The Control of Air-Borne Bacteria and Fungus Spores By Means Of Aerosols

Abstract

IN a previous communication we (Pulvertaft, Lemon & Walker, 1939), gave an account of a method of sterilizing air by means of finely atomized antiseptic solutions, founded on the principles outlined by Trillat (1938). His claims were fully confirmed. The mists used in this method may be produced by a number of different appliances, and in the experiments here described were produced by the “Phantomyst” (Andre Components, Ltd.). The essential appliances are:(1) a mechanical compressor, electrically driven, and (2) an atomizer, usually of scent-spray type, provided with (3) a baffling system which returns to the reservoir droplets above a certain size, thus avoiding much wastage.
