This reduces general energy consumption, as the room cools down faster and maintains a stable temperature in the long term. At the same time, it can prevent the flying insects and spiders from entering the room through the window or window seam, and also prevents the entry of rainwater. - Save Energy-Protect the Earth: Loves the earth, this mobile air conditioning window seal helps to reduce energy consumption and reduce carbon dioxide emissions, which is particularly high in summer due to the massive use of air conditioners. LYUNIT Window seals for mobile air conditioners are the perfect choice for household. It can save your funds in electricity and environmental protection. - Easy to Install-No Drilling Required: Stick the supplied adhesive tape to the window frame, attach the air conditioning window seal to the window and frame and you're done. The window seal for air conditioning reliably prevents the return flow of warm outside air into the air-conditioned interior and directs the warm air from the air conditioner to the outside. - Super Zipper Function: For maximum hold of the climate hose. The window seal has extra strong zips that prevent automatic opening of the closure when using the climate hose. Additional support and attachment are included with the product. And you can open or close the window at any time without removing the window seal. - General AC Window Seal: The air conditioner window seal is suitable for all portable air conditioners. The material of the window seal air conditioner is durable, UV-resistant. The air conditioner window seal fits window with a maximum perimeter of 400 CM.
