Just as there are many different kinds of spaces requiring proper humidity, there are many different ways in which humidification can be provided to a building. Each type of system has advantages and disadvantages, and as can be imagined, the costs to operate each type of system vary tremendously.
Ultrasonic humidification, which is an adiabatic type of system, is just one type of method available. These systems are known for using very little energy, and experts state that they also provide high-quality moisture and close control of an environment while requiring little maintenance. However, other factors such as first cost and water quality also have to be considered when figuring out how an ultrasonic humidifier will affect a building's total operating costs.
