Including filter system and high-performance Tungsten filter.
Tungsten is a naturally occurring metal that can show up in drinking water at low levels. It can enter groundwater through contact with certain rock and soil types or nearby industrial influences, and because tungsten is typically colorless and odorless you won’t detect it without lab testing. Littman homeowners who want peace of mind often begin by checking for metals of concern, including tungsten, so they know exactly what’s in their tap water.
While research on tungsten in drinking water is still developing, many Littman residents choose a cautious approach when tests indicate higher concentrations. Clear, normal-tasting water can still contain dissolved metals, so routine testing is a good idea—especially for private wells, where seasonal changes and usage patterns can alter water quality. If you receive municipal service, reviewing the local water quality report and confirming results with a tap test helps verify what’s entering your Littman home.
To reduce tungsten at the point of entry, a whole-house reverse osmosis system is generally the most effective single-filter solution. RO employs a semipermeable membrane that rejects many dissolved metals and inorganic contaminants, lowering tungsten before water reaches faucets, showers, and appliances in your Littman house. Because tungsten is present as dissolved species, it can pass through simpler media designed for taste or odor, so a properly configured whole-house RO—with prefiltration to protect the membrane from sediment and chlorine where needed—is the preferred option.
A whole-house reverse osmosis setup can include storage and a delivery system to provide consistent treated water throughout a Littman home. Long-term performance depends on right-sizing the system, maintaining adequate pressure, and performing scheduled filter and membrane maintenance to prevent fouling. If your property uses a well, additional pretreatment for hardness, iron, or particulates may be advised to extend membrane life.
