    Viruses are much smaller than even the smallest dust particles we worry about, so no, that's not going to help you much at all. Masks are only indicated for folks who actually have the virus, too.

    The most expensive tool is the one you buy "cheaply" and often...

    The Covid 18 virus is .1 micron & HEPA filters catch 99.97% down to just .3 micron.

    Viruses don't just free float. They are attached to drops of mucus and such. So yeah, your dust hood will be effective.
    That's why being 6' apart is reasonably safe; the carriers are heavy enough to drop out over that distance.

    Yes, it will probably be effective against the droplets that convey the virus from person to person, however this is not a DIY kind of thing. If you're in a high risk situation, eg caring for a child, partner, or parent who is infected please get advice from your doctor and/or town/county health officials, don't just wing it. They can probably help you with better personal protective equipment and, more importantly, training to use it correctly. If you just want to wear it to the grocery store it probably won't cause any harm as long as you wash your hands and don't touch your face.

    You mean besides everyone in the store freaking out?!?

    "Design"? Possibly. "Intelligent"? Sure doesn't look like it from this angle.
