An ultrasonic nebulizer, like the Silent Jet, uses water and high-frequency vibrations from the transducer to transform the medication into a mist that is then inhaled. This type of nebulizer has certain advantages: The mist particles created tend to be smaller and more uniform making it easier for the lungs to absorb the medication. In addition, as its name indicates, the ultrasonic Silent Jet is quieter in use. Since it is relatively small and light, above all in combination with the optional battery, it is highly suitable for use when travelling.
