Raven CleanAir Map is an app that collects indoor air quality readings (in the form of CO2 readings) and displays it on a map. This allows the public to choose indoor spaces that prioritize clean and filtered air. This project is part of a kit (https://scistarter.org/citizen-science-kit-assessing-indoor-air-quality) that may be available at your local library (https://scistarter.org/library-locations)!
