NCT05942534

Brief Summary

This study will evaluate the performance of various face masks and respirators on children by examining their fitted filtration efficiency (FFE) and mask fit. It will also evaluate the impact of different types of mask modifications (for example, twisting the ear loops, tuck and tie) on FFE and mask fit, with the goal of determining how to optimize mask performance in children. It will also provide information on mask and respirator comfort and acceptability. This data will help inform public health messaging around mask choice for children and also modifications that can be made to improve fit for children who may not have access to various mask types.

Outcome Measures

Primary Outcomes (1)

  • Fitter filtration efficiency and fit factor

    To compare the performance of different mask (cloth and medical) and respirator (KN95 and N95) types and mask modifications in children, as measured by fitted filtration efficiency (FFE) and fit factor.

    First visit (1 hour)

Secondary Outcomes (1)

  • Mask and respirator comfort and acceptability

    First visit (1 hour)

Study Arms (2)

mask type assessment

The mask type assessment will compare a cloth mask, child and adult medical mask, child and adult KN95 respirator, and N95 respirator.

mask modification assessment

The mask modification assessment will compare a child medical mask, adult medical mask with and without modifications (tuck and tie, twisted ear loops), and child and adult N95 respirator.
