Air Lock for Portable Air Conditioner,Window Seal for Mobile Air Conditioning. Max Size 14x60 Inch

The media could not be loaded. I’m very pleased with this seal. It was so easy for me to install. Thanks for the warranty! I think it will last for quite a while although it faces the south and will get dry from the sun eventually. If it fails you promise to replace so that’s what I like too!! Increase .ml on thickness of material and product would last substantially longer

In my apartment the windows open outward like a book, and the mesh screen is on the inside. You gotta do what you gotta do. Without this product, the hot air kept blowing back in so that the portable AC wasn't as effective as it should be. I bought two of these and placed them side by side. I velcroed the border of the window, and I also used extra velcro to hold the two fabrics together down the middle of the window. I put the exhaust through one of the zippers and everything else is velcroed tight. I can see and feel the temp going down. Must have it if you have my type of windows and need to use a portable AC. Just don't forget to open the window every time you use the AC.

This was fairly easy to install. I wouldn’t say it’s very durable. But what I didn’t really think about was how bad humidity gets in Florida. Since it’s a thin vinyl like fabric, it definitely doesn’t have the ability to insulate in that it allows heat into the room and the humidity. So what’s the point?

There are not many options out there other than the fabric installed window cover. However, IT DOESN'T WORK! It was staying on until there's wind that pushes this cover in and it would fall off on it's own. No tape seems to work and without damage to keep it on other than the painter's tape. Until there's strong wind and it would fall off again. It's terrible. I wish it works. Also the seller only give returns or replacement for 30 days. That's because past 30 days it barely stays put.

It works and the Velcro is very durable. The system managed to seal up an 8” exhaust vent 97% of the way. Small areas of leakage even with cinched down zip ties but from what I could tell rain would have some trouble getting in. I used it for a crypto mining exhaust and the material could handle the heat / weight of the exhaust vent. However the fabric is pretty thin and transparent. A lot of light, and temperature can pass through pretty easily. I think it is a perfect solution in a pinch but long term I would maybe look into a more permanent product

Installation was very easy I had it installed in about 15 mintues. I was kind of apprehensive at first but once it was completely installed I was very impressed, material is very light weight but durable. I am not ready for the up in coming hot weather.

Way better keeping hot air out and dust unlock the hard plastic things that come with a ac

I cleaned the window frames & sills very well but it still will not stay adhered. Very odd to fit after trimming as well. Probably works decent with new vinyl windows.Edit: I've seen it work on newer vinyl windows and I'm moving so I'll keep it and hope for the best. The seller did offer a refund, to be fair.
