Overview Keep your pool water crystal clear all season with the Poolzilla replacement filter cartridge for the Pentair Clean & Clear 200. With a tall, generously pleated polyester filtration surface stretching 31.125 inches in length and 10.0625 inches in outer diameter, this cartridge gives your pool plenty of dirt-trapping real estate — which means longer stretches between cleanings, more reliable circulation, and noticeably clearer water. The 6-inch open-end core promotes balanced flow through every pleat, so water moves freely while fine debris, dust, leaves, and even microscopic particles get caught and held. Sturdy molded end caps create a tight, leak-proof seal inside your filter housing, so dirty water can't sneak around the cartridge and back into your pool. The result? A pump that runs easier, chemicals that work harder, and a backyard that's always ready for swim time. Plan to rinse your cartridge every four to six weeks and replace it once a year, or sooner if you notice your filter pressure gauge climbing 8–10 PSI above its normal reading, water turning cloudy after shocking, or your pump straining to keep up. A worn-out filter quietly forces your equipment to work harder, throws off your chemical balance, and shortens the life of your pump — so a fresh cartridge is one of the easiest, most affordable upgrades you can make. Installation takes about five minutes: power off the pump, open the housing, lift out the old cartridge, and drop the new Poolzilla filter right in. Order yours today and head into swim season with the confidence that your pool will be sparkling, safe, and ready for every cannonball.
