Including filter system and high-performance GenX filter.
GenX is a type of PFAS sometimes found in drinking water when industrial compounds reach waterways or aquifers. Also called HFPO-DA, it’s grouped with other persistent “forever chemicals” because it can linger in the environment. Homeowners in San Castle usually can’t detect GenX by sight or taste, so testing is the reliable way to learn what’s in your tap water. When homeowners want to lower exposure across the household, many look to treatment options that protect every tap.
Because GenX generally appears at very low concentrations, treatment aimed at PFAS is needed rather than a basic odor or taste filter. A point-of-use unit at the kitchen sink helps with drinking and cooking but won’t protect showers, laundry, or other daily uses common in San Castle households. A whole-house system treats incoming water for the entire home, providing consistent reduction at every faucet and showerhead. The best results come from a system sized and maintained for your household’s demand and local water conditions.
For whole-home removal, granular activated carbon (GAC) is the single filter media most effective for GenX and related PFAS — when the system is properly designed with high-quality carbon and adequate contact time. GenX (HFPO-DA) can be tougher to capture than some long-chain PFAS, so factors like carbon type, bed depth, and flow rate matter. A GAC tank installed at the main line treats all water entering a San Castle home, reducing GenX at showers and faucets without introducing chemicals into your water.
Activated carbon removes contaminants by adsorption, so performance depends on giving water enough contact time and replacing media before it’s spent. Heavy household use, fast flow rates, or other competing contaminants can shorten carbon life, which is why proper sizing and a maintenance plan are important for San Castle homes. Mr. Pure Water sizes whole-house GAC systems to match a home’s plumbing needs, and periodic testing can confirm how well the system is reducing GenX and when service is recommended.
