Featuring a no-drill adhesive installation and a robust zipper closure, it prevents warm air infiltration, insect entry, and rainwater leaks. Compatible with most standard windows (excluding side-sliders), it supports eco-conscious energy savings by reducing AC workload and carbon emissions, making it a smart, easy upgrade for any modern home. ## Features - Improve Cooling-Keep Cool: The sealing of the window increases the cooling performance of the air conditioner. This reduces general energy consumption, as the room cools down faster and maintains a stable temperature in the long term. At the same time, it can prevent the flying insects and spiders from entering the room through the window or window seam, and also prevents the entry of rainwater. - Save Energy-Protect the Earth: Loves the earth, this mobile air conditioning 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. LYUNIT Window seals for mobile air conditioners are the perfect choice for household. It can save your funds in electricity and environmental protection. - Easy to Install-No Drilling Required: Stick the supplied adhesive tape to the window frame, attach the air conditioning window seal to the window and frame and you're done. The window seal for air conditioning reliably prevents the return flow of warm outside air into the air-conditioned interior and directs the warm air from the air conditioner to the outside. - Super Zipper Function: For maximum hold of the climate hose. The window seal has extra strong zips that prevent automatic opening of the closure when using the climate hose. Additional support and attachment are included with the product. And you can open or close the window at any time without removing the window seal. - General AC Window Seal: The air conditioner window seal is suitable for all portable air conditioners. The material of the window seal air conditioner is durable, UV-resistant. The air conditioner window seal fits window with a maximum perimeter of 300 CM. It can also be used in a variety of other devices including dehumidifiers or dryers which come with a flexible exhaust hose. ## Technical Specifications | Specification | Value | |---------------|-------| | Air Conditioner Application | Mobile | | Asin | B09Q5Y4DXZ | | Best Sellers Rank | 190,502 in Home & Kitchen (See Top 100 in Home & Kitchen) 74 in Air Conditioner Parts & Accessories | | Brand Name | LYUNIT | | Colour | White | | Compressor Type | rotary_scroll | | Control Method | Remote | | Controller Type | Touch Control | | Core Material | Lightweight material | | Country Of Origin | China | | Customer Reviews | 4.1 4.1 out of 5 stars (1,274) 4.1 out of 5 stars | | Efficiency | A | | Form Factor | Window Seal for Portable Air Conditioners with Retractable Zipper | | Included Components | Adhesive Tape, Zipper, Cable Ties | | Installation Type | Window | | Inverter Type | No Inverter | | Is Outdoor Unit Required | No | | Is Product Cordless | No | | Manufacturer | shenzhenshipenghaoanquanjishushiwuyouxiangongsi | | Model Name | KTB | | Model Number | KTB | | Number Of Circuits | 1 | | Number Of Power Levels | 1 | | Number Of Tubes | 1 | | Operating Mode | Cooling | | Power Source | Corded Electric | | Room Type | Bedroom | | Seasonal Energy Efficiency Ratio Seer | 14 | | Special Features | Waterproof, Easy To Install, Universal, Portable | | Start Year | 2022 | | Unit Count | 1.0 count | | Warranty Type | Limited | | Window Opening Maximum Height | 300 Centimetres | | Window Opening Maximum Width | 150 Centimetres | | Window Opening Minimum Height | 20 Inches | | Window Opening Minimum Width | 150 Centimetres | ## Product Details - **Brand:** LYUNIT - **Colour:** White - **Control method:** Remote - **Form factor:** Window Seal for Portable Air Conditioners with Retractable Zipper - **Model name:** KTB - **Power source:** Corded Electric - **Seasonal energy efficiency ratio (SEER):** 14 - **Special feature:** Waterproof, Easy To Install, Universal, Portable - **Start year:** 2022 - **Warranty type:** Limited ## Images ![AC Window Seal Portable Universal Window Seal Kit 300cm/118Inch - Image 1](https://m.media-amazon.com/images/I/71gd131L2AL.jpg) ![AC Window Seal Portable Universal Window Seal Kit 300cm/118Inch - Image 2](https://m.media-amazon.com/images/I/61zvrxHsqaL.jpg) ![AC Window Seal Portable Universal Window Seal Kit 300cm/118Inch - Image 3](https://m.media-amazon.com/images/I/71phq8QTn6L.jpg) ![AC Window Seal Portable Universal Window Seal Kit 300cm/118Inch - Image 4](https://m.media-amazon.com/images/I/71VreXQ5xIL.jpg) ![AC Window Seal Portable Universal Window Seal Kit 300cm/118Inch - Image 5](https://m.media-amazon.com/images/I/712nzM391UL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Great On Ac Vented Fan Universal *by on Reviewed in the United Kingdom 22 August 2026* Needed for my ac fan and not to draw heat during this heatwave. Kept the ac cold air in while sealing out the heat. Easy to install and cheap 👌. ### ⭐⭐⭐⭐⭐ Easy to put and good zips! *by on Reviewed in the United Kingdom 18 August 2026* Very pleased with this. Easy to put on and does the job. You can close your window with it on so only remove during g the window. Very good. ### ⭐⭐⭐⭐ Works Well Once Installed Correctly *by on Reviewed in the United Kingdom 14 July 2026* This window seal does exactly what it's supposed to do and helps my portable air conditioner work much more efficiently by preventing warm air from coming back into the room.The reason I'm giving it 4 stars instead of 5 is that the installation wasn't as straightforward as I expected. The instructions left me a bit confused, and I struggled to fit it properly on the first attempt.After watching a couple of YouTube videos, I understood how it should be installed and managed to fit it without any problems. Once in place, it created a good seal around the window and AC hose, and the difference in cooling performance was noticeable.Overall, it's a good product and works well, but be prepared to spend a little time figuring out the installation if you've never used one before. ## Frequently Bought Together - LYUNIT AC Window Seal, 300cm/118Inch Portable Universal Window Seal Kit for Mobile Air Conditioner Unit & Tumble Dryer, Hot Air Stop Air Exchange Guards, Easy to Install-With Zip - 6 inch Plastic Blauberg 3m portable Air Conditioner venting duct hose extension kit. --- ## 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.sn/products/426294287-ac-window-seal-portable-universal-window-seal-kit-300cm-118inch](https://www.desertcart.sn/products/426294287-ac-window-seal-portable-universal-window-seal-kit-300cm-118inch) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-10-29*
