Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals that persist in the environment and can occasionally turn up in drinking water. Also called polychlorinated biphenyls, they were commonly used in older electrical gear and some manufacturing processes. Once they get into waterways they can stick around because they don’t break down easily, so homeowners in McDavid sometimes hear about them through utility notices, neighborhood conversations, or independent testing of well or tap water.
Because PCBs typically exist at very low concentrations, you won’t be able to detect them by sight, smell, or taste in tap water. They can enter local water sources from past contamination, disturbed sediments, or runoff that carries legacy pollutants into surface waters. Even if your McDavid tap water looks and smells normal, it’s reasonable to want protection for long-term household use—cooking, bathing, laundry and other daily activities—which is why many homeowners prefer a whole-house strategy rather than treating a single faucet.
The best single-filter option for whole-house PCB reduction is a quality activated carbon system, typically using catalytic carbon or a carbon block designed for strong adsorption. Because PCBs are hydrophobic organic compounds, they’re captured more effectively by carbon media than by simple sediment filters. As water flows through the carbon bed, polychlorinated biphenyls can adhere to the carbon surface and be reduced before water reaches your taps, while also lowering many other organic contaminants that travel with similar sources.
An activated carbon PCB filter works well only if it has enough contact time and media volume to handle your home’s flow, so proper sizing for McDavid homes is important. Many installations pair a sediment pre-filter upstream to protect the carbon from premature clogging, but the carbon stage does the primary removal. Because adsorption capacity is finite, routine media or cartridge changes are necessary. Mr. Pure Water can evaluate your home’s needs and recommend a whole-house carbon system sized to treat water where it enters your plumbing.
