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).

I have had a hot tub since 1998. Catalina and replaced with a new Catalina in 2022. Always used paper filters, these new plastic woven fibered filters are the bomb!

When we originally bought our spa we bought a very pricey filter at the spa store. When it came time to replace it I didn’t want to spend an arm and a leg for a filter that doesn’t last all that long. I went on Amazon and found this brand and decided to give it a try. This filter exceeded my expectations and I feel like it is actually much better than the one I bought at the spa store. It fit perfectly the first time and was easy to install and you get two for less then the name brand ones which is even better! I highly recommend these!

These are excellent filters for your hot tub. Perfect fit and sturdy enough to clean and reuse. I use a filter cleaner to soak them in when I replace with the second one and they clean nicely. My second purchase.

The pictures on Amazon do the product justice. These filters are a good value for the price. They help keep my spa water clean and install easily. They are good for one rinse provided they are not too dirty.
