Measure the length, outside diameter and end cap type of your old cartridge, or match the part number printed on its end cap.\u003c\/p\u003e\u003ch3\u003eWhat is the difference between cartridge, sand and D.E. filters?\u003c\/h3\u003e\u003cp\u003eCartridge filters trap particles in pleated media and need no backwashing. Sand filters are lowest maintenance but filter to a coarser level.

Cleaning too often on a cartridge shortens its life; waiting too long strains the pump.\u003c\/p\u003e\u003ch3\u003eHow do I confirm this part fits my equipment?\u003c\/h3\u003e\u003cp\u003eCheck the part number stamped on the component you are replacing, or find it on the parts schematic in your owner's manual.
