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

I think this is a very useful and innovative product. My husband was confused on how to install it at first but the videos were super helpful for him and he installed successfully. It works great to keep the heat out while using an odd shaped window for an air conditioner

Ordered this because I have Anderson casement windows and portable AC. Works great and does the job, so far.

Looks great and is really well made. It took us a minute to figure out how to tuck the end in to make it look nice but we got it. No (mosquitoes) got in so Im very very happy with that. Also received the it right on time.

Things I recommend is: - Good scissors - Measuring tape Before buying this product definitely measure you window and pick the size that matches your need. Just convert inches into centimeters. Once you do buy this product the vendor will send you couple videos showing installation and they were helpful. Having measure taping is handy so you can measure the pieces you need to cut and makes the installation easier and less likely to waste extra velcro. Keep in mind this is not perfect insulation and honestly there is no such thing but this window sealer will keep the hot air out and bugs too. After installing I just place my AC exhaust hose and use the reusable twist tie that came with this kit and lock the hose in place. Turn on the AC and my place cools down and keeps the hot air out.

Ill start off by saying I am very happy with the way this product has been performing. We have casement windows so ended up purchasing some portable air conditioners and using these window seals to make sure they didnt have to work overly hard to cool the room. So far so good. I am impressed at what a good job theyre doing. However, these are not as easy to install the first time as they make it seem. On their own website they say Install it in just seconds and that is simply not possible. I had to email back and forth with customer service a number of times even after having watched their demonstration videos. Once I got it down the first time, though, the second time WAS a lot easier. Just dont think youre going to be able to unpack this and get it set up quickly without some help.

This window seal is perfect for installing a portable AC in a crank out window. The manufacturer has some videos posted here in the questions section and on you tube to guide you step by step. Skip the printed instructions and go straight to the video. Youll have your portable AC set up and running in less than 10 minutes. The material seems very durable and provides a near air-tight seal. At the end of the season, well take it down, fold it up and store it on a shelf in the closet. For under $20, you cant beat it.

We have windows that crank outward with a screen inside, so getting our portable a/cs to be ventable had been a pain in the neck. These, while a tad challenging to ensure we understood the instructions at first, went up easily and work very well. Note that the material means no sound barriers to the outside, so if you live in a noisy place, youll hear everything as though the windows are open (which they are!), but its well worth it.

For years I have suffered in a hot bedroom because I couldnt find a way to vent a portable AC unit out of my Awning style windows. But now that I discovered Hoomee window kit, I have an AC unit in my bedroom and Im sleeping like its a cool fall evening even during the height of the summer heat! It took me less than 30 minutes to install and came with everything you need to get the job done. Its only been one season so I cant speak to its durability, but the zippers are quality. The material seems strong and the velcro is serious. Thank you for this wonderful product!

I like that it was easy to put up, however, I would of prefer d a metal insert as I am 81 and it would have been easier for me, my grand son ordered this for me, it works is all I care.

I had resigned myself to getting a swamp cooler for my room as I have a very old window (think 1920s built house), which opens in a way that looks near impossible to fit any kind A/C unit there. However, searching the internet, I saw this neat window seal and it saved me from the 90 degree weather we get in Southern California on occasion. Its really such a life saver. As for application, its a bit daunting, and I wish there were multiple manuals, video or otherwise, available for the different window types, but its easy enough with some messing around. My advice would be to make sure that youre able to fit the velcro strips in a way that will enable you to close your window still in case, since not all nights will be scorching. That and order the correct size, as I failed to do so on the first trial. Great customer service, and again, I really appreciate this product.
