The Purhome Hard Water Conditioner uses a catalyst media called Filtersorb SP3® to transform dissolved calcium and magnesium carbonate into calcite crystals, which are carried away in the water flow.
The system is designed for water with up to 25 grains of hardness per gallon. The conditioners are advertised as maintenance-free, but you do have to replace the filter media periodically. Puriteam guarantees Purhome Hard Water Conditioners for 5 years or 600,000 gallons.
Purhome softeners are sold through local dealers and online retailers like Amazon.com. You can also purchase through Puriteam’s website.
