As we make our way through the cooler months, one thing is certain — indoor air conditioner covers are a must-have. No one enjoys a drafty environment, and apartment-friendly window air conditioners are one of the leading reasons why your space might be feeling less than cozy this season. The easiest way to stop pesky drafts is with one of these handy covers. Used to block blustery winter air and debris from entering your home through your air conditioner’s vents, AC covers seamlessly wrap around the front of your unit to create the perfect protective layer. Most covers also feature double insulation to ensure proper draft protection, something that can help lower energy costs by 10 to 20 percent, according to the U.S. Department of Energy. Below, shop six of our favorite indoor air conditioner covers (as well as two additional products that’ll help insulate even the draftiest windows). Stay warm, folks!
