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 and sources. Also called HFPO-DA, it’s grouped with other “forever chemicals” because it persists in the environment. You usually can’t see, smell, or taste GenX, so testing is the only reliable way to know if it’s present in your water. Many Cox homeowners choose practical treatment options to reduce exposure at every tap when they learn levels may be elevated.
Because GenX generally appears at very low concentrations, it needs PFAS-specific treatment instead of basic taste-and-odor solutions. A point-of-use filter at a kitchen sink helps for drinking and cooking but won’t protect showers, laundry, or other household uses. Installing a whole-house system treats water as it enters your Cox residence so every faucet and shower benefits. The aim is steady reduction with equipment sized and maintained for your household’s daily demand.
For whole-house removal, the single most effective filter media for GenX and similar PFAS is a properly designed granular activated carbon (GAC) system using high-quality carbon and enough contact time. GenX (HFPO-DA) can be harder to capture than some longer-chain PFAS, so factors like carbon type, bed depth, and flow rate matter. A GAC tank on the main line treats all incoming water to reduce GenX at showers and faucets throughout your Cox home without adding chemicals.
Activated carbon removes contaminants by adsorption, so performance depends on adequate contact time and timely media replacement. High household water use, faster flow rates, and other competing contaminants can reduce carbon life, which is why correct sizing and maintenance are important. Mr. Pure Water tailors whole-house GAC systems to a home’s plumbing needs in Cox so GenX reduction is consistent, and periodic testing can confirm results and indicate when service is needed.
