Premium Spa Filters for Intex PureSpa

Determining the Right Replacement Cartridge for Your Pool or Spa Already have the part number? Simply enter the filter cartridge's part number or its replacement number into the search bar on our product page to verify compatibility.

Unsure of the part number? Selecting the appropriate cartridge can be achieved by assessing your current one. Follow these steps: 1. Measure the cartridge's external diameter, ensuring accuracy to within +/- 1/16 inch. 2. Measure the cartridge's length from one end cap to the other, excluding any protruding handles or extensions, to within +/- 1/16 inch. 3. Determine the top and bottom type. If they're open, measure the inner diameter of the opening to within +/- 1/16 inch. For closed end caps, note any distinct features (e.g., "Handle", "Cone"). 4. Make a note of the filter's manufacturer and model number where the new cartridge will be placed. 5. Check if there's a central core (like a PP pipe) present.
