Including filter system and high-performance Radium filter.
Radium is a naturally occurring radioactive metal that can show up in groundwater and, in some areas, in residential drinking water. Homeowners usually can’t see, smell, or taste it, which is why testing is the best way to know what’s coming out of the tap. In water reports and lab results, you may also see it listed as radium-226 or radium-228. When levels run high, many homeowners look for a treatment approach that protects every faucet, not just the kitchen sink.
Radium can dissolve into water as it moves through certain rock and soil formations, so its presence is tied to local geology more than to daily household use. Because it behaves like other minerals, it may travel alongside hardness or other dissolved solids, even when water looks perfectly clear. If you’re concerned about long-term exposure, it helps to treat the water at the point it enters the home. A whole-house system can reduce radium throughout the plumbing while keeping water quality consistent for drinking, cooking, and bathing.
For radium reduction at the whole-house level, an ion exchange water softener is often the most effective single-filter style option. This type of system uses resin beads that swap sodium or potassium ions for certain dissolved minerals in the water, and radium can be captured in the same process. It’s a strong fit when radium is present as a dissolved contaminant rather than attached to sediment. Installed on the main line, it treats all water entering the home, which helps ensure consistent protection at every tap.
Because an ion exchange system has a finite capacity, proper sizing and maintenance are key to reliable radium removal over time. The resin must be regenerated regularly, and the settings should match your water chemistry and household demand so the media doesn’t exhaust early. Many homes also benefit from prefiltration for sediment to protect the resin and keep flow steady. Mr. Pure Water can help select and set up a whole-house ion exchange solution that targets radium-226 and radium-228 while fitting your home’s plumbing and water use.
