Our high-quality window seal for portable air conditioners ensures an efficient and comfortable indoor climate during the hot summer months. It's available in three different lengths: 300 cm, 400 cm, and 500 cm , so you can choose the perfect size for your window, skylight, or balcony door.
To do this, simply measure the three open sides of the window or optionally all four sides to ensure complete sealing.
For example, if your measurement result is approximately 390 cm, we recommend always rounding up to the next larger size and choosing the 400 cm seal .

The seal is made of waterproof, durable material (100% polyester) and protects your home not only from warm outside air, but also from unwanted pests such as mosquitoes or flies .
With a width of 40 cm, it is universally suitable for most common window types, such as tilt windows or windows with side opening to the inside or outside .
Important note: The seal is not suitable for sliding windows, casement windows with a central axis or windows with very deep installation where the air conditioning hose cannot be passed through.

The window seal can be installed quickly and easily – without drilling or additional tools.
It creates an airtight seal around the exhaust hose of your portable air conditioner, preventing warm air from flowing back into the room.
This not only increases the efficiency of your air conditioning system , but also helps to save energy and keep the room temperature consistently comfortable.
