A humidifier adds water vapor to the air to increase humidity.
How a humidifier works
The humidifier unit uses a humidity-sensing control that cycles the humidifier on and off and a water panel that adds water vapor to the circulated air when needed. Relative humidity is the amount of moisture in the air expressed as a percentage of the maximum amount that the air is capable of holding at a specific temperature. In dry air conditions, the sensor tracks that percentage and adjusts the amount of added water vapor, giving your skin the moisture it needs and helping to keep any personal belongings, such as wood floors, furnishings, and keepsakes, from drying out. In essence, it’s one more way Trane makes your home more comfortable all year long.
