The Dust Eater is an installation that connects seemingly distant areas of industrial engineering and post-futurist art with pro-environmental artistic and educational practice. The installation consists in a change of a device used for air purification in industrial processes into a monumental piece of art. The Dust Eater  meets the futurist postulate of usefulness of art. The 4,7 meters tall installation, maintaining the functional character of the device on which it is based, is intended to purify the urban air by absorbing the smog.The operation of the huge gas mask-like sculpture-machine is largely metaphorical,but it has a real capacity to filter PM 10 and PM 2,5 particles, i.e. benzopyrene and derivative fractions, which are responsible for the harmful effect of the city smog. This is possible thanks to the use of an advanced industrial HEPA filter. The Dust Eater  is also a specific station for monitoring quality of an urban air as results of its work are presented on the project website .On the metaphorical level, the operation of the Dust Eater  bears resemblance
to a purification ritual. In reference to the views held by futurists of the twentieth century,according to whom art together with new technologies should strive to solve the problems of the modern world, Bąkowski’s installation undertakes the
avant-garde postulate of the usefulness of art. It is a new formula of purism, a functional structureand a monumental ready-made at the same time. By the same token, it is an embodiment of the Praesentismus conception of Raoul Hausmann, who in the 1920s pointed to the equivalence of the museum and the factory, the sculpture and the industrial machine. The idea of placing the Dust Eater in the urban environment transfers the practice of industrial creation of a piece of art into the activist areas of ecology and pro-environmental, educational activities.
