Does anyone have suggestions for keeping particularly pot smoke from entering my home? The scent is horrific and it makes my head hurt. It is far enough away that I don’t think it is actual smoke, but the odor is intense. I want to enjoy my home as much as they clearly enjoy their new screened in porch. Unfortunately, the same cannot be said for me enjoying my own yard.

No windows in this room, but there is a fireplace and a door.

Also, would an air purifier actually work?
