Or is a marketing tool to make more money for the manufacturer...
You know, sometimes I think you are unyielding, and other times I just think you're an a**. Just because you don't need a humidifier on your machine doesn't mean others don't. No matter what others say here you just keep saying they don't need it. How nice it must be to know everything about everybody.
I don't use a machine that you're all discussing, but in the winter I need a humidifier when I sleep otherwise I wake up with huge sinus issues. Obviously I must be mistaken, it must be a marketing tool for my 40+ year old humidifier that my parents bought.
