Review: Works! - Not easy to figure out how to use an ac unit in a window like this! We have an old house so these crank completely out. So both sides need to be sealed. It wasn’t difficult to install, just use the adhesive to apply all around the window frame and then velcro the plastic pieces together. It doesn’t look the most attractive from the outside but it’s better than dying of heat! There’s normally No leakage but if there is a heavy rain, the way it seals together on the top of the window creates a pocket… so it will start to get filled with water and can leak down the sides a bit. How to solve that is to raise it up making a pitch in the plastic so it drains off the sides so it won’t collect there. The zipper opens large enough to attach the hose through. It really is the best solution for this weird type of window. Ok, the only one! Haha
Review: Great invention for weird apt crank windows - Works very well, easy setup and great use out of it thus far. Keeps any bugs and birds out of my windows. Very soft fabric , white in color with mesh parts. There is no noise canceling to this but it definitely helped my finally install my AC to my weird apartment windows! I use it to install my Air Conditioner Hose for my apartment crank windows

## Features

- ✔【Universal Fit for Multiple Window Types】Designed for a wide range of window styles including casement, crank, push-out, and skylight windows. This window seal kit fits windows with a maximum perimeter of 400CM (157 inches) and works with single or dual hose portable air conditioners from most major brands.
- ✔【Flexible Zipper Design for Any Hose Position】Unlike rigid plastic window panels with fixed hose couplers, the adjustable zipper design allows you to position the exhaust hose at different heights. This flexible structure helps align your portable AC with your window more easily and creates a secure seal around hoses of different sizes.
- ✔【Improve Cooling Efficiency】The window seal helps prevent warm outdoor air from flowing back inside while your portable air conditioner is running. By maintaining a tighter seal around the exhaust hose, it supports more efficient cooling and helps your AC operate more effectively.
- ✔【Durable Waterproof Fabric】Made from high-quality waterproof TU fabric with UV protection, this window vent seal helps reduce the entry of rain, dust, and outdoor particles while maintaining proper ventilation. The durable material is designed for reliable performance throughout the summer.
- ✔【Quick No-Drill Installation】Install in minutes without tools or drilling. Simply clean the window frame, attach the adhesive Velcro strips, secure the seal, and zip it around the exhaust hose. The removable design makes it convenient for renters and easy to take down during cooler seasons.

### ⭐⭐⭐⭐ Good Product Flexible Application
*by R***N on July 3, 2025*

The graphic on the ad implies there is a fixed form to insert two hoses. Actually it's just a series of zippers that lets you place the hoses in a convenient way. It does keep out moisture - as long as you make sure that the seal is tight on the tape side and the velcro side. Using the supplied zip ties helps to secure the zipper around the end of the hose, but self-sealing velcro tape wrapped around the end of the zipper to cover any opening helps to keeps insects out, and is less expensive to replace than zip ties. Reasonably priced, useful instructions and videos, likely to last several seasons.
