This week we welcome back Francis “Bud” Offermann for a discussion of ventilation, air filtration and COVID 19 Avoiding the Snake Oil Salesman. Mr. Offermann is president of Indoor Environmental Engineering, a San Francisco based IAQ consulting firm. Prior to starting up Indoor Environmental Engineering, Mr. Offermann was a Staff Scientist with the Building Ventilation and Indoor Air Quality Program at Lawrence Berkeley National Laboratory. He has been a recipient of research grants regarding building air quality and ventilation field studies, tracer gas techniques, contaminant emission rate measurements, and performance testing of air cleaning devices. 

 

Mr. Offermann served as an expert witness for the U.S. Federal Trade Commission regarding the performance claims found in advertisements of air cleaners. He also provided consultation to the American Home Appliance Manufacturers (AHAM) during the development of AHAM Standard AC-1, which is used to measure the Clean Air Delivery Rates (CADR) for portable air cleaners. He was also a past chairman of ASHRAE TC2.3 and SPC-145 committees for gas phase air filters and a corresponding member of ASHRE TC2.4 and SPC-52.2 for particulate air filters. Mr Offermann will discuss the impact of air filtration on indoor airborne concentrations of SARS-CoV-2, including what types of air filtration work and what types pose potential health risks.
