AC Window Seal,Portable Universal Window Kit for Mobile Air Conditioner Unit and Tumble Dryer 400cm/158Inch,Hot Air Stop Air Exchange Guards with Zip and Adhesive Fastener

Bought this summer as the window seal that came with my AC didn’t fit. Easy to apply, and the white velcro blends in nicely. Added a shoelace to tie the zippers as a precaution with my cat. Without this seal, the AC barely worked — after adding it, the room felt much cooler, so it clearly keeps the hot air out.

Seems to work ok. Does it provide an airtight seal? No. Does it need to? No. Does it keep insects out? Yes. Are the instructions clear? No. Do you need them? Not really. Stick the tape around the window. Stick the tape around the frame. Attach the material to both - make sure the thickest bit of material is in the middle of the widest gap. Undo the zip, stick the pipe through and do up the zip, use the cable clips to keep it done up. That's all it needs really.

Great kit that gives you everything for a decently sized window. Makes a good seal and is easy enough to put up and take down each time you want to use it.

The Bottom Line: If you are looking for an affordable way to boost your portable AC’s efficiency, this 400cm universal seal does the job. It effectively stops the "backflow" of hot air, making a noticeable difference in room temperature. However, be prepared to supplement the included adhesive if you plan to open and close your window frequently. The Pros: Performance & Fit Effective Cooling: Once installed, the difference is immediate. It creates a solid barrier that prevents hot exhaust and humidity from leaking back into the room. Universal Versatility: At 400cm, it’s long enough for most standard casement or tilt windows. The zip system is clever and accommodates almost any hose diameter without gaps. Energy Efficient: My AC unit doesn't have to work nearly as hard to maintain a cool temperature, which should help with the electric bill. The Cons: Durability & Versatility Weak Adhesive: This is the main drawback. The provided adhesive tape struggles with tension. If you live in a particularly humid climate or have a heavy hose, the "sticky" factor wears off quickly. Lack of Customisation: It’s a "one size fits most" design, which means if your window is significantly smaller than 400cm, you end up with excess fabric that can look a bit messy or "baggy" on the frame. Difficulty with Window Operation: Because the glue isn't incredibly strong, the tugging and pulling required to open or close the window often causes the seal to peel away from the frame. It’s best suited for a window you plan to leave shut for the summer. Expert Tip for Buyers: To make this product truly "permanent" for the season, I highly recommend buying a roll of heavy-duty industrial Velcro or double-sided mounting tape. The fabric seal itself is high quality; it’s just the included glue that lets it down. Replacing the stock tape makes the whole setup much more stable when you need to adjust the window.

We have only been using it this summer but it was easy to fit, easy to use and works well. Someone has obviously thought about the practicalities of using it as you can open the zip in two places so you can zip up around your hose and also open the zip in a seperate place to use your window handle to open/close the window. You can easily close your window without having to remove the seal as it just folds up as you close the window although it your that bothered it only attached with velcro so you can remove it if you think it looks bad. Reading reviews for multiple products i did see a regular issue with all these kits which we have encountered which is near the hot air exhaust the sticky parts seem to detach occasionaly but we this only seems to happen if you have it taught and they have always just stuck back on for us at the moment. Whether this works long term.i.e. we can reuse it next year we will have to see but it seems fine at the moment.

Just to add an update: it has been several days since installed and have definitely noticed a difference in A/C ability to cool room. Also, it has remained in place since installation which I initially was concerned about. Although instructions are difficult to understand, it is cleaning of the window frame which would seem to me to be the more most important thing, otherwise it will not stay up! This took me a lot of time to do, as did sticking the Velcro correctly to the window frame so that it would not pull away with the weight of the A/C hose. Otherwise, it is okay and hasn’t come down yet, considering this week was very hot days and nights. So, the take home message from me is to clean your window very carefully, take time to get Velcro to adhere well, pressing it into place with a tea towel works well and to support the weight of the hose on the window sill with something like a couple of books to take the weight of the hose of the installation. It doesn’t look pretty but this isn’t a beauty contest.

Brilliant! Excellent value for money. Due to the front facing vents this will cool the whole floor of a small house if you leave the doors open. Relatively quiet and small design. I wish I had bought this first time around instead of a pricey alternative

Schnelle Lieferung. Die Ware ist ordentlich verpackt mit lesbarer und verwendbarer Beschreibung geliefert worden. Das Klebeband ist von guter Qualität und war einfach am Fensterrahmen anzubringen. Das Band hält gut. Der Plastiksack hat sich gut anbringen lassen. Er ist seit 2 Tagen in Dauernutzung. Es hat sich bisher nichts gelöst. Eine klare Kaufempfehlung von mir 👍🏻
