【COOL DURING SUMMER】 - The window seal blocks the return flow of hot air by sealing the hose between the window frame and the window itself. At the same time, it reduces cold air leaks and keeps your room cool for longer, providing you with a cool and comfortable living environment.

【REDUCE ENERGY CONSUMPTION】 - Enjoy eco-friendly living! This window seal helps reduce energy consumption and lower carbon dioxide emissions, which are particularly high in summer due to the widespread use of air conditioning. Protect the environment while saving energy and reducing electricity bills!

【STRONG WATERPROOF ADHESIVE】 - The air conditioner window seal is washable and waterproof, protecting against rain on wet days and also keeping out insects and mosquitoes.

Supplied with strong adhesive tape, you no longer have to worry about the tape coming loose.

【EASY TO INSTALL】 - No tools or drilling required. Everything you need comes with the window seal! Simply apply the hook-and-loop tape to the inside of your window frame and to the window itself, then attach the window seal to the hook-and-loop tape. Open the zipper and place the air hose outside the window. Then, tightly close the zipper around the hose. The window remains fully functional and can be opened and closed as usual. Additional cable ties are included with the product for extra support and fastening.
