Brus, nestled in the southwestern region of Serbia, occupies a unique geographic position within the Prolom Banja municipality. Situated at approximately 43.38° N, 21.03° E, the town’s elevation averages around 680 meters (2,231 feet) above sea level, placing it firmly within the mountainous terrain of the Kopaonik mountain range foothills. This elevated location significantly influences local air circulation patterns. The surrounding landscape is characterized by rolling hills, dense deciduous and coniferous forests, and agricultural fields, creating a distinct urban–rural gradient. To the north and east, the land gradually descends towards the Morava River valley, a historically important agricultural region. To the south and west, the terrain rises sharply towards the Kopaonik massif, a dominant feature impacting wind direction and potential for cold air pooling. Brus itself is a relatively small settlement, exhibiting a compact urban form with a mix of traditional Serbian architecture and more modern developments. While not directly adjacent to a major river, the proximity to smaller streams and groundwater sources contributes to local humidity. The region's historical reliance on agriculture, particularly fruit orchards and vineyards, means that seasonal burning practices, though regulated, can occasionally contribute to localized air pollution events. Furthermore, while Brus isn't a major industrial hub, it benefits from proximity to larger industrial zones in Niš, potentially experiencing some downwind impacts from industrial emissions, particularly during periods of stagnant air.

Brus experiences a continental climate, resulting in a distinct seasonal narrative regarding air quality. Winter months (December-February) are often characterized by temperature inversions, where cold, dense air becomes trapped in the valleys and basins surrounding the town, hindering vertical mixing and leading to a build-up of pollutants. This is exacerbated by reduced sunlight hours and increased residential heating, primarily using wood or coal, which releases particulate matter. Spring (March-May) brings a gradual improvement as temperatures rise, and wind speeds increase, dispersing pollutants. However, agricultural burning, a traditional practice for land clearing and crop residue disposal, can create localized spikes in air pollution during this period. Summer (June-August) generally offers the best air quality, with strong solar radiation promoting atmospheric stability and frequent convective mixing. However, occasional heatwaves can lead to stagnant air conditions. Autumn (September-November) sees a return to more variable conditions. Cooler temperatures and decreasing sunlight hours can trigger inversions, while wind patterns remain unpredictable. Fog, common in autumn mornings, can trap pollutants near ground level. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during winter and early spring, limiting outdoor activity on days with visibly poor air quality or reports of inversions. During agricultural burning season, residents should monitor local announcements and avoid prolonged exposure to smoke. Maintaining indoor air quality through proper ventilation and air filtration is also advisable throughout the year.
