How does the EcoOne Pre-filter work and when should I use one?
The EcoOne Pre-filter removes metals and other contaminants from your source water by filtering the water through a granular activated carbon (GAC) and a reduction/oxidation media. In the case of calcite, the filter will change the molecular structure of the mineral so that the mineral stays suspended in the water, instead of clouding the water. The Pre-filter was created for people with well water or water systems that contain heavy metals and / or other contaminants. Using the Pre-filter when filling your spa will reduce the contaminants in the water in your spa and result in fewer water quality issues. The Pre-filter is most effective at removing contaminants when filling at low rates of flow (1 or 2 gallons per minute), so it will take some time to fill a large spa.
