Including filter system and high-performance PCBs filter.
PCBs are a group of industrial chemicals that resist breaking down and can linger in the environment, sometimes making their way into water sources. Also called polychlorinated biphenyls, these compounds were commonly used in older electrical equipment and in some manufacturing, and they can be transported into waterways through runoff or disturbed sediments. In Esto, homeowners often hear about them from utility notices, community conversations, or private water testing, since they’re not something you can detect by sight or smell.
Because PCBs typically occur at trace levels, you won’t notice them by tasting or smelling your tap water. They can reach drinking supplies via past contamination, runoff, or sediment disruption, meaning clear water from the tap doesn’t guarantee absence of concern. For Esto families, a whole-house plan treats all the water you use—cooking, showering, laundry—so protection isn’t limited to a single faucet or pitcher.
The most effective single-filter option for a whole-house system to address PCBs is high-quality activated carbon—typically catalytic carbon or a dense carbon block engineered for strong adsorption. PCBs are hydrophobic organic molecules, which makes them a good match for carbon media rather than simple sediment screens. As your home’s water flows through the carbon, polychlorinated biphenyls bind to the media surface, lowering levels before water reaches bathrooms and the kitchen. A whole-house carbon stage also helps reduce many other organic contaminants that travel with similar sources.
To work reliably for an Esto home, an activated carbon PCB filter must be sized with enough media and contact time for your household flow—especially during peak use—so it treats water consistently. Sediment pre-filtration is commonly installed ahead of the carbon to prevent premature clogging, while the carbon stage does the primary removal. Regular media or cartridge replacement is essential because adsorption capacity is finite.
