The lifespan of the Air Manager E10 Filter is about 1500 hours. The UltiMaker S5 not only tracks the usage-time, but it can also detect if a filter is present. The 3 filter stages include Peak Performance, Replacement Near, and Replacement Advised. Use the filter replacement wizard found in the maintenance section of the printer to learn how to replace the filter, which will reset the filter lifetime counter back to zero.
