Including filter system and high-performance Tungsten filter.
Tungsten is a naturally occurring metal that can end up in drinking water at low concentrations. It can leach from certain rock and soil types or be influenced by nearby industrial activities, and because tungsten is usually colorless and odorless you won’t detect it without lab testing. Many Key West homeowners—whether in Old Town, Truman Annex, or New Town—choose to identify metals of concern like tungsten so they understand what’s in their taps and can make an informed plan for treating their water.
While science around tungsten in drinking water is still developing, a practical, cautious approach makes sense if testing shows elevated levels. Even crystal-clear water can contain dissolved metals, and seasonal shifts or storm events during hurricane season can change water quality in the Keys. If your home relies on a private well, routine testing keeps you aware of changes; if you’re on municipal supply, review the latest water quality reports and test at the tap to confirm what’s entering your plumbing in Monroe County.
To reduce tungsten at the point of entry, a whole-house reverse osmosis system is generally the most effective single-filter option. RO relies on a semipermeable membrane that rejects many dissolved metals and inorganic contaminants, helping lower tungsten before water reaches faucets, showers, and appliances in your Key West home. Because tungsten often exists as dissolved species, it can pass through simpler media used for taste and odor, so a properly designed whole-house RO with prefiltration is important to protect the membrane from sediment and chlorine where present.
A whole-house reverse osmosis installation can include dedicated storage and delivery so you have consistent treated water throughout the house. Long-term performance depends on correct sizing, sufficient pressure, and routine maintenance of filters and the membrane to avoid fouling—salt air and coastal conditions in Key West can accelerate corrosion and may affect component life. Homes on wells may need additional pretreatment for hardness, iron, or particulates that can shorten membrane life; Mr. Pure Water can review your water test results and recommend a whole-house RO system tailored to your Key West property.
