Seriously though, an alternative to buying a mask (Whether proper or make-shift) is to make your own mask. Sure, you can search YouTube for "DIY face mask" but most of the designs out there are either soft cotton or hard plastic (From 2 liter soda bottles) basic coverings that will NOT protect you from contracting COVID-19 if you are going to be constantly around various, possibly infected people up close (Most of us won't as long as each of us practices Social Distancing). However, there is one design that is created by an emergency room doctor that uses a HEPA vacuum bag, the material of which filters out 99.97% of particles 0.3 microns in length just as the material in an N99 mask does ->

Update 2020/06/24: I've just learned that N100 masks filter out 99.97% of particles 0.3 microns in length while N99 masks filter out 99% of such particles. Thus, the above sentence that reads "... filters out 99.97% of particles 0.3 microns in length just as the material in an N99 mask does ..." should actually be "... filters out 99.97% of particles 0.3 microns in length just as the material in an N100 mask does ...". I'm sorry for any confusion that this may have caused.
