Pool Filter Cartridge for Filbur FC-1977 - Replaces Unicel C-7471, J-CQ420

Overview

Enjoy effortlessly clean pool water all season with the Poolzilla replacement filter cartridge (SKU 02-02-023), a high-capacity pleated cartridge built for serious filtration in residential pool systems. Measuring 26.75 inches tall with an outer diameter of 6.625 inches, this generously sized cartridge is engineered to drop right into standard tall-body filter housings without shimming, trimming, or guesswork. The deep accordion-style pleats dramatically increase the dirt-trapping surface, which means your filter captures more debris between cleanings and your pump doesn't have to work as hard to keep water moving. The result? Crystal-clear water, fewer maintenance interruptions, and more time actually enjoying your backyard.

For best results, plan to rinse your cartridge every four to six weeks and replace it at the start of each swim season, or sooner if your pump pressure gauge climbs 8–10 PSI above its normal reading or your water turns stubbornly cloudy. A fresh filter isn't just about clarity — it reduces strain on your pump motor, lowers your chemical usage, and keeps the water your family swims in genuinely clean. Swapping in a new cartridge takes about five minutes: power off the pump, open the filter housing, slide the old one out, and seat the new Poolzilla filter in its place. Order yours today (and grab a spare while you're at it) so you're ready the moment swim season kicks off — your pool, and your weekends, will thank you.
