Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals that persist in the environment and may turn up in water supplies. Also called polychlorinated biphenyls, these compounds were once common in electrical gear and manufacturing. Because they break down slowly, PCBs can remain in sediments and waterways for long periods. In Key West, homeowners often hear about potential contaminants through utility notices, local conversations in neighborhoods like Old Town or Casa Marina, or by getting an independent water test.
At the very low concentrations PCBs usually occur, you won’t detect them by sight, smell, or taste in tap water. They can enter drinking water via past contamination, disturbed sediments, or runoff that carries pollutants into nearby waters. Even in clear water in Key West — whether you live near Duval Street or the quieter parts of New Town — concerns about long-term exposure for cooking, bathing, and laundry are reasonable. A whole-house filtration strategy treats every faucet and appliance, so addressing PCBs covers routine household use, not just a single tap.
The best single-filter option for removing PCBs in a whole-house system is a high-quality activated carbon filter, typically using catalytic carbon or a carbon block designed for strong adsorption. Because PCBs are hydrophobic organic compounds, they’re well suited to being captured by carbon media rather than by sediment-only filters. As water flows through the carbon, polychlorinated biphenyls adhere to the media and are reduced before reaching your plumbing. A whole-house carbon system also helps with other organic contaminants that travel by similar routes into your Key West home.
To work reliably in Key West’s homes, an activated carbon PCB filter must provide sufficient contact time and enough media volume for your household flow, especially during peak use. It’s common to pair a sediment pre-filter upstream to protect the carbon from clogging, while the carbon stage does the heavy lifting for PCBs. Regular cartridge or media replacement is essential because adsorption capacity is finite. Mr. Pure Water can size and install a whole-house carbon system matched to your property in Monroe County so incoming water is treated before it reaches fixtures and appliances.
