An electrostatic air cleaner is highly efficient for air clearing, which allows blocking dust, tiny particles and bacteria. However, the cost of such devices is quite high; for example, the increase of the degree of cleaning by 6 % raises the relative value almost 3 times. As a result, it restrains their distribution in agriculture. The solution to this problem is possible by upgrading the design of the electrostatic air cleaner, which consists in science-based choosing the area of the collecting electrode. The standard research methods were used for the experiment: the method of multifactorial experiment, statistical analysis, determination of the adequacy of the experimental data. Several collection electrodes have been studied in the form of tubes with different inner surface, so that their area corresponds to the analytical values: smooth surface, corrugated surface, undulated surface, complex surface with interleaving niches and crowns (like cuts in firearms). As a result of the experimental studies the dependence of the degree of cleaning of the electrostatic air cleaner η on the speed of the particle movement to the collecting electrode ν and supply air w at a constant square area of the collecting electrode is found. The maximum degree of air cleaning from bacterial pathogens varies from 60 to 99 %. The use of air cleaning installations in conjunction with recirculation allows reducing the gas content in the room, where animals are kept, for 6 times; the number of pathogenic bacteria (coliform bacillus, staphylococcus) is reduced 10 times; the amount of the consumed electric power to maintain the microclimate is reduced 2 times; the young stock loss is decreased from 40 % to 5 %.
