I received my humidifier an I was excited and to try it out. It was not hard to Set up but was easy and quick. It has been running now for a few days to really see how it works and I can tell a big difference in the living room because I have a dog. I have use purified water in it and I have not had an issue with it so far. I try to clean it every weekend with soap and water. I also used the scented oils and it will have the whole house smelling so clean and refreshing.
