Cartridge Style Filter 100 sq ft (SKU EC-188594) is built for demanding residential pool installations where clarity, capacity, and low-maintenance operation matter. With its 100 square-foot effective area and four large cartridge elements, the unit delivers the filtration performance of traditional D.E. systems—in a cartridge-style format that simplifies servicing. The durable tank construction and efficient internal flow path make the system well-suited for high turnover zones or larger in-ground pool setups. Maintenance is streamlined thanks to the removable cartridges and smart design. If you're upgrading to a premium filter that reduces service time without sacrificing clarity, this model is a strong choice.\u003c\/p\u003e\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003eTo maximize performance, ensure your pump and plumbing deliver flow at or below the ~160 GPM guideline rating. Confirm you have at least ~74″ vertical clearance above the unit for cartridge removal and lid access. When your pressure gauge climbs about ~10 psi above its clean-start reading, conduct maintenance—rinse cartridges or backwash as appropriate. Use genuine replacement cartridges and inspect the O-ring, clamp ring, and lid seal with each service cycle.\u003c\/p\u003e\n\u003ch3\u003eInstallation Tips\u003c\/h3\u003e\n\u003cp\u003eHigh-level safety\/compatibility notes only: Disconnect power to the pump and relieve system pressure before installation or servicing. Ensure the filter is mounted on a level, supported pad rated for the full weight of tank + water + cartridges. Confirm plumbing ports (2″ standard) match your system or use adapters as needed. Lubricate the O-ring and ensure the clamp ring or lid fasteners are correctly torqued. Use a compatible multiport or slide valve rated for the system flow (valve sold separately). Confirm the air-relief valve is functioning and the drain port is accessible before restarting the system.\u003c\/p\u003e","brand":"Cavanaugh Pool, Spa \u0026 Patio, Inc.","offers":[{"title":"Default Title","offer_id":62589890167155,"sku":"PAC-05-9594","price":2273.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0983\/2464\/4211\/files\/QuadDE-banner_ada18221-8880-452c-85ae-ef04129875ee.png?v=1772563788","url":"https:\/\/shop.cavanaughpool.com\/products\/pentair-quad-d-e-cartridge-style-filters-100-ec-188594","provider":"Cavanaugh Pool, Spa \u0026 Patio, Inc.","version":"1.0","type":"link"}
