Including filter system and high-performance GenX filter.
GenX is a member of the PFAS family that can enter drinking water when industrial chemicals reach waterways or groundwater. Often called HFPO-DA, it’s grouped with other “forever chemicals” because it can persist in the environment. Homeowners in Allentown usually can’t see, smell, or taste GenX, so testing is the only reliable way to know if it’s present; when levels are a concern, many families want a practical solution that reduces exposure at every tap.
Because GenX commonly appears at very low concentrations, it requires PFAS-specific treatment rather than ordinary taste-and-odor filters. You can protect drinking and cooking water with a point-of-use filter at one sink, but that won’t cover showers, laundry, or other household uses in an Allentown home. A whole-house filtration system treats water as it enters your house so every faucet and fixture benefits. The objective is steady reduction across daily uses, with a system sized and serviced for your household’s water demand.
For whole-house protection, the single filter media proven most effective against GenX and related PFAS is a properly designed granular activated carbon (GAC) system built with high-quality carbon and adequate contact time. Because GenX (HFPO-DA) can be harder to capture than some longer-chain PFAS, factors like carbon type, bed depth, flow rate, and media exhaustion rate are important. A GAC tank installed at the main line in an Allentown residence treats all incoming water so showers and faucets throughout the home receive reduced GenX levels without adding chemicals.
Activated carbon removes contaminants by adsorption, so performance depends on sufficient contact time in the carbon bed and timely media replacement. Heavy household use, high flow rates, and other competing contaminants can shorten the life of the carbon, making proper sizing and maintenance planning essential. Mr. Pure Water sizes whole-house GAC systems around each Allentown home’s plumbing and usage to keep GenX reduction consistent; routine testing can confirm results and indicate when service or media change is needed.
