I have a quick question about the ultrasonic humidifiers. I need a humidifier for my bedroom, the air is too dry for myself. This is also where I keep my orchids. In the past I've had the regular warm mist humidifier. Since ultrasonics seem to be recommended I was going to purchase one of those this time. Since they put out a cool mist does this affect the temperature of a room at all?
Ok, I guess I have 2 questions really. It's mentioned that they are cheaper to run. But when you factor in filter costs or distilled water purchases are they really cheaper?
