Indoor Air Quality | Community Health

Indoor air quality (IAQ) refers to the air quality within buildings and structures, which can significantly impact the health, comfort, and well-being of occupants. Poor IAQ has been linked to various health issues, including sick building syndrome, respiratory problems, and reduced productivity. Common indoor air pollutants include secondhand tobacco smoke, radon, molds, and volatile organic compounds. According to the World Health Organization (WHO), approximately 3.8 million people die prematurely each year due to indoor air pollution. The United States Environmental Protection Agency (EPA) estimates that indoor air pollution levels can be 2-5 times higher than outdoor levels. Improving IAQ requires a multi-faceted approach, including source control, filtration, and ventilation. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommends maintaining a minimum of 15 cubic feet per minute (cfm) of outdoor air per person in buildings. By understanding the importance of IAQ and taking steps to improve it, individuals and organizations can create healthier and more productive indoor environments.
