How to find the right cartridge
The fastest route is the model number printed on your old cartridge’s end cap — type it into the search box above. If it’s worn off, search by your filter housing (for example “Hayward C900” or “Intex”), or match the square footage and nominal dimensions.
OEM vs. aftermarket (Pleatco / Unicel / Filbur)
Pleatco, Unicel, and Filbur make aftermarket cartridges that cross-reference to the original manufacturer part. They typically cost less and fit the same housing. Dimensions are nominal and end-cap styles can vary slightly, so always confirm size and hole pattern before ordering.
