About this spa filter cartridge

Clarathon FC-2972 Spa Filter PLBS100 C-5397. Cross-references Unicel C-5397 / PLBS100. Match length, diameter and end caps to your old filter.

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.
