Date & Time
An extraordinary shortage of commercially available medical masks and N95 respirators, which the global healthcare community has experienced and continues experiencing during the COVID-19 pandemic, presented several major challenges. Among them are widespread re-use of disposable protective devices, deployment of various methods to decontaminate them, utilization of homemade/improvised masks in an effort to protect workers and general public exposed to the coronavirus, and a lack of fit testing due to tremendous increase of number of mask/respirator wearers. These and other issues were addressed in research conducted by the University of Cincinnati’s Center for Health-Related Aerosol Studies.
- Review recent findings on filtering efficiency of various masks and respirators used during the COVID-19 pandemic to reduce exposure of workers and the general public to airborne viruses
- Discuss breathability of different filter materials
- Describe the effect of decontamination on the performance of respiratory protective devices and the effectiveness of homemade masks
