FOIRCEADAL Hot Tub Filter Cartridge Replacement — 2-Pack 1 1/2" SAE Thread, 45 sq ft Pleated

FOIRCEADAL replacement cartridge filters compatible with Unicel 6CH-940 and Filbur FC-0359 provide reliable 45 sq. ft. filtration in an easy-to-install 1 1/2" SAE threaded design.

If your spa or hot tub uses Unicel 6CH-940, Filbur FC-0359, Pleatco PWW50P3, Waterway Plastics 817-0050 or any of the equivalent models listed, this two-pack from FOIRCEADAL is designed as a direct-fit, reusable replacement. Each cartridge measures approximately 8 1/4" long with a 6" outside diameter and a 1 1/2" SAE bottom thread for straightforward installation. Constructed from durable PET composite media and reinforced end caps, these cartridges balance fine particle capture with good flow to keep water clear between deep cleanings.

How do these filters clean spa water effectively?

The FOIRCEADAL cartridges use PET composite pleated media that offers about 45 square feet of surface area, enabling the filter to trap sediment, hair, and typical debris while allowing consistent water circulation. The pleated design increases dirt-holding capacity without overly restricting flow, which helps usual pump operations stay efficient.

• Captures particles down to roughly 50 microns for clearer water
• 45 sq. ft. media surface for extended dirt capacity
• Reinforced center support maintains structural shape under pressure

Will these cartridges fit my existing hot tub or pool filter housing?

These replacements are made to match the dimensions and threading of common cross-reference models so they slide into housings that accept Unicel 6CH-940 or listed equivalents. Confirm your current filter’s length, diameter, and bottom thread before buying to ensure a correct match.

• Length: 8 1/4"; Outside diameter: 6"
• Bottom connection: 1 1/2" SAE thread compatible with listed models
• Compatible references include Filbur FC-0359, Pleatco PWW50P3, Waterway 817-0050, and more

How do I maintain and clean these replacement cartridges?

Maintenance is simple: remove the cartridge, rinse with a garden hose, and allow it to dry before reinstalling when needed. The PET composite media is designed for repeated rinses; deep cleans can be performed with a filter cleaner soak if heavy oils or scaling accumulate.

• Routine rinse restores most filtering performance quickly
• Periodic soak with manufacturer-recommended cleaner for thorough maintenance
• Reusable design reduces frequency of full replacements and waste

What durability and support can I expect from FOIRCEADAL filters?

Built with reinforced end caps and a sturdy center core, these cartridges are engineered to retain shape and resist collapse under typical spa pump pressures. FOIRCEADAL also offers customer support to help with selection, installation, or troubleshooting when required.

• Robust construction for prolonged service life
• Manufacturer support available for fitment and installation questions
• Sold as a convenient 2-pack for immediate replacement and backup
