#COVID19

COVID-19 is caused by a virus, not a bacterium. A virus is on average about 100x smaller than a bacterium. An airborne virus is going to easily travel through the pores of your cloth mask, which are substantially larger.

Viruses are measured on a nanometer scale.
Pores in fabrics are measured on a micrometer scale.
What’s the difference?

1 micrometer = 1000 nanometers.

COVID-19 diameter size = 100 nanometers = 0.1 micrometer.

Typical pore size diameter of various woven cloth fabrics = 10-45 micrometers.

10 micrometers = 10,000 nanometers.

COVID-19: 100 nanometers
vs your mask: 10,000 nanometers

100 COVID-19 viral particles can fit end to end along the diameter of just one fabric pore in your cloth mask.

On average, 7,850 COVID-19 viral particles can fit through EACH PORE of your mask.
