Including filter system and high-performance PCBs filter.
Polychlorinated biphenyls, commonly called PCBs, are industrial chemicals that can linger in the environment and occasionally turn up in water sources. They were used in older electrical equipment and various manufacturing processes, and because they break down slowly they can persist in soil and waterways. Campbell homeowners typically first hear about PCBs through utility notices, community conversations, or private water testing, and they often want straightforward ways to protect household water.
PCBs are usually found at very low concentrations, so you can’t rely on sight, smell, or taste to detect them in tap water. These contaminants can reach drinking water from legacy pollution, disturbed sediments, or runoff that carries pollutants into streams and reservoirs. Even in Campbell’s humid subtropical climate, when water appears clear it can still carry trace organic compounds—so homeowners often choose a whole-house strategy to protect water used for cooking, bathing, laundry and everyday needs rather than treating a single faucet.
The most effective single-filter option for whole-house PCB removal is a high-quality activated carbon system—typically catalytic carbon or a dense carbon block—because PCBs are hydrophobic organic compounds that adsorb well to carbon media. Unlike basic sediment filters, carbon captures these compounds as water flows through the media, reducing polychlorinated biphenyls before water reaches your plumbing. A properly selected whole-house carbon filter also helps lower other organic contaminants that behave similarly, improving overall water quality for Campbell homes.
To be effective in a whole-house application, an activated carbon PCB filter needs sufficient media volume and contact time matched to your home’s peak flow, and it’s common to include a sediment pre-filter upstream to protect the carbon from early fouling. Over time the carbon’s adsorption capacity will be spent, so correct sizing and regular cartridge or media replacement are key to consistent performance. Mr. Pure Water can evaluate your Campbell property and recommend a whole-house carbon system sized for your flow so PCBs are addressed where water enters your plumbing.
