1 Introduction

Indoor air quality (IAQ) in schools can affect the health and academic performance of children. Reports over the past two decades have noted that IAQ can affect respiratory symptoms, allergies, asthma exacerbation, cognitive function, attention span, and academic achievement (1&#x;12). Indoor pollutants most commonly measured in school classrooms include fine particulate matter (PM) and carbon dioxide (CO₂). PM exposure has been associated with asthma (10, 13), rhinitis (13), reduced lung function (2), and respiratory inflammation (3), and PM can contain compounds including polycyclic aromatic hydrocarbons (PAHs) that increase cancer risk (3) and pathogens (pathogenic bioaerosols) that promote disease transmission, including influenza and SARS-CoV-2 (14, 15). CO₂ serves as a measure of ventilation adequacy and IAQ. High CO₂ levels have been associated with decrements in student decision-making performance (12), test scores (16), and attendance (17), although evidence for adverse cognitive effects is inconsistent at moderately elevated CO₂ levels (e.g., &#x;ppm) (18).
