Cryspool Spa Filter Cartridge 04059 — 50 sq ft Trilobal Replacement for C-4405/PRB25SF, Pleated Durable End Caps

Cryspool 04059 is a 50 sq. ft. trilobal-fiber spa filter cartridge designed to replace C-4405 and PRB25SF-style filters for consistent, easy-to-maintain water filtration.

This replacement cartridge is built to fit a range of hot tub and spa models that use the C-4405/PRB25SF family of filters. It combines a multilayer trilobal fiber media, reinforced end caps and pleated construction to capture fine particles while remaining simple to rinse and reuse. The filter’s dimensions—6-5/8" length, 5" outer diameter and 2-1/8" open top and bottom—match common OEM sizes so it installs without modification.

How does the Cryspool 04059 improve spa water clarity?

The trilobal fiber media increases surface area and traps more microscopic debris than standard point-bond fabrics. That finer capture helps pumps and sanitizers work more efficiently, reducing visible particles and prolonging cleaner water between cleanings.

• 50 sq. ft. filtration area for higher dirt-holding capacity
• Trilobal fibers increase particulate capture versus basic media
• Pleated construction exposes more media to flow for consistent filtration

How should I care for and clean this Cryspool filter?

The filter’s improved trilobal structure allows trapped impurities to release more easily during rinsing, restoring much of the original performance. Clean the cartridge when your spa’s pressure gauge reaches the manufacturer-recommended level or on a regular schedule, and avoid harsh chemicals that can damage the media.

• Rinse with a garden hose, directing water between pleats for deep cleaning
• Use a filter-cleaning solution periodically for grease and oils
• Allow to dry fully before reinstalling to assess remaining debris visually
