The COVID-19 pandemic has been an unprecedented public health crisis around the world and has created novel needs in the healthcare industry. Primary among these needs is a vast shortage in personal protective equipment (PPE) such as masks and gloves. This is problematic due to the near constant of COVID-19 cases in hospitals around the United States. In an effort to meet the need for more PPE, new disinfection techniques must be found to "recycle" used PPE. UVC light has previously been used by healthcare facilities for years to disinfect surfaces such as stainless steel and are frequently used in operating room sterilization and dentist offices. UVC light's effectiveness on porous materials such as masks has not been substantially investigated prior to the COVID-19 pandemic. This work shows the effectiveness and efficiency of UVC disinfection on porous surfaces for the COVID-19 virus and other bacteria.
