I left the pedicure salon, started my car and drove less than 3 miles to pick up something from the store, when I stepped out of my car my feet were black... and I don't meant just from dirt, It looked like someone dumped a bucket of black paint on me from shins down. I had my AC blowing on my feet but I didn't recognize and smells that were different than before. My neighbor said it Looks like I stood behind and exhaust pipe. My car is a 2011 Scion TC and about 65,000 miles. Any ideas of what it may be? I recently got my air filter changed as well.
Cabin filters on modern cars use something called activated carbon (or at least some of them do) which is basically two paper / cotton sheets either side of a fine layer of carbon particles.
It looks to me as though your cabin filter has a hole in it and therefore is blowing carbon all over the inside of the cabin.
I'd take it back to wherever installed the new filtration and have them change it out under warranty as it looks as though it's been faulty when they've installed it and they've not noticed.
I'd also be tempted, once it's been changed, to vacuum the carpets in your footwells as they're probably thick with this fine black dust.
