Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals that persist in the environment and can turn up in water supplies long after their use. Also called polychlorinated biphenyls, they were commonly used in older electrical equipment and some manufacturing. Because they break down slowly, PCBs can remain in sediments and waterways for years. Leonia homeowners typically hear about them from utility notices, community conversations, or private water tests, and want clear, practical steps to reduce potential exposure at home.
PCBs usually occur at very low concentrations, so you won’t detect them by sight, smell, or taste in tap water. They can enter drinking water through legacy contamination, disturbed sediments, or runoff that carries pollutants into surface sources. Even when Leonia’s water appears clean, residents may worry about long-term exposure during everyday activities. Treating water at the point it enters your house gives you protection for cooking, bathing, laundry and all household uses—not just a single faucet.
The most effective single-filter solution for PCBs in a whole-house system is a quality activated carbon filter, typically using catalytic carbon or a carbon block designed for strong adsorption. Because PCBs are hydrophobic organic compounds, they adhere well to carbon media rather than being trapped by simple sediment filters. As Leonia water flows through the carbon bed, polychlorinated biphenyls can stick to the carbon surface and be reduced before reaching your taps. A whole-house carbon system also helps lower other similar organic contaminants that can travel with PCBs.
To work reliably for a Leonia home, an activated carbon PCB filter needs sufficient contact time and enough media volume to handle your household flow, especially during peak use. It’s common to add a sediment pre-filter upstream to protect the carbon from early clogging, while the carbon stage does the main contaminant removal. Proper sizing and scheduled media or cartridge replacement are essential because adsorption capacity is finite. Mr. Pure Water can evaluate your home’s needs and match a whole-house carbon system so PCBs are addressed at the point where water enters your plumbing.
