Conclusion

The use of multiple features in the development of face panels is likely to be inherently better than the use of just facial height and width, but it is not yet well understood which features are directly relevant to fit and how they can best be combined.


Recommendation 4-7: Utilize Multiple Features in the Development of Face Panels.


NIOSH should examine the potential effects of a nonlinear relationship between respirator fit and facial dimensions.
