How to Measure a Pool Filter CartridgeUpdated a year ago

If you have the specific model of your cartridge filter, let us know so we can recommend a suitable replacement. 

If you do not know your current make and model of your filter, you need to take three measurements into account: 

• Overall Length

• Diameter

• Hole Diameter

Overall Length x Diameter x Hole Diameter

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.

Send us the measurements plus photos of your existing filters and we can get you on the right track with the right filter replacement.
