This is my second purchase from this product, very satisfied! I didnt realize this one is slightly different from the one I got before until I received it. They work pretty much the same, both are very quite, large in size can fill up plenty water last for 2-3 days (I turn it on all night!), and I love the sleep mode which can avoid any disturbance when I sleep. One thing even better is that you can fill up the water from the top of the tank, so no need to upside down as you would need with many other humidifier including the one I got before. I like everything about this one, and white one looks so classic! Highly recommended!
