About This Item
The Unicel 4000 Series C-4320 delivers 20 sq. ft. of filtration surface area through 110 precision pleats of 3 oz. Reemay 2033 spun-bonded polyester — engineered as a direct replacement for Hayward and American Products in-line filter systems. The increased pleat density maximizes debris capture and extends cleaning intervals, keeping your pool water clear with consistent flow and pressure performance.
⚠️ IMPORTANT: OEM DIMENSIONAL DIFFERENCE
The Hayward CX200RE original measures approximately 4-3/4" OD × 11-13/16" length, and the American Products 57010200 original measures approximately 4-11/16" OD. The Unicel C-4320 (4-5/8" OD × 11-7/8" L) is precision-engineered as a direct replacement for both — minor dimensional variations are normal for aftermarket cartridges and do not affect fit or performance within the filter housing.
