Honestly - I love this device. Not only is it functional and does what it needs, but it looks amazing. The sleek white design with the blue LED touch buttons and indicators makes it look like an expensive piece in my dining room  living room area. It’s quiet and not bothering any of the 4 animals I have. I also have it on auto. If it is annoying to some people it has timers and fan settings. I’m going to be ordering some new filters soon so I have them ready when the red light comes on. 

Again, I really like this.
