I live in northern Maine, and my basement is starting to get a weird odor. It's not getting wet and there are no water issues. A friend says I need to get a dehumidifier. The basement has our laundry area and my "man cave." I was wondering what kind of dehumidifier I should buy. I've seen some that have heat and AC. Will this type of dehumidifier help the rest of the house, or just the basement? Please recommend a brand and/or model.
