Looking into getting a whole house humidifier installed, and debating between the bypass-type as opposed to steam. I am mostly concerned about effectivity of the system...I've heard mixed reviews on whether or not the bypass type does much at all considering the water use of about 20 gallons a day. The water usage doesn't bother me too much, although the cleanliness of the filter element does on top of whether or not it would be able to get the house up to the levels I'm hoping for. Right now I've got 5 sensors throughout the house measuring at about 35% or so, and the air will get considerably more dry as winter goes on. A target of 50% would be great, but if I could maintain close to 40% I'd be happy. I have heard the steam units are more effective and use less water. Can anyone with either system type installed share some observations?
