KEEPURE Jandy CV340 Replacement Pool Filter Cartridges 4-Pack (4×85 sq ft) Trilobal Fabric, 27"×7"

KEEPURE's Jandy CV340-compatible cartridge is a drop-in replacement filter pack (4 cartridges, 85 sq.ft. each) built to restore clear, debris-free pool water for Jandy CL340/CV340-style systems.

These four replacement cartridges are designed to fit Jandy CV340 and many cross-reference models so you can avoid buying an expensive OEM part while keeping filtration performance high. Each cartridge measures 27" long with a 7" outside diameter and 3" top/bottom openings. The media uses trilobal fabric for finer particle capture and larger dirt-holding capacity versus older pleat materials, and the set is sized to match the original 85 sq.ft. cartridge area used by common Jandy/Unicel/Filbur models.

Will these cartridges fit my Jandy CL340 or equivalent filter?

Yes — these KEEPURE cartridges were manufactured to match dimensions and connections of Jandy CL340/CV340 and several compatible replacement part numbers. They are sold as compatible, not OEM, so check measurements and model cross-references before ordering.

• Length: 27"; outside diameter: 7"; top/bottom openings: 3"
• Compatible with: Jandy CL340, CV340, PJAN85, Unicel C-7459, R0554500
• Also fits common cross-references: Filbur FC-0800, A0557900, Aladdin 18504

How does the trilobal fabric improve pool water quality?

Trilobal filter fabric features a special fiber shape that increases surface area and creates fine channels to trap smaller particles. The result is improved removal of hair, sand, pollen and fine sediment while extending the intervals between cleanings compared to plain polyester media.

• Higher particle capture for finer debris
• Greater dirt-holding capacity per cartridge
• Maintains flow rates while filtering smaller contaminants

How do I clean and maintain these cartridges to extend life?

Maintenance is simple: rinse and scrub every 2–3 weeks under normal pool loads, and more often during heavy use or leaf season. Deep-cleaning with a cartridge cleaner every few months removes oils and mineral buildup and helps the fabric retain filtration performance.

• Quick maintenance: spray with a garden hose and scrub pleats
• Deep clean: soak in a cartridge cleaner solution for stubborn oils/minerals
• Inspect pleats and end caps for damage when cleaning

What warranty and support does KEEPURE provide?

KEEPURE offers a six-month return policy for quality-related issues and dedicated support to help with fitment or performance questions. The product is marketed as a compatible aftermarket cartridge; original manufacturer names are provided for reference only.

• 6-month return policy for quality concerns
• Customer support available for part compatibility assistance

Who is this for: Pool owners or service professionals who need a cost-effective, high-capacity replacement for Jandy CL340/CV340-style cartridges. Ideal for backyard pools that require reliable particle removal without paying OEM prices, these KEEPURE cartridges suit weekly maintenance schedules and heavier bather or foliage loads when longer dirt-holding capacity is desired.
