Keep the cool air inside and push the hot air out with this flexible window seal kit designed for portable air conditioners. The sealing cloth attaches around your window frame and the exhaust hose, creating a tight barrier that stops warm outdoor air from creeping back into the room.
Made from durable, waterproof nylon, the kit installs in minutes with the included adhesive fastening strip and a handy zip opening that lets you close the window without removing the seal. It is a simple, low-cost upgrade that helps your portable AC work more efficiently all summer long.
Ideal for bedrooms, living rooms, home offices and small apartments where a portable air conditioner vents through a window. Simply fix the cloth to the window frame, zip the exhaust hose through, and enjoy a cooler, more comfortable space.
