DO THIS NOW BEFORE IT GETS THERE!

Order a pair of countertop water distillers online (or buy locally if you can find them) along with some extra charcoal filters for a final filter to your drinking water. Don't drink unfiltered tap.

Buy a large supply of extra thick AC filters/furnace filters and change often.

Buy HEPA filter bags for your vacuum cleaners and vacuum often.

Rent - or better yet - buy some free-standing HEPA whole-house filtration fans to cover the interior of your home. Buy several replacement filters for the fans as you'll be needed them for quite some time.

Keep animals indoors as much as possible. Furry animals should be wiped down with a wet washcloth rinsed in distilled water each time they come back inside from doing their business to prevent the particles that filter down from staying on them and sickening them.

Wear N-95 masks outside.

Hose down driveway, walkways and all entrances to your home daily to prevent the stuff from getting carried inside on your shoes if you will be walking in and out - or remove shoes before entering.

And lastly, Pray!
