As schools and offices reopen, HEPA filters are likely to become unavailable just as UV lights and ozone generators did at the beginning of CV19. Sooo, I'm going to hedge my bet that my daughter's in-person teaching will be postponed further and send her a well-rated HEPA filter while Amazon still has them.

Yes, but I don't spend 6 hours just inches away from my new best friend when I'm at the grocery store. Still, I'd rather be on a plane than a bus or a train. I was going to say "or a hospital" but of the five friends and family who are healthcare professionals working daily with Covid patients, only one has gotten Covid.
