With three sizes (300cm, 400cm, 500cm) to fit windows of different sizes, this portable air conditioner sealing device from the Gruntbear brand is easy to install and helps the hot air produced by the air conditioner to go out of the window, keeping the cool air inside and maintaining a comfortable room temperature.

Gruntbear has wholeheartedly designed and manufactured these simple and practical air conditioning tools to keep you cool during the summer.

The Gruntbear Portable Air Conditioner Window Seal effectively expels the hot air produced by the air conditioner out of the window, keeping the cold air inside and maintaining a cool room for a long time. This device is made of durable nylon material that can effectively block the entry of hot air, allowing your room to cool down quickly, enhancing the cooling performance of the AC, helping to reduce energy consumption, CO2 emissions, and your power bills.

The Gruntbear air conditioner seals are also made of waterproof nylon material, making them suitable for use even on rainy days, allowing you to create a cool space on sweltering summer days.

No drilling or tools are required for installation. Everything you need is provided by Gruntbear. Simply tape the AC seal kit to the inside of the window frame and to the window, place the AC hose out of the window, zip it up, and secure it with a zip tie. You can open or close the window at any time without removing the window seal.

The 300cm Air Conditioning Seal Kit is suitable for both push-out and pull-in window types and will fit windows up to 118 inches in circumference. It is suitable for skylights, awning windows, casement windows, or crank-out windows that open to the left or to the right, but not suitable for sliding windows, vertical push-pull windows, or stereo revolving windows.

To measure the size of your window, calculate the total length of the four sides of the window. If the total length is less than or equal to 400cm, select the 400cm size; if the total length is less than or equal to 300cm, select the 300cm size; if the total length is less than or equal to 500cm, select the 500cm size. Choose the size that is longer or closer to the length of your window.

The curved part of the window seal is the red, wide side, and the straight part is the blue, narrow side. The blue dots represent the middle of the window seal and the middle of the window casement.

The Gruntbear Portable Air Conditioner Window Seal Kit contains: 1 window seal, 1 magic tape, 3 cable ties, and 1 user manual.
