130 sqft 7" Diameter Filter Cartridge
Product Overview
The standard specification for Pentair Clean & Clear Plus 520 systems requiring precise fit and high-capacity filtration.
Pool techs across DFW stock Filbur cartridges because they maintain structural integrity under high pressure better than generic alternatives. This 130 sqft genuine OEM replacement is designed specifically for the Pentair Clean & Clear Plus 520 sq ft filter housing, ensuring the 7-inch diameter fits perfectly within the manifold. In our experience, Filbur's reinforced end caps and sharp pleat folds provide more effective surface area for trapping fine particulates compared to budget-tier imports.
Benefits & What Makes It Different

130 Sq Ft Filtration Media

Reinforced End Caps
Constructed to resist cracking and chemical degradation, maintaining the cartridge's shape throughout its service life.

When To Use This
Pro Tip
When cleaning these, avoid using a high-pressure power washer as it can tear the fibers; instead, use a specialized cartridge cleaning tool or a garden hose with a spray nozzle at a 45-degree angle.
Common Questions & Instructions
How often should I replace the 130 sqft Filbur cartridges in my Pentair 520 filter?
For a typical residential pool, these cartridges should be replaced every 12 to 24 months. You should swap them sooner if the baseline pressure gauge reading remains 8-10 PSI above the 'clean' starting point even after a thorough cleaning.
How many of these 130 sqft cartridges do I need for my filter housing?
The Pentair Clean & Clear Plus 520 is a multi-cartridge system that requires a full set of four 130 sqft cartridges to reach its rated 520 sq ft capacity. Replacing only one at a time can lead to uneven flow and premature wear on the new element.
What are the signs that my filter cartridge needs to be replaced rather than cleaned?
Look for visible signs like frayed fabric, broken bands, or cracked end caps. If your pool water remains cloudy despite balanced chemistry and long run times, the media may be 'blinded' by oils and minerals that cleaning can no longer remove.
