157”(400CM) Universal Window Seal for Mobile Air Conditioner and Tumble Dryer – Window Kit Works with Portable AC, Easy to Install - Air Exchange Guards with Zip and Adhesive Fastener

I have crank windows that open outward. This worked just fine on mine. All that I had to do was reverse the instructions. Worked great keeping the heat out and the cool in during the summer very easy to install, only about 15mins or so. The velcro is small enough as to not stick out when the adapter isn't in use. It didn't rip when I moved it along the window when I installed it. Seemed pretty thick, probably well enough made to be used for multiple years to come. The zipper being double ended gave enough for the vent and the drain tubing to go out the window. Great for use in a home that only needs a portable AC occasionally.

I ordered this for the bedroom above the garage that is always hot during the summer. I had a portable unit from my daughter's college days but thought it would be impossible to use because I have casement windows. I had been looking at other ventless AC units on Amazon when I came upon this window seal solution. It works great! I got it in the mail on Saturday and installed it on Sunday. Easy install. 10 to 15 minutes max. Got an email message from the supplier HOOMEE asking if I needed help installing it, but I had already done it before I got the message and the link to an instruction video. The printed directions that came with the seal were very self explanatory, but it did help to see the photos other reviews had posted to see it on the window. My only issue was of my own making. I did not contact HOOMEE before I ordered a size to see how exactly to determine the size you needed. I just based it on a review I saw and looked at their window size. LOVE, LOVE, LOVE this product. A inexpensive and quick fix to use a portable AC unit with casement windows. Would recommend it without hesitation. My window still closes properly with the window seal installed and it hold my exhaust tube properly when in use or not in use. It comes with ties to attach the hose to the zippers of the seal to make sure it all stays together and secure. Best $ I think I have ever spent to make my home more comfortable for guests using that bedroom.

Purchased this because I have an odd shaped window that cranks open. There were few options for installing an air conditioner in this hot room (despite central air), so I purchased a floor model. This seems to be the easiest option for installation. I looked at the directions, it's fairly common sense. Stick on the Velcro and then attach it. It attaches fine. The vinyl is thin and flaps in the breeze if you don't get it tight enough. It definitely doesn't come together like the picture unless you have a degree in engineering. It works fine and really that is all I needed. My daughter has not complained once, that in itself is a miracle. The room gets cold and I can close the window when the AC is not in use. So, 4 stars because it saved me from replacing the window for another year and it works!

Should have bought this years ago, easy installation and works great

This worked AMAZING for my apartment window. It was pretty easy to install, and kept the heat out. One of the zippers did break but I was still able to use it. HOWEVER, do keep in mind that the glue residue will be extremely hard to get off. When I moved out recently, I had to use a vinegar/water solution AND my hair dryer to get it off. Get ready to scrape!

Doesn't work. It doesn't stay attached, the velcro tape doesn't keep it sealed, after 1 day it gave out and had big holes letting the hot air in the house.

Although I put the tape on the wrong side of the stationary farm, it works quite well with my antiquated cantilever window. Although opaque it still allows a sufficient amount of light to prevent my room from feeling like a medieval dungeon or subterranean cave.

fit perfectly. would buy again.

Way better than the crappy diy foam board I had up before. Was easy to install and so far seems good. I taped it a bit as my dog doesn’t like the flapping sound it makes from the wind so I taped the excess part down but it wouldn’t have needed any extra tape otherwise. Very happy!

Lätt att sätta upp och verkar vara hyfsad kvalité samt bra pris.

The installation took a bit of time, but with watching the YouYube video and one of the clips left in the reviews, I managed to get it right almost straightaway. The only tip I'd pass on would be to make sure you don't attach the corners to the velcro too tightly, cause it will make it harder to open and close the window. I only attached it to three sides of the window, as the fourth side is airtight so I didn't want any faff with extra material. My window opens both ways (kiep-kantel for Dutchies) and the seal works pretty well. I can only use it one way now, but that's fine. If I want to close the window I have to make sure the zipper doesn't get stuck at the top, but I can still close it which is all I need really. I tested it with my aircon and it's great, barely any outside air gets in.

As you can see in the photo, I have a rather annoying casement style window in my living room that opens outwards. Unfortunately I get very little cross-ventilation in my apartment, so when the outside temperatures rise above 24-25 Celsius (75F+), my flat feels like an oven (the temperature gauge on my heater thermostat shows 29C and can go up to 35C on really hot days). The remedy? A portable air conditioner!My living room is 24 feet long by 15 feet deep, so around 360 square feet in size - hence I got a 12,000 BTU rated unit as these are able to easily cool up to around 450 square feet of space. I had done a fair bit of research online and found that most people who rate these portable units poorly seem to install them incorrectly (usually by not properly sealing the window). And yes, they are a bit noisy - but let me tell you - it's worth it! Today while the temperature gauge was showing 27C in my bedroom, my living room was a chilly 20 degrees! A huge difference in feel!This window seal is a pivotal part of the equation. Know that it will fit virtually any window type (including mine, which was not listed, but which I deduced from photos and videos that I saw online), so long as you measure the perimeter correctly and order the right size! Make sure you order the closest size to the perimeter! The only tools you need to complete the installation is a pair of scissors. Follow the instructions carefully (they were pretty clear), and if you get confused, there's a video on YouTube that can be helpful (but it's not rocket science). It took me about 8 to 10 minutes to install the seal.Some thoughts: While the sticky part and Velcro strips on the seal are quite strong / top notch (I stuck mine onto the glass part of my window as the frame had locks in the way, and it sealed flawlessly), I do wish the overall fabric material of the seal was a bit thicker. The reason for this is the material is so thin that I can clearly hear the hose venting the hot air outside the window, and that just adds to the noise factor. HOOMEE - perhaps this is something you can address in a future version of the product? A thicker, more insulating 'Quiet' material? I would gladly pay more for it. But perhaps I'm nitpicking - it works, and it's worth it's weight in gold for me!

Die Fensterabdichtung erfüllt ihren Zweck sehr gut. Montage geht schnell, alles sitzt dicht und warme Luft bleibt draußen. Das Klimagerät arbeitet dadurch deutlich effektiver. Lässt sich sauber anbringen und bei Bedarf wieder abnehmen. Absolut empfehlenswert.
