Including filter system and high-performance Sodium Chloride (Salt) filter.
Sodium chloride, often just called salt, can end up in household water for several reasons: it may occur naturally in source water, be present in groundwater, or be introduced through certain treatment or regeneration processes. A modest amount of minerals is normal, but higher salt levels can make tap water taste brackish and leave you wondering about what you’re using for drinking and cooking. For Littman homeowners who monitor sodium intake, the invisible nature of dissolved salt can be especially concerning since it won’t show up visually in a glass.
Elevated salt changes how water performs around the house — from a persistent taste in beverages and ice to a filmy residue on fixtures and glass that won’t easily wipe away. Because sodium chloride dissolves fully, it passes through common sediment filters and isn’t removed by boiling. The right first move for a Littman residence is to test your water so you can determine if the source is the municipal supply, well water, a water softener regeneration issue, or another contributor.
When the goal is removing dissolved sodium chloride, a reverse osmosis system is the most effective single-filter solution. RO relies on a semi-permeable membrane to separate dissolved salts from water, unlike carbon or sediment filters that mainly target particles, chlorine, and odors. This is the same core technology used for desalination and reducing total dissolved solids, so if salt is your primary worry in a Littman home, choosing the right RO membrane and system configuration matters more than adding extra carbon stages.
For whole-house applications, reverse osmosis is typically built as a dedicated treatment system with prefiltration to protect the membrane and maintain consistent performance. Prefiltration with sediment filters prevents fouling, and carbon prefilters reduce chlorine that can shorten membrane life when present. Because RO creates both a purified stream and a reject stream, proper sizing and professional installation are important to meet everyday household demands. Mr. Pure Water in Littman can test your water, identify the source of salt, and design a whole-house RO solution tailored to your family’s water use.
