Replacement Cartridge for Hayward C900 and CX900RE

This 90 sq ft filter cartridge replaces the Hayward C900 and CX900RE models. It also cross-references Pleatco PA90 and Unicel C-8409. The part is a third-party compatible accessory built to match original equipment dimensions and flow characteristics.

90 sq ft Filtration Area with 50-micron Precision

The cartridge provides a total filtration area of 90 sq ft using trilobal pleated fiber media rated at 50-micron filtration precision. This specification determines the dirt-holding capacity and the particle size the filter can capture before cleaning is required.

Fits 4 in Core Openings with 17.4 in Height

The filter core has a 101.6 mm inner diameter (4 in) and a 442 mm height (17.4 in), requiring a housing that accepts those dimensions. The trilobal pleated design with 174 folds maximises surface area inside the existing canister, freeing up no additional plumbing space while maintaining backpressure stability.

Questions about this item

How much water can a 90 sq ft cartridge actually filter before it needs cleaning?

The 90 sq ft filtration area gives high dirt-holding capacity, so the cartridge traps hair, leaves, dust and fine particles down to 50 microns for longer cycles between cleanings.

What pump pressure does the 50-micron trilobal fiber limit in practice?

The trilobal pleated fiber is designed to enhance system backpressure stability while capturing particles at 50 microns, keeping flow steady through the filter.

Will the 17.4 in length and 8.9 in diameter fit my Hayward C900 housing?

Yes, the cartridge measures 17.4 in long with an 8.9 in outer diameter and a 4 in core inner diameter, matching the Hayward C900 and CX900RE specifications.
