Ok now I've come to a block. I wanted to install a humidifier directly on the furnace so I asked for advise. I had a proffessional company explain that putting one on the furnace is a waste of time. It will rot/rust my furnace and I should go with a floor unit?? So... I ask for a second opinion from a second company. They said the exact opposite? Both companies had their pro's and con's and I did not get either trying to sell their equipment to me. I asked only for advise. Ok... there are only two companies in my town... Ug-g. I'm asking for a third opinion. Help break the tie.. please... my nose is bleeding from the dry air in my house as I speak!

Well until you decide,, boil some water on your cook stove,, it will make a difference ,better than nothing,, as for the opinion,, I think the portable job that sit in the floor or on the sink top do wonderful, just a little aggravating,, having to keep water in them,, but can be moved from room to room,, the ones you add to furnace just don`t seem to last very long,plus the big bucks it cost now a days,, so my vote is against the furnace installed units
