HYGIENIC ASSESSMENT OF INDOOR AIR VENTILATION AND VENTILATION SYSTEMS

This article examines indoor air ventilation and the hygienic assessment of ventilation systems in residential buildings, educational institutions, offices, and other enclosed spaces. Indoor air quality directly affects human health, work performance, concentration, and general well-being. The article analyses natural and mechanical ventilation, air temperature, relative humidity, carbon dioxide concentration, particulate matter, and air exchange effectiveness. Drawing on recommendations from the World Health Organization and international ventilation standards, it explains the importance of ventilation for maintaining a healthy indoor environment. Particular attention is given to regular air quality monitoring, proper maintenance of ventilation equipment, and compliance with sanitary and hygienic requirements. Practical recommendations are provided for evaluating ventilation performance and improving indoor environmental conditions. The findings offer a conceptual basis for maintaining healthier and more comfortable indoor spaces.
