The Clean Comfort HE Series Whole House Humidifiers use the principle that vapor (evaporated water) is created when warm air blows over a water-soaked area. As the vapor circulates, the relative humidity rises.

The humidity control monitors the relative humidity and activates the humidifier accordingly. The humidifier has a water supply that dispenses water evenly over a humidifier pad. The warm, dry air from the furnace passes over the humidifier pad and picks up the moist air to circulate it throughout your home.

Standard Features:

• Increases the relative humidity in your home, allowing you to
  lower the setting on your thermostat and still have the same
  comfort level.
• Easy-to-use humidity control included.
• Moisture control helps protect wood floors and furnishings.
• 5-Year Parts Limited Warranty. Complete warranty details
