Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals that linger in the environment and can sometimes be found in water sources. Also called polychlorinated biphenyls, these substances were commonly used in older electrical gear and certain manufacturing applications. Because they break down slowly, PCBs can persist in sediments and waterways for long periods. Nash homeowners typically hear about them through utility notices, community conversations, or private testing of well or tap water.
At the tiny concentrations PCBs usually occur, you won’t be able to detect them by sight, smell, or taste. They can reach drinking water via legacy contamination, disturbed sediments, or runoff that carries pollutants into surface supplies. Even if your Nash tap water looks clear, people often worry about the effects of long-term exposure during cooking, showering, and laundry. A whole-house system treats all the water entering your home, so you protect every faucet and appliance rather than just a single point.
The best single-filter choice for whole-house PCB removal is an activated carbon system, typically using catalytic carbon or a dense carbon block designed for adsorption. PCBs are hydrophobic organic compounds, so they’re effectively captured by carbon media instead of by basic sediment filters. As Nash water flows through the carbon bed, polychlorinated biphenyls can stick to the carbon surface and be reduced before reaching your plumbing. Whole-house carbon filtration also helps lower other organic contaminants that behave similarly.
For reliable performance, a whole-house activated carbon filter must provide adequate contact time and enough media for your home’s peak flow so it can treat water consistently. Many systems use a sediment pre-filter ahead of the carbon to prevent early clogging, while the carbon stage does the heavy lifting for PCBs. Correct sizing and scheduled media or cartridge changes matter because adsorption capacity is finite. Mr. Pure Water can evaluate Nash homes and recommend a properly sized whole-house carbon system to address PCBs at the point your water enters the house.
