Hayward Star-Clear 50 square foot cartridge filters provide crystal clear water and have extra cleaning capacity for pools up to 12,000 gallons.

An extra-large cartridge element with new precision engineered extruded core provides extra-strength and maximum flow. An elevated, filtered water collector and debris sump prevents accidental by-pass of heavy debris to pool or spa when cartridge is removed for cleaning.
