Humidifiers spread water vapor in the air
From a scientific perspective, there is no different between ultrasonic and hydrosonic humidifiers. Although the two terms do differ slightly, they both describe a process whereby water is turned into a gas using ultrasonic waves to spread energy throughout a fluid.
Humidifiers
Humidifers are designed to raised the humidity within an enclosed space. They operate by adding water molecules to the air, increasing the presence of water in a room. People use humidifiers in dry climates, when the body can benefit from increased moisture, especially at night when water intake lessens. In order to work, humidifiers need to turn a supply of water into water vapor. This can be done in a variety of ways, but one of the most popular is through ultrasonic waves.
Ultrasonic Process
Ultrasonic waves are sound waves that operate beyond the range the human hearing. All sound waves are in fact pressure waves that move through materials and substances due to some kind of force exerted at the source of the waves. Ultrasonic waves are pressure forces that have an extremely high frequency, moving very fast through the substances. While humans may not be able hear these sounds, they can control their effects: ultrasonic frequencies are so strong and fast that they tend to vibrate substances around them, imparting energy. When this affect is applied to fluids, it is possible that some molecules of these fluids will be vibrated so much they will gain enough energy to break free and float away as a gas. This brings us to hydrosonic activities.
Hydrosonic Differences
Hydrosonic means nothing more than applying the ultrasonic process in water. Pressure waves are created that vibrate the water so much that water molecules break free and enter the air as mist. So while humidifiers may be refered to as "ultrasonic" or "hydrosonic", the same process is being referred to, the application of ultrasonic waves in water. This is known in scientific circles as cavitation.
Cavitation
Cavitation is an advanced ultrasonic activity used when preparing cell solutions. It is extremely destructive to cell structures and a very power form of ultrasonic vibration that can also be used to change water from its liquid state to a gas. In cavitation, a probe or similar device vibrates very quickly in a fluid solution like water. These vibration pushe molecules away from the probe with their force. The molecules are jostled away for a moment, creating an air bubble or cavity, then collapse back down due to gravity. The force of their collapse creates more cavities in the surrounding water, which in turn collapse and spread the force in a ripple effect. This is how ultrasonic activity can be spread throughout a humidifier.
Other Humidifiers
Other humidifiers use a slightly more complicated process where water is heated until it is turned into steam, which is then propelled out into the surrounding air. These systems tend to cost a little more, since this process is more effective at increasing the overal humidity of the room.
