HOOMEE 157”(400CM) Universal Window Seal for Mobile Air Conditioner and Tumble Dryer – Window Kit Works with Portable AC, Easy to Install - Air Exchange Guards with Zip and Adhesive Fastener

Should have bought this years ago, easy installation and works great

I ordered this for the bedroom above the garage that is always hot during the summer. I had a portable unit from my daughter's college days but thought it would be impossible to use because I have casement windows. I had been looking at other ventless AC units on Amazon when I came upon this window seal solution. It works great! I got it in the mail on Saturday and installed it on Sunday. Easy install. 10 to 15 minutes max. Got an email message from the supplier HOOMEE asking if I needed help installing it, but I had already done it before I got the message and the link to an instruction video. The printed directions that came with the seal were very self explanatory, but it did help to see the photos other reviews had posted to see it on the window. My only issue was of my own making. I did not contact HOOMEE before I ordered a size to see how exactly to determine the size you needed. I just based it on a review I saw and looked at their window size. LOVE, LOVE, LOVE this product. A inexpensive and quick fix to use a portable AC unit with casement windows. Would recommend it without hesitation. My window still closes properly with the window seal installed and it hold my exhaust tube properly when in use or not in use. It comes with ties to attach the hose to the zippers of the seal to make sure it all stays together and secure. Best $ I think I have ever spent to make my home more comfortable for guests using that bedroom.

This is a great idea with an interesting implementation, and with a few minor alterations to the design it would be perfect. As it is, it does a great job. First, the Velcro sides should be flipped. They send a roll of prickly side for the sticker for your window and have the soft side sewn in. While trying to run your finger over the Velcro you stick on your window frame, it is going to hurt, but if they made the soft side the side that was stuck on the window, there wouldn’t be that problem. Second, the ordering instructions say to order the closest rounded number to your window perimeter, but that will leave a small crack if your window is slightly larger than the size, so if your window perimeter is over 400cm, get the 500cm. As it sits, the edge that follows along the physical window has spots that bunch up. Which leads me to my last complaint, 100cm is WAY too big for that to be the size difference options. I needed a 425 or 450, as my window perimeter was 416cm, but getting the 500cm would have been crazy. But now I have a small section of my casement that leaks the hot air back in. I will have to make a small two sided strip to fit the difference. Over all though, this is a great solution to this problem. My summer will be nice and cool because of this product!

This worked AMAZING for my apartment window. It was pretty easy to install, and kept the heat out. One of the zippers did break but I was still able to use it. HOWEVER, do keep in mind that the glue residue will be extremely hard to get off. When I moved out recently, I had to use a vinegar/water solution AND my hair dryer to get it off. Get ready to scrape!

I have crank windows that open outward. This worked just fine on mine. All that I had to do was reverse the instructions. Worked great keeping the heat out and the cool in during the summer very easy to install, only about 15mins or so. The velcro is small enough as to not stick out when the adapter isn't in use. It didn't rip when I moved it along the window when I installed it. Seemed pretty thick, probably well enough made to be used for multiple years to come. The zipper being double ended gave enough for the vent and the drain tubing to go out the window. Great for use in a home that only needs a portable AC occasionally.

This may be a decent product but it just wouldn’t work on my casement window which opens outward. Velcro strips need to be attached to the outside of the window frame. My metal frame doesn’t have any smooth surfaces on some sides and a smooth but extremely narrow surface on other sides. Using masking tape, duct tape, cardboard, weather stripping, and the factory installation panel, I fashioned an effective enclosure for the Midea dual hose AC.

It was very straight forward to install. We are in an old building so the windows are single paned. I couldn’t find a seal kit that was the exact size so I sized up and tucked in the ends. Works really well and is much better than a blanket tucked into the window. Just read the instructions carefully to get it right.

Ok, yes it took me over an hour to install and I’m glad I didn’t rush it, turned out perfect. I have a portable a/c in the living room of our condo but was never able to use it in the bedroom do to the window being outward facing, no way to vent the hot air out and close off the rest of the window. Just bought a dual hose a/c from the neighbor who is moving (75 bucks, nice!) and found this kit on amazon. It actually installs, functions and finishes better than the description and pictures. Cold enough to need an extra blanket in July, love it. Now I’m on a hunt to find another deal on a dual hose a/c to replace our single hose a/c in the living room. Absolutely no comparison no matter what btu rating the single hose unit is, mine is 14000. Never buy a single hose a/c!

Lätt att sätta upp och verkar vara hyfsad kvalité samt bra pris.

The installation took a bit of time, but with watching the YouYube video and one of the clips left in the reviews, I managed to get it right almost straightaway. The only tip I'd pass on would be to make sure you don't attach the corners to the velcro too tightly, cause it will make it harder to open and close the window. I only attached it to three sides of the window, as the fourth side is airtight so I didn't want any faff with extra material. My window opens both ways (kiep-kantel for Dutchies) and the seal works pretty well. I can only use it one way now, but that's fine. If I want to close the window I have to make sure the zipper doesn't get stuck at the top, but I can still close it which is all I need really. I tested it with my aircon and it's great, barely any outside air gets in.

I bought the HOOMEE 400 CM Universal Window Seal for my portable air conditioner, and I am very satisfied with the purchase. The quality of the product is excellent, and it comes very well sealed. The installation instructions are clear and detailed, making the installation quick and easy, even on my window that opens from the bottom. The package includes all the necessary accessories for installation. However, as a recommendation, it would be helpful to include something to tie up the excess parts if the window is shorter. Other than that, the product works perfectly and has significantly improved the efficiency of my air conditioner. I would definitely recommend it for its excellent quality-price ratio.

We got air conditioning unit last year but having the window open for the tube when it was 30+ degrees outside meant it still never really for cold enough. This easy to install seal makes a huge difference and I’m really impressed by it. The seal is simple to attach and just requires you to add the Velcro to the window frame and attach the seal. Once attached there’s four zips so you can have the pipe through one hole and still be able to open the other zips to get to the window handle when you need to. You can also cable tie the zips round the tube so it doesn’t come open. The seal doesn’t keep out 100% of the heat but it keeps out enough to make a difference. If you don’t want it attached during the winter months you can just pull the seal off and leave the Velcro up ready to use again next year. At £20.99 (it’s current price) I think this is well worth the money and I’d definitely recommend it.

Just received and installed this so I may have to add to this later. As always I'm impressed with the delivery time. Ordered at about 10:00 am and it was delivered about 7:00 pm. Installation was relatively easy although the directions are not all that clear (ie. not clear which is the narrow and the wide side of the cloth insert). In my case the lock and the handle of the window prevented a complete strip of Velcro along the window side. However by adjusting the insert tightly over the handle and the lock I was able to make it airtight. It seems to allow the air conditioner to work properly without any air leakage. All in all I am quite pleased with this as it is much simpler than the plexi glass system I used in the past. And the price is right. Lastly there is some excess material left at the bottom of the window which would be unsightly if I ever had the curtains open. I recommend this product.
