Cryspool 08008 75 sq ft Spa Filter Cartridge - Reliable Replacement

Our review of the Cryspool 08008 spa filter cartridge finds it best for hot tub owners who need a practical, easy-to-clean replacement that matches common 75 sq. ft. cartridges. The bottom line: this filter delivers comparable water flow and fit to retail-brand replacements while using a durable trilobal fiber material that promotes deeper filtration and a longer service life. For anyone maintaining a Maax Spa or another compatible 75 sq. ft. model, this cartridge is a straightforward swap that balances performance and value.

Key Features

• 75 sq. ft. filtration area: Provides ample surface for trapping debris so hot tub water stays clearer between cleanings.
• Trilobal fiber material: Advanced fabric structure increases dirt-holding capacity and extends service life compared with standard point-bond fabric.
• Improved pleat structure: Enables deep penetration of impurities so the filter rinses clean and performance is restored after washing.
• Standard dimensions: At 13 in length and 8 in outside diameter, it fits a wide range of 75 sq. ft. spa models for easy replacement.
• Top and bottom fittings: A 2-1/16 in open top and 2 in male slip bottom make installation straightforward in compatible tubs.

Who It's For

This cartridge is ideal for owners of Maax Spas and other hot tubs that accept a 75 sq. ft. filter, who want a cost-effective, reliable replacement that performs like store-brand equivalents. It suits those who clean filters regularly and value a material that rinses back to near-new condition.

It is less suitable for tubs that require non-standard lengths or diameters, or for owners seeking specialty media such as chemical-specific cartridges. If a different connection type or unusual size is required, buyers should verify measurements before purchasing.
