Description
This study evaluated the consistency between two quantitative fit test devices with different methods of ambient aerosol counting. Three types of respirators (N95, half mask, and full facepiece) were worn by 50
participants (male, n 1⁄4 25; female, n 1⁄4 25), PortaCount (Proþ 8038) and MT (05U) were connected to one probe to one mask, and fit factors (FFs) were measured simultaneously with the original and modified
protocols. As a result of comparing MT FFs with PortaCount FFs as references and by applying for the pass/fail criteria (FF 1⁄4 100), the consistency between the two devices for half masks and full facepieces
was very high. N95 was somewhat weaker than the two type of respirators in the consistency; however, the correlation between the two devices was very strong (p < 0.0001). The results showed that an FF of 100 as measured by PortaCount was likely to be measured as 75 by the MT. Therefore, when performing the fit test for N95 using the MT and pass level of FF 100, a certain level of adjustment is necessary,
whether end-user or putting a scaling factor by manufacturer.
