Unicel C-7471-4

The Unicel C-7471-4 is the four-pack of the C-7471 replacement cartridge for the Pentair Clean & Clear Plus 420 filter system.

C-7471-4 is the Unicel part number for the four-pack of the C-7471 cartridge, which fits the Pentair Clean & Clear Plus 420. The suffix -4 means a set of four, not a different cartridge. The CCP420 takes four cartridges, so the four-pack is the standard order.

Specifications

Length	26 1/16 in
Outer diameter	7 in
Top opening	3 in
Bottom opening	3 in
Filtration area	105 sq ft
System total	420 sq ft (four cartridges)
Media	4 oz polyester

These are the specs of each of the four cartridges in the pack. The set totals 420 sq ft.

Why the four-pack is the standard order

The Clean & Clear Plus 420 holds four cartridges. They wear at the same rate and reach the end together, so replacing the whole set at once is correct. C-7471-4 is the packaged four for that job.

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

How to verify the four-pack is right for you

If your cartridge reads C-7471, or any equivalent, and your filter is a Clean & Clear Plus 420, the C-7471-4 four-pack is correct. Confirm by dimension if the cap is worn: 26 1/16 inches long, 7 inches across, 3 inch openings at each end.
