How to identify your pool and spa filter cartridge?
If you already know your filter cartridge's part number, please search the part number on our product page to quickly confirm whether the filter is compatible.
If you do not know the part number for your cartridge, then choosing the right cartridge can be accomplished by measuring your existing one. Use the following steps as a guide:
- Measure the outside diameter of the cartridge.(±1mm).
- 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.
- If the top and/or bottom is open, measure the inside diameter of the opening (±1mm). If the end cap is closed make note of its identifying features (i.e. 'Handle', etc.).
- Make note of the manufacturer (OEM) and model number of the filter into which the replacement cartridge will be installed.
- Take note whether or not there is a center core.Also count the number of pleats (±2).

Perfect fit and work great. Good price for a (3) pack. Better then buying special chemicals and cleaning old filters.
