This unit is meant to be mounted under your duct work. This works well if you don't have room for a traditional whole house humidifier that mounts to the side of your duct work. I used this for about a month and decided that a drum type humidifier would work better for me. Everything is included for you to install this in your home with the exception of the wire needed to run to the controller. This unit was $150 new. Message me with any questions.
