Including filter system and high-performance PFOS filter.
PFOS is a member of the PFAS family that can persist in groundwater and municipal supplies because it does not break down easily. Over time small inputs can lead to continual presence in water, so many Fidelis residents discover potential exposure through local testing, water quality reports, or news stories. If you’re worried about PFOS in your home’s water, the sensible first steps are confirming what’s present with testing and selecting treatment specifically designed to address PFAS compounds.
PFOS usually has no taste, smell, or visible signs, so it’s not something you can detect by looking at or sampling water at the tap. That makes it harder for Fidelis homeowners to assess risk by feel alone, and it’s better thought of as a long-term exposure issue rather than an immediate nuisance. Treating water where it enters your house — a whole-house approach — ensures reductions apply to drinking, cooking, bathing, and laundry throughout your home.
For whole-house reduction of PFOS, the most effective single technology is a high-capacity granular activated carbon (GAC) system formulated for PFAS removal. GAC removes PFOS by adsorbing it onto the media’s large internal surface area as water flows through. Because PFOS is tougher for filters than ordinary taste-and-odor contaminants, the quality of the carbon, bed depth and correct flow rate are important considerations. A properly sized whole-house GAC unit can protect every tap in a Fidelis home without needing separate under-sink units.
A whole-house GAC filter is installed on the main water line so all faucets and fixtures in your Fidelis home receive treated water; sizing it to your peak flow and keeping to scheduled media changeouts preserves PFOS reduction. Mr. Pure Water can help select a carbon configuration suited to PFOS control and to your home’s plumbing and usage patterns, and periodic before-and-after testing provides verification that the system continues to perform.
