Abstract

The method makes visible dust picked up by a dust extractor (2). The latter (2) has a conveyer channel (13) in which the picked up dust particles are advanced in an air stream. The conveyed dust particles are irradiated by light in an at least partly transparent section of the conveyer channel (13) to make them visible. Preferably, the dust particles are concentrated before being illuminated. The flow of the dust particle may be slowed down before they are illuminated. The movement of the visible dust particles may be projected onto a projection wall.
