Abstract (en)
[origin: EP1077074A2] The nose filter consists of two filter housings(1,2) joined by a semicircular bridge piece (9). The top opening of the filter housing is preferably oval in shape and has an inwardly pointing rim holding a filter disc. The interior of the filter housing is smooth-surfaced and has a micro-roughened surface (5) on its outer part. The top end of the filter housing has lammelar incisions (10) in a lengthwise direction in relation to the axis of symmetry of the filter housing.
