Including filter system and high-performance Sodium filter.
Sodium in household water is usually invisible, so many Marathon Shores homeowners only notice it when a sip tastes slightly off or a lab test flags it. On the Florida Keys’ aqueduct system and in coastal plumbing exposed to sea air, dissolved sodium can come from natural mineral contact or from certain treatment and softening practices. If you’re managing dietary sodium for health reasons, understanding what’s in your tap water is a useful part of your overall plan.
When sodium is higher, people sometimes report a faintly salty or mineral taste — most noticeable in coffee, tea, soups, or baby formula. Sodium behaves differently than hard water minerals like calcium and magnesium and won’t create scale the same way, yet it still changes flavor because it’s fully dissolved. Basic sediment filters or boiling won’t remove it, so the best first step in Marathon Shores is a proper water analysis and a treatment recommendation that fits our coastal, hard-water conditions.
For reducing sodium specifically, reverse osmosis is the single most effective treatment. RO systems force water through a fine membrane that reduces dissolved salts and ions such as sodium, unlike standard whole-house carbon or sediment stages. In homes across Marathon Shores and nearby keys communities, a correctly sized RO setup provides low-sodium water where it matters most — for drinking and cooking at the kitchen tap.
Because reverse osmosis separates dissolved minerals from water, it’s commonly installed as a dedicated unit for the kitchen or other points of use where sodium reduction is critical. Whole-house carbon filters still do great work on chlorine, odors, and many organics but won’t lower sodium. Also note that some water softeners can raise sodium levels in treated water, so pairing RO with the right prefiltration is often the best approach for Marathon Shores homes—especially here in the Florida Keys where corrosion and salt air can affect plumbing. Mr. Pure Water can help size an RO system and select prefilters so it runs efficiently and fits your household needs.
