Final maneuver completed in fit test of three N95 filtering facepiece respirators.

<p>(A) Percentage of the final maneuver completed in qualitative fit test (QLFT) as distributed by cells in respirator fit test panel (RFTP) of bivariate design. (B) Percentage of the final maneuver as distributed by models of respirator and by facial sizes in RFTP of bivariate design. (C) Percentage of the final maneuver as distributed by cells in RFTP of principal component analysis (PCA) design. (D) Percentage of the final maneuver as distributed by models of respirator and by facial sizes in RFTP of PCA design. The tests categorized in the group “Normal breathing”, “Deep breathing”, “Turning” (turning head side-to-side), “Moving” (moving head up-and-down), “Talking”, or “Bending” (bending over) were those wherein the participants passed the named maneuver but failed on the next one. The group “None” denotes the tests that the participants failed on the first maneuver.
