Including filter system and high-performance Sodium Chloride (Salt) filter.
Sodium chloride, often called salt, can appear in household water for several reasons: it may be naturally present in source water, show up in groundwater, or be introduced during treatment and regeneration processes. A modest amount of dissolved minerals is typical, but higher salt levels make water taste brackish and leave homeowners wondering about what they’re drinking and cooking with. If you’re in Chapel Hill and watching your sodium intake, it’s especially annoying because you can’t detect salt by sight alone.
Elevated salt in water can also change how it performs around the house — you might taste it in coffee, notice it in ice, or see a faint film on fixtures and glass that won’t easily wipe away. Because sodium chloride dissolves completely, sediment filters won’t trap it and boiling won’t remove it either. The smart first move for Chapel Hill homeowners is a water test to determine whether the source is the incoming supply, a softener regeneration issue, or something else.
When the goal is removing dissolved sodium chloride, the single most effective filter is a reverse osmosis system. RO relies on a semi-permeable membrane to separate dissolved salts from water — a function that carbon or sediment filters can’t provide, since they mainly remove particles, chlorine, and taste-and-odor compounds. This is the core technology used for desalination and reducing total dissolved solids, so when salt is your main concern, picking the right membrane and system configuration is more important than adding extra carbon stages.
For whole-house protection, reverse osmosis is usually set up as a dedicated system with prefiltration to shield the membrane and keep it working reliably. Prefiltering sediment reduces fouling, and carbon prefiltration helps remove chlorine that could shorten membrane life if it’s present. Because RO creates both a purified stream and a reject stream, correct sizing and professional installation matter for everyday household demand. Mr. Pure Water serves Chapel Hill homeowners — we can test your water, trace the source of salt, and design a whole-house RO solution tailored to your home’s needs.
