Hayward 150 Sq. Ft. SwimClear Cartridge Element, CX150XRE

The Hayward CX150XRE is the genuine replacement cartridge element for the SwimClear C150S filter. It carries 150 sq. ft. of filter area and measures 10-1/4 in. in diameter, so it drops into the C150S tank without adapters.

Cross references

The same position is filled by Unicel C-9441, Hayward CS150E, Pleatco PA150S and Filbur FC-1266. If your old element carries one of those numbers, this is the OEM equivalent.

Why the OEM element

Hayward builds its cartridges to match its own filters, which keeps the hydraulic efficiency of the tank where it was designed to be and holds up to repeated cleaning. A cartridge filter also catches finer material than a sand bed, and there is no backwashing to send water down the drain.

When to replace

Pressure that climbs again soon after a cleaning, pleats that will not come clean, or torn or collapsed media all mean the element is done. Fitting a new one restores flow and takes the strain off the pump.
