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 mimics calcium chemically, it moves with groundwater and can enter a house through the main service line without any telltale taste, odor, or color. The only reliable way to know if it’s present in your Bertha water is to test specifically for radionuclides using a qualified lab.
You use your home’s water for much more than drinking—cooking, ice, bathing and brushing teeth all involve the same supply. While a point-of-use filter can treat a single faucet, it won’t protect showers, laundry, or all household uses across a Bertha property. If tests for strontium-90 show elevated levels, treating at the point where water enters the house with a whole-house system gives broader, consistent protection for everyday use.
A whole-house water softener using ion exchange is often the most effective single-filter option for reducing strontium-90 because the resin swaps certain dissolved ions for sodium or potassium. Since strontium behaves like other positively charged minerals, the resin can capture it through the same exchange process. For many Bertha homes on hard, limestone-influenced groundwater, an ion exchange softener treats incoming water at the entry point and addresses both hardness and strontium at once.
Sizing an ion exchange softener to match your household’s water use and mineral content is key to reliable performance. Regular regeneration with salt restores the resin’s ability to remove strontium over time, and routine maintenance prevents issues. In Bertha, where hard water and scale are common, pairing a softener with prefiltration helps protect the media from sediment and extends its life—Mr. Pure Water can review your test results and recommend the right whole-house setup.
