Gruntbear Universal Window Seal for Portable Air Conditioner, Portable AC Window Seal Kit, Hot Air Stop Air Exchange Guards with Zip and Adhesive Fastener Works with Tumble Dryer (400cm/157inch)

lf you have a casement window that pushes out when you open it, then it’s basically the opposite of what they’re telling you. I think the picture I have attached is how they want you to seal the window with the narrow pointy side on the bottom of window and top, and the larger, wider opening with zipper in the middle for the hose but I’m not sure. I did it another way and it worked better but I had fabric left over.

I cannot believe I never used one of these before now. This thing is a game changer super easy set up no bugs in just zip it up and forget about it

I was so relieved to find this so I could use a portable AC with my stupid crank windows. This thing is really simple to use and gets the job done. Only complaint is that the Velcro isn’t super sticky: I had to reinforce it with duct tape in several places. Not the end of the world though and still highly recommend if you need to make a portable Ac work in stupid windows

Does what it’s supposed to do, no issues at all

A+++++

This is supposed to be for a window that cranks IN. Mine cranks OUT (I have never seen windows crank in). I made it work and it works GREAT!!! You just have to remember to close the window before it rains, so the rain doesnt pool on the top.

I have crank windows(that open outwards) in my new apartment so it has been very hard to use my portable AC in my bedroom. Using this window seal has been great so that I can keep the cold air in and warm air outside during use. I did have some trouble putting it up myself though since I am short and the window is above my regular reach. I had to have someone else help me install it. No other issues so far though.

Very difficult to install and the double sided tape lasted about two hours before falling off. Dont recommend.

I purchased this for my old casement window and did the trick. Thanks

I liked the seal, seems to be efficient . The Velcro holds good make sure to clean the area before you apply the stick Velcro. It def works
