The Unicel C-4312 R Compatible Pool & Spa Filter Cartridge, also known as the Filbur FC-1210, is a replacement spa and pool filter cartridge produced to exact OEM specification – no pool filter pad adapters needed. This filter replaces the Aladdin 11204 and Pleatco PA12.

The compatible Unicel C-4312 swimming pool filter delivers its trusted build and performance quality. Made with genuine Reemay filter media – spunbond polyester which is resistant to fraying and unraveling and won’t react to the chemicals found in your pool or spa - reinforced and extruded PVC center core and break-resistant bands, this spa filter will continuously deliver durability and consistent flow. Plus its reinforced antimicrobial end caps mean less cleaning and fewer replacements, through actively repelling the build-up of bacteria, fungi, mold and mildew, which all reduce the efficiency of your system.
