Filter Measurements Not FoundUpdated a year ago

Our Pool Filter Cartridge Collection has an 2 minute Find-My-Filter Quiz that will recommend the correct replacement pool filter cartridge based on the Length, Width, and Hole size of your current filter (measurements are in millimetres).

If no results are found from the quiz, please contact us with the following details in order to help us to identify what replacement you need:

1. Existing filter brand and model number.
2. Photos of your existing filter; everything from the housing, lid and cartridge.
3. Dimensions of the filter cartridge element; length, width and hole width in millimetres. More details on how to properly measure your cartridge below.

The more of these details you have, the easier it will be for us to assist you.

How To Properly Measure Your Filter Cartridge Element

Yes, this involves taking your old cartridge out of its housing and measuring it with a tape measure.
These dimensions are listed in the description of each and every one of our filters.

Overall Length

Measure through the inside hole from one side to the other, this will ensure any small lips around the hole are included in the measurement, which may change the length.

Diameter

Measure the top of the filter directly from one side to the other.

Hole Diameter

Measure the filter hole from one side to the other.
