Including filter system and high-performance PCBs filter.
PCBs are industrial chemicals that linger in the environment and can sometimes be detected in drinking water. Also called polychlorinated biphenyls, they were commonly used in older electrical gear and some manufacturing applications. Once PCBs enter waterways they break down slowly and can persist at low levels. Athena homeowners usually hear about them through utility notices, neighborhood conversations, or private water testing.
Because PCBs often occur at trace concentrations, you won’t be able to see, smell, or taste them in your tap water. They can get into source waters from past contamination, disturbed sediments, or polluted runoff. Even when Athena’s water looks clear, questions about long‑term exposure around cooking, bathing and laundry are understandable. Treating water at the whole-house level protects every faucet and appliance, not just a single point-of-use.
The best single-filter option for removing PCBs in a whole-house system is a quality activated carbon filter — typically catalytic carbon or carbon block media engineered for strong adsorption. Because PCBs are hydrophobic organic compounds, carbon media trap them more effectively than basic sediment filters. As your home’s water flows through the carbon, polychlorinated biphenyls can cling to the media and be reduced before the water reaches taps around Athena. This carbon stage also helps lower many other organic contaminants that travel on similar pathways.
To work reliably, an activated carbon PCB filter must provide adequate contact time and enough media for your household flow, so it still treats water during peak demand. A sediment pre-filter is often installed ahead of the carbon to prevent premature fouling, while the carbon bed does the main contaminant removal. Correct sizing and regular media or cartridge changes matter because adsorption capacity is finite. Mr. Pure Water can design and size a whole-house carbon system for Athena homes so PCBs are addressed right where water enters your plumbing.
