How to find a replacement cartridge for your pool or spa?
If you already know your filter cartridge's part number or the replacement number, you can use the search the part number on our product page to quickly confirm whether the filter is compatible.
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 cartridge in inches (+/- 1/16th).
- Measure cartridge length from end cap to end cap (+/- 1/16th). Exclude any handles or extensions.
- Identify the correct top and bottom type. If the top and/or bottom is open, measure the inside diameter of the opening (+/- 1/16th). If the end cap is closed make note of its identifying features (i.e. “Handle”, “Cone”, etc.).
- Make note of the manufacturer and model number of the filter into which the replacement cartridge will be installed.
- Take note whether or not there is a center core (PVC pipe in center).

Perfect fit & 1/2 the price compared to the pool stores. Make sure you measure the old one to make sure it fits. Length & width of the hole.

As filters go, there are only a few criteria: Does it filter out particles well? Does it clean easily? Does it last a long time with proper care?Yes to all 3. Couldn’t be happier with the performance of this filter. I’ve had about 6 of these so far and none have been faulty.

Fit nice and snug in my pool filter does a great job keeping my pool clean. Rinsing it is a bit of a job but that just means it’s doing its thing!
