Negative Positive
Title: noisy and moldy
Review: I thought this would be perfect for a bedroom. and maybe it is, as long as you don't plan to sleep! A full tank will run for 6-7 hours, but the machine is incredibly noisy for about the last hour, as the water level gets lower. The sound reminds me of an older model drip coffeemaker. also, the unit needs constant cleaning. About once a week, I had to take it apart and clean out slimy, yellow-ish much that accumulated in the bottom. Didn't make me feel too good about what I was breathing. Also, there's no way to regulate the moisture level, etc. It just goes until it's out of water. I've now replaced this with a different humidifier.
