FAQ:

Q: What is the best type of humidifier for the entire house?

A: For those who want to humidify several rooms, or a whole house, the top rated whole house humidifier is the Essick AirCare MA1201 (Est. $100). This evaporative console humidifier has a 3.6-gallon tank and can produce up to 12 gallons of moisture per day — enough to cover an area of 3,600 square feet.

Q: How do you install a humidifier?

A: Installing The Humidifier 1. Connect the wires of the humidifier to the solenoid of the humidistat (use the right size of wire nuts for safety). 2. Connect your humidifier to the hot water line – there are two ways to do this. You can either cut the water line and install a T fitting or use a saddle valve.

Q: How does a furnace-mounted home humidifier work?

A: A flow-through humidifier typically is mounted to the furnace’s cold-air return duct and connects to the hot-air supply off the furnace through a humidifier supply takeoff duct. The takeoff duct diverts some heated air into the humidifier, where it absorbs moisture from an evaporator pad before returning to the warm air stream through the cold-air return duct and furnace.
