Overview Keep your pool gleaming all summer long with the Poolzilla replacement filter cartridge for the Hayward C150S — a heavy-duty pleated cartridge designed to deliver crystal-clear water with less maintenance. Standing 23⅛ inches tall with a 10⅛-inch outer diameter and a 4-inch top opening, this generously sized cartridge offers plenty of pleated polyester surface area to trap dirt, leaves, pollen, sunscreen residue, and other fine debris that can cloud your water. More surface area means your filter holds more dirt between cleanings, your pump works less, and you spend more time swimming and less time fussing with maintenance. Sturdy molded end caps create a leak-proof seal inside the filter housing, so every drop of water passes through the media — not around it — for the kind of brilliant clarity your family deserves. For the cleanest, healthiest pool water, plan to rinse this cartridge every four to six weeks and replace it at the start of each swim season — or sooner if your pump pressure climbs 8–10 PSI above its normal reading or your water looks cloudy even after balancing chemicals. A fresh cartridge doesn't just improve appearance; it reduces strain on your pump motor, cuts down on chemical use, and helps your entire pool system run more efficiently. Swapping it out takes about five minutes: power down the pump, release the air relief valve, open the housing, lift out the old filter, and seat the new Poolzilla cartridge in its place. Order yours today, keep a spare on the shelf, and head into swim season ready for nothing but blue skies and clear water.
