About this spa filter cartridge

Clarathon FC-3960 Spa Filter (Hot Spring / Watkins, replaces PWK65 / C-8465). 65 sq ft filter for Hot Spring and Watkins spas.

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.
