    Snippet: were qualitatively fit-tested (QLFT) using Occupational Safety and Health Administration (OSHA) fit test protocols (see Methods for details) (12) . We also carried out quantitative fittesting (QNFT) using OSHA protocol requirements. QNFT employs condensation nuclei counting technology to measure aerosol concentrations outside and inside the facepiece to determine a user fit-factor.

    Document: were qualitatively fit-tested (QLFT) using Occupational Safety and Health Administration (OSHA) fit test protocols (see Methods for details) (12) . We also carried out quantitative fittesting (QNFT) using OSHA protocol requirements. QNFT employs condensation nuclei counting technology to measure aerosol concentrations outside and inside the facepiece to determine a user fit-factor. Five new respirators of each facepiece were subjected to QLFT, followed by QNFT. Successful QLFT and QNFT results were achieved for all five models of N-95 respirator facepieces shown in Table 1 .
