400CM Window Seal for Mobile Air Conditioner and Tumble Dryer, EGNBU Universal Window Kit for Air Conditioner Unit, Air Exchange Guards With Zip and Hook Tape, Easy to Install

Extremely important that you buy this. We have had ours one year in and it saves our house from being too hot and gives us privacy. It’s also easy to use, durable and you only need water for adhesion . You can cut to fit and I would say it’s value for money

Probably the best sealant on the market and I’ve tried a few! Others have left their horrid sticky residue behind on my windows this has not. It’s wider than most on the market and has stayed put in the record breaking heat we’ve had this Summer. I was expecting it to melt away into nothingness when we climbed to the dizzy heights of plus 30 degrees but, to my delight,’ it stayed put. And the addition of the straps to hook the vent onto the window handle is genius!! Have repurchased ready for next year.

Got 400cm and 300cm for two windows. After reading reviews, I put down a separate double nanotape layer first before putting velcro tape on. It's not complicated to install but it is a bit of faff and you'll end up just leaving it on through summer, heatwave or not, because of effort put in to install it. It does the job well enough. My vent sits more or less on the bottom of window frame so the top part of seal doesn't have much weight dragging it down. If you have only one vent, which I assume is the case of most of us, using 3 of 4 zippers for the seal at top of vent really helps to seal the gap as much as possible and the zippers don't slide.

The durability of this is poor. After just over 1 month this has become unstuck from the window.

Perfectly sealed window. Make sure frame is clean otherwise it will come unstuck.

Does the job however peel off leaving an awful sticky residue that I had to buy something to remove from the window

I’ve been using the 400CM Window Seal for my portable air conditioner, and overall it does the job quite well. It’s fairly easy to fit – the hook tape sticks to the window frame without any drilling, and the zip around the hose is a simple but effective idea. Once installed, it does a decent job of keeping the hot air outside, which helps the room cool down faster and stay cooler for longer. It also helps stop insects and rain getting in, which is a nice bonus. The material feels okay for the price, though it’s not the most heavy-duty. At £19.19, it feels like reasonable value if you want a simple, no-fuss solution. It’s not perfect, but for the price, it’s a practical and useful addition for summer.

Excellent and easy to install. Works very well - No problems at all with installation. Make sure you clean the window frame thoroughly and take your time.

De très bonne qualité, facile à placer avec un tuto.

Pensava que por ser menor precio que otros no iba a funcionar bien, pero quede muy satisfecha por la compra, facil de instalar, trae manual en varios idiomes, buena medida que cubre casi que todo el marco de una ventanas común, parece material resitente, de momento ha pegado bien el velcro.

Génial quand on a une climatisation avec un tuyau qui sort par la fenêtre. Bravo pour le concept !

Non sapevo neanche dell'esistenza di questo prodotto, mi ci sono imbattuto per caso. Devo dire che fa ciò che promette, non ci si puo assolutamente aspettare una guarnizione ermetica, ma davvero un'ottima soluzione per chi non può modificare o rivoluzionare casa per un climatizzatore portatile "di passaggio ". I materiali sono resistenti, si adatta con facilità a quasi tutte le tipologie di finestra, anche con serramenti di ultima generazione, causando poco ingombro. il prezzo inoltre, lo trovo adeguato.

Sehr schnelle Lieferung. Passt gut. Alles bestens. Guter Kauf
