Fig. 6: The comparison of the microstructures and performance of the three face masks.
From: Microstructure analysis and image-based modelling of face masks for COVID-19 virus protection
The reusable mask has the best breathability and comfortableness (the highest facial temperature, coarse fibres and the largest pore size within fibre spacing) whereas the N95 mask provides the best aerosol filtration (the smallest pore volume, the finest fibres and the largest specific surface area).
