  • Patent number: 5874237
    Abstract: A bioaerosol collection device (BCD) includes a housing with a first opening, a second opening, and a plate positioned between the first opening and the second opening. When a vacuum is applied to the second opening, the resulting air flow through the BCD causes bioaerosols to collect on a medium positioned on a surface of the plate. The collected bioaerosols are incubated and the resulting bacterial colonies can then be counted to determine a level of bioaerosol contamination in the air.
