HOOMEE 300CM 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

Purchased to use with a portable air con unit. My windows all 4 sides using window frame surround as my measurement was 286cm so I purchased the 300cm(3mtr) hoomee. This was more than enough. Instructions were clear but the basics are cut double sided Velcro to fit around window surround then as my windows open out attach double sided Velcro on inside of window frame. Then attach the hoomee sheet as per instructions making sure you start at your window handle by middling the sheet and simply attach to Velcro.Positivesgood adhesion to window frame, hoomee sheet is strong and well made and Velcro is good quality. Allows you to habe this fitted all year round as window will close when fitted.NegativesAll I can say is having a sheet round your window isn't the prettiest but you can detach the sheet from the velcro if preferred but as I haven't I won't comment on how good fixing and unfixing may affect the adhesion but will say I don't think there would be any loss.

Updated my review following a fantastic experience with customer services. They were extremely helpful and quickly identified that the information on the listing wasn't accurate for my type of side opening window and also sent a video to show the quickest way to fit it. They quickly arranged a replacement which has been fitted and seals all 4 sides completely. Only issue is the zips are a little lose so the hose sometimes comes lose but have wrapped a towel around mine to keep it in place. Does the job nicely and reduces heat from the hose coming back into the room. For the price it's really good and the fabric and velcro is very strong and unlikely to rip like some cheaper versions I've seen.Looks a mess, doesn't really fit properly but does seem to help with the heat generated. Don't think it's really designed for a side opening window. Didn't understand why you only measured 3 sides when it sticks to all 4 either.

Bought this to replace the piece of cardboard jammed in the window. I wasnt too sure how effective this was going to be to stop the heat from coming back in and to stop insects invading the bedroom. I watched the installation video a couple of times as my window opens outward. I applied the velcro to the window surround and window frame, to be honest there was a bit of material left over but I secured this with a clothes peg to close the gap. The material is strong as are the zips, the velcro provides a strong seal to the window frame and once you get the hang of zipping up the aircon hose and locking it with the reusable cable tie this really is a bit of effective kit. I have used this all summer and now the weather is cooling I can leave it in place and still close my window. For the money you really cant go wrong and the after sales support is also excellent with follow up emails to check if all is ok and offer of support for installation questions. I would highly recommend it.

The product itself is well made and does the job so would have been 5 stars if it was as simple to install as advertised. However I cannot give it more than 3 stars due to the unclear instructions and the difficulty in installing it around the fittings of my window.Firstly, the velcro really sticks and WILL take the paint of your window and frames, so you need to stick it in the right place first time. However, this is tricky because unless your window is exactly the same as that shown in the product's idealised pictures it's not obvious until you get it fitted exactly where you need the velcro. Anything about your window that is slightly different to the ideal version shown in the advertisement will distort the path that the velcro needs to follow. For example, my window has a closer and a large handle and locking mechanism so it took some experimenting to find the right position for the velcro.So in my case I followed the instructions (which are really poor by the way - you'll need to watch their Youtube video which is much clearer) and stuck the velcro first, but as the top and bottom (sill) of my casement are horizontal (not vertical like the instructions assume) the cover has to twist through 90 degrees in two directions at each corner which distorts everything as well. When I tried to reposition the velcro to adjust the fit then the paint was pulled off in large patches.My recommendation is to use bluetack or something to stick everything in place temporarily whilst you adjust and make sure everything is in the best position, BEFORE taking off the backing paper and sticking down the velcro permanently.

It is extremely easy to install. Trick is to watch the videos relevant to your window, then watch them again! Assuming you've ordered the correct size, once the Velcro is on the window and the frame, if you do put it on the wrong way (yes you can!) simply pull it of and correct your mistake.As my new air con arrived a few days before I got this, I simply stuck the hose out of the bedroom window. It worked OKish, but what a difference it made after installing this! The room cools down significantly quicker and you can feel the air resistance when you open or close the bedroom door with the air con going.We've had two follow up emails since we bought this asking us to contact the supplier if we had an installation problem (not enough Velcro etc) and they would sort t out for us. Not needed thankfully but a reassuring touch.Shane I couldn't give them more than 5!!

Fairly easy to install if you watch a tutorial on YouTube first. I would say it went well for me but still ended up having excess folds which creates small gaps for bugs, etc to possibly enter. Good quality material, I can see it surviving a long time with daily use.

Avoid this company product failed after 3 months and they will not send out replacement tape.

Got this for a side opening windows for me ecoflow wave 2, works absolutely perfect. Not much in the way of insulation but can cool a 10m2 room down to 18deg C no sweat. I kept the curtain close to help
