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 travels with groundwater and can enter a home through the main supply line without changing taste, smell, or color. The only reliable way to detect it is with a water test that looks specifically for radionuclides, something we often help Fidelis homeowners arrange.
You use household water for much more than drinking—cooking, ice, bathing, and oral hygiene all rely on your plumbing. If testing identifies elevated strontium-90, the practical step is to reduce exposure by treating water at the point it enters the house so every fixture is protected. Point-of-use filters can guard a single tap, but they won’t cover showers, washers, or outdoor hose bibs; many Fidelis residents choose a whole-house option for consistent protection across daily water use.
A whole-house water softener using ion exchange is often the most effective single-filter approach for reducing strontium-90 because the resin swaps certain dissolved ions for sodium or potassium. That same exchange process can capture positively charged contaminants like strontium, so installing an ion exchange softener at the entry point treats water for the entire home. For homeowners in Fidelis, this makes an ion exchange system a practical choice when addressing strontium concern across every tap.
To be effective, an ion exchange softener needs to be sized for your household’s water use and overall mineral load, and it requires regular regeneration with salt to restore the resin’s capacity to remove strontium. Maintenance and proper prefiltration protect the media from sediment and prolong performance. Mr. Pure Water can review your Fidelis test results and recommend a whole-house softener setup that targets strontium-90 while keeping the system simple and reliable.
