Including filter system and high-performance Vanadium filter.
Vanadium is a metal that occurs naturally in soils and rocks and can make its way into drinking water as those minerals dissolve. In Marathon you won’t usually notice vanadium by sight, smell, or taste, so the only reliable way to know if it’s present is through testing — for example, a well lab report or your utility’s water quality statement. If your results show elevated vanadium, it’s worth considering a treatment plan targeted at reducing metals throughout the house.
Levels of vanadium can change from one neighborhood to another and between wells, since it’s connected to local groundwater chemistry and geology. In Marathon’s coastal setting — where some homes draw from municipal supply and others use private wells or cisterns — vanadium can show up alongside other dissolved minerals even when water looks clear. The aim is reliable, ongoing reduction so your household water for drinking, cooking and bathing is consistent across every faucet.
For whole-house protection, the single filter type most effective at reducing vanadium is a reverse osmosis system configured as a point-of-entry unit. Reverse osmosis forces water through a semipermeable membrane that separates many dissolved contaminants, including metal ions, from the water. That membrane approach treats what you can’t detect by taste or smell and is a sensible choice for Marathon homeowners who have test results indicating vanadium and want coverage at every tap.
A whole-house reverse osmosis system is typically installed with prefiltration to remove sediment and protect the membrane — especially useful in the Keys where coastal air and storms can increase corrosion and particulate load. Many installations also include post-treatment to restore water balance after RO. Because RO performance depends on your water chemistry, pressure and household demand, Mr. Pure Water can evaluate Marathon properties and recommend the right configuration so vanadium reduction is dependable day after day.
