Filter matching
How filter matching works.
Start with the model or part number, then compare the old cartridge’s size and end caps.
1. Search the full number
Enter the complete equipment model or cartridge part number, including letters, dashes, and zeros. A brand name by itself is usually not enough.
2. Compare the old cartridge
Check the outside diameter, cap-to-cap length, top, bottom, opening size, and number of cartridges required.
3. Measure when the number is shared
Some part numbers appear on more than one cartridge shape. When that happens, use the measurements and end caps to tell them apart.
