The COVID$-19$ virus is passed via water droplets containing the virus when someone exhales, sings in the shower, has the giggles, etc. $($reference article link $).$ N$95$ masks filter $95\%$ of particles which are $1\mathrm{.}18$ x $10-5$ inches or larger. Use this information to answer the following questions:

What size of water droplet in nm could pass through the N$95$ mask?

The COVID$-19$ virus particle $($when it$$s all by its lonesome without a water vapor buddy$)$ has a diameter of $1\mathrm{.}25$ x $10-4$ mm$.$ Can the virus particle pass through the N$95$ mask? $($yes$,$ you probably know the answer to this one...but show me the math$)$

Carbon dioxide particles are $0\mathrm{.}33$ nm in diameter. Can a carbon dioxide particle pass through the N$95$ mask?
