MOEGFY
Why we love it
  • Enhances cooling efficiency.
  • Saves energy costs.
  • Easy installation guide.
Main Highlights
  • 【Efficiently Expel Hot Air and Prevent Backflow】The air conditioning window kit helps to exhaust warm air from the air-conditioned room through aircon hose and prevent it from flowing back. It cools your room more effectively, reduces energy consumption, saves electricity costs, reduces carbon dioxide emissions, and protects the environment. What's more, the aircon window seal kit can also prevent flies and spiders from entering the room through the window.
  • 【Wide Application】Make sure to measure your window before purchasing to select the correct size. Specifically designed for mobile air conditioners, drum dryers, and exhaust dryers, our AC window seal kit enables these devices to operate more efficiently by expelling hot air even with the window open. Suitable for tilt and casement windows, but not compatible with sliding windows. Currently available in 6 sizes ranging from 300cm/400cm/500cm/560cm/600cm, with more sizes coming soon.
  • 【Easy Installation】Our product includes air conditioner window seal, instructions, adhesive tape, and cable ties (for securing the hose). No drilling or special tools are required. Simply follow the detailed instructions for a quick installation. Open your window slightly, affix the adhesive tape to the outer or inner frame, attach the air con window seal, and then secure the air conditioner hose in the window seal using the zipper. Use cable ties as needed to keep the hose in place.
  • 【Durable, Waterproof, and Windproof】Our window seal for AC unit is made of durable 210T polyester with a PU coating, providing waterproof and windproof protection. In addition to regulating air exchange, the air conditioning window seal kit also safeguards the indoor environment from dust, dirt, strong winds, sudden rain, and insects. Note: There may be a tiny gap between the zipper of the window seal and the air conditioner hose, but this does not affect its functionality.
  • 【Portable and Reusable】Our portable AC window vent kit is not disposable. After the summer season, simply clean it with water for reuse the following year (the packaging bag can be used for storage). designed with 2 double-ended zippers to adjust the opening size based on the hose diameter, making it suitable for single or dual-hose portable air conditioners. For any questions or concerns, feel free to reach out to us.

Why we love it
  • Improves cooling efficiency.
  • Reduces energy bills.
  • Installation is tool-free.
Main Highlights
  • Superior Cooling & Energy Efficiency:Stop the sweltering summer heat from ruining your indoor comfort. This premium window seal creates a firm thermal barrier that blocks hot outdoor air from entering and prevents expensive cold air from escaping. By streamlining your AC unit's performance, it ensures your room reaches the perfect temperature faster while significantly reducing energy consumption and electricity bills.
  • Upgraded Non-Slip Dual Zipper Design:Featuring two pairs of high-quality, two-way zippers, our seal is specifically engineered for both single and dual-hose units. The innovative non-slip zipper structure, combined with the included cable ties, ensures the exhaust pipes are locked firmly in place. This prevents the hose from shifting or sliding, maintaining a 100% airtight seal for maximum cooling power.
  • Weatherproof 210D Fabric with PU Coating:Constructed from thickened 210D high-density polyester, this air conditioner window seal features a professional waterproof PU coating. It is built to withstand the unpredictable British weather, providing a robust shield against heavy rain, wind, and dust. The high-density weave also acts as a reliable barrier against insects and rodents, keeping your living space clean and pest-free.
  • Advanced Residue-Free Adhesive Tape:We prioritise the integrity of your home surfaces. Our kit includes a premium hook-and-loop tape with a neat, dense hook side for a more secure grip. The ultra-strong adhesive backing ensures it stays put throughout the hottest days, yet it is specially formulated to peel off smoothly without leaving any sticky residue or causing damage to your window frames when the season ends.
  • Universal Fit & Easy Maintenance:This 400cm seal is a versatile solution for most UK casement, top-hung, and tilt windows. Installation is completely tool-free and takes only minutes with no drilling required. The fabric is fully washable and reusable—simply remove it at the end of summer, wash away the dust, and store it for next year. It is the cost-effective and sustainable choice for every modern household.
