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. These compounds were commonly used in older electrical equipment and certain manufacturing, and when they make their way into waterways they can remain for long periods. In Holmes Valley we recommend paying attention to utility notices, neighborhood conversations, or independent testing to learn whether PCBs are a concern for your home’s water.
Because PCBs typically occur at very low concentrations, you won’t be able to see, smell, or taste them in tap water. They can enter drinking water through historical contamination, disturbed sediments, or runoff that carries pollutants into surface sources. Even if your Holmes Valley water looks clear, it’s reasonable to consider the possibility of long-term exposure; a whole-house approach treats water used for cooking, bathing, laundry and every other routine in the home, not just a single faucet.
The most effective single-filter choice for PCBs in a whole-house system is a high-quality activated carbon unit—typically catalytic carbon or a dense carbon block media engineered for strong adsorption. PCBs are hydrophobic organic compounds and are best captured by carbon media rather than by simple sediment filters. As Holmes Valley water flows through the carbon bed, polychlorinated biphenyls can cling to the carbon surface, reducing their presence before water reaches your taps, while also lowering other similar organic contaminants.
To work reliably for a Holmes Valley home, an activated carbon PCB filter needs adequate contact time and sufficient media volume to handle your peak flow; pre-filters for sediment are commonly installed ahead of the carbon to prevent early clogging. Correct sizing and scheduled cartridge or media replacement matter because the carbon’s adsorption capacity will eventually be used up. Mr. Pure Water can assess your house and recommend a whole-house carbon system matched to your flow and usage so PCBs are addressed where water enters your plumbing.
