So Clean. So Clear. So Easy. The Sand Dollar filter is the perfect high-performance sand filter. It’s incredibly simple to operate and maintain, and it’s built with long-term reliability in mind. Plus, its highly efficient design provides all the clean, crystal-clear water your pool requires year after year. Pool water is routed through the sand-filled pressure vessel. The sand traps particles so small they are undetectable to the naked eye. Over time, dirt accumulates in the spaces between the sand particles, causing the pressure in the vessel to rise. This signals you to “backwash” the filter by simply reversing the water flow and “knocking out” the dirt.
