Including filter system and high-performance Sodium filter.
Sodium in your household water is usually invisible, so many Sewall's Point homeowners only notice it when the taste changes or a lab test flags it. It can leach from mineral-rich soils and rock as groundwater moves, and certain treatment steps or softening methods can also raise sodium levels. If you’re keeping a close eye on dietary sodium, it’s worth checking what’s in your water so you know whether it belongs in your daily count.
Some people in Martin County say higher-sodium water tastes slightly salty or mineral-like in coffee, tea, soups, or baby formula. Sodium behaves differently than the hard water minerals common along the Treasure Coast, like calcium and magnesium, so it won’t produce the same scale buildup even though our coastal water is often hard. Because sodium is dissolved, it won’t be trapped by simple sediment filters and boiling won’t remove it—only a water analysis and a tailored treatment plan will make the situation clear.
To reduce sodium specifically, the single most effective option is reverse osmosis. RO relies on a fine membrane that removes dissolved salts and ions such as sodium rather than just capturing particles, which is important when a contaminant is fully dissolved. Standard whole-house carbon or sediment stages won’t reliably lower sodium, so a properly sized RO system gives low-sodium water for drinking and cooking where it matters most in your Sewall's Point home.
Because reverse osmosis separates dissolved minerals from water, it’s most often installed as a dedicated system for a kitchen tap or another point of use where sodium reduction is needed. Whole-house carbon filters are great for chlorine, odors, and many organics but aren’t designed to remove sodium. If you use a water softener—a common pairing where coastal Martin County water is hard—be aware some softeners can raise sodium levels in treated water, making RO a useful complement. Mr. Pure Water can help Sewall's Point homeowners pick the right RO size and prefiltration so the system performs efficiently for your household.
