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)

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

I have crank windows in my house and I absolutely hate them, but theres no changing the windows. It doesnt get hot save for a handful of days through the year so nobody has A/C. We got an A/C unit and also got this for the vent out the window. It was NOT easy to get the Velcro on there. It also was damaging to the pain around the window because the glue on the Velcro is no joke strong. The strength of that Velcro is worthy of a star. Once I had the Velcro I attached the seal and the A/C unit vent attached. It was a pretty big disappointment. Having the window open with this shield attached just let ALL the heat in letting any cool air the A/C unit produced go out. Maybe my window is just too big but it was much smaller than the dimensions of this seal. The material of this is just too thin and would be better if it had some insulation to it.

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

Good product and fast delivery.

Other than the cheap glue to hold the velcro onto the window this product works well and is very easy to install. My house was built in 1961 and almost all the windows are original and kind of a weird design but I had no problem with the install. However, where the AC hose vents out the velcro popped off from the weight. The glue really doesnt hold up all that well. Otherwise a useful product which pretty much solved my AC dilemma.

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.

Applying the seal was a nice and smooth process, however, the zip ties to keep it closed are too short to wrap around your exhaust tube. Not only that, the zipper is too small to loop it through.

This is just what I needed for my single hose portable A/C (though I see it can accommodate two hoses if needed. It is a bit odd to contemplate and visualize at first (I thought), and the illustration with the directions I found bizarre, but the product itself is a great quality and very logical in how it attaches to my window. As the circumference did not quite reach all the way around my window (I did not want a larger size with a lot of gathering to contend with), so I just purchased white painters tape to complete the last 6 near the window hinge area and that seems to work great. Do pay attention and measure your windows.

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

I got one of those Dalek air conditioners, but it had no venting tubing and the plastic hose connector was broken. Epoxy and new parts made it work, but it was a trick to vent it out a tiny pantry window. I really expected this kit to be a mess to work with, but it was easy. It doesnt stay put quite as well as I had hoped, but that may be because it was hard to get rid of all the kitchen grease at the edges of the window frame.
