Pentair 179136
The Pentair 179136 is the complete set of four replacement pool filter cartridges for the Clean & Clear Plus 520 filter system.
179136 is the current Pentair part number for the complete set of four cartridges that fit the Clean & Clear Plus 520. Use this number for the whole factory set rather than a single. Each of the four cartridges in a 179136 set is individually an R173578.

How to verify this is the right cartridge
179136 is an OEM set number, usually on packaging or an order rather than the cartridge. The individual cartridges carry R173578 or the older 178585. If your filter is a Clean & Clear Plus 520 and you want the factory set, 179136 is correct.
To confirm from the equipment, measure one cartridge: 32 1/16 inches long, 7 inches across, 3 inch openings at both ends.
How many cartridges does my filter take
The Clean & Clear Plus 520 uses four cartridges, which is what a 179136 set provides. Buying the set means all four are the same age and wear evenly.
