Including filter system and high-performance PFOS filter.
PFOS is a member of the PFAS family that can persist in water and the environment for many years. Because it breaks down slowly, small releases over time may lead to continued presence in a supply. Lewis residents typically hear about PFOS through local reports, news, or private testing; if you’re worried, the sensible first step is to confirm what’s in your water and pursue treatment designed specifically for PFAS contaminants.
PFOS doesn’t change the look or smell of water the way chlorine does, so you can’t rely on taste or appearance to assess it at your Lewis tap. It’s generally considered a long-term exposure concern rather than an obvious nuisance. Treating at the point where water enters your house ensures reductions affect drinking, cooking, bathing and laundry throughout your home.
For whole-house removal, the single most effective 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 common taste-and-odor compounds, media quality, bed depth and correct flow rates are important. A properly sized whole-house GAC unit can protect an entire Lewis home without needing multiple under-sink filters.
A whole-house GAC filter is mounted on the main water line so every fixture in your Lewis home receives treated water; it must be sized for peak household flow and serviced with timely media changeouts. Mr. Pure Water can recommend a GAC configuration matched to PFOS reduction needs and your home’s plumbing and usage patterns. For added assurance, consider periodic testing of water before and after the system to confirm continued performance.
