Autumn has many joys: Crisp air, sweaters, piles of leaves. It also means more closed windows and less fresh air. And for those of us affected by the wildfires, good-quality air indoors is even more important. An air purifier can clean up the odor, filter out allergens, and zap germs; here are ten deals on air purifiers for all sorts of spaces.
