I bought this for my baby's room and I had high expectations on this product. Before putting it in my baby's room, I decided to give it a test run in my room for a night, and I'm glad I did it. It was very quite at the beginning, and my only concern was the LED light, which I believe I should b e able to cover it later. However, during middle of the night, I was waken up by the water bubbling/dripping sound. I thought it was raining outside, but it turned out to be from this humidifier. I keep hearing the noise, and it surely disturbed my sleep. I'm glad I did not put it in my baby's room, otherwise, disturbing my baby's sleep will be a disaster for the whole family.
