Review on 🌬️ COSFLY Indoor Air Conditioner Cover: AC Unit Covers for Inside - 21 x 15 x 3 inches (L x H x D) by Lauren Walton

I chose this case from half a dozen others I researched. It replaced the thinner Frost King cover we've been using in NE Pennsylvania for the past few winters. We have a Friedrich AC air conditioner measuring about 23.5" x 13" so I chose the medium size. After inspecting this cover, I noticed that the quality and thickness of the materials used do a great job of preventing drafts. Since I had room for these and some extra cover insulation, I taped a 1.5 inch piece of recycled cotton to the front of the air conditioner. to run through the cord. I cocked the lid and tightened the laces on either side to finish the job. It fits almost perfectly and I'm sure it will make a great barrier against cold outside air. I plan to use the same insulation on the outside of the air conditioner before replacing the cover.
