Query: I actually bought this twice!

Save yourself a lot of trouble and DON'T BUY THIS ONE! The first time I bought it, it worked for about 2 weeks, then had decreased output due to the black paint flaking off of the nebulizer (the part that makes the mist). So I returned it and bought another one...this one worked off and on for about a week and then never worked right after that, despite my careful cleaning and disinfecting, just like the owners manual instructs. I use it in my baby's room (very small room) and, after the first week, couldn't get the humidity above 20%. It's just not dependable, which is a pain when she wakes up constantly throughout the night sniffing and fussing due to dry air! I just ordered the Vornado 2.8 gal cool mist humidifier...hopefully that will work much better!
