Query: DO NOT BUY!

We unfortunately bought this for our newborn and it is a disaster! He loves white noise, but this unit is making a lot more than white noise (as described over and over in other reviews here). It also is impossible to clean. Literally, the mold gets in places that I can't clean with a Q-tip. My baby's room now smells like mildew - a very strong smell. I'm very upset that this humidifier is a hazard to his health and wish I would've kept the box. PLEASE don't buy this. You will regret it! :(
