Stop warm air coming back in and keep cool air inside with this universal window seal for portable air conditioners and tumble dryers. The 400cm length fits a wide range of window openings (max perimeter 300cm) and works with bottom-hung, side-hung, and skylight windows. Easy to install without tools – just attach the hook and loop tape, fit the seal, and zip it closed around your exhaust hose. It blocks insects, dust, and rain, helps your air conditioner cool faster, and can save money on energy bills. Reusable and removable, so you can pack it away after summer and re-install next year.
