Including filter system and high-performance GenX filter.
GenX is a type of PFAS that can enter drinking water when industrial chemicals reach local waterways or sources, and it’s also called HFPO-DA. Like other “forever chemicals,” it can persist in the environment and is generally invisible and tasteless in your tap water, which makes testing the only reliable way to know if it’s present. Lewis homeowners who want to lower their household exposure often look for practical treatment solutions that protect every tap, not just a single faucet.
Because GenX typically appears at very low concentrations, effective treatment needs PFAS-focused technology rather than basic taste-and-odor filters. A point-of-use filter at the kitchen sink helps for drinking and cooking, but it won’t protect showers, laundry, toothbrushing, or ice makers in a Lewis home. Installing whole-house filtration treats water as it enters your house so everyday uses are covered; the aim is steady reduction with a system sized and serviced to match your household’s water use patterns.
For whole-house treatment, the most effective single media for GenX and other PFAS is a properly designed granular activated carbon (GAC) system that uses high-quality carbon and allows sufficient contact time. GenX (HFPO-DA) can be harder to remove than some long-chain PFAS, so the specifics matter: carbon type, bed depth, flow rate, and how quickly the media is exhausted. A GAC tank installed at the main line treats all incoming water in a Lewis residence, helping reduce GenX at showers and faucets without adding chemicals to the supply.
Activated carbon removes contaminants by adsorption, so performance depends on contact time and timely media replacement. Higher flow rates, heavy water use, and competing contaminants shorten carbon life, which is why proper sizing and a maintenance plan matter for Lewis homes. Mr. Pure Water designs whole-house GAC systems around a household’s plumbing needs to keep GenX reduction consistent, and periodic water testing can confirm results and indicate when service is needed.
