Efficient exhaust of hot air – keep the room cool
This portable air conditioning sealing strip for windows connects between the window and the air conditioning hose, effectively directing hot air outdoors. It blocks outdoor heat and preserves the cold air indoors, helping to quickly cool down the room and maintain a pleasant and cool indoor climate.

Improves AC performance – energy-saving
Made of durable nylon material with excellent sealing capabilities. By preventing hot air from re-entering the room, the sealing strip increases the air conditioner's efficiency. It reduces both energy consumption and carbon dioxide emissions, saving electricity costs – a smart solution for energy efficiency.

Water-resistant and durable – withstands all weather
The waterproof nylon material means the sealing strip can be used even during rainy and humid summer days without problems. It prevents rainwater from penetrating, so you can enjoy a cool indoor climate even in heavy summer weather.

Tool-free installation – easy to use
No drilling or tools required. Simply attach the sealing strip to the window frame and window edge, insert the air conditioning hose through the opening, and close the zipper. During use, you do not need to remove the strip, and the window can still be opened and closed freely.

Reusable without adhesive residue
The sealing strip is easy to remove and reuse without affecting the window's function. After disassembly, it leaves no adhesive residue or marks. It can be stored and used again next summer, making it both cost-effective and environmentally friendly.

Wide range of applications – fits several window types
Compatible with openable windows such as casement windows, inward/outward tilting windows, skylights, and awning windows. Not suitable for sliding windows, vertical sliding windows, or 3D swivel windows. Check the window type before purchase.

Available in several sizes – adapt to window dimensions
Measure the circumference of three (a + b + c) or four sides (a + b + c + d) of the window before purchase.
– For circumference up to 300 cm, choose the 300 cm variant.
– For circumference up to 400 cm, choose the 400 cm variant.
Always choose a sealing strip with a length that corresponds to or slightly exceeds the window's circumference for the best sealing results.
