I bought this air conditioner for the master bedroom. I usually run it on low speed, temperature 68 degrees, it cools very nicely and is reasonably quiet. I like how the air flow is up instead of into the room as cold air falls this cools everything down quickly. I can also direct the air flow left, center, or right. It has a air filter that is washable, also has a reminder when it needs to be cleaned. Remote control came with 2 AA batteries. It was easy to install, my husband didn't need any help lifting to put it in the window. Energy Star efficient.
