We are having trouble with our humidifier leaving a film on our furniture. Just bought the unit this weekend at Sears ultrasonic model very quiet and seems to work very well but the wife is finding a film or haze on furniture near the humidifier. We have an insert that we burn 24/7 so we need a way to replace some of the moisture in the air. I have one of those 1/2 pot steamer deals on top of the insert from Condar but it adds very little moisture so we need an additional source. Any ideas? This forum has been a great source of ideas so I appreciate any help you can offer.
