HOOMEE 400CM Universal Window Seal for Portable Air Conditioner And Tumble Dryer – Works with Every Mobile Air-Conditioning Unit, Easy to Install - Air Exchange Guards With Zip and Hook Tape

As you can see in the photo, I have a rather annoying casement style window in my living room that opens outwards. Unfortunately I get very little cross-ventilation in my apartment, so when the outside temperatures rise above 24-25 Celsius (75F+), my flat feels like an oven (the temperature gauge on my heater thermostat shows 29C and can go up to 35C on really hot days). The remedy? A portable air conditioner!My living room is 24 feet long by 15 feet deep, so around 360 square feet in size - hence I got a 12,000 BTU rated unit as these are able to easily cool up to around 450 square feet of space. I had done a fair bit of research online and found that most people who rate these portable units poorly seem to install them incorrectly (usually by not properly sealing the window). And yes, they are a bit noisy - but let me tell you - it's worth it! Today while the temperature gauge was showing 27C in my bedroom, my living room was a chilly 20 degrees! A huge difference in feel!This window seal is a pivotal part of the equation. Know that it will fit virtually any window type (including mine, which was not listed, but which I deduced from photos and videos that I saw online), so long as you measure the perimeter correctly and order the right size! Make sure you order the closest size to the perimeter! The only tools you need to complete the installation is a pair of scissors. Follow the instructions carefully (they were pretty clear), and if you get confused, there's a video on YouTube that can be helpful (but it's not rocket science). It took me about 8 to 10 minutes to install the seal.Some thoughts: While the sticky part and Velcro strips on the seal are quite strong / top notch (I stuck mine onto the glass part of my window as the frame had locks in the way, and it sealed flawlessly), I do wish the overall fabric material of the seal was a bit thicker. The reason for this is the material is so thin that I can clearly hear the hose venting the hot air outside the window, and that just adds to the noise factor. HOOMEE - perhaps this is something you can address in a future version of the product? A thicker, more insulating 'Quiet' material? I would gladly pay more for it. But perhaps I'm nitpicking - it works, and it's worth it's weight in gold for me!

Just bought a portable air con unit so needed one of these so I could vent the air hose out of the window but keep the room cool. My window's total exterior rim measurement came to 380 cm so I ordered the 400cm version.The item arrived same day, thanks to Amazon Prime. I found fitting relatively easy. The velcro tape has extremely strong adhesive - be careful not to stick it to your fingers. But because my window swings open from the bottom and has hinges on either side edges, rather than along the top, it has a large gap at the top when it is open. This means that the designed taper of the fabric strip only just overlaps at the top and there is limited spare material for making gussets at the window corners. I proably should have ordered the next size up. But it does seem to work well and the room cools down quickly.

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.

Product works but looks unsightly will only keep up whilst the weather is hot then remove which is a shame as I would like it to be a permanent fixture. Unfortunately its the only way for the types of windows we have and I don't want to put a big hole in out brickwork. You have to band the excess fabric which again looks messy hopefully some one will come up with a classier design in the future. Strong fabric though will see how long it lasts over time.

I bought one of these seals to enable our portable air con to work without cooling the entire country side and I bought another one for an upstairs bedroom.The instructions are good and especially useful as I have windows that open outwards which is covered in the instructions.I fitted this in 10 minutes being careful to clean the surfaces and cut to size accurately and after putting the seal on the wrong way I got this sorted out and it works great. The white self adhesive Velcro is almost invisible.Good product.

After struggling to find a cover for my particular window I gave up and bought this one. Mine is a long thin horizontal window and while it doesn't fit perfectly it does the job good enough. Installation took a little while because I had to get my head around how to best fit it to the window but I haven't had any issues arising since. Once I worked it out it was easy to install.

Fantastic - just what we needed.We have a window that opens out like a book, and for some reason we found it a bit difficult to conceptualise how the whole thing went on. The quick instructions, in case anyone else finds themselves in this sitatuation:1. Put velcro tape on the window frame2. Put velcro tape on the window itself. We did both of these with the window closed so we knew it wouldn't impede. There is a small gap where the window handle is.3. Fold the seal in half to find the middle. Start this middle of the frame by your window handle, and then go around. Connect other side to the window itself. We have some floppy bits on the side of the window that barely opens. We just tucked them in and around until it was relatively sealed.4. Feel smug, and dumb for not realising before that it's so straightforward.It works well enough that the seal gets sucked in and creates some pressure. We noticed the air con unit worked much more efficiently when it was properly sealed off as opposed to my temporary fix. We will definitely save the money in energy for the cost of the seal in no time, and it also doesn't look as trashy as a cobbled together collection of window blocking things!

Yeah fair play, I've had this for a bit now and it does exactly what it says on the tin. Took about ten minutes to install and it's not budged in a whole month's worth of opening/closing the window. Happy enough with that much use out of it for the price. Makes even our rubbish cheapo AC more effective by a few degrees, so really happy. Wouldn't think twice about re-ordering.

fit perfectly. would buy again.

Way better than the crappy diy foam board I had up before. Was easy to install and so far seems good. I taped it a bit as my dog doesn’t like the flapping sound it makes from the wind so I taped the excess part down but it wouldn’t have needed any extra tape otherwise. Very happy!

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

ik ben zeer tevreden

Macht was es soll, man muss aber etwas tricksen mit Klebeband weil es natürlich alles etwas fummelig ist und vorallem zwischen den reißverschlüssen noch Luft reingezogen wird. Wir sind aber sehr zufrieden damit und sind froh über den Kauf.
