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).

Hot tub filter replacement. Price was very reasonable

I was so excited to find this filter for my hot tub. It’s a little cheaper than the ones I have previously purchased and so I was a little concerned about that. But so far it has done a fantastic job. I do remove the filter approximately every two weeks and rinse it out with the jet stream function of my water hose. Very economical and perfect for replacing filters in your hot tub!
