【Efficient Exhaust of Warm Air, Prevents Backflow】This air conditioning window sealing kit helps exhaust warm air and prevents backflow. It cools the room more efficiently, reduces energy consumption, saves on electricity bills, reduces CO2 emissions, and protects the environment. In addition, the sealing kit also prevents flies and spiders from entering the room through the window. 【Wide Applicability】Our window sealing kit is designed for portable air conditioners, tumble dryers, and exhaust dryers, ensuring these devices operate efficiently and exhaust warm air even when the window is open. Suitable for inward-opening, tilt-and-turn, and casement windows, but not for sliding windows. Currently available in 6 sizes: 300cm, 400cm, 500cm, 560cm, and 600cm. Please measure your window size before ordering. 【Easy Installation】The package includes the air conditioning window sealing strip, instructions, tape, and cable ties. No drilling or special tools are required. Installation is quick and easy by following the instructions. Open the window, apply tape to the window frame, apply the air conditioning window sealing strip, and then secure the hose through the sealing strip using the zipper. Cable ties can be used to secure the hose if necessary. 【Durable, Waterproof, and Windproof】Our air conditioner window seal is made of durable 210T polyester fabric with a PU coating, providing waterproof and windproof protection. Besides regulating airflow, it also protects the indoor environment from dust, dirt, strong winds, heavy rain, and insects. Please note: There may be a slight gap between the zipper and the hose, but this does not affect its function. 【Portable and Reusable】Our portable air conditioner window ventilation kit is not for single use. After summer, you can wash it with water and reuse it the following year (the packaging bag can be used for storage). With zippers at both ends, you can adjust the opening size according to the hose diameter, making it suitable for single or double-tube portable air conditioners.
