No, seriously, I am completely WRONG and you should all go out and buy
pallets of alleged HEPA filters for your house and your car and your
bird cage and ash tray and coffee maker and whatever the Hell else
they're making them for these days. Lords know you gotta capture
those microscopic pathogens no bigger than 0.00003" while clouds of
particles ten thousand times bigger are wafting through every window,
door, vent, hole, crack, etc in your house. Buy the really really
expensive ones. They work even better. Jinkies!
