New Air Purifiers Filter at Least 90% of COVID-19-Carrying Particles, Researchers Say
An army of do-it-yourselfers is trying to clear the air of COVID-19. One group at the University of California, San Diego, is building 250 homemade air purifiers for classrooms and labs around campus, and they say their box-style purifier filters at least 90% of the particles that carry the virus. WOW!!!! That is so cool!
