Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals — also called polychlorinated biphenyls — that persist in the environment and can sometimes be detected in water supplies. They were commonly used in older electrical equipment and in various manufacturing processes, and when they reach waterways they tend to break down very slowly. In Mission Bay, homeowners usually hear about them through utility notices, community conversations, or private testing, since these compounds can remain at low concentrations long after initial contamination.
Because PCBs often occur at very low concentrations, you won’t be able to see, taste, or smell them in tap water. They can get into drinking water via historical contamination, disturbed sediments, or runoff that carries pollutants into surface waters. Even with clear water coming from the tap, concerns about long-term exposure for family use are valid. A whole-house system installed at the point where water enters your Mission Bay home treats water for cooking, bathing, laundry and all daily uses — not just a single faucet.
The single most effective whole-house filter for reducing PCBs is a high-quality activated carbon system, typically using catalytic carbon or a carbon block designed for strong adsorption. PCBs are hydrophobic organic compounds, so they adhere well to carbon media rather than being removed by basic sediment filters. As your Mission Bay water flows through the carbon bed, polychlorinated biphenyls can bind to the carbon surface and be reduced before water reaches fixtures, while the carbon stage also helps lower other similar organic contaminants.
To work reliably in a whole-house installation, an activated carbon PCB filter needs sufficient contact time and enough media for your home’s peak flow, so the system can treat water consistently. A sediment pre-filter upstream is commonly used to protect the carbon from premature clogging, but the carbon stage is the main component for PCB removal. Correct sizing and regular media or cartridge replacement matter because adsorption capacity is finite. Mr. Pure Water can assess Mission Bay homes and recommend a whole-house carbon system sized and maintained to address PCBs at your main water entry.
