Unicel C-7472-4

The Unicel C-7472-4 is the four-pack of the C-7472 replacement cartridge for the Pentair Clean & Clear Plus 520 filter system.

C-7472-4 is the Unicel part number for the four-pack of the C-7472 cartridge, which fits the Pentair Clean & Clear Plus 520, the largest filter in the line. The suffix -4 means a set of four. The CCP520 takes four cartridges, so the four-pack is the standard order.

Specifications

Length	32 1/16 in
Outer diameter	7 in
Top opening	3 in
Bottom opening	3 in
Filtration area	130 sq ft
System total	520 sq ft (four cartridges)
Media	4 oz polyester

These are the specs of each of the four cartridges in the pack. The set totals 520 sq ft.

Why the four-pack is the standard order

The Clean & Clear Plus 520 holds four cartridges. They wear together and reach the end together, so the whole set gets replaced at once. C-7472-4 is the packaged four.

Keeping all four the same age matters. One fresh cartridge among three worn ones takes uneven load and wears early.

How to verify the four-pack is right for you

If your cartridge reads C-7472, or any equivalent, and your filter is a Clean & Clear Plus 520, the C-7472-4 four-pack is correct. Confirm by dimension if the cap is worn: 32 1/16 inches long, 7 inches across, 3 inch openings at each end.
