[Adjustable Universal Size]Our air conditioner seal has sizes of 25 x 92cm so that you can adjust the length according to your needs. Customized for horizontal or vertical sliding windows (single-hung windows and double-hung windows), it matches all portable air conditioners or air dryers and can accommodate up to 3 air hoses. [Prevent Cooling Air Escaping]The window seal is specially made of a special fabric for heat insulation and added with a new heat-insulating whitening process on the surface. It can not only block the cold air loss from the air-conditioned room, but also reflect outdoor sunlight and heat to prevent hot air from returning, which can actually make room temperature cool quickly, save energy and money. [Seal Window Totally]With high-quality material and widened firm sticker, there is no space while sticking and installing. Using the window seal will better prevent cold air from dissipating and insects from entering, which plays great protective effects. [Detail]We will set a precise cutting and routing area on the air-conditioning cloth, which assures that you can adjust and cut it freely to avoid offline deformation after trimming. In addition, the texture processing at the outlet can prevent a space from arising near the zipper to make the tape fall off after air hose being inserted. [No Drilling & Easy to Install]1. attach the loop tape to the window frame and stick the window seal along the tape. 2. open the zipper to extend the air contioner hose out of the window. 3. close the zipper and tie them together with included zipper ties to get better sealing effect.
