Abstract

It is presented a dust cup housing (11) comprising a filter assembly which comprises an outer filter (25) and an inner filter (24). The outer filter and inner filter are formed as receptacles and the inner filter is slidably insertable into the outer filter. In a mounted position the inner filter is arranged to be substantially fully inserted into the outer filter. The filter assembly further comprises a fixing member (40, 41; 50, 51; 60, 61) which is arranged to retain the inner filter in a predetermined displacement (d) position relative to the mounted position, in response to the inner filter being subjected to an extraction force for detaching the filter assembly from the dust cup housing. Thereby a user of the filter is in a convenient and intuitive way alerted that the filter assembly comprises more than one filter.
