About this item

  • NO MORE HOT AIR INCOMES – HOOMEE window seal keeps the warm air coming from the hose of your portable air conditioner away by locking the hose between the window frame and the window itself. Our window seal leaves out unwanted guests, rain and crates a “closed environment” that keeps your room cool for longer.
  • INCREASE COOLING PERFORMANCE – Enjoy a cooler environment in summer thanks to HOOMEE! HOOMEE seals around your open window and then zips around the nozzle of your hose and blocks the return flow of warm air, so that your mobile air conditioning unit can be more efficient and cools your room in less time.
  • REDUCE ENERGY CONSUMPTION - HOOMEE loves the Earth! This window seal contributes to reduce energy consumption and to lower carbon dioxide emissions, which is particularly high in summer due to the massive use of air conditioning. Preventing warm air circulating in your room, Hoomee window seal helps you save money on electrical bills!
  • EASY TO INSTALL – NO NEED FOR DRILLING HOLES . You don’t have to buy window kits, adapters for your hose or additional tools. All you need comes with your HOOMEE Window Seal! Simply apply the adhesive hook tape to the inside of your window frame and to the window itself. Attach the window seal to the hook tape. Then, open the zip on the window seal and place your air conditioner hose out of the window. At the end, close the zip tightly around the hose. Simple as it is.
  • UNIVERSAL - Suitable for all portable air conditioners and tumble dryersregardless of manufacturer. Whether for windows that open to the left or windows that open to the right, bottom hung windows or skylights, HOOMEE Window Seal will do the job. Fits window with a maximum perimeter of 400 CM.

5.0 out of 5 stars Can be a little tricky to install, but it works!
By Eli on 13 July 2019
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!
