I got this because of all the ones on KOREAN NOVELAS! I was wondering why the hospital scenes always have a machine that spews out fog. So this was it!I learned that Humidifier therapy adds moisture to the air to prevent dryness that can cause irritation in many parts of the body. Humidifiers can be particularly effective for treating dryness of the skin, nose, throat, and lips. They can also ease some of the symptoms caused by the flu or common cold. Thank you LGEI!
