Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals known as polychlorinated biphenyls that persist in the environment and can sometimes be found in water. Historically used in electrical equipment and certain manufacturing, these compounds break down slowly and may linger in waterways or groundwater long after they were released. Harper homeowners typically hear about PCBs through water quality reports, local conversations, or independent testing, and they’re often surprised by how long these chemicals can remain in the environment.
Because PCBs usually occur at very low concentrations, 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 waters. Even if Harper’s tap water appears clear, residents may be concerned about long-term exposure from everyday uses like cooking, bathing, and laundry. Treating water at the whole-house level protects every tap and reduces exposure across all household activities.
The single most effective whole-house filter for PCBs is a high-quality activated carbon unit, typically using catalytic carbon or a carbon block designed for strong adsorption. PCBs are hydrophobic organic compounds, so they bind well to carbon media rather than being removed by basic sediment filters. As water flows through the carbon bed, polychlorinated biphenyls adhere to the carbon surface and are reduced before reaching faucets throughout your Harper home, while the system also helps remove other similar organic contaminants.
To perform reliably in a Harper household, an activated carbon PCB system needs sufficient contact time and enough media volume to handle your peak flow; otherwise adsorption can be incomplete. It’s common to pair a sediment pre-filter upstream to protect the carbon from clogging, with the carbon stage serving as the main treatment for PCBs. Regular maintenance and timely media or cartridge replacement are important because adsorption capacity is finite—Mr. Pure Water can size and install a whole-house carbon system matched to your home to address PCBs at the point where water enters your plumbing.
