The filtered capacity and change-out cycle depends on the inlet water quality. Replace the filter at least every six months to maintain performance. HIGHER DIRT-HOLDING CAPACITY: The string wound filter has a deep graded honeycomb structure, dense near the inside core and more open and sparse near the outside edge, forming an effective depth filtration filter, catching larger particulates first and then smaller near the center core, effectively increasing the dirt holding capacity of the filter.
