Watch a YouTube on how to put it up to get started, but its actually pretty simple. Has been up for a few weeks now & makes quite a difference. Review: Excellent - We had some plastic on the window and it was noisy, so we came to desertcart to look for something we could put up around the window. This was very easy to install. Just clean around the frame, put up the tape. Then put up the surround. It seals very well and we have been using our AC and there is no hot air coming back into the house. Very functional, great value for the money and the appearance is unobtrusive. Would highly recommend. ## Features - ❄❄ 【ENJOY COOL AIR IN SUMMER】 - Our air conditioner window seal blocks the return flow of warm air by locking the hose between the window frame and the window itself.

And it’s not a perfect seal around the hole you leave for the hose. I’ve ended up rigging up gardening twine to go through the zips and around the hose to pull tight and keep it all snug against the hose. And more gardening twine tied to the frame above to pull the hose up so it’s not exerting pressure on the fabric and pulling it down. It’ll do for now until I can figure out a better solution. A good improvement would be an elasticated hole for the hose to go through, rather than the zips. I’ve managed to set it up in a way where I can close the window and secure it when I need to. Obviously I can not open the window fully now unless I remove it, and I just can’t face sticking it all up again, so it will stay in place for the summer. I went for a slightly smaller size rather than have miles of extra material hanging down, and I have used the excess tape to stick a strip of cardboard over the gap. So all in all not perfect by a long way, but a heck of a lot better than trying to rig something up myself. Despite the awkwardness, and with a few adjustments, it’s working as it should and I can make my room ice cold with the portable air conditioning unit I bought. ## Frequently Bought Together - Air Conditioner Window Seal, Machine-YA Window Seal for Portable Air Conditioner and Tumble Dryer, Works with Every Mobile Air-Conditioning Unit, Air Exchange Guards With Zip and Hook Tape (400CM) - 6 inch Plastic Blauberg 3m portable Air Conditioner venting duct hose extension kit. - Inventor Portable Air Conditioning Unit Chilly, Powerful 9000BTU Mobile Air Conditioner, 3-1,Cooling, 2 Fan Speeds, Dehumidifier, Remote, 24 hr timer, for 215ft [Energy Class A](WEE/MM0449AA) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/314141341-air-conditioner-window-seal-machine-ya-window-seal-for-portable](https://www.desertcart.pt/products/314141341-air-conditioner-window-seal-machine-ya-window-seal-for-portable) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-18*
