SEE REPLACEMENT PART: PH105

The Filbur FC-6110 C-7685 PH105-4 Spa/Pool Filter Cartridge is a replacement spa and pool filter cartridge from Filbur Manufacturing, selected for customers who need a clean, dependable cartridge for routine water filtration service. It is listed with the reference identifiers C-7685 PH105-4 to help match existing cartridges, filter labels, and cross-reference notes during replacement. This cartridge is a practical replacement option when the current filter is worn, stained, crushed, or no longer rinses clean after normal maintenance.

Use this cartridge as part of a regular filter maintenance schedule to support better water clarity, improved debris capture, and more consistent flow through the filtration system. Before ordering, compare the part number, length, outside diameter, inside diameter or opening size, end-cap style, and any printed cross-reference numbers on your existing cartridge. Proper fit is important for sealing, circulation, and overall filtration performance.

This item is best suited for pool and spa owners, service technicians, and maintenance teams replacing an existing cartridge with a matching Filbur model. Always clean the filter area before installation, seat the cartridge fully, and follow the equipment manufacturer's maintenance guidance for rinse intervals, chemical balance, and replacement timing.
