Since most of the people spend 80 – 90%of their time indoors, it is important to understand the mechanism of transport of pollutants between the interior and exterior of a building. It is expected that effective ventilation of the building interior will allow maintaining good air quality in the room, among others by limiting the concentration of carbon dioxide, air humidity, chemical pollution, etc.At the same time, during periods of very high PM concentration in the atmosphere, intentional air exchange causes an increase in dust concentration inside the room. The article analyzed the impact of external conditions on the quality of indoor air in two educational rooms with a gravity ventilation system. Statistical analysis of the obtained readings allowed us to determine the time delay after which we can expect an increase in internal concentrations. This conclusion may be an indication of how rooms should be used during periods of increased levels of suspended dust concentrations.
