Replacement Filter Measuring Guide & End Caps

  1. Measure the outside diameter of the cartridge (in inches, +/- 1/32”).
  2. 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.
  3. Identify the cartridge outside edge end cap
    configuration using the chart on the opposing page. If the top and/or bottom is “open,” measure the inside diameter (in inches, +/- 1/32”) of the top and/or bottom.
  4. Record the OEM name and model of the filter the cartridge came out of (if possible).
  5. Count the number of pleats (+/- 2) and note
    whether there is a center core or not.
