DampRid Hanging Bag Moisture Absorbers attract and trap excess moisture out of the air. Think of it as a dehumidifier without electricity, absorbing excess moisture to create and maintain optimal humidity levels wherever dampness and musty odors are a problem. Time-release fragrance technology releases a pleasant scent continuously over the life of the product. DampRid Hanging Bag Moisture Absorbers are ideal for closets, but they're also great for laundry rooms and storage areas where clothes and other fabrics often collect unpleasant, musty odors. These DampRid Moisture Absorbers offer 10% more moisture absorbing power compared to 14.5-ounce bags and can last up to 60 days depending on the temperature and level of humidity. When the liquid in the bag reaches the replacement indicator line, simply discard and replace. Not for use in moving vehicles. Keep out of reach of children. Read & follow all label directions before use.
