Review: Buy this , it’s amazing - 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
Review: Stays put and does the job! - 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.

## Features

- No hot air incomes: EGNBU air conditioner window seal keeps the warm air out of the hose of your portable air conditioner by locking the hose between the window frame and window housing. Our window seal keeps insects, mosquitoes, rain out and creates a "closed environment" that keeps your room cooler for longer
- INCREASE COOLING PERFORMANCE：Enjoy a cooler environment in summer thanks to EGNBU! EGNBU window seal air conditioner around your window and then zips around the nozzle of your hose and blocks the return flow of warm air, so that your mobile air conditioner is more efficient and your room cools in less time
- REDUCE ENERGY CONSUMPTION：EGNBU loves the Earth. This window seal helps to reduce energy consumption and reduce carbon dioxide emissions, which is particularly high in summer due to the massive use of air conditioners. EGNBU window seal for air conditioners prevents warm air from circulating in your room and saves you on electricity bills
- Easy to install: no need for drilling holes. No need for window kits, everything you need comes with your EGNBU window seal! Simply apply the adhesive hook tape to your window frame and to the window bag. Attach the window seal to the hook tape. Then open the zip on the window seal and put your air conditioning hose out of the window. At the end, close the zip tightly around the hose
- Universal: suitable for all portable air conditioners and tumble dryers. Whether for windows that open to the left, or for windows that open to the right, windows hanging down or skylights, EGNBU Window Seal will do the job. It fits a window with a maximum circumference of 400 cm

### ⭐⭐⭐⭐ Good enough. Put aside some time and energy to put them up.
*by K***A on 25 June 2026*

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.
