Commercial complexes, encompassing shopping malls, retail stores, restaurants, and entertainment venues are vital hubs of social and economic activity. These spaces attract a large number of visitors daily, creating a dynamic environment where maintaining optimal indoor air quality (IAQ) is crucial for ensuring public health, promoting comfort and enhancing the overall experience. Poor IAQ in public commercial complexes can stem from various sources, including inadequate ventilation, high occupant density, building materials and cleaning products, leading to stuffy air, unpleasant odors and potential health risks. Prioritizing IAQ in these spaces involves a comprehensive approach to ventilation, filtration and source control, creating a refreshing and healthy environment that encourages visitors to linger, shop and enjoy their time in these public spaces.
