Airlock | Window Seal For Portable Air Conditioner, Flexible Size, Max 14x36 Inch.

I have 2 portable air conditioners that have a problem every summer with hot air from hose and outdoors leaking in. I found these products by accident on Amazon and figured I'd give them a try, anything would be better than the hard plastic vents which came with the units that are difficult to use. These were so EASY to install and really work so well, no air getting in and air from unit being directed out. I also can quickly take air hose out of window if it's raining too hard and reinstall in seconds when needed. Window is not damaged in any way and can always get more Velcro tape if needed but since I have installed them I have had no problem with them coming loose at all. Highly recommend this product!

If this was a little thicker, had stronger adhesive on the Velcro tape, and didn't leave gaps around the exhaust pipes, this would be a solid 5 stars. As it is, I'd give it 3.5.As you can see from the monstrosity I've constructed, it needed a lot of modifying to work for me. I don't have an air conditioner (god I wish), but wanted a way to vent the heat in my bedroom room outdoors with a fan without having my window open all the time. I'm just using a cheap fan and a dryer exhaust duct cut to size. To solve the gap issue, I just taped cheesecloth over the gaps on the side that faces out, which I might replace with really strong tape if that lets in too much heat in the summer. As you can see I had to tape the whole thing to the window because the Velcro tape kept coming off as I was making adjustments (I did give it some time to "cure" but its just really not sticky). And again, I wish the material were thicker and more opaque because the sunlight in the afternoon heats the room up and I obviously can't close my blinds. I also have some concerns about durability due to sunlight and heat deteriorating plastic, but we'll see.Overall, I'm satisfied for the price and the modifications weren't very difficult or expensive. It sure is ugly, though!

I am really pleased with the product and the whole experience of buying from this seller. I was concerned at first that it wouldn’t work for me as my AC unit has 2 hoses. However this was not an issue and it worked with no issues and better than I would have ever expected. I’ve noticed a massive difference in the time it takes to cool the house down and would highly recommend this product to everyone especially those struggling with the summer heat like us

Not a perfect fit for my small window but it works! Easy installation and fast delivery. I love this product!

Product was much smaller then described.

This was so so easy to install! I had it up in under 15 mins. My ac is working great now. It is far better than the piece that came with my ac. I was constantly having to tweak my old thing. I would recommend this to anyone!

This product actually worked out nicely. My only complaint is that it did not seal completely around the hose even with the use of the zip ties. I used tape to seal. So overall not a bad buy at a reasonable price.

It's made to be velcro'd on all four edges, but it's about 36" wide exactly, not leaving room to velcro to the edges of the window. It should ideally be another inch wider to actually overlap the window trim to reach where the velcro would be adhered. I ended up just putting the velcro on the top and bottom because of this
