For Those Anxious About the Mask Shortage: A Researcher's Serious Investigation into How Many Particles Can Be Captured by Paper Towels and Handkerchiefs

This video shows that you can capture a surprising number of small particles just by layering paper towels or handkerchiefs.

The video is approximately 3 minutes and 40 seconds long.

Also, for those wondering if it can't capture viruses or even smaller particles, the academic society I belong to has issued a statement, so please refer to that. Also, please watch the second, third, and fourth videos in the series above.
