Improving Indoor Air Quality Through Effective HVAC VentilationIndoor air quality (IAQ) is influenced by a variety of factors, including outdoor pollutants, ventilation systems, and the presence of indoor sources like cleaning chemicals, allergens, and building materials. Poor IAQ can directly impact the health and productivity of individuals within a building. For instance, exposure to airborne particulate matter, such as that found in wildfire smoke, can lead to respiratory issues, especially for vulnerable populations such as children, the elderly, and those with pre-existing health conditions.
