Practical tip for those dealing with wildfire smoke now: you can make a very effective air filter for a reasonable amount of money using a box fan & one of those filters meant for your furnace.
Also, I’ve managed to pick up 2 of the box fans for very cheap/free from yard sales. Make sure you get a filter rated for wildfire smoke, I think this one cost about $20.
These make a huge difference in the indoor air quality.
Posting again because of the fire situation up in Canada and resulting smoke. If you’re dealing with wildfire smoke, these are surprisingly effective and relatively cheap.
Just tape the filter to the fan, making sure the air can’t sneak around the edges. I used painter’s tape, but I’m sure duct tape or similar would work just as well.
