Benefits

The Pentair FullFloXF 620 helps deliver clean, clear pool water while supporting high-flow circulation systems. Its 620 sq. ft. cartridge area gives the filter more surface area to capture dirt, debris, oils, and fine particles, which can help reduce how often the cartridges need to be cleaned.

Because this is a cartridge filter, it does not require backwashing. That means less water waste, easier maintenance, and a cleaner equipment pad setup compared to traditional sand or D.E. filters that require backwash plumbing.

The FullFloXF design is built for larger pools and statement pool systems where strong flow, efficient filtration, and extended cleaning intervals are important.
