Indoor air quality (IAQ) in schools is not just a comfort issue; it’s a critical health and learning issue. With half of our nation’s 115,000 schools report problems linked to indoor air quality, the impact on student health and academic performance cannot be overstated. Young students, who are particularly vulnerable to pollutants due to their developing bodies and the significant amount of time spent indoors, face increased risks from airborne contaminants that can provoke a range of respiratory issues, allergies, and other health problems.”
