Overview Keep your pool water beautifully clear with the Poolzilla replacement filter cartridge built for the Jandy CS 250 system — a workhorse cartridge designed for serious residential pools that demand reliable, efficient filtration. Standing 33.125 inches tall with an 8.9375-inch outer diameter and a 4-inch top opening, this cartridge is precision-sized to drop right into your CS 250 housing with zero modifications, zero shimming, and zero guesswork. The deep, accordion-style pleats dramatically increase the dirt-trapping surface area, which means your filter captures more debris between cleanings and your pump doesn't have to strain against a clogged element. Rigid molded end caps create a leak-proof seal so every drop of water passes through the filter media — not around it — giving you the crystal-clear water your family deserves all swim season long. Plan to rinse your CS 250 cartridge every four to six weeks during heavy swim season and replace it once a year — or sooner if you notice your filter pressure gauge climbing 8–10 PSI above its clean baseline, water clarity starting to fade, or your chemicals working harder than usual to keep things balanced. A fresh cartridge takes the load off your pump motor, helps your sanitizer do its job, and keeps your pool looking inviting for every pool party and lazy afternoon swim. Installation is genuinely easy: shut off the pump, open the filter tank, lift out the old cartridge, drop the new Poolzilla element in, and you're back in business in about ten minutes. Order yours today — and grab a spare while you're at it — so you're fully stocked and swim-ready when the temperature climbs. What's Included Your order includes the selected quantity of replacement pool filter cartridges. Each unit is individually inspected for quality before shipping.
