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 show up in water. These compounds were commonly used in older electrical gear and industrial processes, and when they enter waterways they can be slow to break down. In Dennet, homeowners typically hear about PCB concerns from utility notices, neighborhood conversations, or private testing, and understanding what they are is the first step toward deciding whether treatment is needed.
Because PCBs are usually present at very low concentrations, you won't be able to detect them by sight, smell, or taste in your tap water. They can reach drinking supplies through past contamination, disturbed sediments, or runoff that carries pollutants into surface waters. Even if Dennet water looks clear, families often worry about long-term exposure in everyday activities — cooking, bathing, and laundering — which is why a whole-house solution treats every outlet, not just a single faucet.
The best single-filter option for a whole-house system to address PCBs is high-quality activated carbon — typically catalytic carbon or carbon block designed for strong adsorption. PCBs are hydrophobic organic molecules, so they bind effectively to carbon media rather than being removed by simple sediment filters. As Dennet water flows through the carbon bed, polychlorinated biphenyls adhere to the carbon surface and are reduced before reaching your taps, while the carbon stage also helps lower other organic compounds that travel the same routes.
To work reliably in a Dennet home, an activated carbon PCB filter needs sufficient contact time and enough media for your household flow so adsorption isn't overwhelmed during peak use. A sediment pre-filter is commonly installed upstream to protect the carbon from clogging, but the carbon stage is where PCBs are captured. Proper system sizing and scheduled cartridge or media replacement matter because adsorption capacity diminishes with use — Mr. Pure Water can evaluate your home and recommend a whole-house carbon system matched to your needs.
