Including filter system and high-performance PFOS filter.
PFOS is one of the PFAS chemicals that can persist in drinking water and resist natural breakdown, so even small inputs can remain in a supply for a long time. Highland homeowners commonly hear about PFOS from utility reports, local news, or private water testing; if it’s on your mind, the recommended first steps are confirming what’s in your water and selecting treatment that specifically targets PFAS compounds.
Because PFOS usually has no taste or odor, you can’t rely on how your tap water looks or smells to know whether it’s present. That’s why many Highland residents treat water where it enters the house—so drinking, cooking, bathing, and laundry are all covered. Treating at the main line addresses long-term exposure concerns rather than temporary nuisance issues like chlorine.
For whole-house reduction of PFOS, the most effective single option is a high-capacity granular activated carbon (GAC) system formulated for PFAS. GAC removes PFOS by adsorbing it onto a very large internal surface area as water flows through the media. Because PFOS can be tougher to remove than simple taste-and-odor compounds, media quality, bed depth and proper flow rate are important; a properly sized whole-house GAC unit can protect an entire Highland home without needing multiple under-sink units.
A whole-house GAC filter mounts on the main service line so every fixture in your Highland house receives treated water; to maintain consistent PFOS reduction it should be sized for your peak flow and maintained with timely media replacements. Mr. Pure Water can recommend a GAC configuration that fits your plumbing and household use, and periodic testing before and after installation gives added assurance that the system is performing as expected.
