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

We only have a door in one area of our house (family room), which never allowed for us to use our portable air conditioner. Thought we would try this to allow to cool us down during the summer months. While it doesn’t fit perfectly on our door (which others reviews noted) it works perfectly!

I bought this after freezing all winter to accommodate a vent in an outward-opening casement window in my basement. Prior to buying this, the room would be FREEZING with the window cracked just enough to accommodate the 4 vent, even with blinds drawn and insulated blackout curtains. This thing is incredibly effective at keeping out the cold! The material of the seal is thin, but it can be 30°F out and my room is as warm as if the window were shut. Very impressed. Im still using the blinds and curtains for light control-- YMMV if you used it in a bare window. Havent owned it through hot temperatures yet, but so far very pleased with the purchase. Install was easy. Have not noticed any water or critters getting in, despite it being in a deep window well.

The velcro will leave a residue that is very difficult to remove. The screen does not keep temperature well and it gets very bright/hot when the sun hits it.

Product works as expected. I have a vertical window that cranks outward w a lever window latch/lock. The Velcro was easy to install and clip/work around window hardware. Velcro is sturdy and holds in place really well. For my style of window there is too much fabric to close the window and latch it closed 100% so I take the insert down each night and put it back up in about 15 seconds each morning. The double zipper is nice but seem extra at least for my style AC unit. Would buy again for a quick and inexpensive solution for portable ACs

This was very easy to install! Fits well over the screen door on my Juliet balcony. I would give 5 stars but took one off due to the fact that you can hear everythinggg happening outside and will make a loud flapping if it’s windy. Living in the city it took a little bit to get use to at night with all the noise but doesn’t bother me as much now. Other than that it does a great job keeping the cool in! The room I have it in is about 500 square feet and it easily help maintain a 68° temp no matter how hot outside!

Worked great with my AC, which I wouldnt have been able to use effectively without it.

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.

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!

I have pull in windows and I bought this to use with my portable ac to keep the cool air inside. This was really hard to install, I dont know if it was because of my windows, but it was hard to get everything ready. Then after installing it I could still feel some air coming back inside from the zippers, which I already knew would happen but still wanted to give it a chance. At the end I decided to just return it because I wanted to find a better option for my situation, but removing it was another issue. The adhesive removed the paint from my window frame, something to keep in mind if its your situation.

Purchased this because I have an odd shaped window that cranks open. There were few options for installing an air conditioner in this hot room (despite central air), so I purchased a floor model. This seems to be the easiest option for installation. I looked at the directions, its fairly common sense. Stick on the Velcro and then attach it. It attaches fine. The vinyl is thin and flaps in the breeze if you dont get it tight enough. It definitely doesnt come together like the picture unless you have a degree in engineering. It works fine and really that is all I needed. My daughter has not complained once, that in itself is a miracle. The room gets cold and I can close the window when the AC is not in use. So, 4 stars because it saved me from replacing the window for another year and it works!
