This Pro Breeze 500cm Window Seal Kit solves the biggest hassle of running a portable air conditioner: venting the exhaust hose neatly while keeping hot air out. Built for hinged windows, it fits all portable air conditioner and tumble dryer exhaust hoses, with an adjustable zip opening that closes tightly around any hose size for a near-airtight seal. The extra-thick waterproof fabric forms a temperature barrier, reflecting sunlight and stopping the warm outside air from leaking back in and undoing your cooling. That matters because a poorly sealed window can waste much of a portable AC's cooling capacity and push up your running cost per hour. At just 300g it is light, installs in minutes with no tools required, and removes just as easily when the weather cools. If you own a single-hose portable air conditioner, a proper window venting kit like this is essential, since these units must exhaust warm air outdoors to cool effectively. A simple, low-cost upgrade that makes any portable AC noticeably more efficient.

Highlights

  • Fits all portable AC and tumble dryer exhaust hoses
  • Designed for hinged windows
  • Extra-thick waterproof, heat-blocking fabric
  • Adjustable zip opening for any hose size
