Why is my nose sore and always congested in my apartment, what should I do?

I live next to a busy freeway ramp, constant traffic, sirens, its very bad. Here in this aoartment I noticed air is very dry. I bought a humidifyer but it makes things worse. If I don;t use it I have a swallen face and pupils and my nose is constantly cogested and clogged and sometimes well most of the time I have sore nostrals or areas around my nostrals (not sure I spelled it right) are sore. What can I do to make things better. I also noticed that when I wake up I notice myself catching a breath. My breaths are short when I wake up also due to poor ventilation. What is the best way to fight this guys? thank you!!!
