General description No more intrusive hot air! The 500cm Window Sealing Cloth for Portable Air Conditioners and Dryers effectively traps hot air released from your portable air conditioner's duct by blocking it between the window frame and the window itself. This window seal keeps out unwanted guests and rain, creating a "closed environment" that helps maintain a cooler room for longer. It surrounds the vent of your air conditioner, blocking the return of hot air, which enhances cooling performance and efficiency.
