Why Replace All Four Cartridges Together?
Replacing the complete cartridge set at the same time helps provide:
- Balanced flow through all four elements
- More even debris loading
- Consistent filter pressure
- Better filtration performance
- Similar cartridge service life
- Easier future maintenance
Mixing heavily used elements with brand-new cartridges can lead to uneven resistance and filtration performance.

- Heavy-duty filtration media
- Molded end caps

Filbur states its quad-pack cartridges are produced to strict OEM specifications and are packaged as complete four-cartridge sets.
Maintenance Tips
For maximum cartridge life:
