115 SqFt Filter Cartridge 4 Pack
Product Overview
Pool techs reach for these Filbur cartridges when servicing CL460 and CV460 housings to ensure a precise fit and reliable debris capture.
These 115 SqFt genuine replacement cartridges are the standard specification for maintaining water clarity in large-capacity systems. In our experience, Filbur provides the material density required to handle fine particulates without the premature collapsing often seen in generic alternatives. This 4-pack is designed specifically for the CL460 and CV460 series, offering a total of 460 square feet of filtration surface area.
Benefits & What Makes It Different
Precision Fit for CL460/CV460
These cartridges are engineered to seat perfectly within the filter housing, preventing bypass of unfiltered water back into the pool.
115 SqFt Filtration Media
Each cartridge provides a high surface area to trap fine debris, oils, and organic matter before they return to the pool environment.
High-Density Core Support
The internal core is built to withstand the pressure of high-flow pumps without buckling or restricting water movement during operation.
Compatibility
- CL460 Filter Housings
- CV460 Filter Housings
When To Use This
Pro Tip
Always record your 'clean' pressure reading on the filter tank with a permanent marker; it makes it much easier to identify exactly when the 115 SqFt cartridges have reached their debris capacity.
Common Questions & Instructions
How do I know when it is time to swap out my CL460 filter cartridges?
You should monitor your pressure gauge; a rise of 8-10 PSI over the clean starting pressure, or a noticeable reduction in flow at the returns, indicates the cartridges are loaded and require replacement.
Where are these cartridges located and what do they actually trap?
These go inside your main filter housing (like the CV460) and act as the primary barrier for dirt, pollen, and microscopic debris that passes through the pump basket.
How many of these 4-packs should I keep on hand for a typical pool season?
Most homeowners find that one 4-pack per season is sufficient, though pools with heavy bather loads or high debris may require a second set to maintain optimal flow.
