Just be careful when you get one. The little cheap dehumidifiers for closets don't work well-they're called thermo-electric dehumidifiers and they don't utilize compressor technology. I would be sure to get one big enough to dehumidify your "lung" room and not just the closet. Any 20-30 pint dehumidifier should be good. I've been using a small Homelabs dehumidifier every day for the past year, keeps it right at 50%, no problems with it whatsoever. Good luck!
