Fits perfectly in my industry home sucker (Nilfisk 107 402 048 wet / dry vacuum Multi 20 T) and makes even a wertigeren impression as the original filter. The price of EUR 20 could be cheaper, but may well correspond to the market price for suction filter. The suction power has considerably increased, but this is not surprising, since the old filter from the suction of wet construction dust (which I avoid in future wants) was hard relocated.
