Here in HEWston, the largest, totally invisible metropolis in the Western Hemisphere, we're in a constant struggle to beat LA for the honor of having the worst air quality in USAmerica. Frequently, we beat the tar out of 'em on particulates, and lose out in the final stretch on ozone.
Plus, the cedar and the pines are pollinating of late, so I thought it possible that my charcoal activated Fram (tm) air filter was improving my olfactory experience inside my Bonnie.
Isn't it a hoot that it seems Pontiac delivered all these cars with the Passenger Cabin filter hole, the instructions absent in the manual, and no one to tell us that life could be better with a big orange box?
