This is overall a great humidifier! I was very concerned bringing my new baby home to our central AC unit because the air is so dry and so often i experience dry throat and my sinuses get irritated for lack of adequate moisture. We have a diffuser but it wasn't doing what we needed to moisten the air.
What i love about this humidifier:
1. It holds a sufficient amount of water and lasts through the entire night and long through the day before it needs to be refilled with water.
2. It moistens the air very well to help with dry airways.
3. It is very quiet and the lights are subtle, not anything to wake a sleeping baby. I love that!
The challenges of this humidifier:
1. It will leave certain surfaces looking dusty after the mist has settled, depending on how close the humidifier is to the surface and the hardness of the water used in it.
2. When the water level is really low sometimes the sensor in the humidifier doesn't detect that there is water in there and so it will stop misting, until you tilt it or add more water.
3. In order to smell the essential oils you've put in the dispenser slot, you would have to add more each day.
Overall, for me the pros outweighs the cons. For the problem that this item solves. I would purchase it again.
