Replacement Pool Filter Cartridges for Swimming Pools & Spas
Swimming Pool / Spa Filter Cartridges listed by the Filter Manufacturer
Trying to find the correct replacement cartridge for your swimming pool or spa can be quite confusing. Filter cartridges come in a vast array of sizes, and the tops and bottoms of cartridges come in a variety of configurations. Our goal is to make it as easy as possible for you to determine the right filter cartridge for your particular swimming pool or spa. We currently offer filter cartridges for more than 1,500 pool and spa filter models, so you're sure to find what you need here.
If you already know your filter cartridge's part number or the Unicel, Pleatco, or Filber replacement number, you can use the search box at the top right on this page (above our phone number) to quickly locate your cartridge. Or, you can follow one of the manufacturer's links below for a list of replacement cartridges for filters made by that manufacturer.
Measuring Your Filter Cartridge
If you do not know the replacement 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 end caps. Use exact measurement (+ or - 1/16th inch).
- Measure cartridge length from end cap to end cap (+ or - 1/16th inch). Exclude any handles or extensions.
- Measure the top inside diameter. Use exact measurement (+ or - 1/16th inch).
- Measure the bottom inside diameter.
- Note the name and model of the filter from which the cartridge came out, if available.
- Identify the correct top and bottom type.
Diagrams for each of these steps in the cartridge identification process can be found in our Guide to Identifying Your Filter Cartridge.
Before making your final filter cartridge selection, double check the cartridge dimensions against the one that you wish to replace. If you have any questions or concerns about the cartridges, or if you are having difficulty identifying the type of cartridge you need, please don't hesitate to email us or give us a call. We'll get you an answer quickly.
Cleaning Your Filter Cartridge
Filter cartridges are most often made with either polyester cloth or corrugated paper. As dirty water passes through the filter material, it captures dirt and debris to help pool and spa water stay clean. Over time, this dirt and debris build up on the filter and can clog the filter material. With proper maintenance, though, a high-quality filter cartridge can last for several years.
