Cryspool 05039 Spa Filter – 35 Sq Ft Cartridge, 2 Pack, Marquis & Cal Spas Compatible

Overview

The Cryspool 05039 filter is a durable spa cartridge designed to fit a broad range of Marquis and Cal Spas systems. With a 12-1/2 inch length and a 5-3/16 inch outer diameter, this filter is built to sit securely in place while providing consistent performance. The bar-style top handle offers a comfortable grip for installation and removal, and the 2 inch MPT bottom connection helps ensure a reliable seal in your spa setup.

Using a 35 square foot filtration area, this cartridge is shaped to maximize surface area and promote thorough water contact with circulating pumps. The result is a cleaner feel to the water, with fewer visible particulates after a typical spa cycle. The 2 pack option gives you an extra filter on hand for quick swaps, helping you maintain clean water between cleanings.

Key Benefits and What It Means for Your Spa

• Size and fit that align with common Marquis and Cal Spas models, reducing guesswork during replacement.
• 35 sq ft filtration area for enhanced surface exposure and efficient particle removal.
• Advanced trilobal fiber material signifies higher capacity and longer life compared with standard point-bond fabrics.
• Easy cleaning design allows the pleats to be refreshed, helping the filter return toward near-new performance after washing.
• Solid end caps and pleats contribute to stable positioning and robust filtration under regular use.
• Regular cleaning can extend service life and minimize water usage by maintaining filtration efficiency.

Material and Construction

The filter uses a trilobal fiber material that supports deeper penetration of impurities into the pleats. This construction is paired with sturdy end caps and dependable pleats, which work together to resist deformation and maintain a strong seal over time.

Fit, Installation, and Maintenance

The top bar handle simplifies removal and installation, while the bottom 2" MPT connection keeps the cartridge aligned with your spa’s plumbing. For maintenance, rinse or wash the filter when your spa’s pressure gauge reaches a predetermined value. After washing, the filter can be returned to service as a refreshed, near-original performer. Proper care can help you get the most out of your cartridge while keeping water usage to a minimum.
