Designed to hang in closets and small enclosed spaces to protect items and fabrics from excess moisture that causes damage and spotting. Activated charcoal not only prevents mold and mildew stains and musty odors by eliminating excess moisture, but also absorbs and removes odors from the toughest sources such as cooking, garbage, bathrooms and diaper pails, creating fresher, cleaner, odor-free indoor air. It can be used in any room, closet, storage area, or locker. Lasts up to 60 days.
