Description

This portable AC window seal kit provides a simple way to connect an exhaust hose to an open window while reducing unwanted air exchange around the opening.

The seal is attached around the inside perimeter of the window frame and sash using fastening tape. After the window is opened, the portable air conditioner exhaust hose is passed through the zipper opening and the zipper is tightened around the tube.

Compared with leaving a window partially open around the exhaust hose, the sealed fabric structure helps limit hot air, insects, and light rain from entering through large exposed gaps.

Its flexible dual-zipper design also allows the hose position to be adjusted more easily, making the kit suitable for a variety of portable air conditioners, tumble dryers, dehumidifiers, and other appliances using exhaust hoses.

Applications

Portable Air Conditioners	Casement & Outward-Opening Windows	Bedroom & Home Office Cooling	Temporary / Rental Property Installation
Creates an exhaust outlet for portable AC hoses while helping reduce hot-air backflow around the window opening.	Suitable for casement, skylight, outward-opening, and selected pivot-style windows where conventional rigid window panels may not fit.	Ideal for bedrooms, living rooms, apartments, and home offices using portable cooling equipment during warmer seasons.	No-drill installation makes it suitable for rented apartments, temporary cooling setups, seasonal use, and locations where permanent window modification is undesirable.

The same sealing concept may also be suitable for portable dryers, dehumidifiers, and other appliances using compatible exhaust hoses, depending on hose size and operating temperature.
