Students and teachers spend about 70% of the day in educational institutions. Therefore, recently in the world studies of the effect of air quality on human well-being and human performance have been conducted more often. The high content of suspended particles in the indoor air can lead to the development of allergies, and also serves as a factor of the transmission of respiratory viral infections. The purpose of this study was to determine the degree of dust in the indoor air in the classrooms. For this purpose, the photoelectric method of registration of aerosol particles and the Koch method were used. The results were evaluated according to two requirements for the amount of suspended particles in the air of the educational institution. Depending on the amount of suspended particles and their size, recommendations were given for filters to reduce the dust content of the internal air.
