KeePure Jandy CV340 Pool Filter Cartridge — 4×85 Sq Ft, 4 Pack, Compatible with Jandy CL340 and More

Meet the KeePure Jandy CV340 pool filter cartridge, a reliable, high-capacity replacement that fits a broad range of filter systems. This 4×85 sq ft cartridge is sold as a 4-pack, giving you ready replacements for the season and beyond. Key specifications include a length of 27 inches, an outside diameter of 7 inches, and top/bottom openings of 3 inches, designed for straightforward swaps in compatible units.

Wide compatibility with a practical approach

This cartridge is described as a compatible part, not an OEM replacement. It works with Jandy CL340 and CV340 units and also pairs with several third-party models such as Unicel C-7459, R0554500, PJAN85, Filbur FC-0800, A0557900, Aladdin 18504, and APCC7352. KeePure positions itself as an independent brand, offering a cost-conscious option without relying on a single manufacturer’s naming convention.

Filtration technology you can feel

Engineered with trilobal fabric technology, the cartridge is designed to capture a wide range of impurities — from fine dust to hair and leaves — helping water feel purer and look clearer. The fabric’s design aims for high dirt-holding capacity, which can reduce the frequency of backwashing and related water loss while sustaining steady flow.

Real-world use and maintenance made simple

In everyday use, the substantial filtration area of 4×85 sq ft supports efficient debris collection, which can be especially helpful for mid- to large-size pools or high-traffic weekends. The 3-inch top and bottom openings support a smooth installation with compatible equipment, helping you swap cartridges with minimal downtime.

• Scrub the fabric with a cartridge cleaner every 2–3 weeks to lift trapped debris.
• Rinse thoroughly with a garden hose to restore flow and extend cartridge life.

What you get and why it matters

• Four 27-inch cartridges with a 7-inch diameter provide ready replacements for ongoing maintenance.
• Large filtration area (4×85 sq ft) supports clearer water in bigger pools or high-use settings.
• Independent KeePure support and a six-month return window add peace of mind to your purchase.

Note: while this is a compatible part, KeePure remains an independent brand with a focus on reliable customer support. Use as part of a regular maintenance routine to help keep your pool water inviting across seasons.
