ABSTRACT:
A compact unit adapted to remove particulate contaminants from the atmosphere of a room and at the same time to render the atmosphere more pleasing. The unit is provided with a casing that includes a cylindrical flow tube through which the air to be purified is drawn by means of a suction fan at the outlet end of the tube. Attachable to the inlet end of the tube is a series of inter-coupled filter rings which are progressively graded to remove more or less coarse particles. The last filter ring in the series is constituted by a porous disc impregnated with a volatile aromatic liquid which is volatilized by the forced air stream to impart a fragrance thereto. Intermediate the inlet and outlet of the tube is an electrostatic precipitator constituted by a negatively-charged ionizer electrode and a positively-charged tubular collector which act to extract residual fine particles from the air stream, whereby the air returned to the atmosphere from the outlet is substantially free of contaminants and is fragrant.
