In modern cities, especially in megacities like Dubai, indoor air quality is becoming increasingly important for health and comfort. One of the main sources of air pollution in offices and homes is the ventilation and air conditioning (HVAC) system. Over time, dust, germs, mold, and other pollutants accumulate in the air ducts, which not only degrades the air quality but also leads to a number of health problems and the condition of the system itself.
