How to Determine the Right Replacement Cartridge for Your Pool or Spa?
Already have the part number!
Simply input the filter cartridge's part number or its replacement number into the search bar on our product page to verify compatibility.
Unsure of the part number!
Selecting the appropriate cartridge can be achieved by assessing your current one. Follow these steps:
1. Gauge the cartridge's external diameter, ensuring accuracy to within +/- 1/16 inch.
2. Measure the cartridge's length from one end cap to the other, excluding any protruding handles or extensions, to within +/- 1/16 inch.
3. Determine the top and bottom type. If they're open, measure the inner diameter of the opening to within +/- 1/16 inch. For closed end caps, jot down distinct features (e.g., "Handle", "Cone").
4. Note down the filter's manufacturer and model number where the new cartridge will be placed.
5. Check if there's a central core (like a PP pipe) present.

Product is as described, and seem well-made. It's helpful to change/clean your filter regularly, so having a few extra for the season is excellent.

This is a great set of filters for our pool pump that requires size B filters. These lasted a long time and worked well keeping our pool clean!

I purchased a new, more powerful pump for my above ground pool. These filters are great but as with any filters, you have to check and change often. I like these filters because I can just wash them and get several more uses out of them. I will wash and reuse them 4 or 5 times before I toss them out. Depending on how dirty the water gets of course. I have gotten as many as 10 uses out of one filter before I thought it was not coming clean anymore. Easy to install and a great value!

These fit well and work comparably to the name brand cartridge filters. Nice replacement filters for the price.
