Tired of feeling drafts around your window AC unit? These foam insulation panels are total game-changers! They measure 17 inches high by 9 inches wide and about 7/8 inch thick, but the cool part is you can easily trim them to fit your specific air conditioner. Made from high-density foam, they're soft yet durable and won't damage your AC unit. They basically fill those annoying gaps between your window frame and AC, blocking cold winter air from sneaking in and hot summer air from escaping. This not only makes your room more comfortable but can actually lower your energy bills since your heater or AC doesn't have to work as hard. They also help with noise reduction and keep out dust and pollen. Installation is super simple - just clean the surface, cut the panels to size if needed, peel off the adhesive backing, and stick them in place. The package comes with two panels, two U-shaped frames, and extra adhesive tape. They work with most window AC units from 5000 to 22000 BTU. Seriously, if you've noticed drafts or higher energy bills with your window AC, these inexpensive panels make a huge difference in comfort and efficiency throughout the year.
