An ultrasonic nebulizer does not use compressed air like a traditional nebulizer machine. Instead, an ultrasonic nebulizer uses high frequency vibrations to aerosolize the medication into a very fine mist. Because ultrasonic nebulizers do not compress air, they operate without much noise, tend to be much smaller in size, and can fit in nearly any container. One of the best ultrasonic nebulizers (and one of the best nebulizer in general) is the Olex Ultra Sonic Nebulizer machine.
