Including filter system and high-performance Strontium-90 filter.
Strontium-90 is a radioactive form of strontium that can appear in water at very low concentrations. Because it acts like calcium chemically, it can travel with groundwater and enter your Harp house through the main line. There’s no reliable taste, smell, or color to signal its presence, so the only way to know if it’s in your water is with testing focused on radionuclides.
In Harp households, the water you use for cooking, making ice, bathing, and brushing teeth is the same supply that could carry strontium-90. If tests show elevated levels, the practical approach is to treat water at the point it enters the home so every faucet and fixture is covered. Point-of-use devices protect only a single tap; a correctly chosen whole-house system gives consistent protection across all daily uses.
A whole-house water softener using ion exchange is commonly the most effective single-filter option for reducing strontium-90 because the resin swaps certain dissolved ions for sodium or potassium. That same exchange can capture positively charged contaminants like strontium, so an ion exchange softener can reduce chemically identical strontium-90 as water flows into your Harp home. For many homeowners, this makes an entry-point softener a practical choice when broad coverage is the priority.
To be effective in Harp, an ion exchange softener should be sized to your household’s water use and overall mineral load. Regular regeneration with salt restores the resin’s ability to remove strontium, and routine maintenance helps keep performance consistent. Prefiltration to remove sediment often extends media life, too. Mr. Pure Water can examine your water test results and recommend a whole-house configuration that targets strontium-90 while keeping the system straightforward and reliable.
