Clean Air at School

This free, web-based hub from the American Lung Association pulls together the most widely cited science-based guidance, factsheets and assessment tools that K-12 administrators, facilities managers and school-health staff need to tackle indoor air quality (IAQ) challenges in classrooms and ancillary spaces. The page explains why children are uniquely vulnerable to pollutants such as fine particulates, viruses, mold, radon, CO₂ and cleaning chemicals, then links to step-by-step checklists for improving ventilation, filtration and source control, model policies for school boards, funding primers, and short explainer videos teachers can use with students. Quick-reference tables summarise target ventilation rates, recommended filter efficiencies (MERV 13+), and safe cleaning practices, while downloadable templates help districts launch walk-through IAQ audits or communicate with parents about air-related health complaints and asthma-action plans. Many linked resources are bilingual (English/Spanish) and highlight low-cost interventions suited to rural and high-poverty schools. Overall, the page functions as a continuously updated one-stop gateway that saves busy school leaders time when making the case for, budgeting, and implementing IAQ improvements.
