I live right next door to a laundromat. My apartment window is next to the air vents on top of it. How dangerous is this to consistently breathe in?

Uncertain risks. How dangerous is constant, indirect exposure to hot dryer output, with modern fabric softeners and anti-static chemicals? I don't think the answer is known, but here is an article on the topic: www.Ncbi.Nlm.Nih.Gov/pubmed/10872633 it said there were irritating effects from the chemicals, but that doesn't explain much when one is asking about a human's exposure in a specific real-life situation.
