Filter Cartridges - Identify your Cartridge

Method One: Look for the Part Number On the End-Cap

Pleatco end-caps show the part number for easy identification.

Look on the end cap for the Pleatco part number, which is easily cross-referenced with OEM filter cartridge part numbers, or generic cartridges made by Filbur, Aladdin or Unicel.

Method Two: Measure the Filter Cartridge

Measure the outside diameter of the cartridge.

Measure the overall length of the cartridge 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.

If the top and/or bottom is open, measure the inside diameter of the opening.

Method Three: Manufacturer Part Number


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


Take note whether or not there is a center core in center. Also count the number of pleats.

Note: Filter measurements may vary. Allow a variance of: +/- 1/16 in. or +/- 2 mm
