PCT No. PCT/SE87/00183 Sec. 371 Date Sep. 26, 1988 Sec. 102(e) Date Sep. 26, 1988 PCT Filed Apr. 13, 1987 PCT Pub. No. WO87/06501 PCT Pub. Date Nov. 5, 1987.An arrangement for generating an electric corona discharge in air having a corona electrode, a target electrode which is spaced from the corona electrode, and a d.c. voltage source, the respective terminals of which are connected to the corona electrode and the target electrode. The voltage of the voltage source and the construction of the corona electrode are such as to generate a corona discharge at the corona electrode. A conduit is provided for continuously removing the air present in the immediate vicinity of the corona electrode and dealing with the air thus removed in a manner to render innocuous physiologically harmful substances or irritants present in the air and generated by the corona discharge, such as primarily ozone and nitrogen oxides.
