They utilize a precision engineered umbrella-fold self-cleaning lateral system to provide efficient flow and evenly distributed water for long lasting performance. A broad selection of filter sizes, pumps, and accessories allows you to choose the system that best suits your above-ground pool needs.

    Superior filtration from the inside out
    The ProSeries filter features an integral top diffuser that evenly distributes unfiltered water over the sand media bed in a cascading, umbrella-like pattern. This allows the greatest filtration possible from every square inch of sand. Then the self-cleaning underdrain assembly, with its 360 deg slotted laterals, provides a fast, balanced flow of clear water back to the pool while allowing for more thorough backwashing. Best of all, the ProSeries full-flow technology reduces your energy costs because the filter operates for shorter periods.
    Seven-position valve puts you in control
    The patented, multiport control valve developed by Hayward was designed with seven pool filter positions. An easy-to-use lever-action handle lets you quickly dial any function.
    Long-lasting convenience
    You can easily access the ProSeries filter assembly for simple servicing via the unique folding ball joint in the laterals. A corrosion-proof housing protects the filter from severe weather for years to come.
