How to Find a Unicel Replacement Filter for your Hayward Cartridge Filter
  • Measure the outside diameter of the cartridge (in inches, +/- 1/32").
  • Measure the cartridge length (in inches, +/- 1/16) including end caps but excluding any handles or other extensions. Unicel recommends measuring through the center (if possible) rather than along the outside edge.
  • Identify the cartridge outside edge end cap configuration using the photograph chart below. If the top and/or bottom is "open," measure the inside diameter (in inches, +/- 1/32) of the top and/or bottom.
  • Record the OEM name and model of the filter the cartridge came out of (if possible).
Unicel cartridges are grouped into series based on the approximate outer diameter (O.D.) of the cartridge. For example, the 2000 Series is comprised of cartridges between 2 and 2.99 inches in outer diameter; the 9000 Series is comprised of cartridges with an outer diameter of 9 inches or greater. Note that if the cartridge length is either 4-15/16 or 6-15/16 it may be necessary to check the next larger series, the 5000 Series and 7000 Series, respectively. Within each series, cartridges are listed sequentially by O.D. and cartridge length and identified according to end cap i.d. and configuration, pleat count, media, and respective OEM. Some Unicel cartridges are interchangeable.
