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 400 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 | |---------------|-------| | ASIN | B08B1BQJ9J | | Air Conditioner Application | Air Conditioning | | Best Sellers Rank | 122,040 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 64 in Air Conditioner Parts & Accessories | | Brand Name | LYUNIT | | Colour | White | | Compressor Type | rotary_scroll | | Control Method | Remote | | Controller Type | Touch Control | | Core Material | Copper | | Country Of Origin | China | | Customer Reviews | 4.1 4.1 out of 5 stars (1,257) | | Efficiency | A | | Form Factor | Seal with Zipper | | Included Components | 400 cm window seal + magic tape | | Installation Type | Window | | Inverter Type | No Inverter | | Is Electric | Yes | | Is Outdoor Unit Required | No | | Is Product Cordless | No | | Manufacturer | shenzhenshipenghaoanquanjishushiwuyouxiangongsi | | Model Name | KTB | | Model Number | KTB | | Number Of Circuits | 1 | | Operating Mode | Cooling | | Power Source | Corded Electric | | Seasonal Energy Efficiency Ratio (SEER) | 5 | | Special Features | Waterproof, Easy To Install, Universal, Portable | | UPC | 783902063891 | | Warranty Type | Limited | | Window Opening Maximum Height | 100 Centimetres | | Window Opening Maximum Width | 127 Centimetres | | Window Opening Minimum Height | 24 Inches | | Window Opening Minimum Width | 100 Centimetres | ## Product Details - **Brand:** LYUNIT - **Colour:** White - **Control method:** Remote - **Form factor:** Seal with Zipper - **Inverter type:** No Inverter - **Model name:** KTB - **Power source:** Corded Electric - **Seasonal energy efficiency ratio (SEER):** 5 - **Special feature:** Waterproof, Easy To Install, Universal, Portable - **Warranty type:** Limited ## Images ![AC Window Seal Portable Universal Window Seal Kit 400cm/158Inch - Image 1](https://m.media-amazon.com/images/I/71gd131L2AL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - AC Window Seal, LYUNIT 400cm/158Inch Portable Universal Window Seal Kit for Mobile Air Conditioner Unit & Tumble Dryer, Hot Air Stop Air Exchange Guards, Easy to Install-With Zip - Air Conditioning Unit Portable Air Conditioner 9000 BTU 4-in-1 Dehumidifier, Cooling Fan with 2 Speeds, Digital Display & Remote Control, Window Kit, 24 Hour Timer for Room Up to 269sq.ft --- ## 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.gr/products/414934466-ac-window-seal-portable-universal-window-seal-kit-400cm-158inch](https://www.desertcart.gr/products/414934466-ac-window-seal-portable-universal-window-seal-kit-400cm-158inch) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-09-27*
