I used to just listen to weather report, now I check the air quality report everyday (MN Pollution Control). In Minnesota one couldn't go out in the winter because of the cold and ice, and now in the summer we can't go out because of the poor air quality!
I have a high-quality filter for my air/heating unit (additional benefit less dusting!), and in my car I asked for a Hepa filter. I think I will also get a separate room air purifier.
