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 find their way into water supplies. Historically used in electrical equipment and certain manufacturing, these compounds break down slowly and can remain in waterways over time. Grayvik homeowners typically hear about them through utility notices, neighbor conversations, or private testing, since PCBs don’t announce themselves with taste or odor.
Because PCBs are usually present at very low levels, you won’t detect them by sight, smell, or taste in tap water. They can enter drinking sources via past contamination, disturbed sediments, or runoff that carries pollutants into surface waters. Even in our humid subtropical Florida setting, clear water isn’t always proof of absence, so many Grayvik residents prefer a whole-house solution to protect cooking, bathing, laundry and everyday water use—not just a single faucet.
The most effective single-filter choice for whole-house PCB reduction is a high-quality activated carbon filter—typically catalytic carbon or a carbon block—because PCBs are hydrophobic organic compounds that adsorb well to carbon media. As your home’s water flows through the carbon, polychlorinated biphenyls tend to cling to the carbon surface rather than passing through like they would with simple sediment filters. A properly specified whole-house carbon stage also reduces other organic compounds that travel with similar contamination sources.
For reliable PCB reduction in a Grayvik home, the carbon filter must provide adequate contact time and enough media volume for your peak flow, and it’s common to pair sediment pre-filtration upstream to protect the carbon from premature clogging. Adsorption capacity is finite, so routine cartridge or media replacement and correct sizing matter to maintain effectiveness. Mr. Pure Water can assess your house’s flow needs and recommend a whole-house carbon system matched to your plumbing so PCBs are addressed at the point water enters your home.
