Including filter system and high-performance PFOS filter.
PFOS is one of the PFAS chemicals that can persist in water and the environment for a very long time. Because it doesn’t break down easily, occasional introductions can lead to lasting presence in a system. Old Town homeowners often first hear about PFOS from water quality reports, local news, or results from a private test. If you’re worried, the best next steps are confirming what’s in your well or supply and choosing treatment designed specifically for PFAS removal.
PFOS won’t usually affect taste or smell the way chlorine does, so you can’t rely on your senses to know if it’s present in Old Town water. Because the concern is long-term exposure rather than immediate nuisance, many residents prefer to treat incoming water for the whole house so drinking, cooking, bathing, and laundry are all covered. A whole-home approach gives practical, consistent protection across everyday uses.
For whole-house reduction of PFOS, the most effective single filter type is a high-capacity granular activated carbon (GAC) system formulated for PFAS. GAC removes PFOS by adsorbing it onto extensive internal surfaces as water flows through the media. Since PFOS is tougher to remove than routine taste-and-odor issues, media quality, adequate bed depth, and correct flow rates are important. A properly sized whole-house GAC unit can protect your entire Old Town home without requiring multiple under-sink devices.
A whole-house GAC filter mounts on the main water line so every faucet and appliance in your Old Town home receives treated water; it should be sized for peak household flow and serviced with regular media changeouts. Mr. Pure Water can help pick a carbon configuration suited for PFOS reduction and your plumbing layout. For added peace of mind, we recommend periodic testing before and after installation to confirm the system’s performance over time.
