Bring fresh air and style to your rooms with the eclipse Lawson arm & hammer odor neutralizing blackout grommet curtain panel. Sunlight activates the embedded arm & hammer technology through a photocatalytic process which causes airborne pollutants and other unpleasant odorous substances such as from pets, cooking, smoke, must, or mold to degrade into water vapor, carbon dioxide and be neutralized. These panels will also help save money on energy costs by helping to keep your rooms cooler in the summer and warmer in the winter. Lastly, panels are noise-reducing and block up to 99% of incoming light for superior privacy.  Number of Panels: 1 Included: 1 Panel(s) Features: Energy Saving, Room Darkening, Noise Reduction Top Construction: Grommet Top Opening: 1 1/2 In Grommet Open Use: Indoor Base Material: 100% Polyester Lining: Unlined Light Filtration: Blackout Care: Machine Wash Curtain Length: 63 Inch Curtain Width: 50 Inch Grommet Color: Nickel Decor Styles: Contemporary Back of Curtain Color: Gray Material: Microfiber Curtains Type: Curtain Panels Country of Origin: Imported
