e Oder absorber . It does a great job at absorbing oders .i have a whole bed room that is a closet and I don't heat it in the winter time and I started to get get mold on some things and I got a bunch of these Oder absorbers and I've not seen any mild since . Plus I don't have any odd smell on my clothes. I can not believe how well these work . They just work great . I received these charcoal Oder absorbers at a deeply discounted price in exchange for my honest opinion.
