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

The product is exactly the same as the product page. Advantages: 1. Easy to install2. Reduces airflow. Disadvantages: 1. It is not airtight, cold air will flow through it but at a slower rate.2. The inner material makes rustling noises when the outside air is blown. I don't notice it too much except when I'm trying to sleep. I'm not sure why the interior material is supposed to make noise. It's much better than nothing, but I think an external case is required. The inner lid appears to be designed to look good when not in use. This is my opinion, your mileage may vary.
