ASU's Clean Indoor Air Project

Our team is bringing cleaner air into Arizona classrooms by building, studying and deploying DIY portable air filtration units to communities in need. We aim to increase awareness about the importance of indoor air quality and help every classroom have access to a portable air cleaner to remove airborne viruses, wildfire smoke, allergens and air pollution.

ASU’s Clean Indoor Air Project is a public health initiative to: 1) increase awareness about the importance of indoor air quality and empower communities to minimize their inhalation risk; 2) expand access to portable indoor air cleaners through an affordable DIY air filtration solution; and 3) advance the science of measuring indoor air quality. 

Investments in air filtration and ventilation can reduce student absences due to illness – both during a pandemic and in more normal times.  Improving air quality has demonstrated benefits: it reduces the risk of respiratory diseases, leads to fewer missed school days, improves concentration, and supports better overall health outcomes. All students and staff can benefit from cleaner indoor air.

The team of students and community volunteers have been building DIY air filtration units, called Corsi-Rosenthal boxes (CR box), for local Arizona schools to improve indoor air quality and reduce exposure to virus particles by increasing indoor air filtration and ventilation.  C-R boxes have been shown to work as effectively as portable HEPA filters at a fraction of the cost. This critical tool can help reduce virus transmission in schools, and consequently decrease potential COVID-19 cases and hospitalizations. 

As of April 2022, with the support of the community and through generous individual donations, we have deployed more than 300 CR boxes to over 200 schools in more than 20 cities across Arizona. 

Your donation will be used to purchase supplies to help schools in need across Arizona. Community build events also provide a unique opportunity for K-12 students to participate in a hands-on STEM project that benefits public health. 

Thank you for bringing cleaner air to Arizona classrooms!
