Adapted from our McDaniel High School Air Quality Report, this excerpt from the McDaniel report reviews sources of clean airflow in classrooms and other school rooms, basics and recommendations on air changes per hour and other measurements of clean airflow, and what effects different rates of air changes have on how clean classroom and school air is.

Clean air in schools benefits every student, teacher, and family, and it takes a community to make it happen. Join our clean air community to stay informed and be part of the movement for healthier classrooms. Together, we can make air quality in Oregon schools a model for the nation.
