Abstract Intake air filtration in swine barns has been shown to reduce disease outbreaks at the facility. While standardized test methodologies exist for evaluating filter performance, e.g., ASHRAE 52.2, the challenge aerosol and air flow conditions are not representative of a barn environment. A new filter performance test methodology was developed using a test duct configuration amenable to use in a biosafety containment facility, air flow rates relevant to a swine barn, and an organic/viral challenge bioaerosol. The test methodology evaluates filter performance for particle diameters 10 nm to 10 microns, a larger size range than typically used for such filter performance evaluations, to match conditions observed at existing swine facilities. Details of the methodology and performance of various filter types will be discussed.
