Including filter system and high-performance Strontium-90 filter.
Strontium-90 is a radioactive form of strontium that can occur in water at very low concentrations. Because it acts much like calcium, it can dissolve into groundwater and travel through distribution lines to reach a home’s main supply. There’s no reliable taste, smell, or color to signal its presence, so the only way to know if your Felkel water contains it is with targeted radionuclide testing performed on your water sample.
Families in Felkel use their water for many everyday tasks—cooking, making ice, bathing, and brushing teeth—so any contaminant detected in testing can affect the whole household. If tests show elevated strontium-90, reducing exposure means treating water at the point it enters the home so every faucet and appliance is covered. While point-of-use devices help one sink, a properly selected whole-house system gives consistent protection across all fixtures in your house.
A whole-house water softener using ion exchange is often the most effective single-filter option for reducing strontium-90 because the resin exchanges dissolved ions for sodium or potassium. That ion-exchange process also captures other positively charged contaminants, including strontium, so chemically similar elements can be reduced as water passes through the tank. For Felkel homeowners who want treatment at the entry point, an ion exchange softener is a practical, widely used choice.
To perform reliably in a Felkel home, an ion exchange softener should be sized based on your household water use and the hardness or mineral content of your water. Routine regeneration with salt restores the resin’s ability to remove strontium, and regular maintenance helps maintain consistent performance. Prefiltration is often recommended to protect the resin from sediment, and Mr. Pure Water can review your test results and recommend a whole-house configuration that targets strontium-90 without adding unnecessary complexity.
