Title: Not happy at all
Review: I bought this and plugged it in and NO vapor came out at all. Then I read further and thought it may be an evaporative humidifier (although it didn't say so on the box or anywhere else but the pamphlet). But apprently that means there is no mist that you can see visibly but the water goes through the filter and emits moist air and the only way you know it is working is when the water level goes down and the room feels moister. Well I had it on all day and the water level went down like an 18th of an inch if that and the noise on the lowest setting was so loud we had to shut it off at night when we needed it most. Didn't notice any difference in the moisture level in my kids room even after running all day. MAybe mine was defective but I won't try it again.
