To study the effects of relative humidity (RH) on TGEV collection by the filters and samplers, the virus was nebulized into air at 30, 50, 70, and 90% RH. To measure the degree to which the nebulizers generated airborne viruses that could be sampled and remain viable, aerosolization efficiency, g A , was calculated in the same way as Adams et al. The recovery of TGEV from the test filter can be calculated in two ways: (1) relative to the airborne virus concentration, R a , and (2) relative to the nebulizer suspension concentration, R n . TGEV was nebulized, then sampled using AGI-30 impingers and BioSamplers, and finally collected on an HVAC test filter to measure the effects of nebulization stress and the recovery of viable virus from the filter.	./cache/cord-282344-o1rkx2z4.txt	./txt/cord-282344-o1rkx2z4.txt
