How To Find A Replacement Cartridge For Your Pool Or Spa


A. Measure the outside diameter of the cartridge in inches (+/- 1/16)

B. Measure the overall length of the cartridge in inches (+/- 1/16), including the end caps. Do not include any handles, strings, etc. A more accurate measurement is made by measuring through the center of the cartridge when possible.

C. If the top and/or bottom is open, measure the inside diameter of the opening (+/- 1/16 inch). Match the cartridge end cap configuration to either a corresponding one on the page or the complete end cap gallery (page #5).

D. Make note of the manufacturer (OEM) and model number of the filter the replacement cartridge will be installed.

E. Take note whether or not there is a center core (PVC pipe in center). Also count the number of pleats (+/- 2).
