Clearing the Air: The Movement for HEPA Purifiers in Classrooms
In a recent trend to improve indoor air quality, multiple states across the US have been finding ways to put HEPA purifiers in their schools.
With funding from CDC’s American Rescue Plan Act of 2021, Illinois launched a $30 million program to distribute air purifiers in Illinois schools .
Colorado and New Jersey also have statewide programs providing free HEPA purifiers in schools. With advocacy from Indoor Air Advocates , a school district in northern Alabama received funding to add two HEPA purifiers in every classroom .
Bring HEPAs into YOUR State:
According to a recent CDC report , substantial federal funding  is available for ventilation improvements in school buildings. These improvements reduce transmission of COVID-19 and other viruses, and have been shown to improve students’ academic outcomes.
The CDC concludes:
“Ventilation is part of a comprehensive approach to reducing COVID-19 spread and maintaining safe, in-person learning. …Undertaking ventilation improvements now might lead to far-reaching improvements in student and staff member health outcomes. Ensuring equitable access to resources, support, and other facilitators of ventilation improvements is important.”
The CDC’s updated Ventilation in Buildings Guidelines  recommends HEPA purifiers, DIY air cleaners (aka CR Boxes ), CO2 monitors, and masking for children ages 2 and above to reduce chances of infection and transmission at school . ASHRAE  recently published Control of Infectious Aerosols , which includes minimum indoor air standards to reduce COVID-19 in school settings.
