80 sqft 7" Diameter Filter Cartridge
Product Overview
A proven choice for maintaining the high-flow filtration standards of the Pentair Clean & Clear Plus 320 system.
This 80 sq ft Filbur cartridge is the standard specification for the Pentair Clean & Clear Plus 320 filter housing, which utilizes a four-cartridge manifold. In our experience, Filbur's reinforced end caps and sharp pleat folds provide a more reliable fit and better debris capacity than generic alternatives, ensuring your 320 sq ft system maintains its rated flow rate and water clarity.
Benefits & What Makes It Different
Precision 7-inch Diameter
Ensures a tight seal within the Pentair Clean & Clear Plus 320 manifold to prevent bypass of unfiltered water back into the pool.
80 Square Feet of Media
Provides the exact surface area required for a balanced 320 sq ft total filtration capacity when used in the standard set of four.
Reinforced End Caps
Filbur uses high-impact materials that reliably handle the high-pressure conditions common in large residential pool systems without cracking.
Compatibility
- Pentair Clean & Clear Plus 320 Filter Housing
- Systems requiring a 7-inch diameter 80 sq ft cartridge
- Four-cartridge manifold configurations
When To Use This
Pro Tip
Always replace all four cartridges at the same time; mixing old and new cartridges causes uneven flow, which forces the new filters to work harder and fail prematurely.
Common Questions & Instructions
How many 80 sq ft cartridges do I need for a Pentair Clean & Clear Plus 320?
The Pentair Clean & Clear Plus 320 filter housing is designed to hold exactly four of these 80 sq ft cartridges, totaling the 320 sq ft of filtration area the tank is named for.
When should I replace my Filbur filter cartridges?
We recommend replacing the full set every 12 to 24 months, or sooner if you notice a 10 PSI rise over your clean starting pressure that cannot be resolved by cleaning the pleats.
What are the signs that my filter cartridge needs replacing right now?
Look for a permanent rise in tank pressure, reduced water flow at the returns, or visible tears in the fabric media which allow debris to pass through the filter housing.
