Overview Keep your Pentair Clean & Clear Plus running like new with the Poolzilla PCC105 replacement filter cartridge — a tall, high-capacity pleated cartridge engineered to bring crystal-clear water back to your backyard. At 26 inches long and 7 inches in outer diameter with a 3-inch open top, this cartridge is sized to drop straight into Pentair Clean & Clear Plus 420 and 520 multi-cartridge housings (pre-1998 models) with no shimming, trimming, or guesswork. The deep, accordion-style pleats deliver an enormous dirt-trapping surface — meaning your filter captures more debris between cleanings, your pump doesn't have to push as hard, and you spend more weekends actually swimming instead of fussing with maintenance. Rigid molded end caps lock the pleats firmly in place to prevent bypass, so every gallon flowing through your system gets properly filtered for that glassy, sparkling water your family loves. Because Clean & Clear Plus systems use multiple cartridges working together, plan to replace all of them at the same time — typically every one to two years, or sooner if you notice your pressure gauge climbing 8–10 PSI above its clean baseline, your water turning cloudy, or your chemicals struggling to hold their balance. Fresh cartridges reduce strain on your pump motor, cut down on chemical use, and ensure the water your family swims in is genuinely clean from the first cannonball of the season to the last pool party of the year. Rinse the pleats every four to six weeks during heavy use to extend their life, and keep a fresh set of Poolzilla PCC105 cartridges on the shelf so you're always ready. Order yours today and head into swim season with the peace of mind that comes from clean, clear, worry-free water.
