The Unicel C-4637 R Compatible Pool & Spa Filter Cartridge, also known as the Filbur FC-2380, is a direct replacement spa and pool filter cartridge designed to exact OEM specification – no need for pool filter pad adapters. This filter replaces the Aladdin 13701 and Pleatco PRB37-IN-4.
The compatible Unicel C-4637 R swimming pool filter delivers its trusted filtration quality. This filter’s reinforced antimicrobial end caps actively repel the build-up of bacteria, fungi, mold and mildew, meaning less cleaning, fewer replacements and improved efficiency. This Filbur filter benefits from genuine Reemay filter media – spunbond polyester, which resists unraveling, fraying and won’t react to your pool or spa’s common chemicals. This spa filter also uses reinforced and extruded PVC center core and break-resistant bands for extra durability.
