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.

Since ultrasonic nebulizers don’t compress air, they operate very quietly, 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).

CAREFULLY DESIGNED TO PROVIDE IMMEDIATE, NATURAL RESPIRATORY RELIEF: Breathing cool, fine mist provides immediate relief by lessening discomfort in your respiratory tract. Helps to reduce inflammation, relieve nasal congestion and sinus pressure. You can feel the desired relief in just 5-10 minutes of the session. Improve your ability to breathe and wake up refreshed.
ADVANCED ULTRASONIC TECHNOLOGY: The superfine cool mist, instantly produced by the use of ultrasonic vibration, can be easily inhaled into the alveolus and bronchial tree. Because of the smaller aerosol particles, such mist deeply penetrates into the airway, thus providing effective symptomatic relief for respiratory conditions.
HANDHELD, COMPACT AND LIGHTWEIGHT MODEL: one of the smallest and lightest ultrasonic inhaler solutions, weighing approximately 5.3 ounces (150 g) with dimensions 5.5 in (height) x 3.1 in (width) x 2.1 in (depth). It easily fits in a briefcase or backpack and much more comfortable to carry and use, unlike heavy and bulky traditional machines.
WHISPER QUIET OPERATION: the ultrasonic technology provides virtually silent operation of the device and ensures the comfortable conditions of use. There's no need to worry about the generated noise level, as in the case with similar compressor based solutions.
SAFE TO USE: The ultrasonic inhaler produces a cool, harmless mist, so you can't get burned. There is no heating source or boiling water involved, instead there is an advanced ultrasonic technology in place, making it safe to use by both adults and children.
