Ordinary masks ain't good unless you are sick and want to protect others. N95 masks are good, but more for health professionals, and hard to come by. Using this #STAYSAFE system, you just have to hold your breath for 95 seconds and breath for 5 to get same 95% pass-through as N95 masks.
If you can hold your breath longer (over 20 minutes will get you to Guinness World Records), chance of breathing in the Corona Virus is less.
