My Sunbeam Ultrasonic Visible Mist humidifier worked great, EXCEPT it produced a dull haze in the air in the room and also deposited this hazy film on all the windows, furniture, appliances, tables and tile floors. I bought this model because it required no filters. Would not recommend this to anyone. Very dissatisfied with it's performance. It's going back to Home Depot tomorrow. What's up with this haze? It is brand new
