As kids head back to school, many parents and teachers worry about air quality amid viruses like COVID-19. Rather than waiting for your school’s HVAC system to get replaced, what if you could build something that circulates air to the standard of an intensive care unit room for under $100 and in less than an hour? Engineers and air quality experts Richard Corsi and Jim Rosenthal have designed just a product and teach Andy how to make one.
