Review: Great kit! - Why did you choose this product over others?: Perfect! We got the 500 one, honestly was probably a little too big for our window, but that's on us! We just tied the excess up with an elastic band. Fits really snug, apart from one small little bit near the handle. We have just a standard push out window since we live in a flat and a lot of air conditioners don't come with suitable window kits for them, so this really helped and now we can use our air con, no issues! :)
Review: Excellent and easy to install. - 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.

## 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

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.

### ⭐⭐⭐⭐ 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.
