It is easy to use and doesn't take up too much space. I do feel like it works great because my husband and I have both mentioned the feeling when we wake up not stuffy like before. Plus, I love knowing it is cleaning, deodorizing and moisturizing the air in my home! I can tell the difference with food smells after cooking, it's less noticeable. I have a very sensitive nose for smells and I love cooking with onions but hate the smell and feel like this helps with that. If you're looking for clean, fresh smelling air I suggest this. Also wanted to mention it's not too loud either and has a blinking blue light when needing to add more water/salt. I've usually fill it about the same time of day and run it almost all day most days. Good quality, easy to use, and works!
