Reducing the risk of SARS-CoV-2 and flu transmission in the classroom: DIY techniques for assessing and improving indoor air ventilation and filtration
Don Blair, Edge Collective
Category: STEM Ed Institute Seminar
In the last few years, improving indoor air quality has become a major global public health concern. In this seminar we’ll present both 1) a simple method for assessing a classroom’s indoor ventilation rate using CO2 monitors, with reference to recently published recommendations for mitigating SARS-CoV-2 transmission; and 2) a low-cost, easy-to-build DIY air purifier design that can remove virus-laden particles from indoor air spaces at a significant rate. We’ll finish the seminar with a ‘live build session’ in which we’ll demonstrate the construction of a DIY air purifier, and use a hand-held anemometer in order to estimate its potential impact on indoor air quality for classrooms of various sizes. Throughout the seminar, connections to STEM pedagogy will be suggested and solicited.
