Including filter system and high-performance Sodium filter.
Sodium in household water is often invisible, so Portland homeowners may not notice it until a change in taste or a lab test reveals it. It can dissolve into groundwater as it passes through mineral-bearing soils and rock, and some treatment or softening processes can raise dissolved sodium levels. If you or your family follow a low-sodium diet, it’s worth checking what’s in your water and understanding how it may contribute to daily intake.
When sodium is present at higher levels, people commonly report a faintly salty or mineral taste — especially obvious in beverages and cooking. Sodium behaves differently than hardness minerals such as calcium and magnesium, so it won’t create the same scale buildup, but it can change the flavor of tap water. Because sodium is dissolved, simple sediment filters or boiling won’t remove it; a water test and tailored treatment plan are the most reliable ways to determine the right next steps for your Portland home.
The single most effective treatment for removing sodium is a reverse osmosis (RO) system. RO uses a fine membrane to reduce dissolved salts and ions, including sodium, which commonly pass through standard whole-house carbon and sediment stages. A correctly sized RO system provides low-sodium water for drinking and cooking — ideal for the kitchen tap where it matters most in Portland households.
Because reverse osmosis separates dissolved minerals from water, it’s usually installed as a dedicated drinking-water system at the kitchen sink or another point of use rather than as a whole-house device. Whole-house carbon filters handle chlorine, odors, and many organics well but are not designed to remove sodium. If your Portland home uses a water softener, note that many softeners can raise sodium in the treated water, making RO a helpful complement. Mr. Pure Water can recommend the right RO configuration and prefiltration so the system runs efficiently and meets your household needs.
