Including filter system and high-performance Strontium-90 filter.
Strontium-90 is a radioactive form of strontium that can occur at very low concentrations in water. Because it acts like calcium, it travels with groundwater and can enter houses through the main service line without any change in taste, smell, or color to warn you. The only reliable way to confirm its presence is a lab test that looks for radionuclides, so Key West homeowners should consider targeted testing if they have concerns.
In a home, water is used for many everyday tasks — drinking, cooking, making ice, bathing, and brushing teeth — so any contaminant found in supply water affects the whole household. Point-of-use devices protect a single fixture, but they leave the rest of the house exposed. For Key West properties, from Old Town cottages to newer builds in New Town, a whole-house system treated at the entry point gives consistent protection across all faucets and appliances.
A whole-house water softener that uses 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. That same exchange process can capture positively charged contaminants like strontium, so an ion exchange softener installed at the home’s main line treats water before it reaches showers, sinks, and appliances in Key West.
To be effective in Key West’s conditions — with moderate hardness and coastal salt air that can affect plumbing — an ion exchange softener should be sized for your household’s water use and mineral load. Regular regeneration with salt restores the resin’s capacity to remove strontium, and routine maintenance plus prefiltration helps keep sediment from fouling the media. Mr. Pure Water can review your test results and recommend a whole-house configuration that targets strontium-90 while fitting island living and local needs.
