Standard sand filter

Sand filters are one of the most popular ways to filter water. They are simple, effective and require very little attention. Pool water is routed through a sand-filled pressure vessel. The sand traps particles large and small… But not all sand filters are created equal. Through innovative engineering, the Cristal-Flo filter’s dirt-handling capacity is maximized, which extends the time between cleanings (backwashing). But best of all, the Cristal-Flo is new also available with ClearPro Technology® to make your pool water sparkle in the sun and shimmer in the moonlight.
