325 sq ft” refers to the total pleated surface area of the filter cartridges inside the tank. More surface area means the filter can trap more contaminants before cleaning is needed, resulting in longer filter cycles and reduced maintenance compared to smaller cartridge filters.
Clean the cartridges when the pressure gauge rises above normal operating levels (generally about 8-10 PSI above the clean baseline) or when flow slows. For many pool owners, that means rinsing every 2-6 weeks during peak season, depending on debris and pool use.
The Hayward 325 sq ft SwimClear cartridge filter uses specific large cartridge elements designed for this series. Compatible replacement cartridges include: Hayward OEM replacement cartridge(s) - typically CX3250 series Unicel compatible replacement - C‑7494
Pressure rises on the gauge that doesn’t drop after rinsing Reduced water flow or weak return jets Visible debris that won’t rinse out of the pleats If rinsing no longer restores performance, it may be time to install fresh cartridges.
