Window Sealing Cloth for Portable Air Conditioners and Clothes Dryers. Works with all portable air conditioning units. Easy installation.

NO MORE INTRUSIVE HOT AIR - The window seal keeps the hot air expelled from your portable air conditioner's hose out by blocking it between the window frame and the window itself. Our window seal prevents unwanted guests and rain from entering and provides a "closed environment" that helps keep your room cooler for longer.

BOOSTS COOLING PERFORMANCE - Enjoy a cooler environment in the summer with our window seal! Our product seals around your window even when it's open. It encircles your air conditioner's exhaust hose and blocks the return of hot air, allowing your portable air conditioner to be more efficient and cool your room faster.

REDUCES ENERGY CONSUMPTION - Love the Earth! This window seal helps reduce energy consumption and carbon dioxide emissions, which is especially important in the summer due to the widespread use of air conditioners.

By preventing hot air from circulating in your room, the window seal helps you save on your energy bills! EASY INSTALLATION - NO DRILLING REQUIRED. Everything you need is included with your Window Seal! Simply apply the adhesive tape to the inside of the window frame and to the window itself. Attach the sealing fabric to the tape. Then, open the zipper and place your air conditioner hose outside the window. Finally, close and tighten the zipper around the hose. It's that easy.
