how can I get rid of humidity odor in my apartment?
Answers:
Make sure your apartment is well ventalated first off. There may be a mold or mildew issue in the carpeting and even wallpaper depending on your decor.
Use this stuff called Approach to eliminate it. Spray EVERYWHERE above your head and let it settle into the carpet, fabric, everywhere (it's waterbased and safe don't worry) and it'll clear up any stuffy biological odors you have.
Good luck!
