The biggest reason to buy is the American-made 100% Reemay filtration media, which is designed for durability and easier cleaning compared with generic pleated fabrics. Installation is simple and the cartridges fit models that use OEM R0554500 \/ C-7459 \/ PJAN85 cross-references, making this a practical swap for routine filter maintenance.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMade in USA:\u003c\/strong\u003e The cartridges use 100% Reemay filtration media manufactured in the United States, which supports consistency and controlled material quality.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupport bands:\u003c\/strong\u003e Each cartridge includes support bands around the element to help preserve pleat shape and reduce deformation during use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide compatibility:\u003c\/strong\u003e They are compatible with many OEM numbers including R0554500, C-7459, PJAN85 and FC-0800, simplifying replacements for several filter brands.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard dimensions:\u003c\/strong\u003e With a length of 27 in, outside diameter 7 in and inside diameter 3 in, the cartridges match the physical requirements of CL340 and CV340 housings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurability and cleanability:\u003c\/strong\u003e The Reemay media was selected specifically to withstand repeated cleaning and deliver sustained filtration performance over seasons.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThese cartridges work well for residential pool owners who run Jandy CL340, CV340 or other systems that accept the listed OEM cross-references and who want an aftermarket option made with resilient Reemay media.
