Never owned a humidifier, saw this was a air purifier, and, humidifier (combo), so it turned out great. The unit itself in the high setting is a little loud, but, tolerable (does have a low setting which is good if you want to sleep with it on). Had an issue with amount of dust in my small bedroom, this seemed to lower the dust build up drastically. Design is nice, really easy to operator, love how it doesn't have energy wasting LED's like other humidifiers on the market. Overall good product, has the upper hand since its an air purifier, and, humidifier. Thanks Phillips!
