I am really impressed with this excellent quality humidifier. It is easy to use and it really works well. I have a tendency to get very dry skin, cracked lips, and dry nasal passages during the summer months with the a/c running. The air is always too dry inside. I decided to give a humidifier a chance. This was my first experience with one. I am thrilled to have found the Levoit Classic Humidifier. This has made such a difference for me. No more dryness in the air. This puts out the perfect amount of moisture. I feel much better when using the humidifier. I plan on using it during the winter months as well when the humidity is low and I have the windows open. This is a really great product with awesome features that I would definitely recommend.
