Including filter system and high-performance PFOA filter.
PFOA is a manufactured PFAS compound that can enter drinking water from industrial sources and long-lasting products in the environment. Because it degrades very slowly, it can remain in water supplies long after releases stop, and you usually can’t see, smell, or taste it—testing is how most homeowners discover it. If you’re in Lois and worried about PFOA, the first step in protecting your household is learning how the chemical behaves in water and what treatment options make sense for your home.
Even crystal-clear water from the tap can carry dissolved contaminants like PFOA that ordinary filters don’t remove. Simple sediment cartridges help with grit, and water softeners address minerals, but neither is designed to capture PFAS chemicals. Many Lois families choose a whole-house solution so treated water is delivered to every faucet and shower—giving consistent protection for cooking, bathing, and laundry rather than just at a single point of use.
For whole-home reduction of PFOA, a granular activated carbon (GAC) filter is often the most effective single-filter choice. Carbon media can adsorb PFAS compounds like PFOA when water passes through a correctly sized tank that provides sufficient contact time. The system works best when the carbon grade and tank design match your household flow, so performance isn’t reduced when multiple fixtures run simultaneously. In Lois, installing the right GAC whole-house unit can lower PFOA exposure across every tap.
Because PFOA is dissolved rather than particulate, a small “taste and odor” cartridge won’t deliver meaningful reduction for an entire home. A professionally sized whole-house GAC tank offers greater capacity and longer contact time than point-of-use filters, which can be overwhelmed by whole-home demand. Regular maintenance is essential since carbon’s adsorption capacity is limited and must be replenished on schedule. Mr. Pure Water works with Lois homeowners to select and maintain the right whole-house carbon filtration system so PFOA reduction stays reliable over time.
