Hayward Replacement Filter Cartridge Set for SwimClear C7030, 4 Pack

The Hayward CX591XREPAK4 is the genuine replacement cartridge set for the SwimClear C7030, the 700 sq. ft. filter in Hayward's SwimClear cartridge line. The C7030 tank holds four elements, and this pack is all four, so one order is one complete reload.

Why the full set

Cartridge filters run best when all the elements load evenly. Swapping the whole set at once keeps flow balanced across the tank and returns the filter to its rated cleaning area instead of pushing water through three tired cartridges and one fresh one.

Before you order

Confirm your filter is the C7030. Other SwimClear sizes use different element sets, so check the model label on the tank before ordering.
