Including filter system and high-performance Tungsten filter.
Tungsten is a metal that occurs naturally and can enter drinking water at low concentrations. In some places elevated levels happen when groundwater interacts with certain rock or soil types or when nearby industrial activity affects local sources. Because tungsten is usually colorless and odorless in water, it won’t be obvious without laboratory testing. Portland homeowners who want assurance about their tap water often start by screening for metals of concern, tungsten among them.
While studies on tungsten in drinking water continue, many Portland residents take a practical, precautionary stance when tests show higher levels. Clear-looking, normal-tasting water can still contain dissolved metals. If your household uses a private well, routine testing helps track changes that may occur with seasons or groundwater shifts. If you’re on a municipal system, checking your local water quality reports and testing at the tap provides a clearer picture of what’s entering your home.
To reduce tungsten at the point of entry, a whole-house reverse osmosis system is generally the most effective single-filter option. Reverse osmosis forces water through a semipermeable membrane that rejects many dissolved metals and inorganic contaminants, lowering tungsten before it reaches faucets, showers, and appliances. Because tungsten exists as dissolved species, it can pass simpler treatments aimed at taste or odor, so a whole-house RO with appropriate prefiltration is recommended to protect the membrane from sediment and chlorine where applicable.
A properly sized whole-house reverse osmosis system can include storage and a delivery arrangement to provide consistent treated water throughout a Portland home. Reliable performance depends on correct sizing, sufficient water pressure, and routine filter and membrane care to prevent fouling that reduces removal. Homes on wells may need extra pretreatment for hardness, iron, or particulates that can shorten membrane life.
