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 occasionally be found in water supplies. Historically used in electrical equipment and manufacturing, these compounds don’t break down easily and can linger in sediments and waterways. Havana homeowners most often hear about them through utility reports, neighborhood conversations, or private water tests, since their presence isn’t always obvious without sampling.
Because PCBs usually occur at very low concentrations, you won’t be able to detect them by sight, smell, or taste in tap water. They can enter drinking sources from old contamination, disturbed sediments, or runoff that carries pollutants into surface waters. Even if your Havana tap water appears clear, it’s reasonable to worry about long-term exposure for cooking, bathing and laundry. Installing a whole-house system treats water at the point it enters your home, protecting all faucets and appliances rather than a single fixture.
The most effective single-filter option for whole-house removal of PCBs is an activated carbon filter—commonly a catalytic carbon or carbon block media—because these hydrophobic organic compounds adsorb strongly to carbon. Unlike basic sediment filters, high-quality carbon media capture polychlorinated biphenyls as water flows through the bed, reducing the amount that reaches your taps. A properly designed whole-home carbon stage also helps remove other organic contaminants that travel with similar sources, improving overall water quality for Havana households.
To work reliably for Havana homes, an activated carbon PCB system needs sufficient contact time and enough carbon volume sized for your household flow and peak demand. A sediment pre-filter is commonly installed ahead of the carbon to prevent premature clogging, while the carbon stage does the bulk of the PCB removal. Because adsorption capacity is finite, periodic media or cartridge replacement and correct system sizing are essential. Mr. Pure Water can evaluate your home and recommend a whole-house carbon system matched to your needs so PCBs are addressed at the plumbing entry point.
