Bought it for a 10 by 10 space and it kept the room UBER cold! My son would shut it off because the space would get so cold. I had the previous model and the door broke from opening to clean the filter. Therefore, it was nice to see they changed it to a pull out feature to clean the filter, which is better. However, it has no economy feature which would have been nice in order to save some money. Otherwise, very happy with the purchase.
