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)

A+++++

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

Product does what it says , BUT the adhesive strips that hold it together are horrible and keep falling apart.

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.

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

Its definitely easy to install and an economical product to fix the window issue with portable ACs, but the drawback is that it will not stop the hot air coming inside the room. Once the AC is turned ON its difficult to check if its really closing the gap and blocking the hot air seeping in, but take off the portable AC unit and close the zips properly leaving the window on a cold night. Your room will be lot cooler than the remaining part of the house.

This was perfect for our window and portable AC. Now unfortunately my window was not exactly like the one in the picture and can open in a way that is split but I found a way to Jerri rig this to fit my needs perfectly.

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.

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