Including filter system and high-performance PFTA filter.
PFTA is a synthetic chemical that can persist in the environment and turn up in drinking water supplies. In Marathon you might hear about it from a utility report, local news, or a private lab test of a well or municipal connection. Because PFTA doesn’t necessarily affect taste, smell, or clarity, the only reliable way to detect it is through testing — and if results are elevated, homeowners often seek a whole-home solution to reduce exposure throughout the property.
Contamination with PFTA reaches every faucet once it’s in the plumbing, so it can affect drinking water, cooking, bathing and laundry across your Marathon home. That’s why many Keys residents choose a whole-house filter — it treats water at the main service line so clean water flows to showers, dishwashers and outdoor taps. A correctly specified system can also help with other common water concerns here, like moderate hardness and sediment from well or cistern supplies influenced by coastal conditions.
The most effective single-filter option for whole-house PFTA reduction is a high-quality activated carbon system, usually built with catalytic or dense carbon media that provides extended contact time. Carbon removes trace organic contaminants by adsorption as water moves through the media, so factors like media type, flow rate and tank capacity are key — especially in Marathon homes where storm-driven corrosion and salt air can affect plumbing. A whole-house carbon tank is fitted on the main line so every fixture receives treated water, avoiding the limits of pitchers or under-sink cartridges.
Maintaining PFTA reduction depends on adequate contact time, so Mr. Pure Water sizes whole-house carbon tanks for real household flow rates — not just low-flow testing conditions — so showers, appliances and taps in Marathon perform reliably. Activated carbon media must be replaced on a regular schedule before adsorption capacity is spent, and we recommend periodic water testing to verify the system continues reducing PFTA as expected given local factors like moderate hardness and coastal exposure.
