One of the biggest sources of air toxicity in your home comes from your garage. A Canadian health study found that homes with attached garages had high levels of benzene (a chemical from gasoline), while homes without garages had little to none. To prevent toxins from leaking into your home, never start up a car in a closed garage, and don’t start lawnmowers, motorcycles or chainsaws, either. Keep the door from the garage to your home closed, and make sure the seal is as tight as possible.
