I purchased this item for my granddaughter who has a very dry stuffy apartment that has caused her and her son some health issues. After using this humidifier, she and her 2 year old son are doing much better. I plan to purchase another one for another room in her apartment. She says its has helped them tremendously and they feel much better. They are able to breathe better, no more dry eyes and noses, and no more chest congestion. I looked at several humidifiers but this one had some good reviews so I decided to give it a try. I am so glad I did.
