AUGOLA Window Seal Kit for Portable AC & Tumble Dryers
4.3Our verdict
A window seal is the cheapest upgrade you can make to a portable air conditioner. This AUGOLA kit fits most windows with an adhesive-and-zip design, no tools required, and seals around the exhaust hose so the hot air you've pumped out stays out. It works for tumble-dryer venting too.
