Abstract
Air pollution is a growing environmental problem worldwide. Compelling epidemiological evidence shows that people spend more than 80% of their time indoors, and extensive studies have shown that indoor air pollution has an equal or greater impact on health when compared. with the surrounding environment. This article determines that the level of indoor fine dust pollution with PM2.5 and PM10 is quite high and changes over the seasons. Winter has the highest concentration, specifically PM2.5 accounting for 54g/m3, PM10 accounting for 97g/m3. The model for treating indoor dust with negative ions initially showed positive results with an efficiency of 70-84.8% at a device height of 75cm. This is the basis for further detailed research on fine dust treatment with negative ions.
