Including filter system and high-performance Sodium Chloride (Salt) filter.
Sodium chloride, often just called salt, can make its way into household water for several reasons — from natural groundwater conditions to water treatment and regeneration processes. In Rio’s humid subtropical climate, that subtle brackish flavor can be especially noticeable when you’re drinking, cooking, or making ice. If you’re monitoring sodium for health reasons, it’s frustrating because salt is invisible in a glass and can leave you unsure about the water coming from your tap.
Elevated salt changes how water behaves around the home: you may detect a lingering taste in coffee, tea, or ice, or see a dull film on fixtures that coastal salt-air and corrosion already make worse in Rio. Because sodium chloride dissolves completely it bypasses sediment filters and won’t be removed by boiling. The smartest first move is to test your water so you can tell whether the source is the incoming supply, a nearby softener or regeneration process, or something else.
To remove dissolved sodium chloride effectively, the best single-filter choice is a reverse osmosis system. RO uses a semi-permeable membrane to separate dissolved salts from water, unlike carbon or sediment filters that focus on particles, chlorine, and odors. This membrane-based approach is the same core technology used in desalination and for lowering total dissolved solids, so when salt is your main concern the right RO membrane and setup matter most.
For whole-house protection, reverse osmosis is typically set up as a dedicated system with prefiltration to shield the membrane and keep performance steady. Sediment prefilters prevent fouling and carbon prefilters reduce chlorine that can shorten membrane life when present. Because RO creates both a purified stream and a rinse stream, careful sizing and professional installation are important for everyday Rio household demand — especially when storm-related outages can affect pumps and treatment systems. Mr. Pure Water can test your water, identify the salt source, and design a whole-house RO system tailored to your home.
