Optimal energy efficiency and silent operation: like the previous models, the EHEIM Professional 4 250 exterior filter is a real technical feat. The novelty lies in the "Xtender" function: when the filter masses are dirty and the water flow decreases, a button allows to adjust their adjustment if necessary.

This innovative technology makes it possible to delay by a few days the cleaning interval of the filter masses when it is dirty, without even damaging biological filtration.
