What is the best way to remove musty smell? I hear that dehumidifiers do a good job. I am not sure where the smell is coming from as there doesn't appear to be mold anywhere, wet or discolorations. I am beginning to think that perhaps it is from the heating units (steam radiators). The apartment is a converted house that is almost 100 years old. I read that dehumidifiers and odoban http://www.odoban.com/products.php do a good job of removing the musty smell. Any recommendations on a dehumidifier for a ~1000 SQ foot space?
