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.

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.
