About this spa filter cartridge

Clarathon FC-2375 Spa Filter (replaces Pleatco PRB25-IN / Unicel C-4326). 25 sq ft cartridge for smaller spas and skimmer baskets.

A clean, correctly sized cartridge keeps water moving through the heater and jets. Most hot tub flow errors (FLO, FL1, dr, HFL) and many no-heat calls start with a clogged filter. Match the length, diameter and end caps (open hole, threaded or handle) against your old cartridge before you order; the cross-reference numbers below are the quickest way to confirm.
