How a whole-house humidifier works
A whole-house humidifier attaches to your ductwork or furnace and adds moisture to the air circulating through your home. Types include bypass, fan-powered and steam units, each with different capacity, cost and maintenance needs.
What installation involves
Installers connect the unit to the duct system, a water supply and a drain, and add a humidistat or control. Pads, water panels or other parts need regular maintenance.
Humidity balance matters
Too little humidity can feel dry, while too much can encourage condensation and mold. A professional can recommend a target for your home and climate.
