How a Whole-Home Humidifier or Dehumidifier Works
The humidifier utilizes a pad and rotating drum or steaming system to help with moisture levels. It starts by drawing water from an external source, like a tap or a reservoir, and then vaporizing it into the indoor air. As the water vapor rises, it adds more moisture to the home’s atmosphere. The amount of moisture in the air is monitored by a humidity sensor so that you can adjust the level of humidity in your home to the level of comfort you desire. The humidity sensor also helps the humidifier understand when it needs to turn off after the desired level has been reached.
Meanwhile, a dehumidifier reverses this process and draws in wet air. It utilizes a fan to force this air over refrigerated evaporator coils, which cools it down. This condenses. The dehumidifier then transfers the extra moisture into a pan or drain. For most whole-home systems, this moisture is drained out and away from your home.
Both systems are more effective than their compact equivalents, which can only treat a single room at a time. A whole-home system also requires much less upkeep than a lightweight dehumidifier or humidifier.
