I need some opinions as to what I can do to reduce the humidity level in my garage/basement, I'm not sure what the humidity is but cardboard boxes are getting soft and the paper items aren't crisp and I don't want to have ruined items... I have a 3 car garage/basement that is roughly 2400 sq/ft that has a 12 ft ceiling. I looked into dehumidifiers today and the ones for a space that size hurts to even look at the price. Do I have any options when it comes to this? The space is completely open other then a small unfinished bathroom and a utility closet.
