      <subfield code="a">The purpose of this study was to evaluate one specific engineering control deveice that is presently on the market, a Duo-Flo BioClean unit for its effectiveness at reducing laboratory airborne allergen concentrations. Airborne allergen concentrations and particle size distributions were investigated with the control unit operating in both the positive and negative pressure modes</subfield>
