Kind of crazy in metro Detroit. We went out to lunch and then Kensington Metropark thinking we would take a hike, but when we saw/smelled the haze we bailed. You could not even see the other side other the lake, which is less than a half mile.
Came home, closed all the windows, and we are running the furnace/AC fan to filter the air. No need for AC as it is like 65.
I have a HEPA Air Purifier that I usually run in the basement. It usually runs a couple of minutes and then says, "Green Light, we are good, breath easy." I took it upstairs today and about 5 minutes after plugging it in, it was like, "Dude, you are killing me. Redlight, redlight, abort, abort, change filters immediately."
