Including filter system and high-performance Tungsten filter.
Tungsten is a naturally occurring metal that can enter drinking water in trace amounts. In coastal communities like Marathon Shores, changes in groundwater chemistry, interactions with local soils and rock, or human activities can influence which metals appear in your plumbing. Because tungsten is typically colorless and odorless, routine lab testing is the only reliable way to detect it. Many Marathon Shores homeowners begin by screening for metals of concern, including tungsten, to get a clear picture of what’s in their water.
While research on tungsten in drinking water is ongoing, homeowners often take a practical, conservative approach when tests show elevated levels. Water that looks and tastes normal can still contain dissolved metals, so periodic testing is wise—especially for private supplies or after storm events that can affect plumbing in the Florida Keys. If you receive water via the regional supply, check local consumer confidence reports and consider tap testing to confirm what actually reaches your faucets in Marathon Shores.
To reduce tungsten at the point of entry, a whole-house reverse osmosis system is generally the most effective single-filter option. RO uses a semipermeable membrane to reject many dissolved metals and inorganic contaminants, lowering tungsten before water gets to showers, appliances, and drinking taps. Simpler media that target taste and odor won’t reliably remove dissolved tungsten, so a properly designed whole-house RO system—complete with prefiltration to protect the membrane from sediment and chlorine where present—is the recommended choice for Marathon Shores homes.
A whole-house reverse osmosis setup can include storage and delivery components to supply treated water throughout your home, but performance depends on correct sizing, sufficient pressure, and routine maintenance to prevent membrane fouling. In Marathon Shores and the broader Monroe County area, hard water and coastal conditions can increase the need for pretreatment to address hardness, particulates, or corrosion that shorten membrane life. Mr. Pure Water can evaluate your water test results and design a whole-house RO system tailored to Marathon Shores homes to reliably target tungsten.
