If you have central air distribution put your fan on circulate through a #12 (removes fine smoke particles) air filter. Use an N95 mask outdoors and tell your friends it’s not for Wuhan but smoke.
Room size air purifiers work also. You can make your own with a fan and a HEPA filter.
Last year our windows leaked bad enough we had soot on every window sill.We had weeks of bellowing smoke. We have new windows this year.
I’m on the Oregon Coast and sooner or later the winds will shift and we will get smoked.
Thank you.
I have our central air running through a not-so-cheap filter continuously. The air in the house is MUCH better than outside. I don’t even want to be outside.
I hope the smoke abates before the wind shifts for you. This is almost the slow-motion version of Pompei.
