Overview Give your pool the gold-standard filtration it deserves with the Poolzilla replacement cartridge for the Hayward C200S filter system. This generously sized cartridge measures 28-3/16 inches tall with a 10-1/8 inch outer diameter, designed to drop right into your existing Hayward Star-Clear Plus housing without any adapters or modifications. The deeply pleated polyester media offers an enormous dirt-trapping surface area, which translates to one of the best benefits a pool owner can ask for — fewer cleanings, longer intervals between cartridge changes, and noticeably clearer water. The 4-inch top opening promotes smooth, balanced flow through your pump system, while reinforced molded end caps create a leak-proof seal that prevents dirty water from sneaking past the filter. The result is crystal-clear water your family can dive into with confidence all summer long. For best results, plan to rinse your cartridge every four to six weeks during heavy swim season and replace it at least once a year — typically right before you open the pool for spring, or whenever your filter pressure gauge climbs 8–10 PSI above its clean starting point. A fresh cartridge protects your pump from unnecessary strain, helps your chlorine and other chemicals work more efficiently, and keeps your water safe and inviting for the whole family. Swapping it out is genuinely simple: power down the pump, release the air relief valve, open the housing, lift out the old cartridge, and seat the new Poolzilla filter in its place. Order yours today and head into swim season with the peace of mind that comes from clean, healthy, beautifully clear pool water.
