Oase FiltoClear Filter Foam

This replacement set is specifically engineered for the OASE FiltoClear 5200 (item number 91670). Please verify your filter's model number on the unit's label before purchasing to ensure a proper fit.

While you should rinse your foam regularly to remove debris, you typically need to replace the foam media once it loses its structural integrity or no longer springs back to its original shape after cleaning. Depending on your pond's biological load, this is usually necessary once per season or every 12 months.

You can absolutely rinse and reuse these foams several times throughout the season to maintain flow. However, over time, the foam cells will degrade and trap fine particles that rinsing cannot remove, which is when you should swap them out for a fresh set.

Yes, this is a complete replacement set designed to refresh your entire filtration media stack. It provides the exact components required to restore your FiltoClear 5200 to its original mechanical filtration capacity.

Using genuine OASE replacement parts ensures the foam density and dimensions are exactly calibrated for your specific filter canister. Generic alternatives often lack the correct pore size or fit, which can lead to water bypassing the filter media or clogging the system prematurely.
