\udThe present catalytic air purification device–air cleaning device is capable to reduce nitrogen oxide sand carbon monoxide concentrations in polluted air stream and to achieve high cleaning efficiency. The principle of operation of catalytic air cleaning device is based on plasma coating formed catalysts usage. At high temperatures and oxygen concentrations in the experimental device channel, catalysts become active and reactions of conversion of pollutants start. In this research, the efficiency of cleaning the air from nitrogen oxides and carbon monoxide, by using plasma coating formed titanium oxide and copper-chromium catalysts, is carried out. 50% propane – 50% butane gas mix was used to generate polluted air flow. The maximum cleaning efficiency, cleaning the air of nitrogen oxides and carbon monoxide, reached 86% and 77%, when the average flow rate of polluted air was 0.10 m/s, oxygen concentration in II section of device was 0.5–0.6% and in I section – 0.1–0.2%
