I am very impressed with this humidifier! Living in Indiana in the winter, the air in the house is so dry and cause my son to have nose bleeds, So i got this HUME humidifier to see if it helps. So far it has helped tons. It adds just enough moisture in the air. It does put out a nice cold breeze, So if your like me and get cold very easy, You will have to set it away from you. This humidifier holds 3.5 liters. So it last for about 12 hours depending on the settings. It is super easy to clean. It has a rotating mist control knob gives you the flexibility to adjust moisture output to how you like it. I love that it is also silent, makes it get for a child room. Over all i really love the HUME humidifier. It has brought me and my family relief from the dry air.
