I bought an expensive one before from other brands, however, it didn't worth the money. My room still gets very dry and every morning when I work up My nose was like burning. My throat also don't feel well. Then my friends recommend this to me. I caught sight of this product at my friend's home. It's white and very beautiful. The most important thing is it's very efficient. I use the hygrometer to test it. Before I use, the humidity is 30. After one hour, with the max mode, It's 60. Super super-efficient. If someone else ask me what humidifier I recommend, I will tell him this one without hesitation. Good product.
