Including filter system and high-performance PFOS filter.
PFOS is one of the PFAS chemicals that can persist in the environment for many years. Because it breaks down slowly, small inputs can remain in a water source over time. Marathon homeowners typically hear about PFOS from local water quality reports, news, or private testing, and the sensible first step is confirming what’s in your supply. From there, choose a treatment that specifically targets PFAS compounds so you can address the issue at the source.
PFOS doesn’t change the taste, smell, or appearance of water the way chlorine or organic issues might, so you can’t rely on your senses to know it’s present. That’s why many residents of Marathon — whether on municipal lines or private wells and cisterns — prefer treatment where the water first enters the home. A whole-house approach protects drinking, cooking, bathing and laundry, and is especially useful in coastal properties where corrosion and sediment control are also concerns.
For whole-home PFOS control, the most effective single solution is a high-capacity granular activated carbon (GAC) filter formulated for PFAS removal. GAC removes PFOS by adsorbing it onto a large internal surface area as water flows through, and because PFOS is tougher to remove than common taste-and-odor contaminants, media quality, bed depth and correct flow rates are important. A properly sized whole-house GAC unit treats every fixture in the home without needing multiple under-sink devices.
Whole-house GAC filters mount on the main water line so every tap in your Marathon home gets treated water; sized to handle peak household flow, they require scheduled media changeouts to remain effective. Mr. Pure Water can help select a carbon configuration suited for PFOS while accounting for local factors like moderate water hardness, coastal corrosion concerns, and whether you’re on municipal supply or a private well/cistern. Periodic before-and-after testing provides extra assurance that the system is performing as expected.
