AQUIVEX CL340 Pool Filter Cartridge Replacement for Jandy Pro Series — 27in 340 sq ft, 4-Pack, Trilobal Media

AQUIVEX CL340 is a high-capacity replacement pool filter cartridge engineered to fit Jandy Pro Series 340 systems and trap fine debris for clearer water.

This four-pack of AQUIVEX CL340 cartridges offers a direct-fit replacement for Jandy CL340/CV340 and equivalent aftermarket models, providing a cost-effective way to restore filtration performance. Each cartridge delivers 340 square feet of trilobal fabric filtration across a 27" length and robust end-cap construction for dependable service life. Designed for easy removal, rinsing, and deep cleaning, these cartridges help keep skimmers and pumps working efficiently by capturing hair, leaves, sediment, and other small particles.

How does the AQUIVEX CL340 improve filtration compared with older cartridges?

These cartridges use advanced trilobal fibers to increase dirt-holding capacity without sacrificing flow. The fabric captures particles down to roughly 10–15 microns while resisting compaction, which helps maintain steady water pressure and longer intervals between cleanings.

• 340 sq. ft. effective filtration area per cartridge for larger surface contact.
• Trilobal media holds more debris than standard point-bonded materials.
• Stable water flow reduces pressure spikes and pump strain.
• Captures fine particles such as dust, sand, and hair.

Will these cartridges fit my Jandy Pro Series 340 filter?

AQUIVEX CL340 units are manufactured to match the dimensions and connections of Jandy Pro Series 340 models, so they drop into the existing housing without modification. They are also cross-compatible with common aftermarket equivalents, making them a convenient replacement option.

• Dimensions: 27" length, 7" outside diameter, 3" top/bottom openings.
• Direct-fit for Jandy CL340 and CV340 housings.
• Compatible with Pleatco PJAN85 and Filbur/Unicel equivalents.
• Sold as a 4-pack to service multi-cartridge systems or keep spares on hand.

How do I clean and maintain these cartridges for long life?

Routine maintenance is simple: remove the cartridge, hose off loose debris, and periodically soak in a cleaning solution to dissolve oils and trapped fine particles. The solid-core end caps are built to resist cracking during handling and cleaning, so gentle care and proper storage extend usable life.

• Hose rinse after each season or heavy use to remove surface debris.
• Deep-clean with cartridge cleaner for stubborn oils and scales.
• Inspect end caps and pleats for damage; replace if torn or warped.
• Allow to dry fully before reinstalling to prevent odors or mildew.

What materials and construction features should I expect?

The AQUIVEX CL340 uses premium trilobal filter fabric wrapped around a reinforced core and sealed with break-resistant end caps. This combination preserves pleat shape under pressure and improves particle retention compared with lower-grade media.

• Premium trilobal fabric for higher dirt-holding and consistent flow.
• Solid-core support minimizes collapse and maintains pleat spacing.
• Durable end caps resist cracking during normal use and cleaning.
• Engineered to trap particles approximately 10–15 microns in size.
