This sand filter for pools includes an integral top diffuser capable of evenly distributing unfiltered water in an umbrella-shaped, cascading pattern over its sand media bed-this enables optimal filtration from each sq. in. of sand. From there, the auto-cleaning underdrain, outfitted with 360-degree slotted laterals, channels a quick-flowing, balanced stream of clean water back into the pool while permitting fuller backwashing. What’s more, the filter’s full-flow design lowers energy expenses because it allows the system to operate for shorter durations.
