With COVID-19 cases surging around the country and winter fast approaching, this may be the most important toolkit episode yet. Infectious diseases physician Nahid Bhadelia and indoor air quality expert Richard Corsi answer every tough question about winter safety – from holiday gatherings, to indoor dining, and flu season. Understand what’s happening with indoor particles and how to make sure homes, offices, and schools can be as safe as possible with ventilation, filters, and CO2 meters. Andy and Lana team up for the episode they say they learned the most from. And be sure to stick around for a very nice surprise at the end of the show.
