Cartridge filters for above-ground pools

• Pressurewhich remains highAfterrinse + soak.
• Crushed/opened folds, seam coming undone,unraveling media.
• Insufficient flow rateDespite 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.

Rinsingto the casing by opening the foldsevery 2–4 weeks(more often if pollen/high usage).

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

Air purgeeach 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.
