We had this lasko square shaped fan that we put in the kitchen when we cook to use as an exhaust but this is a total game changer. It fit right into our kitchen window and looks so much better! It can take the kitchen air and push it out but also can be used to being the fresh air in. Installation is a piece of cake and doesn’t require special tools! Easy to use and not complicated by unnecessary buttons. Stays out of the way since it sits in the window and not on the floor! Would totally recommend!
