This impeller is specifically designed to be compatible with Eheim Professionel 3 350 (2073), Eheim Professionel 3 600 (2075), Eheim Professionel 4+ 350 (2273) and Eheim Professionel 4+ 600 (2275) filters. Before making a purchase, please check your filter model to ensure compatibility. Using this impeller with an incompatible model may result in reduced performance or damage to your filter.

The frequency of impeller replacement depends on several factors, including the biological load of your aquarium and the hardness of the water. In general, it is recommended to check the condition of the impeller every 6 to 12 months. If you notice a decrease in water flow, abnormal noise from the filter, or signs of wear on the impeller itself, it is time to replace it. Regular replacement ensures optimal filter performance and a healthy environment for your fish.

Installing the replacement impeller is relatively simple. First, unplug your filter and remove it from the aquarium. Open the filter and locate the used impeller. Carefully remove the old impeller and replace it with the new one. Make sure the impeller is correctly positioned and rotates freely. Close the filter, plug it back in, and check that it is working properly. If you encounter any difficulties, consult your filter's user manual or contact a professional.
