What is an Ultrasonic Humidifier?

Most people have heard of ultrasound machines that are used with medical imaging that allows doctors to see internal organs, joints, muscles, forming babies, and are very helpful in determining a diagnosis for the patient. However, not as many people know about ultrasonic humidifiers. An ultrasonic humidifier is one that uses a ceramic diaphragm which vibrates at a frequency of over 20,000Hz which create drops of water that are forced out of the humidifier by a small fan.

The humidifier contains a reservoir which holds the water that is then expelled into the room by using a very small metal plate vibrating at the ultrasonic frequency. These vibrations of the plate are so strong that they are able to fracture the drops of water in the container until they become a cool fog, or vapor. Once the water droplets are converted to vapor, they are discharged into the room as a very fine, undetectable mist. This helps balance the humidity in the room so that it is much healthier for the humans and the pets which are in the room.

Benefits of an Ultrasonic Humidifier

  • Cost – Although, generally ultrasonic humidifiers are slightly more expensive that other types of humidifiers, but many of the higher end models emit either warm or cold mist options.
