The Arm & Hammer 3 pack Hanging Moisture Absorber and Odor Eliminator is your solution for continuous cleaner, fresher air. This musty odor eliminator works by attracting and trapping excess moisture to maintain an optimal humidity level. It works in the closet, laundry room, pantry, bathroom, and storage areas, where moisture is an issue. This unique deodorizer has 15% more moisture absorbing power plus the power of baking soda for odor elimination versus the leading brand. Think of it as a non-electric dehumidifier to keep areas and clothes smelling fresh, preventing damp feeling fabrics. To use this convenient, simply unwrap the moisture absorber bag and hang it in a moist area. Before too long you'll see the first drops of moisture collect in the transparent collection pocket. When moisture absorbing crystals are completely dissolved, discard and replace. Available in Clean Burst and Fragrance Free. Keep out of reach of children. Read and follow all label directions.
