Including filter system and high-performance GenX filter.
GenX is one of the PFAS family of chemicals that can enter drinking water when industrial compounds reach local water sources. Often called HFPO-DA, it’s discussed with other “forever chemicals” because it can persist in the environment. Homeowners in Barth won’t see or taste GenX, so testing is the only way to know whether it’s present — and when levels cause concern many families look for practical solutions that reduce exposure at every tap.
Because GenX typically occurs at very low concentrations, treatment aimed at PFAS is needed rather than simple taste-and-odor fixes. A point-of-use filter at a single sink helps for drinking and cooking, but won’t protect showers, laundry, tooth brushing, or ice makers in Barth homes. Whole-house filtration treats water as it enters your house so everyday uses are covered, delivering consistent reduction when the system is sized and maintained for your household’s demand.
For whole-house systems, the single filter media most effective for GenX and related PFAS is a well-designed granular activated carbon (GAC) system that uses high-quality carbon and provides adequate contact time. GenX (HFPO-DA) can be harder to capture than some longer-chain PFAS, so carbon type, bed depth, flow rate, and media exhaustion all matter. A GAC tank installed at the main water line treats all incoming water to help reduce GenX at Barth showers and faucets without adding chemicals.
Activated carbon removes contaminants by adsorption, so effectiveness depends on allowing sufficient contact time and replacing media on schedule. Heavy water use, fast flow rates, or other competing contaminants shorten carbon life, which is why proper sizing and a maintenance plan matter for Barth households. Mr. Pure Water designs whole-house GAC systems around a home’s plumbing needs, and periodic testing can confirm results and indicate when service or media replacement is needed.
