Abstract
The present invention relates to a method for cleaning of a gaseous fluid from particles being present in the fluid, the gaseous fluid being ionized, i.e. the particles are subjected to a charging, and that the ionized gaseous fluid is brought to pass through a precipitator unit (2) including a filter medium. The invention also relates to a device for cleaning of a gaseous fluid. Filters for cleaning of air often require expensive filter medium and complicated arrangements as regards ionization of the air and charging of the filter medium. The present invention is characterized by an extremely simple method where the air is ionized and then the ionized air is brought to pass through a filter medium of polypropylene.
