Poolzilla Spa Filter Cartridge 2-Pack 14 7/8" x 6 5/8" Replacement for Unicel/Filbur/Jacuzzi — High-Flow Pleated Media

Poolzilla 2-pack replacement spa filter cartridges (14 7/8" L x 6 5/8" OD) deliver dependable filtration for compatible Unicel, Filbur and Jacuzzi spa models.

This two-filter set is built as a direct-fit replacement for common spa cartridges—including PLF6CH-960, Unicel 6CH-960, Filbur FC-2800 and equivalent Jacuzzi J-300/J-400 parts—so you can restore circulation and clarity without guessing on size or fit. The cartridges use a pleated, high-flow media engineered to trap hair, sediment and fine particles while maintaining the flow rate your spa system needs. Each filter is independently tested for dimension accuracy and pleat integrity to ensure consistent performance right out of the box.

How do these replacement filters fit my spa and which part numbers match?

• Direct dimensional match: 14 7/8" L x 6 5/8" OD, top handle, 2" bottom opening.
• Reference-compatible with PLF6CH-960, Unicel 6CH-960, Filbur FC-2800.
• Also cross-references PJW60TL-F2S, SD-00640, 6541-383, 6540-476 and Jacuzzi J-300/J-400.
• Poolzilla is an independent replacement brand; manufacturer names are for identification only.

What filtration performance can I expect from the Poolzilla cartridges?

The pleated media captures visible and fine debris to improve water clarity and protect your pump and heater from clogging. Because of a dense pleat count and a design aimed at maximizing surface area, these cartridges hold more dirt between cleanings than older round-fabric filters.

• Effective removal of hair, leaves, dust, sand, silt and visible particles.
• Maintains flow rates to help the circulation system run efficiently.
• Designed for easy rinsing—simply remove and spray with a hose for weekly maintenance.
• Can reduce visible turbidity and particulate-related taste/odor issues when used properly.

How long will each filter last and how should I maintain them?

Service life depends on bather load, surrounding debris and chemical balance, but typical replacement intervals fall between 1–2 years with normal home use. Regular rinsing and periodic deep cleaning will extend lifespan and keep pressure in the filter housing within ideal ranges.

• Weekly rinse to remove surface debris; deep-soak or filter cleaner every 2–3 months as needed.
• Replace when pleats show heavy discoloration, tears, or when flow and pressure don’t recover after cleaning.
• Keep water chemistry balanced to reduce scale and chemical wear on the media.

Are these cartridges easy to install and backed by support?

Yes—installation follows the same steps as the original cartridge: turn off power, open the filter housing, lift out the old cartridge and insert the Poolzilla unit by aligning the top and bottom openings. Poolzilla provides customer and technical support from New Jersey if you need assistance identifying the correct fit or troubleshooting post-installation issues.

• Simple drop-in installation with matching top handle and bottom opening dimensions.
• Packaged as a 2-pack so you have an immediate spare on hand.
• Customer service and technical support available for fit or performance questions.
