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

Used this product on our roll-out window along with a new portable AC unit to keep our upstairs sons room cool during the on-going heatwave this summer. It works great and it took less than 20 minutes to install. Seller follows up with helpful tips to make sure the window seal is working as intended...wonderful customer service!

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 purchased this product with my fingers crossed it would work in a portable AC exhaust hose application in my travel trailer/toy hauler. As with most toy haulers there is a horizontal type casement window in garage area that opens from the bottom. This product was very easy to install with very simple slight modifications made in the latching area. It performs perfectly!! I’m even able to close the window when not in use without having to remove the product. For the price I am completely blown away how effective it is. I would highly recommend to anyone!!!

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!

Allows me to use an air conditioner in an unusual window and still close the window when not in use.

Seller very good customer service. Provided contact of needed prior to product arrival. Watch the you tube to install. Very helpful! Pretty easy once you line it up. Works as advertised. Used all season never had to remove. Pretty good even when exposed to weather.

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 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.

I was so excited to receive this as our bedroom gets hot and we have a crank window. It was okay to install, didn’t give a tight seal because of how are window was idk? It lasted a good month before it fell down, in ND, it gets hot AF, and humid, the stickiness of the Velcro came off and I gave up
