Subways, as the places where a large number of people are present, are put under under stringent standards of high microlimate and air quality, namely, the content of air-borne dust. In order to maintain dust concentration within the permissible limits, it is suggested to install air filters at ventilation connections at subway stations, which are affected by the piston effect. Using the earlier experimental results, the nonstationary air flow parameters under the piston effect and the structure of air flow at the ventilation connections at subway stations are determined in two-dimensional layout, which allows selection of filtration equipment for removal of dust from subway air, and enables determination of the equipment location at ventilation connections. In order to validate the filtration equipment selection, the review and analysis of the geometry, design and performance of the available facilities are carried out. The most suitable filtration equipment for air dedusting is suggested.
