Review: Does the job well and easy to use - Bought this summer as the window seal that came with my AC didn’t fit. Easy to apply, and the white velcro blends in nicely. Added a shoelace to tie the zippers as a precaution with my cat. Without this seal, the AC barely worked — after adding it, the room felt much cooler, so it clearly keeps the hot air out.
Review: Instructions could be clearer, but it's not that hard to install and works ok. - Seems to work ok. Does it provide an airtight seal? No. Does it need to? No. Does it keep insects out? Yes. Are the instructions clear? No. Do you need them? Not really. Stick the tape around the window. Stick the tape around the frame. Attach the material to both - make sure the thickest bit of material is in the middle of the widest gap. Undo the zip, stick the pipe through and do up the zip, use the cable clips to keep it done up. That's all it needs really.

## Features

- 【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.

## Questions & Answers

**Q: Does this fitting work for outward facing windows? Notice the picture shows it for windows opening inwards**
A: My windows open outwards and this works fine.

**Q: How many parts does it come in, I would not be able to use it along the top of the window because it is too close to the ceiling?**
A: One long piece. You can’t cut due to the zip attached all the way.

**Q: Will it fit my windows that are 51cm across & 80cm length**
A: Most of these  nylon seals are "universal" you are not likely to get the photo  type fit  shown on PR materials,but you get an acceptable seal,I chose not to cut off excess material, the product fitted is functional rather than pretty.I achieved  a room temp of 16 degrees using one so it does make a good seal.Cant recall  the exact size  of the one I used, while ago now.

**Q: What comes out of the tube? Can I just connect it to a bucket?**
A: Hot air comes out of tube out of the window.if water comes out anywhere else it must be an dehumidifier mode. You can use a wee bucket but I have not had any water when using ac machine on dehumidifier on machine would let water come ou bottom hose connection. I would weekly make sure you have no water in machine by putting at angle and opening up valves. Hope this helps.
