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:

1. Measure the outside diameter of the cartridge in inches (+/- 1/16th inch)

2. Measure cartridge length from end cap to end cap (+/- 1/16th inch). Exclude any handles or extensions.

3. Identify the correct top and bottom type. If the top and/or bottom is open, measure the inside diameter of the opening (+/- 1/16th inch). If the end cap is closed make note of its identifying features.

4. Make note of the manufacturer and model number of the filter into which the replacement cartridge will be installed.

5. Take note whether or not there is a center core (PVC pipe in center).

I ordered the wrong one. I guess so I can’t really review this. Looks like it’s built very well though.

Perfect fit for our hot tub. The pool supply stores didn't carry what we need, happy I found on Amazon and much cheaper.

It will work with my hot tub but it is not a perfect fit. It works well enough that I am not going to return it. I will order another brand when this one is due to be replaced.

My filter was 13" even. Those are hard to find and wxpensive. The extra 5/16 did not hurt at all. It fits perfectly! So much cheaper!

The filter is an exact replacement and appears to be well made. I haven't had to clean it yet since it has only been in a few days, so I gave 4 stars for cleaning. I'm sure it will be fine.
