Is there an air sampling method for SARS-CoV-2?

There are air sampling methods for the SARS-CoV-2 (COVID-19) virus in general. However, the regular filter cassettes will not work because their pore size is larger than virus particles. Liquid impinger with proper medium is a suitable method. There is a study of air sampling of SARS-CoV-2 using SASS®2300 WETTED-WALL AIR SAMPLER at 300 L/min for 30 minutes. There is another study that used polytetrafluoroethylene (PTFE) filter cassettes for taking air samples. However, we have not validated a testing method for air samples.
