【Universal Compatibility】This versatile air conditioner window seal offers a perfect fit for virtually all portable air conditioners, tumble dryers, dehumidifiers, or any appliance with an exhaust hose. It works seamlessly with windows that open to the left or right, bottom-hung windows, and even skylights (note: not designed for sliding windows or doors), accommodating window perimeters up to 400 cm. Tidy setup in your bedroom, home office, or living room—no matter your window type.
【Enhanced Cooling Efficiency & Comfort】Say goodbye to wasted energy! Our window seal effectively blocks the return flow of warm outdoor air by securely locking the hose between the window frame and the window itself. This not only reduces cold air leakage but also keeps your room consistently cooler for longer. Additionally, it acts as a barrier against insects, dust, and pollen, ensuring a cleaner, more comfortable indoor environment during hot summer days and humid nights.
