What's more, the aircon window seal kit can also prevent flies and spiders from entering the room through the window. 【Wide Application】Make sure to measure your window before purchasing to select the correct size. Specifically designed for mobile air conditioners, drum dryers, and exhaust dryers, our AC window seal kit enables these devices to operate more efficiently by expelling hot air even with the window open.
