Hosted by our neighbors in the Granite State, please join us for an insightful webinar covering one method to tackle COVID-19 transmission:

Airborne transmission is the dominate vehicle for COVID-19. Recent guidance from the World Health Organization suggests that if a room does not meet the minimum air change rates as set forth by ASHRAE, the supplemental HEPA based portable filtration should be deployed. To help understand the effectiveness of this approach we will be hearing a presentation from Dr. Joachim Curtius from Goethe University in Frankfurt Germany. A recently publish paper by Dr. Curtius reports the efficiency and practicality of operating four HEPA filters in a high school while regular classes were taking place. Two classrooms were used, one as control with no filters, and instrumented with measuring devices that could measure from 10 nm to 10 um. The reduction in aerosol concentration was measured at more than 90% in less than 30 minutes, and the estimated inhaled dose reduced by 6x for a 120 minute class period
