Omicron: Masking and Indoor Air Quality 101

Andy enlists two experts — UC Davis Dean of Engineering Rich Corsi and “Mask Nerd” Aaron Collins — to better understand the importance of masking and indoor air quality during this Omicron wave. Fan favorite Rich returns to talk about how to think about ventilation, ways to reduce our inhalation dose, and how that’s changed with Omicron. Aaron breaks down everything you need to know about the different kinds of masks out there, including what masks are best for kids. Today's episode is a battle of the nerds, and we all come out winners in the end with practical information to help us stay safer during this Omicron wave and beyond.
