Including filter system and high-performance PCBs filter.
PCBs are an industrial family of chemicals that persist in the environment and can sometimes end up in drinking water. Also called polychlorinated biphenyls, these compounds were commonly used in older electrical gear and certain industrial processes. Once they enter waterways, PCBs can be slow to break down and may remain in the environment for a long time. Hulaw homeowners often hear about them through utility notices, neighborhood conversations, or independent testing of household water supplies.
Because PCBs typically occur at very low concentrations, you won’t detect them by sight, smell, or taste in tap water. They can reach water sources from legacy contamination, disturbed sediments, or runoff that carries pollutants into surface waters. Even when your water looks clear in Hulaw, concerns about long-term exposure and everyday household uses—cooking, bathing and laundry—can still be valid. Treating water at the point it enters your home ensures protection for every faucet and appliance, not just a single tap.
The most effective single-filter whole-house solution for PCBs is a high-quality activated carbon system, typically using catalytic carbon or carbon block media engineered for strong adsorption. PCBs are hydrophobic organic compounds, so they’re well matched to carbon media rather than basic sediment filters. As Hulaw water flows through the carbon bed, polychlorinated biphenyls attach to the carbon surface and are reduced before reaching your plumbing. A whole-house carbon filter also helps lower other organic contaminants that behave similarly.
To work reliably in a Hulaw home, an activated carbon PCB system needs sufficient contact time and enough media volume for your household’s peak flow. A sediment pre-filter is commonly installed ahead of the carbon to prevent early clogging, while the carbon stage does the bulk of PCB reduction. Correct sizing and regular media or cartridge replacement are essential because adsorption capacity will eventually be spent. Mr. Pure Water can size and install a whole-house carbon system tailored to your home so PCBs are addressed where water enters your plumbing.
