I purchased this unit for my newborn son. My pediatrican recommended a cool mist humidifier and I thought this would be the perfect one for his nursery... It was in his nursery for approximatley 1 week when my husband noticed water on our sons dresser, my husband then looked in the back of the dresser and noticed that the unit had badly leaked and there was a noticeable puddle of water not only in the back of this dresser but when my husband opended his top drawer there was a good amount of water on his clothing and the water had also damaged our sons dresser drawers.... Needless to say my disappointment and shock that the unit was leaking but had ruined some of our sons clothes and brand new dresser/changing table... I do not recommend this unit at ALL !!! Spend the extra money and buy something else !!!
