Including filter system and high-performance Radium filter.
Radium is a naturally occurring radioactive metal that can show up in groundwater and sometimes in household drinking water; you won’t be able to see, smell, or taste it, so testing is the only way to know what’s in your tap. On lab reports it may appear as radium-226 or radium-228. Many Marathon Shores homeowners choose treatments that protect every faucet — not just the kitchen sink — especially given coastal corrosion and storm-related plumbing risks in the Florida Keys.
Because radium dissolves from certain rock and soil as water moves through local geology, its presence relates more to source conditions than household activity. It often travels with other dissolved minerals, including the hard water common around Marathon Shores, so water can look clear while still carrying contaminants. For long-term peace of mind, treating water where it enters the home with a whole-house system keeps radium reduction consistent for drinking, cooking, and bathing across every tap.
An ion exchange water softener is often the best single-filter choice for reducing radium at the whole-house level. These systems use resin beads to swap sodium or potassium for dissolved minerals, and they can capture radium in the same process. When radium is present dissolved in water rather than bound to sediment, an ion exchange softener installed on the main line treats all incoming water and helps maintain consistent protection throughout a Marathon Shores home.
Ion exchange systems have limited capacity, so correct sizing and regular maintenance are essential for reliable radium removal over time. The resin requires periodic regeneration and system settings should match your water chemistry — including the hard water typical in the Keys — and household demand to avoid premature exhaustion. Prefiltration for sediment can protect the resin and preserve flow; Mr. Pure Water can help select and install a whole-house ion exchange solution tailored to Marathon Shores plumbing and to target radium-226 and radium-228.
