Research establishes a direct link between classroom air quality and student attendance rates through a comprehensive study of 144 classrooms across 31 Midwestern elementary schools. The findings provide compelling evidence that improved ventilation and lower PM2.5 levels significantly reduce illness-related absences, even at pollution levels previously considered acceptable.

• For every 1 L/s/person increase in ventilation rate, classrooms experienced 5.6 fewer absence days annually
• Average school ventilation rate (5.5 L/s/person) fell below ASHRAE's recommended standard of 7 L/s/person
• Each 1 μg/m³ increase in indoor PM2.5 corresponded to over 7 additional absence days per classroom per year
• Negative health effects occurred at PM2.5 levels below previous "acceptable" thresholds (mean: 3.6 μg/m³)
• Investing in school HVAC improvements represents a direct intervention to improve student attendance and achievement
• Benefits extend beyond education to public health, academic equity, and economic advantages for families
• Improved ventilation and filtration systems build resilience against future airborne health challenges
