This article introduces techniques used to investigate bioaerosol hygroscopicity, review hygroscopicity of bioaerosols reported in the last thirty years, and compares difference in hygroscopicity for various bioaerosols. Bioaerosols in general show moderate hygroscopicity: hygroscopic growth factors at 90% RH were found to vary between 1.04 for fungal spores and 1.22 for bacteria, and mass growth factors at 90% RH were found to be in the range of 1.30~1.55. Finally, we outline important questions which remained to be answered in this field and also propose some future research priorities.
