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 readily, small amounts can remain in a supply over time. Homeowners in Thompson typically hear about PFOS from water quality reports, local news, or results from a private test; if you’re worried, start by confirming what’s in your water and then choose treatment designed specifically for PFAS.
PFOS usually can’t be seen or smelled like chlorine or sediment, so it’s hard to judge by appearance alone whether it’s present. That’s why it’s treated as a long-term exposure issue rather than an immediate nuisance. A sensible option for Thompson homes is to install treatment where water enters the house so drinking, cooking, bathing, and laundry all receive the same level of protection.
The most effective single filter for whole-house PFOS reduction is a high-capacity granular activated carbon (GAC) system formulated for PFAS removal. GAC removes PFOS by adsorbing it onto media with a very large internal surface area as water passes through. Because PFOS can be harder to remove than ordinary taste-and-odor compounds, media quality, bed depth and correct flow rates are important—especially in humid subtropical climates like Thompson’s where seasonal rain patterns and mineral-rich groundwater can affect loading. A properly sized whole-house GAC system treats the entire home without needing multiple under‑sink units.
A whole-house GAC unit sits on the main water line so every faucet and appliance in your Thompson home gets treated water; it must be sized for peak household flow and maintained with scheduled media replacement. Mr. Pure Water can help select a carbon configuration matched to PFOS concerns and to your plumbing and usage patterns, and we recommend occasional testing before and after installation to confirm continued performance.
