Comparison of high-volume air sampling equipment for viral aerosol sampling during emergency response.

Objective: This study compared the performance of two high-volume bioaerosol air samplers for viable virus to an accepted standard low-volume sampler. In typical bioaerosol emergency response scenarios, highvolume sampling is essential for the low infective concentrations and large air volumes involved.

Design: Two high-volume air samplers (XMX/2LMIL and DFU-1000) were evaluated alongside a lowvolume sample (BioSampler).
