Off Topic ... Surviving heavy smoke
If the Moderators will indulge me for a few days before deleting this, I would like to offer a few suggestions to our members on the East Coast who are suffering under the heavy smoke from the forest fires in Canada, based upon my own experience with forest fire smoke out here in Colorado.
If you can still find one, get a large air purifier and run it 24/7. We got a Dyson from Best Buy a few years ago, and it really works. If money is no object get one for your bedroom and one for your living room.
Get the highest rating number furnace filter you can find and install it. The cheap ones are numbered around 1080. Try to find a 2500, but if necessary settle for a 1900. Run your furnace fan 24/7. Get a couple just in case this lasts and you need a spare. If the weather changes and the smoke blows out you can take it out a few days later, after the air in your house is clean, and save it for possible future use. We had a whole Summer of this one year.
Close your windows tight as if you were shutting them up for the winter. If necessary use that blue painter's tape on leaky ones.
Wear a mask outdoors.
