This has been set up in my kids room and can tell a huge difference. They don't wake up all stuffy anymore. It's easy to set up and fill with water. It has the direction outlet so I am able to control where it comes out at. I love that there is no filter that I have to keep spending money on to replace. It has a tray for essential oils which I love to add. Best of all it is quiet and they don't complain about the sound being too loud.
