This is an original Miele spare parts. Unfortunately, this filter is missing (HA), the previously existing activated carbon layer. Let's see how that now affects odor standard. Hopefully not negative. Unfortunately, there are problems with the height, the left bracket does not engage, even with very heavy pressure. Perhaps thus the filter effect will be worse. Delivery by Amazon outstanding. Note 1! Addendum: After inserting the new filter SF-HA 50 (without activated carbon layer) smells the filtered exhaust our expensive S5 Ecoline parquet now no longer better than the exhaust of a cheap device with 1-Euro-filter bag.
