Cryspool replacement spa filter cartridge 23-5/8" (C-4995/FC-2940) trilobal fiber, 95 sq ft

If your spa or hot tub is running cloudy or the original cartridge has reached its service limit, the Cryspool 04087 provides a direct-fit replacement sized and shaped to match common OEM C-4995/FC-2940 cartridges. Built with trilobal fiber pleats and reinforced end caps, this cartridge is engineered to increase dirt-holding capacity and simplify routine cleaning so your water stays clearer between maintenance cycles.

How does the Cryspool 04087 improve spa water clarity?

The cartridge uses advanced trilobal fiber material that creates more surface area per pleat than standard point-bond media. That means the filter traps finer particles deeper in the pleat structure without restricting flow, helping pumps run efficiently while removing more contaminants.

• 95 square feet of filtration area for increased dirt-holding capacity
• Trilobal fiber media captures smaller particles and distributes debris throughout pleats
• Improved flow performance keeps circulation steady and reduces strain on the pump

Will this filter fit my spa model that lists C-4995 or FC-2940?

The Cryspool 04087 is manufactured to match the critical dimensions of common C-4995/FC-2940 style cartridges, including overall length and top and bottom openings. Always compare measurements to your existing cartridge to confirm fit before installation.

• Length: 23-5/8" to match OEM cartridges
• Outer diameter: 4-15/16" with 2-1/8" top and bottom openings
• Compatible alternatives: PCAL100 and 817-1000 references for cross-checking

How should I clean and maintain this replacement cartridge?

The Cryspool 04087 is designed for repeated cleaning thanks to its durable trilobal fabric and sturdy end caps. Rinse the pleats with a high-pressure hose and use a filter cleaning solution periodically; cleaning restores filtration depth and can extend the cartridge’s usable life.

• Rinse when pressure gauge indicates cleaning is needed
• Use a filter cleaner soak periodically for oil and scale removal
• Inspect end caps and pleats for damage; replace if torn or deformed

What are the core construction features and why do they matter?

The cartridge combines trilobal fiber media, reinforced pleats, and robust end caps to balance filtration efficiency with mechanical durability. These design choices reduce the frequency of replacements and help the filter maintain consistent performance through multiple cleanings.

• Trilobal fibers increase effective filtration area and longevity
• Reinforced pleat structure prevents collapse under flow pressure
• Durable end caps ensure a secure seal in the filter housing
