Including filter system and high-performance Strontium-90 filter.
Strontium-90 is a radioactive form of strontium that can appear in water at trace levels and moves through groundwater much like calcium does. Because it behaves chemically like calcium, it can dissolve, travel with aquifers, and enter an Old Town house through the main service line. You won’t be able to taste, smell, or see it, so the only reliable way to know if it’s present is a targeted water test for radionuclides.
We use water throughout the home for cooking, ice, bathing, and brushing teeth, so when homeowners in Old Town learn about strontium-90 they’re rightly concerned about whole-house exposure. If testing indicates elevated levels, the simplest way to lower intake is to treat water at the point it enters your home so every faucet and fixture is covered. Point-of-use filters can protect a single tap, but they won’t safeguard showers, laundry, or other outlets—only a properly chosen whole-house system delivers consistent protection across daily household use.
A whole-house water softener using ion exchange is often the most effective single-filter choice for reducing strontium-90 because the resin swaps dissolved ions for sodium or potassium. That ion-exchange process also captures other positively charged contaminants, including chemically identical strontium, so an entry-point softener can lower strontium-90 levels throughout an Old Town residence. For homeowners who want treatment at every tap, an ion exchange system is a practical, proven approach.
To perform reliably for an Old Town household, an ion exchange softener must be sized for your water use and the mineral content coming into your home. Regular regeneration with salt restores the resin so it continues to remove strontium, and routine maintenance preserves long-term performance. Many installations also benefit from prefiltration to keep sediment out of the media. Mr. Pure Water can review your water test and recommend a whole-house softener setup that targets strontium-90 without unnecessary complexity.
