Cryspool PAS28 Spa Filter Cartridge 7" x 6" Replacement with Trilobal Fiber Pleats for PAS28/PAS28-F2L

The Cryspool PAS28 is a 7-inch replacement spa filter cartridge built with trilobal fiber pleats to improve debris capture, durability, and cleanability for compatible spa and hot tub systems.

This replacement filter cartridge is engineered to match PAS28 and PAS28-F2L style housings while using an advanced trilobal fiber media to trap fine particles and resist rapid clogging. Its 7" length, 6" outer diameter, and standard 2" open top with 2" male thread MPT bottom make it a direct-fit swap in many common spa setups. Cryspool offers this as an independent brand alternative with robust end caps and pleat construction to help extend the usable life between replacements when cleaned properly.

Will this Cryspool PAS28 fit my spa or hot tub?

Check your existing cartridge dimensions and part references before ordering. The Cryspool PAS28 is made to the same nominal size and fitting spec as PAS28 family filters and several OEM part numbers, so it will fit if your current cartridge matches these measurements.

• Length: 7 inches; outer diameter: 6 inches
• Top opening: 2 inches (open)
• Bottom: 2" male thread (MPT)
• Compatible references: PAS28, PAS28-F2L-B12, X29-PAS28-F2L, FC-0309, FC-0312, 06-0052-12, 06-0055-12, 60204, SD-01330

How does the trilobal fiber media improve filtration?

The cartridge uses multilayer trilobal fibers instead of standard point-bond fabric, which increases surface area and creates deeper pleat channels for trapping particles. This design improves debris retention while keeping flow rate more consistent, so pumps experience less strain and the water clears faster during normal operation.

• Trilobal fiber increases particle-holding capacity
• Deeper pleats reduce rapid clogging and maintain flow
• Durable media resists breakdown under regular cleaning

What’s the best way to clean and maintain this filter?

The improved trilobal pleat structure is designed to release embedded dirt during washing, restoring much of the cartridge’s filtering ability. Clean it routinely when your system’s pressure gauge reaches the recommended limit and allow the filter to dry fully before reinstalling to prolong life and performance.

• Rinse coarse debris with low-pressure water spray between pleats
• Soak with a non-foaming filter cleaner for deep oil and grease removal
• Inspect end caps and pleats for damage; replace if torn or misshapen

Why choose the Cryspool replacement over other cartridges?

Cryspool focuses on durable materials and quality construction to give a balance of filtration performance and cleanability at a competitive price. The combination of sturdy end caps, consistent pleat spacing, and trilobal fiber media provides reliable operation and extended service life when maintained correctly.

• Independent-brand alternative for common PAS28 references
• Robust pleats and end caps for long-term use
• Easy to clean structure reduces replacement frequency

Who is this for: The Cryspool PAS28 replacement cartridge is ideal for spa and hot tub owners who need a direct-fit, cost-effective filter that balances fine filtration with good cleanability. It suits DIY maintainers and service technicians replacing PAS28-style cartridges, especially where regular cleaning is part of the maintenance plan and a durable, longer-lasting media is preferred over disposable alternatives.
