Review: Works great - Soo thankful this product was made for side open and crank open windows. Works great and really keeps the hot air out. Can be a bit of a challenge setting up depending on the size of your window but once it’s done you’ll be thankful you bought it.
Review: Perfect to fit any hose with the zip mechanism, keeps hot air outside and allows AC to do its job! - I buy a new one of these each year, as they can get kind of gross after being exposed to outside for many months. The one I previously ordered changed their design to have a “universal” hose attachment, which of course did not fit the hose of my AC unit. I came back to desertcart to find one that has the zipper style opening and found this product. I don’t ever use the Velcro tape that comes with these, because I find the adhesive usually doesn’t hold up and seems to dissolve from heat-I buy the strong outdoors Velcro tape and it works perfectly with this! Setting it up was a pretty straightforward and easy process, and now that it’s been up a couple of months, I can rest assured that it is doing its job. It has been holding up wonderfully so far-the zipper stays taught around the hose exiting to the outside, and it is doing great at keeping the hot air outside instead of inside. I highly recommend measuring to ensure you get the right size, I measured and the fit was perfect. For these weird French windows, I absolutely recommend this product to set up your portable AC! They’re also quite easy to take down when summer is over, thought with the Velcro I have been using, I definitely have a lot of adhesive left behind that I will eventually need to address, but it’s totally worth it to be able to keep my apartment cool during the summer!

### ⭐⭐⭐⭐ Best option so far
*by A***R on June 22, 2026*

I have casement windows that open outward. My home does not have central air so this has been very helpful with our portable AC units. It’s not perfect, but it’s the best option that I’ve come across thus far. With most AC venting, this will pose a security risk if you are not in a safe area as the sealer is Velcro on. I have been able to take mine off as it is Velcro on, and my window still shuts with the Velcro adhered to the window. You do have to stick the Velcro to your actual window, so this also poses a risk at damaging the windows with the adhesive. Instructions were not very clear so I watched the video and that was helpful.
