CV size is 125nm; good air filters only catch 1000nm particles and non-medical grade masks don't stop it either. And if you do get sick it won't be like the flu - it will likely be worse, much worse.

Yes, but we are not trying to filter out individual viruses. What you really trying to filter out are droplets that carry the viruses. The droplets are much bigger and hence more likely to be captured by more primitive filters. Bigger the droplet, more likely it will be intercepted. Note the bigger the droplet the more likely it will carry a greater load of viruses and more infectious.

Think about it.
The safest thing is to stay home. Order groceries online and practice total isolation for months and hopefully you will not go stir crazy. I know I would.
Luckily, soaring is not dead everywhere.

There is increasing evidence that most COVID transmission is airborne:

This is different from other infectious diseases that are transmitted by touching an infected surface. One reporter infected 4-5 friends at lunch and none touched any of the others or their food, plates or utensils. Wearing a mask does not protect you from an infected person - it protects others from you. CV size is 125nm; good air filters only catch 1000nm particles and non-medical grade masks don't stop it either. And if you do get sick it won't be like the flu - it will likely be worse, much worse.
