Including filter system and high-performance PFOA filter.
PFOA is a synthetic PFAS chemical that can enter drinking water through past industrial uses and lingering products in the environment. Because it degrades very slowly, it can remain in water supplies long after the original source is gone. You usually won’t detect PFOA by smell, taste, or sight, so testing is the only way to know if it’s present. For Delta homeowners worried about PFOA, the first step in effective treatment is understanding how this contaminant behaves in water.
Clear, good-tasting water can still contain dissolved contaminants like PFOA that typical filters don’t remove. Basic sediment cartridges trap particles, and water softeners address minerals, but neither targets PFAS chemicals. Many Delta families prefer a whole-house solution so cooking, bathing, and laundry all receive the same treated water rather than relying solely on a single tap filter.
For whole-home reduction of PFOA, a granular activated carbon (GAC) filter is widely regarded as the best single-filter choice. Properly sized GAC media adsorbs PFAS compounds such as PFOA as water passes through a tank with sufficient contact time. Getting the right carbon grade and system design is important so flow rate and simultaneous fixture use don’t reduce performance. When chosen and installed correctly for a Delta residence, a GAC whole-house filter can lower PFOA exposure across every tap.
Because PFOA is dissolved rather than particulate, a small taste-and-odor cartridge won’t provide reliable removal for the whole house. A professionally sized GAC tank offers greater capacity and longer contact time than point-of-use units, which can be overwhelmed by full-home flow. Carbon’s adsorption capacity is limited, so scheduled maintenance and media replacement are essential to maintain effectiveness. Mr. Pure Water works with Delta homeowners to select and service the right whole-house carbon system so PFOA reduction stays consistent.
