The issue of indoor air quality is becoming increasingly important. Ensuring optimal air parameters is important for the health of people who are particularly sensitive to impurities contained therein. Finding solutions that improve the quality of indoor air requires a prior detailed recognition of the problem of its pollution. The subject of the research is dust pollution in the air in a teaching laboratory room. The attention was focused on the characteristics of air pollution with the total dust fraction and suspended particulate fractions PM10 and PM2.5. The dust content was measured with a laser meter enabling indirect measurement. It consists in using the phenomenon of damping laser light scattered on the tested air sample at an angle of 90 degrees. As a result of the conducted research, factors influencing the increase of dust concentration in the indoor air were identified. These include the quality of the outdoor air and the source of dust emission in the room. In order to obtain more comprehensive data, it is necessary to continue the research with the possibility of extending the duration of the measurement tests and the test cycle.
