Part reference
Pentair 179135
The Pentair 179135 is the complete set of four replacement pool filter cartridges for the Clean & Clear Plus 420 filter system.
179135 is the current Pentair part number for the complete set of four cartridges that fit the Clean & Clear Plus 420. Use this number when you want the whole factory set rather than a single cartridge. Each of the four cartridges in a 179135 set is individually an R173576, the Pentair single.

How to verify this is the right cartridge
179135 is an OEM set number, usually found on packaging or an order rather than molded on the cartridge. The individual cartridges carry R173576 or the older 178584. If your filter is a Clean & Clear Plus 420 and you want the factory set, 179135 is the correct order.
To confirm from the equipment, measure one cartridge: 26 1/16 inches long, 7 inches across, 3 inch openings at both ends.
How many cartridges does my filter take
The Clean & Clear Plus 420 uses four cartridges, which is what a 179135 set provides. Buying the set means all four are the same age and wear evenly.
