According to the U.S. Environmental Protection Agency (EPA), approximately 20% of the U.S. population spends their days inside elementary and secondary schools. School administrators and authorities have the daunting task of ensuring a healthy and conducive environment for students and staff within educational facilities. Not the least of their concerns is ensuring good indoor air quality (IAQ). The American Lung Association says improving IAQ in schools can result in higher standardized test scores, reduce the spread of respiratory illness, and reduce absenteeism.
However, schools encounter unique difficulties in ensuring good IAQ due to high occupancy; diverse space use; and potential sources of air issues, such as in classrooms, cafeterias, gyms, art rooms, and labs. Additionally, tight budgets can impact regular maintenance and cleaning practices, further complicating efforts to maintain a healthy indoor environment.
