Frequently Asked Questions
How does the FullFloXF C620 compare to the Pentair Clean and Clear Plus 520 sq ft?
Both are four-cartridge Pentair filters, but the FullFloXF C620 is the next-generation design — 100 sq ft more filter area (620 vs. 520 sq ft) and up to 25% more energy efficient due to FullFloXF's optimized flow design. Choose the C620 for maximum capacity and the latest Pentair filter technology.
How often do the cartridges need cleaning?
Clean when the pressure gauge reads 8–10 PSI above the clean starting pressure. With 620 sq ft of area, the C620 extends cleaning intervals compared to smaller filters. Remove the four cartridges and rinse each with a garden hose.
Does this filter require backwashing?
No. The FullFloXF is a cartridge filter — no backwash cycle. Remove and rinse the cartridges to clean. This saves water and preserves your pool's chemical balance compared to sand or D.E. backwashing.
