This webinar was originally presented on November 3, 2021. Dr. Marwa Zaatari, PhD, Partner at D ZINE Partners and a member of the ASHRAE Epidemic Task Force, will provide the science of COVID-19 transmission and guidance recommendations for reducing airborne infectious aerosol exposure. She will discuss multiple layer defense strategies and debunk myths regarding ventilation, filtration, air cleaning, as well as physical barriers

Learning Objectives:

By the end of this webinar, participants will be able to:

  • Support the science behind COVID-19 airborne transmission
  • Apply updated ASHRAE recommendations to reduce risk of aerosol exposure
  • Differentiate between proven and unproven technologies to reduce exposure risk
