When I was little I remember having a humidifier that put out so much steam it was hard to get around because it had so much coming out of it, my how things have changed. When I got this unit I was hoping for the came effect however that was not the case. Steam barely comes out of it at all, now on the box it does state that if you aren't getting the flow of steam that you want to add salt to the water. Yes that does make the steam start to roll out of it good, only problem is that is will steam itself out very quickly. When I get the steam the way I want it won't even last 7 hours.If you have a small area and aren't looking for that much steam then this might be okay, I will be bringing this to my office to use. However if you have a larger room and like to have a lot of steam then this is not the product for you. Take the money you would spend on this and put it toward a better machine.
