon or a carbon block designed for strong adsorption. Because PCBs are hydrophobic organic compounds, they’re more effectively captured by carbon media than by simple sediment filters. As water flows through the carbon, polychlorinated biphenyls adhere to the media and are reduced before reaching your plumbing. A whole-house carbon stage also cuts many other organic contaminants that can accompany PCBs.
To work reliably in a Cox home, an activated carbon PCB filter needs adequate contact time and sufficient media volume for your household flow, with upstream sediment pre-filtration to prevent premature clogging. The carbon stage does the heavy lifting for PCBs, but its adsorption capacity is finite, so correct sizing and scheduled media or cartridge replacement are essential. Mr. Pure Water can design and size a whole-house carbon system for your property so incoming water is treated where it first enters your plumbing.
