Product Overview
The Jacuzzi® 25 Sq Ft Filter Cartridge (part #2540‑380) is an OEM replacement filter designed for Jacuzzi® hot tubs manufactured before 2002. It uses 25 square feet of pleated filtration media in a closed‑top, blind‑end design, which lets it work with the ProPolish back‑wash filter bags used on select older Jacuzzi® models in addition to standard filtration duty. The pleated construction maximizes surface area within a compact cartridge, so it captures oils, lotions, and fine debris efficiently while maintaining steady water flow through the filtration cycle.
Measuring approximately 10.45″ tall by 5.75″ in diameter with a 2.125″ bottom hole, this cartridge is sized specifically for the filter housings used on pre‑2002 Jacuzzi® spas—later Jacuzzi® models switched to different cartridge dimensions, so this is not a universal fit across the whole Jacuzzi® lineup. It’s also cross‑referenced to several equivalent aftermarket part numbers (Unicel® C‑5601/C‑5300, Filbur® FC‑1330, and Pleatco® PJW23) for anyone comparing options. The cartridge is washable and reusable: rinsing it monthly with a hose and mild detergent helps extend its life between full replacements, which are generally recommended every 6 to 12 months depending on bather load and water chemistry. Using the correct closed‑top, blind‑end design—rather than an open‑bottom cartridge sized for newer Jacuzzi® spas—keeps water flowing through the filter as intended rather than bypassing it.
