Cartridge filters for above-ground pools

• Pressure which remains high After rinse + soak.
• Crushed/opened folds, seam coming undone,unraveling media.
• Insufficient flow rate Despite pump being OK and basket clean. → Replacement.

Consult our comprehensive guide to select the optimal model based on your pool size, water flow rate, and desired filtration capacity.

Rinsing to the casing by opening the folds every 2–4 weeks(more often if pollen/high usage).

Degreasing soak(filter product)every 8-12 weeks or from persistent loss of flow/high pressure.

Air purge each time it is put back into service.

• Clarity: filter cartridge finer (~5–10 microns) than sand (~20–40 microns).
• Pressure drop: cartridge ≈ low (good for variable speed pumps).
• Costs/maintenance: sand = backwash (water rejected) but little handling; cartridge = no water lost, but regular rinsing/soaking.
• Quick choice: If you wantsimplicity and robustness→ sand;ultra-clear water and water saving→ cartridge.
