This guide from the American Lung Association provides a comprehensive overview of how indoor air quality (IAQ) affects student health, academic performance, and school operations. Developed in response to heightened concerns during the COVID-19 pandemic, it outlines the importance of ventilation, filtration, and contaminant monitoring in school settings. The guide explains the specific impacts of poor IAQ on students—especially those with asthma—linking air pollutants to absenteeism, decreased cognitive function, and long-term respiratory risks. It identifies key pollutants, including carbon dioxide, particulate matter, VOCs, and radon, and offers practical, low-cost solutions schools can implement to improve IAQ, such as opening windows, optimizing HVAC systems, and using HEPA filters. Additionally, the guide details federal funding opportunities—including CARES, CRSSA, and ARP funds—for school districts to access resources for air quality improvements. With clear action steps, links to technical support, and educational modules, this guide is an essential resource for school administrators, facility managers, and policymakers focused on creating healthier school environments.
