Hi all, I live in a suburb of Cleveland, OH and lately the air is so full of smoke and pollution I wonder if I will need to sell my home. I have inquired with the city and fire department and they say it might be some illegal incinerators being run at night. There is a shopping center nearby and I see lots of either smoke or steam being exhausted after dark. I am wondering how to get to the bottom of it for my own sake. I myself have severe breathing problems and have friends with children with asthma and this situation isn't healthy. I have air cleaners in my house on several levels - but I love to open my windows - I love fresh air. I also love to take walks when I can with my dog. It used to be great here - but something has changed. So if anyone has run into a similar problem in their city - and has some troubleshooting ideas - I am all ears! Thanks!
