Keep Cool Air In & Hot Air Out with This Easy-Install AC Window Seal
Tired of your portable air conditioner struggling to cool the room because hot air keeps sneaking back in? This Flexible Cloth AC Window Seal creates a snug, weatherproof barrier between your window frame and your portable AC or tumble dryer exhaust hose — so your unit works more efficiently and your energy bills stay lower. Made in China.
Why You'll Love It
- Stops Hot Air Infiltration: The sealed cloth panel keeps warm outdoor air from re-entering your room, letting your portable AC cool more effectively and run less often — saving you on electricity costs.
- Reduces Energy Waste: By minimizing the exchange of indoor and outdoor air, this seal helps lower overall energy consumption and reduces your carbon footprint, especially during peak summer cooling season.
- Weatherproof & Dust-Blocking: The durable cloth construction keeps out not just warm air, but also dust, light rain, and insects — even when your window is partially open for the hose.
- Zipper-Equipped for Easy Use: A smooth zipper lets you feed your AC exhaust hose through in seconds. Close the zip tightly around the hose for a near-airtight seal. Open it up just as quickly when you're done.
- No Tools, No Hassle Installation: Simply press the included adhesive hook tape to the inside of your window frame and window panel, attach the cloth seal, and you're set. No drilling, no permanent modifications.
- Universal Compatibility: Works with virtually all portable air conditioners and tumble dryers. Compatible with windows that open left or right, bottom-hung windows, and skylights.
- Multiple Size Options: Available in 3 M, 4 M, 5 M, 5.6 M, and 6 M lengths (approximately 118–236 inches) to fit a wide range of window widths.

Frequently Asked Questions
Q: What window types is this portable AC window seal compatible with?
A: This flexible cloth AC window seal is designed for universal use. It fits windows that open to the left or right, bottom-hung windows, and skylights. The adhesive hook tape works on most standard window frames, and the multiple size options (3 M to 6 M) ensure you can find the right fit for your window width.
Q: Will the adhesive hook tape damage my window frame when removed?
A: The adhesive hook tape is designed for clean, residue-free removal. However, as with all adhesive products, results can vary depending on your window frame surface (painted wood, PVC, aluminum, etc.). We recommend testing in a small inconspicuous area first if you are concerned about your specific frame material.
Q: Can this cloth window seal be used with tumble dryers as well as portable air conditioners?
A: Yes! This versatile window seal cloth is compatible with both portable air conditioners and tumble dryers. Any appliance that requires venting an exhaust hose out of a window can benefit from this seal, helping prevent warm, moist air from re-entering your home.
Q: How do I choose the right size for my window?
A: Measure the total width of your window opening where the seal needs to span. Choose a size that meets or slightly exceeds that measurement — you can fold or trim excess fabric if needed. Available lengths are 3 M (~118 in), 4 M (~157 in), 5 M (~197 in), 5.6 M (~220 in), and 6 M (~236 in).
