It really has to do with the proper amount of airflow in cfms to carry the steam away and you must follow the install info EXACTLY so the steam does not hit the duct and condense. You are going to likely need the RO reverse osmosis water filter kit they sell for it as well as they have had a lot of problems with scale buildup and failures. Do you REALLY need that amount of humidity? A bypass unit may do all you need and Honeywell has a 12 gal/day and a larger 17gal/day TrueEase bypass model now.
