Hydropool 4520007 Spa Filter (PRB50-IN / C-4950 / FC-2390)

Original Hydropool replacement filter cartridge (part 4520007) offering 50 sq. ft. (4.6 m²) of high-efficiency pleated media. Designed for Hydropool spas and swim spas, it is also the direct equivalent of Pleatco PRB50-IN, Unicel C-4950, Filbur FC-2390, and Darlly DRB 50 filters.

Why replace it?

A dirty filter reduces water flow, strains the pump, and increases your sanitizer consumption. Replace the cartridge every 12 to 18 months depending on use, and rinse it every 2 to 4 weeks to extend its lifespan.
