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

Even ordering the wrong product. I was able to adapt it to fit my window. Have only used 1 day and works fine. Company emailed me next day. Very pleased

I like that it actually works! Once I figured out how to install it properly...it took a couple tries but managed in a about an hour to finally do it right. Watch the video a couple time helped!

At first he didnt want it, but we keep insisting. Putting it together in a hot room is awful puts me in a bad mood. No ones talks to me when Im tinkering. But now hes glad to have AC in that weird crank window, lol. After I got the right window kit & portable AC it was easy.

It took me less than an hour to install this window kit and so far, I’m extremely pleased with it. I recommend taking the time to measure & cut your adhesive strips with the window closed so that you’re sure you can close the window after the plastic is on, and to ensure a tight seal.

This is my second time purchasing from this company and they do not disappoint. Just make sure to measure your window correctly and you shouldn’t have a problem with putting and installing these into your window. Also take a note about where you want to put your Velcro, as removing it can strip the paint from your trim so you wanna do it correctly the first time. However I’ve had many a person comment on the ingenuity for the roll out windows in my area and I don’t have to suffer the summer months.

Not only is this product great, but their customer service is fantastic! The install was easy and the company reached out to me before and after delivery to make sure that everything is good. Finding customer service like this is rare to say the least. They are fantastic!!!

I have an outward opening window. It is old and was not properly painted when it was installed. I had to adjust how I attached the Velcro to the frame due to the paint issues and all the crazy little trim accents that arent wide enough for the Velcro. But, it has worked great. There have been several bad rainstorms and only a tiny little bit of water has made it in. And that water stayed in the window opening. I did not close the window for any of the storms. Im impressed with the ease of installation and quality so far. Ive had it installed for 3 weeks now.

I have regular, sliding windows. But the windows are tall. The window kit that came with my portable Frigidaire a/c wasnt tall enough to cover the entire window opening. After looking and looking, I nearly gave up and was about to spend hundreds of dollars to ask a professional to come solve this for me. And then I found this product. Decided to try it given the 5-star reviews and low price, and voila! It worked better than the standard window kit. Its now been a week, and my a/c is working exceptionally well. The cloth is plastic, and is air-tight. Fits nearly any kind of window. Buy this before you lose hope on how to install your window kit for your a/c. Installation time for me took a little longer than most (~30 mins), since the shape of this is not a rectangle, but my window opening was (regular sliding window). I just let the cloth hang a bit where there was extra. Worked out fine and the seal is still holding. Would HIGHLY reocmmend

The air conditioning in my upstairs bedroom has not worked for years. Unfortunately there is no window in the room only French doors so I could not get a window air-conditioner. I am not crafty or handy in any way so rigging something with the French doors was out and I did not want to spend thousands on a ductless air-conditioner. I stumbled on this product and thought I should give this a try. It was easy enough to install. I had to get some extra velcro bc I put it in the wrong place on the door frame but once I figured it out it was simple and only took like 30 minutes to get the whole think up. The hose fit in the zipper hole and I used the zip ties to keep it in place and used some ductape to really seal it all the way. All in all this product was a cheap way to make an otherwise very uncomfortable room livable. I would definitely recommend getting this product. I also watched the YouTube videos in the question section and they were very helpful.

The original window seal that came with the air conditioner I had wasnt waterproof so water came into the seal when it was raining. When I ordered a new one to replace it I picked this because I saw that on the description that this seal is waterproof. When I asked for help for the correct size for my specific window, the seller gave me a quick response and the 400cm window seal they recommended fit my window perfectly. Even the small crack is sealed and there is no hot air or rain coming into the room now. Easy to open and close window, easy to install and a really creative solution. I would recommend this if you have similar issues!
