Why is Indoor Air Quality Important

I have asthma. We will have 2 small children when we move in. I'm concerned with air quality. I learned that carpet doubles its weight in one year from all the crap that is collected in it. A dyson won't change that. dust is not my friend. I can smell everything. I think I can smell the formaldehyde leaching from particle board furniture from Target. I just can. So that is our focus. Indoor Air Quality. that is our number one focus and it happens to be Green.
