Performance measurement of capture mask, including characterisation of full operating performance

This report from theme 2 researchers of the PROTECT NCS, details experimental studies designed to investigate the performance of a new facemask design with impactor plate capabilities for segregating aerosols and droplets by size.

This includes collecting and analysing the particle size distributions, temperature and relative humidity monitoring in each section of the face mask using human subjects.

Key findings from the study are: the mask effectively segregates the particle size in some subjects; there is a significant ‘natural variability’ between human subjects in particle size distributions in time and space, and; facemask measurements demonstrate distinct differences between mouth and nose breathing.
